Inquix AI – AI Auto Responder for Contact Form 7

Never lose a lead to a slow reply. AI auto replies for Contact Form 7 — with AI included. No OpenAI account or API key required. Inquix AI answers Contact Form 7 inquiries in seconds with a personalized response based on what the visitor actually asked, your business information, your Knowledge Base and your brand voice. Instead of sending the same generic "we received your message" autoresponder to everyone, Inquix creates a useful reply that feels like your business answered personally — while the lead is still warm. Your contact form answers customers like you would — in seconds, not tomorrow. A real answer, not an autoresponder Traditional Contact Form 7 autoresponders send the same static message to every visitor. Inquix understands the visitor's question and generates a relevant response using your own business information, such as:

• Services
• Opening hours
• Frequently asked questions
• Policies
• Pricing information
• Company facts
• Other Knowledge Base content

Replies can follow your brand voice and respond in the visitor's language. The visitor gets an immediate, useful answer — giving you time to follow up personally without leaving the inquiry unanswered. AI included. No OpenAI account or API key required. Inquix is built as a finished service, not an AI toolkit. You do NOT need to:

• Create an OpenAI account
• Generate or manage an API key
• Add billing details to OpenAI
• Monitor separate AI usage costs
• Build or maintain AI workflows
• Connect Zapier, Make or other automation tools

The AI is built into Inquix and included in your plan. Install the plugin, connect your site, describe your business and start generating replies. Set up in minutes Inquix is designed so that you do not need AI or automation experience.

1. Install Inquix
2. Connect your site
3. Add information about your business
4. Enable Inquix for your Contact Form 7 form
5. Start generating personalized replies

No OpenAI setup. No API key. No separate AI infrastructure. Built around your business The better Inquix knows your business, the more useful its replies can be. Your Knowledge Base can contain information about your services, FAQs, opening hours, policies, pricing and other company-specific facts. Inquix combines that information with the visitor's actual message to create a response that is relevant to the inquiry — rather than a generic template. Your brand voice Configure how your business should sound. Inquix can use your preferred tone and business context so replies feel consistent with the way you communicate with customers. Automatic replies or Approval Mode You decide how much control you want. Automatic Mode Send the personalized reply immediately after the Contact Form 7 submission. Approval Mode Review, edit and approve every AI-generated response before it is delivered. This makes it possible to start with human oversight and move to automatic replies when you are comfortable. Professional email delivery Inquix AI replies are delivered through professional email infrastructure rather than relying only on your WordPress hosting server's email function. Reply-To routing allows the visitor to reply directly to your business, while the Inquix delivery infrastructure provides a more reliable email workflow. Built to be trusted with your inbox Inquix is designed as a managed service with safeguards around AI usage and delivery. Features include:

• Approval Mode
• Usage tracking and logs
• Daily and monthly usage limits
• Spam and abuse protection
• Managed AI infrastructure
• Professional email delivery
• EU-hosted infrastructure

Third-Party Services & Data Disclosure Inquix AI relies on the following third-party services to function. By installing, connecting your site, and enabling AI replies for a form, you consent to the data described below being transmitted to these services. No data leaves your site until you connect it and enable at least one form.

• Inquix API — When a visitor submits an enabled Contact Form 7 form, the submission (visitor name, email, and message), your configured prompt/business context, and any Knowledge Base excerpts are sent to the Inquix API (api.inquix.ai), which generates the reply using OpenAI's API under Inquix's account and delivers it by email. See the Inquix Privacy Policy (https://inquix.ai/privacy) and Terms (https://inquix.ai/terms), and OpenAI's Terms of Use (https://openai.com/policies/terms-of-use) and Privacy Policy (https://openai.com/policies/privacy-policy).
• Stripe (Pro subscriptions only) — If you upgrade to Pro or manage billing, you are redirected to Stripe Checkout or the Stripe Customer Portal. Payment details are entered on Stripe; no card data passes through your site or this plugin. See Stripe's Services Agreement and Privacy Policy.

1.2.0

• Changed: the Account Email field in onboarding is now prefilled with your WordPress email, so creating your free Inquix account is one click. The address stays editable.
• Changed: the first onboarding button now reads "Create free account & connect".

1.1.0

• Changed: AI replies are now included — no OpenAI account or API key needed.
• Removed: the onboarding OpenAI step was removed; existing stored keys are deleted on upgrade and no longer used.
• Changed: Preview & Test now allows 30 previews per day without using your monthly reply allowance.

1.0.2

• Changed: plugin renamed to "Inquix AI – AI Auto Responder for Contact Form 7"; refreshed short description, tags and directory introduction. No functional changes.

1.0.1

• Fixed: removed the Author URI plugin header — WordPress.org requires Plugin URI and Author URI to differ, and both pointed to inquix.ai. No functional change.

1.0.0

• First release in the WordPress.org Plugin Directory. Functionally identical to 0.14.12 — version milestone plus final screenshots and listing assets.

0.14.12

• Changed: Pro pricing is now shown as €29/month + VAT where applicable — VAT is calculated automatically at Stripe Checkout based on your country, and EU businesses with a valid VAT ID are reverse-charged.

0.14.11

• Changed: Pro is described as unlimited AI replies (*) with a clear footnote — a high monthly cap (currently 2,000 replies) applies for security, spam protection and abuse-protection purposes, and any customer can contact support to have their daily and monthly caps increased at no cost.

0.14.10

• Changed: Pro is now consistently described as a high-volume fair-use allowance (5,000 replies/month, raisable via support) instead of "unlimited" — matching the Terms of Service.
• Internal: removed two unused leftover files from the plugin package; legal links now point directly at the canonical Privacy Policy and Terms of Service pages.

0.14.9

• Fixed: if Inquix suspends a site, blocked replies are now logged as "Suspended" (with a matching filter in the Logs page) instead of the misleading "Quota Exceeded", and the admin notice explains the suspension instead of suggesting an upgrade.

0.14.8

• Internal: moved a documentation file out of the plugin package.

0.14.7

• Internal: industry definitions consolidated into a single registry — no visible changes; prevents settings-save issues when new industries are added.

0.14.6

• Fixed: on the Overview page, the "Upgrade" button in the Usage card no longer overlaps the text above it — it now sits on its own line, aligned.
• Fixed: admin notices no longer overlap the page-header Upgrade button (added the standard WordPress notice anchor).

0.14.5

• Added: the Overview page's Setup Status now shows whether you've added Knowledge Base content, with a link to add it — replies are more accurate with your business info.

0.14.4

• Fixed: saving AI Agent Settings with an empty Primary Language no longer switches replies to language guessing. An empty field now falls back to your site's language (auto-detected from the WordPress locale).

0.14.3

• Fixed: reaching your reply limit now shows a clear notice in the WordPress admin. Previously the notice was never displayed.
• Improved: the limit notice matches your plan — Free plan shows an Upgrade to Pro link, Pro plan explains the fair-use limit and how to contact support to raise it.
• Fixed: replies blocked by the daily fair-use limit are now logged as "quota exceeded" instead of "failed", with the actual reason shown in the Logs page.

0.14.2

• Fixed: API error messages are now shown correctly in the Logs page. Previously some backend errors (e.g. reaching the fair-use reply limit) appeared as the unhelpful text "Array" instead of the actual message.

0.14.1

• Improved: the Third-Party Services disclosure now explicitly lists the site language setting (locale) among the data stored by the Inquix API, matching what 0.14.0 sends.

0.14.0

• Added: the site's WordPress locale (e.g. sv_SE) is now included in the settings metadata sent to the Inquix API when you save AI Agent Settings, alongside the industry. Used in aggregate to understand where Inquix customers are located.

0.13.2

• Changed: the Disconnect button is now labelled "Disconnect & Delete Data" and asks for confirmation before proceeding — it removes your site and data from Inquix and resets the plugin, same as Delete Site Data.
• Changed: removed the "Email delivery configured" item from the Overview Setup Status — email delivery is no longer a setup step.

0.13.1

• Changed: Finish Setup on the Setup page now requires a successful Test Connection first; the Reconfigure button was removed (Update API Key reopens the wizard). New quick links on the Setup page: Auto-Replies On/Off (jumps to Sender Details) and Approval Mode & Inbox.

0.13.0

• Changed: the Setup page is now a 2-step wizard (Connect Account → OpenAI Key). The old Email Delivery step was removed — its auto-reply toggle lives in AI Agent Settings → Sender Details and its test email in Diagnostics.

0.12.0

• Added: a free-text box at the top of the Knowledge Base section (AI Agent Settings and setup wizard) — describe your business in your own words, no document or FAQ needed. The AI uses it together with any uploaded documents.

0.11.0

• Improved: the Signature field (Business Identity) is now a multi-line text box — add a sign-off, business name, phone, and address on separate lines and the line breaks are kept.
• Fixed: the configured signature is now actually included in every AI reply. Previously it only worked if you hand-edited the {signature} placeholder into your prompt template.

0.10.1

• Fixed: AI replies now open with a greeting addressing the visitor by first name and close with a business-name sign-off. Replies had lost their email shape after the visitor's message was routed into the chat user role.

0.10.0

• Added: a data-use disclosure with Privacy and Terms links on the account-connect step (onboarding and setup), so it's clear at that point that form submissions are sent to OpenAI and the Inquix API.
• Added: suggested privacy-policy text under Settings → Privacy → Policy Guide, to help you document Inquix AI's data handling in your site's privacy policy.

0.9.0

• Improved: "Manage subscription" now opens the Stripe billing portal directly instead of routing through the upgrade page, and active subscribers see Manage Subscription at the top of the Upgrade page.
• Added: quick "Settings" and "Upgrade to Pro" / "Manage Subscription" links on the WordPress Plugins page, next to Activate/Deactivate.

0.8.15

• Fixed: AI reply no longer fails to send when the visitor's email address matches your "reply-from" address and "Copy reply to from email" is enabled. Previously the email was rejected as a duplicate recipient; the copy is now skipped (you still receive the reply as the direct recipient).

0.8.14

• Fixed: email fields (account, reply-from, escalation) now validate the address before saving. Invalid input is blocked with an inline error instead of being silently discarded; empty stays allowed (falls back to the default). Enforced both in the browser and on the server.

0.8.13

• Fixed: source/manual installs now default to the production Inquix API instead of a development endpoint. Official builds were already correct; this only affects plugins installed directly from source.

0.8.12

• Fixed: the OpenAI API Key step in onboarding now requires a successful Test Connection before you can continue. Previously the step accepted any input and the validation wall only appeared at the final Finish Setup step, forcing you to backtrack.
• Fixed: clicking Test Connection without changing the masked placeholder (shown when a key is already stored) no longer overwrites the real stored key with the placeholder string.
• Fixed: settings inputs across onboarding and AI Agent Settings (company name, signature, sender details, escalation keywords, OpenAI key, etc.) no longer trigger save prompts from password managers like Bitwarden, 1Password, and LastPass.

0.8.11

• Fixed: AI replies to Contact Form 7 submissions now actually respond to the visitor's question. Previously the visitor's message was only embedded inside the system prompt while a generic placeholder was sent as the user message — the model would write generic replies that appeared to ignore the template.
• Fixed: "Answer only from Knowledge Base" toggle now actually controls behaviour. The strict knowledge-base instruction has been removed from the default prompt template and is applied only when the toggle is on and a Knowledge Base is configured.
• Changed: "Answer only from Knowledge Base" now defaults to ON for new installs. With a Knowledge Base configured, the assistant stays inside its content. You can turn the toggle off in AI Agent Settings → Knowledge Base to let the assistant speak generally outside the KB.
• Added: when no Knowledge Base is configured, the AI now uses only the business identity you provided (company name, industry, signature) and politely offers to connect the visitor with a team member for any specific question it has not been given facts for. The AI no longer invents hours, prices, products, policies, or addresses on empty-KB installs.

0.8.9

• Fixed: after re-onboarding (i.e. running Disconnect or Delete Site Data and then completing onboarding again), the system prompt template was left empty. It is now restored to the plugin default on onboarding finish if the user has not customised it.

0.8.8

• Fixed: rare backend rate-limit (429) during email confirmation polling now shows the same friendly wait-or-contact message as the connect step, instead of leaking the raw error string.

0.8.7

• Fixed: the yellow reminder shown on the Plugins screen before deleting Inquix AI now uses WordPress-native spacing, matching the visual treatment of other plugins' update-available notices.

0.8.6

• Maintenance: CI cleanup after renaming the plugin's GitHub repository to match the plugin slug — the WP.org Plugin Check job no longer needs its slug workaround. No functional change.

0.8.5

• Fixed: on the Upgrade to Pro page itself, the redundant "Upgrade to Pro" button no longer appears in the page header (the Stripe checkout button at the bottom remains). The header button still shows on every other admin page for free-plan users.

0.8.4

• Improved: the Inquix admin menu is reordered to put daily-use surfaces first — Overview, Inbox, AI Agent Settings, Logs, then Setup, Diagnostics, Upgrade to Pro.

0.8.3

• Fixed: in the guided onboarding, the Save & Continue button is now aligned with the inputs and other buttons in each section (previously it was nudged ~12px to the right by an empty feedback span).

0.8.2

• Improved: save buttons across all admin pages now use a consistent green to distinguish "save / confirm" from "action / navigation" — matching the existing green used for "Replies ON" and connected-state checkmarks on the Overview.

0.8.1

• Fixed: the onboarding page now opens at the top — showing the welcome and "What you'll need" overview — instead of jumping straight to step 1.

0.8.0

• New: the guided onboarding now opens with a "What you'll need" overview — a valid email, an OpenAI API key (with a link to get one), and a recommendation to prepare a Knowledge Base for more accurate replies.

0.7.1

• Improved: the reminder shown on the Plugins screen before deleting Inquix AI now explains that deleting the plugin removes only local settings, and points you to Delete Site Data (Inquix AI → Setup) to also remove your account and site data from Inquix servers.

0.7.0

• New: an Approval Mode toggle in the guided onboarding (Email Delivery step) — opt in during setup to hold AI replies in the Inbox for review before they're sent, instead of sending automatically. Off by default.

0.6.0

• New: the Knowledge Base step in the guided onboarding (§6) is now fully interactive — upload PDF/DOCX, add FAQ/Policy/Facts, view, delete, and the "Answer ONLY using Knowledge Base" toggle, all without leaving onboarding. Still optional/skippable.

0.5.2

• Maintenance: refreshed WordPress compatibility (tested up to 7.0). No functional change.

0.5.1

• Maintenance: addressed WordPress.org Plugin Check findings — added missing i18n translators: comments, ordered placeholder positions, escaped admin output, applied wp_unslash() to $_POST / $_FILES reads, gated debug error_log() calls behind WP_DEBUG, removed the unused Domain Path plugin header and the redundant load_plugin_textdomain() call (WP.org auto-loads since 4.6), aligned readme.txt title to the plugin header, and trimmed tags to 5. No functional change.

0.5.0

• New: guided onboarding page (INQ-43) — on a fresh install a single progressively-gated page walks through account connection, OpenAI key, email delivery, business identity, form selection, knowledge base (informational), sender details, and escalation; the full menu unlocks once onboarding completes.

0.4.5

• Fixed: Clearer message when the backend is rate-limiting registration attempts (shows a wait/contact hint instead of a generic error).

0.4.4

• Maintenance: removed unused internal code left over after 0.4.3. No functional change.

0.4.3

• Fixed: Disconnect now removes the site from the Inquix backend instead of only unlinking locally (no more orphaned records).
• Fixed: Disconnect and Delete Site Data now clear all plugin settings (knowledge base, prompts, sender details, escalation rules, logs, etc.) — the site returns to a true fresh-install state. Previously many settings survived.

0.4.2

• Fixed: corrected the Pro price to €29/month and the free-tier quota to 15 AI replies/month in the plugin description (both were previously misstated).

0.4.1

• Maintenance: removed unused legacy code from the plugin package (no functional change).
• Added a Third-Party Services disclosure to the plugin description.
• Updated WordPress compatibility (tested up to 6.9).

0.4.0

• AI Agent Settings → Business Identity now mirrors the saved Industry to the Inquix backend so it surfaces in the admin panel. Best-effort: if the API call fails, the local save still succeeds.

0.3.1

• Fixed: selecting Construction & Craftsmen in AI Agent Settings → Business Identity now saves correctly. The save handler had a hardcoded allowlist that omitted the new slug introduced in 0.3.0, so the value was silently dropped.

0.3.0

• Added a new Construction & Craftsmen industry option (renovation, carpentry, custom builds) with its own tone/vocabulary nudge — for project-scoped work that needs a site visit before pricing, distinct from on-call Trades & Home Services.
• Expanded Professional Services examples to include marketing, design, bookkeeping, and freelance.

0.2.1

• Knowledge Base: uploading a file or adding a text entry whose name matches an existing entry now prompts to replace instead of silently creating a duplicate. Match is case-insensitive and cross-type (a PDF "Refund Policy" matches a text entry "refund policy").

0.2.0

• Expanded Industry list in AI Agent Settings from 5 to 12 options (E-commerce, Restaurant, Hospitality, Booking, Health & Wellness, Professional Services, Support, Trades, Real Estate, Education, Nonprofit, Other).
• AI replies now include a per-industry tone/vocabulary nudge in the system prompt for the 11 named industries.
• Existing sites are unaffected — saved industry values continue to work.

0.1.1

• Removed the Prompt Optimizer tool from AI Agent Settings → Advanced/Expert Mode.

0.1.0

• First release from the dedicated inquix-wp repository.
• Version reset from 1.11.25 to 0.1.0 as the plugin moves toward WordPress.org submission at 1.0.0.
• No functional changes from 1.11.25 — pre-1.0 versioning baseline.
• Full historical changelog (1.0.0 – 1.11.25) preserved in git history.
