Tell it your website or a topic, and it shows you exactly what to write to rank on Google, with real search data behind every recommendation, then writes the first draft for you.

What you are buying

A finished, deployed SaaS product in the AI content space. Not a prototype, not a GPT wrapper with a landing page: a complete four-step workflow backed by professional-grade keyword data, with billing, usage metering, an admin panel and an automated test suite already in place.

The hard engineering is done. What is left is marketing, which is exactly the part a buyer with an audience can do far better than a developer.

The product

A guided workflow that takes a user from "I need traffic" to a publish-ready article:

1. Choose a source. Analyse your own site (what am I close to ranking for?), a competitor's (what do they own that I don't?), or a bare topic.

2. Prioritise. Real search volume, keyword difficulty, CPC and buyer intent pulled live from a commercial search data API. Opportunities are scored and labelled in plain English: Quick Wins, Top Opportunities, Growth Plays. Google SERP features (AI Overviews, local packs, featured snippets) are shown with explanations of what each means for your chances.

3. Shape the brief. AI generates five distinct angles per keyword. The user sets tone of voice (7 presets plus free-text brand guidance), target audience, exact word count, and British or American spelling.

4. Create drafts. Full articles, 1,500 to 2,500 words, formatted with SEO meta tags, landing in a content library with a draft, review, published workflow and one-click export to WordPress (Gutenberg blocks), Webflow, Markdown, HTML or plain text.

Drafts are fully editable in-app and save back with live word and character counts against SEO limits.

Monetisation: built, tested, subscription-ready

Live today, one-off credit packs via Stripe Checkout:

| Pack | Credits | Price |

| Starter | 100 | £9 |
| Growth | 500 | £39 |
| Pro | 2,000 | £129 |
| Enterprise | 5,000 | £299 |

Credits are consumed per action (article 5, site analysis 2, keyword search 1), charged before the work runs and automatically refunded if it fails. New signups get 100 free credits, roughly 20 articles, as a frictionless trial.

Subscription-ready: the full tier structure is already built and enforced in code. Free, Starter, Pro and Enterprise each have their own monthly credit allowance and daily fair-use caps (5, 20, 50 and 200 articles per day), plus automated daily and monthly counter resets on a scheduler. Stripe is integrated and the webhook is hardened. Converting the existing Checkout call from one-off payments to recurring subscriptions is a small, well-understood change. The metering that makes a subscription work is the part that is already done.

The margin is the story. An article costs roughly 0.3p to produce and sells for 5 credits (about 45p at the entry pack), around a 99% gross margin. There is meaningful room to cut prices for competitive advantage and still run profitably.

Technical condition

This is not a codebase you will be afraid to open:

  • Laravel 10, PHP 8.1+, MySQL. A conventional, well-documented stack any PHP developer can pick up.
  • 46 automated tests, all passing, covering payment webhooks, tenant isolation, usage enforcement, auth and content generation.
  • Hardened Stripe integration. Signature-verified webhook that fails closed, with atomic transaction claims so a customer can never be double-credited by a race between the webhook and the success page.
  • Proper multi-tenancy. Every query scoped per user, with tests proving one account cannot see another's data.
  • Admin panel. User management, credit grants and deductions with a full audit trail, revenue and usage dashboards.
  • Password reset, email notifications on signup, and a deployment health-check command that validates the entire production configuration.
  • One-command deployment with documented cPanel setup, plus git hooks that build frontend assets automatically.

Why now

AI content tools are a proven, actively-spending market. Surfer, Frase and NeuronWriter all charge £40 to £100 per month for overlapping functionality. This product's differentiator is that recommendations are grounded in real search data, not AI guesswork, and the workflow is opinionated enough for non-experts.

Honest context: the category is competitive, and Google's AI Overviews are reshaping search traffic. This product acknowledges that directly. It flags AI Overview presence per keyword and explains the implications, which most competitors do not.

What is not done, stated plainly

I would rather you hear this from the listing than find it in diligence:

  • Zero revenue and zero users. You are buying a finished product and its economics, not a customer base.
  • Recurring billing is not yet switched on. The tiers and metering are built, the Stripe subscription mode is not.
  • Publishing is export, not one-click. The WordPress export produces perfect Gutenberg blocks, but the user still pastes. A direct WordPress integration is the single highest-value next feature.
  • No email verification on signup yet. Daily free-tier caps limit abuse in the meantime.
  • No rank tracking. The product finds opportunities and writes content but does not yet report whether it worked.

Each of these is a roadmap item with clear commercial value, not a defect.

Ideal buyer

  • SEO or marketing agencies. Use it internally to cut content production cost, resell it to your existing client base, or both. Distribution is the missing piece, and you already have it.
  • Existing SaaS operators. A complete product to bolt onto an audience you have already built.
  • Technical founders. Skip 3 to 6 months of build and start on distribution tomorrow.

Included in the sale

  • Full source code and complete git history
  • The domain name
  • Production deployment scripts and documentation
  • Database schema and migrations
  • 30 days of email support for handover

Integrations run on the buyer's own AI, search data and Stripe accounts. All are standard, self-serve signups.
