Built by Maruf
One builder. Five live tools.
No accounts required.
Prompt Intelligence Studio is one of an ongoing set of independent products — each one solving a specific, real problem, each one running as much as possible in your browser instead of on a server that has to be trusted, paid for, and kept online forever.
The projects
What's live right now
Prompt Intelligence Studio
You're hereThe quality-control platform for AI prompts. Score a prompt across seven categories and get a rewrite, free with Local Rules in your browser, or bring your own provider key for AI-generated analysis.
TidyText AI
A browser-based writing and translation tool. Bring your own Gemini, OpenAI or Anthropic key, edit across 44 languages, and see every prompt it uses — no subscription, no hidden rewriting of your voice.
Visit TidyText AIFreeBarcodeTools
Free FNSKU, Code-128, EAN-13, UPC-A and QR barcode generation for Amazon FBA sellers, plus 2D box-content labels and batch CSV runs. Every label renders locally — nothing you type leaves your browser.
Visit FreeBarcodeToolsMizaanly
A free Islamic inheritance (Faraid) calculator for UK Muslim families, Sharia-compliant across all four madhabs, with an optional solicitor instruction letter for families who need one.
Visit MizaanlyRightToRentLog
A process log for England landlords running Right to Rent checks: a follow-up date calculator built on the statutory "later of" rule, and printable audit notes for the tenancy file. Not legal advice, and it says so.

The same four rules, every time
Your data stays yours
Local Rules, barcode rendering, inheritance shares, audit notes — the core calculation runs in your browser, not on a server collecting a database of your content.
Bring your own key, not our lock-in
Where a project uses AI, it uses the key you already have with the provider you already trust — never a shared platform key that limits, meters, or gates the free tier.
Free means free
No account wall in front of the core tool. If something genuinely costs money to produce — a solicitor letter, a premium export — that's the only thing you pay for.
Say what it isn't
A compliance log isn't legal advice. A deterministic score isn't a model's opinion. Every tool states its limits as plainly as its features.
