The tools
15 tools across six categories
Built the way we build for clients — tested, accessible, and honest about their own limitations.
SEO tools, done for you in your browser
The tools you reach for when a page is written but not yet ready to ship — structured data that validates, campaign links that stay consistent, and a speed test that returns a verdict instead of a bare score.

Latest release
40 free 80s Bollywood photo prompts, now with real examples
The viral retro-photo trend, written as copy-and-paste prompts for ChatGPT and the Gemini app — men, women, couples, families, friend groups and kids, each one shown against a real generated photo instead of a description alone.
- Every prompt ships with a real example photo, not a mockup
- 40 of 40 pair with a video prompt (Veo, Kling, Runway) that animates that exact photo
- Zero fill-in variables — copy the whole prompt and paste it straight into ChatGPT or Gemini
Free prompt library
1,211 prompts for the AI tools you already use
ChatGPT, Claude, Cursor, Midjourney, Veo and 47 more categories — organized by tool, shown in full, no account anywhere. Not another undated prompt dump:
- Every prompt is version-stamped against the tool it was tested on
- Every prompt explains why it works, not just what to paste
- Stale prompts get flagged, not left to quietly rot

Free agent skills library
10,000 best AI agent skills
We indexed 50,456+ real, public `SKILL.md` files from the open skills.sh registry and kept the most-installed — organized by the task you're doing, not by which AI tool you use. Works natively with Claude Code, Cursor, Codex CLI, and Copilot:
- Every skill is a real file from a public repo, never invented
- Copy as-is, or export as AGENTS.md, .cursorrules, or Copilot instructions
- Organized by task — testing, debugging, deployment — not by AI brand

Can AI search engines even see your site?
ChatGPT, Claude, Perplexity and Google's AI answers are becoming a real acquisition channel — and many sites block their crawlers without knowing it. Run the check: one URL in, a 0–100 visibility score and the exact fixes out.
CHECK YOUR AI VISIBILITYPrivacy as a feature
Your files never leave your browser
Most of these tools do their work with your browser's own capabilities — Canvas, native parsers, Web APIs. No upload step, no server copy. Open your network panel and watch it stay empty while you work.
13/ 15 tools
run entirely inside your browser — no upload, no server copy, nothing to intercept. The two diagnostics that must touch the network (the speed test and the AI visibility checker) send only the URL you type, never your content.
No accounts, ever
Nothing to sign up for means no password of yours to hold and no profile of you to build.
No result gating
The full result renders first. Any offer to email something comes after you already have it.
Faster by design
Skipping the upload is not just private — it is why these tools feel instant.
The maths is shown
Every calculator and checker explains its formula so you can verify it, not trust it.

Questions
The honest answers
Are these tools really free?
Yes — no trial, no quota, no premium tier. Most of them run entirely in your browser, so they cost us nothing per use, and there is nothing to recover.
Do I need an account?
No. There is nothing to sign up for anywhere on this site. Results are yours to copy or download the moment they appear.
Is my data uploaded anywhere?
For 13 of the 15 tools, no — files and text are processed inside your own tab and are gone when you close it. The two diagnostics that must fetch a URL (the speed test and the AI visibility checker) send only that URL, never your files. The privacy page lists exactly which is which.
Are the prompts and skills free too?
Completely. Every prompt is shown in full on its own page — no teaser, no unlock, no email gate — and every skill is a real public SKILL.md you can copy as-is or export for your agent. The same zero-signup rule covers all three catalogues.
What is the MCP server?
A free, public endpoint that lets AI agents — Claude, Cursor, ChatGPT or any MCP client — call these tools directly: generate schema markup, build UTM links, search the prompt and skill libraries, all mid-conversation. One config line to connect, no auth. Setup instructions live on the MCP page.
Why did an agency build free tools?
These are the utilities our own delivery team uses on client work. Publishing them costs us almost nothing, and when you eventually need a team rather than a tool, you will already know who we are.
Can I request a tool?
Yes — tell us what you need through the contact details on scult.in. The catalogue is deliberately small and curated, so we add tools when they are genuinely useful, not to inflate a number.
Missing something?
Need a tool we don't have?
Tell us what you're trying to do. We read every request, and it is how this catalogue grows — deliberately, not by inflating a number.
