Every AI tool answers better when you tell it how. A prompt that makes Claude stop apologising, a rule that keeps Cursor inside your conventions, a system message that gets Gemini to write Persian a native reader would actually write — those exist, scattered across hundreds of repositories, and finding the right one when you need it is the whole problem.

Skills AI collects 5,402 of them for 102 tools, sorts them into 12 categories, and puts them one search away. The entire catalogue is inside the app: it opens on a train, in a tunnel, on a plane, with no signal and no account.

What it does

• Works with no connection — The whole catalogue — 5,402 skills, their full text, and the search index — ships inside the app as a 17 MB SQLite database. Nothing is fetched to read it.
  
• Search that understands the language you type in — Full-text search across every title and body, with Persian and Arabic folded together: a query typed with Arabic yeh finds text written with Persian yeh, and three sets of digits count as one.
  
• Copy, do not retype — Every skill carries its exact text, an install procedure for the tool it belongs to, and a copy button on each part.
  
• Did it actually work? — One tap after you use a skill says whether it worked, partly worked, or did not — for the model you used. Skills are ranked by that, counted per person, so answering more often moves nothing.
  
• A community, without a scoreboard — Publish your own skills, follow the people whose work keeps helping you, and see on a skill itself which of them tried it. There is no public follower ranking and no endpoint that lists the graph.
  
• Eight languages, four of them right-to-left — English, Persian, Arabic, Turkish, Hindi, Spanish, German and French — the interface, the numerals, the dates and the direction of the layout.
