# I'm Not a Robot
**English** · Русский
**A free-first captcha solver for macOS.** A drop-in replacement for the 2Captcha / RuCaptcha API that tries free solvers first — a local model, then any vision model you choose, then an invisible browser — and pays human workers only when nothing else worked. Comes with a menu bar app and an MCP server for AI agents.
## Why
- **Any model, free if you like.** Bring a key of any vision model — GPT, Claude, Gemini, Qwen, DeepSeek, Grok, OpenRouter, a reseller or a local model via Ollama. The best one for captchas switches on by itself. With a free-tier key or a local model most captchas never reach the paid step.
- **No code changes.** Any program that speaks the 2Captcha or RuCaptcha API works after changing one address.
- **A ladder, not a single bet.** Local model → vision model → backup vision model → browser → humans. A step that is unsure, wrong or silent hands the captcha to the next one.
- **It learns from mistakes.** Report a wrong answer and the step is no longer used on that picture; a step that keeps failing on a kind of captcha is skipped for that kind; complaints about human answers go to the service, which refunds them.
- **You see everything.** Journal of every captcha with the picture, the answer and the path it took; daily money limits; side-by-side model comparison.
- **Agents welcome.** An MCP server lets Claude, Cursor and other agents solve captchas through the app.
## Quick start
1. Download `ImNotARobot.dmg` from Releases and move the app to Applications. It is not signed by Apple yet: if macOS blocks the first launch, press **Open Anyway** in System Settings → Privacy & Security.
2. Paste a key of any vision model into **Keys and models**: the provider is detected and the best model for captchas switches on by itself. No key yet? Gemini has a free tier at aistudio.google.com/apikey.
3. In your program, change the captcha service address to `http://127.0.0.1:8765` and the API key to the access key from **Connection**.
Optional: add a RuCaptcha or 2Captcha key as the last, paid step.
## How it works
| Step | Solves | Cost | Time |
|---|---|---|---|
| 1. Local model (ddddocr, piece matching) | text, sliders | free | milliseconds |
| 2. Vision model (any: GPT, Claude, Gemini, Qwen, DeepSeek, Grok, local) | text, picture grids, clicks | free tier or cents | 3–8 s |
| 3. Backup vision model (another model or the same with thinking) | what step 2 was unsure about | free tier or cents | 10–50 s |
| 4. Browser (invisible Chrome) | reCAPTCHA v2/v3, hCaptcha, Turnstile | free | 3 s – 2 min |
| 5. RuCaptcha / 2Captcha | anything | paid | 10–60 s |
