What You Can Do
File Management — Rename, sort, and clean up files across folders. Set up recurring tasks — daily inbox tidy, weekly download cleanup — and let Yak handle it on schedule.
Document & Spreadsheet Creation — Turn notes into formatted reports, spreadsheets with working formulas, and export-ready PDFs. AI generates the actual files — not just text you have to copy-paste and format yourself.
Data Analysis — Parse spreadsheets, CSVs, and documents on your machine. Spot trends, flag anomalies, and export reports — your data never leaves your device.
Research & Synthesis — Pull information from PDFs, local files, and the web. Summarize across sources, extract key points, and compile structured briefs — ready for review, not raw dumps.
Connect to 46+ services — Slack, Notion, GitHub, Figma, and more — through built-in connectors. Or add your own via MCP.

FAQ
Does my data leave my machine?
No. All files, conversations, and memory are stored locally on your device. The only data sent externally is your prompt text when using a cloud model — and even that goes directly to the model provider's API. No telemetry, no analytics, no cloud storage.
Is it free to use?
Yes. OpenYak includes 1M tokens per week on free models through OpenRouter at no cost. For premium models, you pay OpenRouter's prices with zero markup. You can also bring your own API key from 20+ providers, or run fully offline with Ollama for free.
Can I use it offline?
Yes. Install Ollama, download a model, and OpenYak works completely offline. No internet connection required. OpenYak auto-detects your local Ollama models and supports full tool-calling with them.
What models are supported?
100+ cloud models via OpenRouter, 20+ BYOK providers with direct API keys, and any model available through Ollama for local inference. New models are available as soon as they launch. See the Supported Providers section above.
How is this different from ChatGPT or Claude.ai?
OpenYak runs on your desktop with direct access to your local files and system. It can read, write, and organize your files, execute commands, and automate workflows — all while keeping your data on your machine. Web-based assistants cannot access your local filesystem.
