OpenYak: Free Open-Source AI That Runs on Your Machine (100+ Models)

Trending on Hacker News right now: an open-source desktop AI assistant that runs entirely locally. No cloud uploads. No telemetry. No vendor lock-in.

It's called OpenYak, and it might be the most interesting free AI tool I've seen this month.

Why This Matters

Most AI tools send your data to the cloud. All of it. Your conversations, your files, your prompts — sitting on someone else's server.

OpenYak flips that model. Everything stays on your machine. Your data never leaves your laptop. That's not a feature — it's the default.

What You Get for Free

The free tier is surprisingly generous:

• 1M tokens/week on free models
• 100+ AI models via OpenRouter — Claude, DeepSeek, Gemini, GPT-4.1, and more
• 20+ API providers — bring your own key from OpenAI, Anthropic, Google, Groq, Mistral, xAI, and Chinese providers
• ChatGPT subscription passthrough — already paying for ChatGPT? Connect it directly, zero extra cost
• Run locally via Ollama — completely offline if you want

That's not a "free trial." That's a real free tier with actual utility.

Built for Builders, Not Consumers

This isn't a chatbot. It's a productivity machine:

• File management — batch rename, sort, clean up files with change logs
• Data analysis — parse spreadsheets and CSVs locally, export reports
• Content drafting — turn notes into polished docs in your tone
• Team operations — merge PDFs, DOCX, CSVs into structured briefings
• IM integration — works with WhatsApp, Discord, Telegram, Slack, Signal, iMessage via OpenClaw
• Cron automations — schedule daily digests, weekly reports, automated cleanup

Seven agent modes. Long-term memory. MCP connectors for external tools. This thing was built to actually get work done.

The OpenClaw Connection

OpenYak integrates with OpenClaw for messaging — which means your AI assistant can receive and reply across all your channels from one place. If you're already in the OpenClaw ecosystem, this is a natural fit.

It's essentially a self-hosted version of what enterprise AI assistants charge $30-50/user/month for — except it's free and open source.

The Catch?

There isn't one. It's AGPL-3.0 licensed. You can inspect the code, contribute, or fork it. Premium models cost money through OpenRouter, but there's zero markup — you pay provider prices directly.

If you want to go fully offline, Ollama support means you can run local models with zero internet dependency.

Who Should Use This

Indie hackers who want AI without the subscriptions stacking up.

Privacy-conscious builders who don't trust cloud AI with client data.

Developers who want a local-first AI that integrates with their existing workflow.

Anyone tired of SaaS pricing — this replaces 3-4 separate AI subscriptions.
