The open-source ChatGPT alternative that stays on your machine. Desktop-first, privacy-first, and fully offline-capable. Maintained by Jan HQ (janhq on GitHub) with a community of tens of thousands of contributors.
System Verdict
Pick Jan.ai if open-source matters to you and you want a desktop ChatGPT replacement. The app is fully MIT-licensed on GitHub, runs 100% offline, and handles local open-weight models (Llama, Qwen, Mistral, Gemma) with a polished chat UI. Also connects to cloud APIs (OpenAI, Claude, Gemini) if you want a unified chat client for both.
Skip it if you want the largest model catalog or server deployment. LM Studio has a deeper model browser; Ollama is better for CLI or Docker/server use. For raw convenience + feature depth, those alternatives still edge Jan.
Pricing is simple: $0 for everything that matters. No subscription tiers, no feature walls. The only paid item is a $24 one-time Mac voice-to-text pack. Commercial use is permitted under the open-source license.

When to pick Jan.ai
- Open-source purists. You want the app itself to be open source, not just the models it runs. Jan is auditable end to end; LM Studio is not.
- Desktop-first privacy workflows. Local models + local data = nothing leaves your machine. Safe for confidential work.
- Switching between local and cloud. The same UI handles Llama 4 local and OpenAI frontier models cloud. Useful when you want local for drafting and cloud for polishing.
- Mac-friendly voice input. The optional $24 voice-to-text pack is a one-time buy for fluent voice-to-text on Apple Silicon.
When to pick something else
- Maximum model catalog: LM Studio has deeper integration with Hugging Face’s GGUF catalog.
- CLI + server use: Ollama is the better fit for scripting and headless deployments.
- Zero-effort onboarding: LM Studio’s model browser is slightly easier for complete beginners.
- Cloud-only chat users: If you never plan to run local models, TypingMind or ChatGPT give you more cloud-specific features.
Pricing
Jan.ai is fundamentally free.
| Item | Price |

Failure modes
- Hardware limits. Like all local-AI tools, a weak GPU or low RAM caps what you can run. A 16GB laptop tops out around 13B-parameter models at Q4 quantization.
- Smaller community than LM Studio or Ollama. Fewer YouTube tutorials, fewer Stack Overflow answers. Use the Discord or GitHub issues for support.
- Model catalog is via GGUF and remote APIs. Same underlying formats as LM Studio; differences are UI and extension ecosystem.
- Not a great fit for production use. Personal desktop app, not a server platform. For team or production deployments use AnythingLLM or a hosted open-weight provider.
- Voice pack is Mac-only. Windows and Linux users don’t have an equivalent paid extension yet.

FAQ
Is Jan.ai really free? Yes. The desktop app, all core features, and model support are $0 forever. Only the optional Mac voice-to-text pack costs $24 one-time.
Does Jan.ai send any data to the internet? In local-only mode, no. Everything stays on your device. If you configure cloud API connections (OpenAI, Claude, Gemini), those calls go to the respective providers under their normal data policies.
How does Jan.ai compare to Ollama? Jan is a full desktop app with a chat UI. Ollama is a runtime + HTTP server primarily driven via CLI. Jan is friendlier for non-technical users; Ollama is better for developers and servers. Jan can use Ollama as a backend if you want both.
Can I use Jan.ai commercially? Yes. The open-source license permits commercial use. No per-seat or enterprise-tier restrictions.
