Jan

Open-source offline AI assistant with local models, agents, and total privacy.

73/100Safe BetFreeFree

Jan is the definitive offline AI app for developers who want privacy and customization without paying a monthly fee. Its agent features, local API, and steady stream of updates make it a strong choice, but it's not turnkey—you'll need to manage models and infrastructure yourself. Skip it if you want a polished, zero-setup ChatGPT experience.

Skip it if

Skip Jan if you want a polished, zero-setup ChatGPT experience or lack the hardware (no GPU or under 8GB RAM) to run local models efficiently—it expects tinkering and technical expertise.

The 30-second take
Biggest gripe

Jan is free and open-source, but you'll need to provide your own hardware—a capable GPU or at least 8GB of RAM—to run large models at usable speeds.

Price reality

Jan is completely free and open-source—no subscription, no per-seat fees, and no usage caps. This makes it ideal for individuals and teams who want to avoid monthly costs of cloud AI assistants like ChatGPT Plus ($20/mo) or Claude Pro. However, you pay with your own hardware and time: you'll need a decent GPU or at least 8GB of RAM, and you'll manage models and infrastructure yourself. For privacy-focused developers and researchers, the cost savings and data control are unmatched.

About Jan

FreeIntermediateAPI availableDesktop · CLI · API

Jan is a free, open-source AI platform that runs entirely on your machine, giving you ChatGPT-like capabilities without the trade-offs of cloud dependence or data leaving your computer. With over 6.4 million downloads and 44.2K GitHub stars, it's a community-driven project built for privacy-conscious users, developers, and researchers who want full control over their AI. Jan supports open models from HuggingFace (Llama, Mistral, Qwen, DeepSeek, Gemma, Kimi) and also lets you plug in online providers like OpenAI, Anthropic, and Google when you need a hybrid setup. Its modular architecture includes the Jan Desktop app for macOS, Windows, and Linux, plus a CLI, a local API server compatible with OpenAI's spec, and the separately distributed Jan Agent for running on your own VM or container. The latest updates show steady evolution: v0.8.4 (July 2026) adds native web search and web fetch tools, per-model chat templates, a token counter, and a backend-managed settings store. v0.8.3 introduced message branching with version history, HTML/SVG artifact previews, and video input for local vision models. v0.8.2 brought AMD ROCm/HIP support on Linux and resumable downloads, while earlier versions added Anthropic-compatible providers, multi-token prediction, and inline MCP tool approval with citation cards. These features make Jan not just a chat client but a capable local AI workstation. What sets Jan apart is its agent ecosystem: agents can browse files, manage calendars, and send messages via Slack, Discord, or WhatsApp—all controlled locally. The memory feature is coming soon, promising context that carries over across sessions. Compared to ChatGPT or Claude, Jan gives you absolute data sovereignty, but it demands capable hardware (a decent GPU or at least 8GB of RAM) and a willingness to tinker. It's a direct alternative to Ollama or LM Studio, but more ambitious in scope, blending local inference with agent workflows and a pluggable backend.

Behind the Verdict

Jan has carved out a unique niche as a fully open-source, offline-first AI assistant. The project's latest versions (through v0.8.4, July 2026) show a commitment to serious engineering: native web search tools, message branching with version history, AMD ROCm/HIP support on Linux, and a local API server compatible with OpenAI's spec. For developers, this means you can run a private ChatGPT-like experience with the ability to swap models freely and even build custom agents that automate workflows (file browsing, calendar management, Slack/Discord/WhatsApp messaging). The agent ecosystem, Jan Agent, is distributed separately and can be run on your own VM or container, giving enterprise teams a path to decentralized AI. Where Jan shines: absolute data control, zero subscription costs, and a thriving open-source community (44.2K+ GitHub stars). It's ideal for privacy-sensitive professionals (lawyers, doctors, researchers) and developers who want to prototype against an OpenAI-compatible local endpoint. The recent addition of multi-token prediction and inline MCP approval shows the team is focused on performance and security. Where Jan falls short: it's not a polished consumer app. Setup requires technical expertise—you'll need to manage model downloads, hardware specs, and sometimes compile or configure backends. The 'Memory' feature is still 'Coming Soon,' so long-term context is not yet available. Artifact previews are limited to HTML/SVG. Performance on low-end hardware (no GPU or under 8GB RAM) will be frustrating. Also, there's no centralized billing or enterprise support, so large organizations may find it lacking. In short, Jan is a powerful tool for tinkerers and privacy advocates, but it's not a drop-in replacement for ChatGPT for the average user. It's a legitimate alternative to Ollama or LM Studio, with more ambition and a larger feature set, but it requires more effort to set up and maintain.

Limitations

  • Jan is an open-source AI assistant that can run offline with local models, so performance depends on your own hardware (RAM/GPU).
  • The Memory feature is listed as 'Coming Soon' and is not yet available.
  • Artifact previews are currently limited to HTML and SVG formats.
  • Setup may require technical expertise to install and manage models.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • Jan is free and open-source, but you'll need to provide your own hardware—a capable GPU or at least 8GB of RAM—to run large models at usable speeds.
  • Downloading large models (several GB each) from HuggingFace may consume significant bandwidth and storage, though downloads are resumable from v0.8.2.
  • If you use online providers (OpenAI, Anthropic, etc.) through Jan, you'll pay their usage fees separately—Jan itself doesn't bundle cloud model costs.
  • Running multiple agents or heavy local inference can increase electricity costs and system load, especially on laptops without proper cooling.

Where the pricing makes sense

The company stage and team size where Jan's pricing actually pencils out — and where peers do it cheaper.

Jan is completely free and open-source—no subscription, no per-seat fees, and no usage caps. This makes it ideal for individuals and teams who want to avoid monthly costs of cloud AI assistants like ChatGPT Plus ($20/mo) or Claude Pro. However, you pay with your own hardware and time: you'll need a decent GPU or at least 8GB of RAM, and you'll manage models and infrastructure yourself. For privacy-focused developers and researchers, the cost savings and data control are unmatched.

Setup time & first value

How long it actually takes to get something useful out of Jan — broken out by persona, not the marketing-page minute.

For a developer familiar with command-line tools, you can install Jan Desktop and download a small model (e.g., 7B) within 15 minutes. For less technical users, expect 30-60 minutes to get a large model running and configure settings. Running agents or the CLI may take another hour to set up. The exact time depends on your hardware and internet speed.

Switching to or from Jan

How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.

Migrating in
  • From Ollama: Export your models and use Jan's HuggingFace integration to pull the same or different local models. Jan acts as a full UI with agent capabilities on top of local inference.
  • From LM Studio: You can import your existing GGUF models into Jan or point it to your local model folder. The transition is straightforward if you're comfortable with file paths.
Migrating out
  • To Ollama: If you prefer a lighter CLI-only tool, you can export your models and scripts, though Jan's agent features won't carry over.
  • To ChatGPT/Claude: If you need managed cloud AI with low setup, you can export your chat history from Jan (if available) and manually replicate workflows, but you'll lose offline/local control.
