## Jan

Jan is a desktop application that positions itself as an open replacement for ChatGPT, with the key difference that inference happens on hardware you control. After installing the app you pick a model, and Jan downloads and runs it locally, so prompts, chat history, and files stay on your machine rather than on someone else's server. For heavier workloads you can connect an OpenAI, Anthropic, Gemini, or Mistral key and route requests to the cloud while keeping the same chat interface and local history.

The project is developed in the open by Menlo Research and has accumulated tens of thousands of GitHub stars along with millions of downloads. It exposes OpenAI-compatible local endpoints, which means existing tooling and SDKs can point at Jan instead of a hosted service, and it supports custom assistants with their own instructions and model choices. Recent releases have added an agent surface alongside the classic desktop chat, and a memory feature is announced as coming to carry context and preferences between sessions.

Because it is open source, Jan can be audited, self-built, and extended, and there is no paid tier gating the desktop client. The practical tradeoff is that local model quality and speed depend entirely on your own GPU or CPU, so lighter machines will favor smaller quantized models while cloud keys remain the escape hatch for harder tasks.

**Pricing & Plans:** Jan is free and open source, with no paid tier for the desktop app. Costs only appear if you optionally connect your own paid cloud API keys for providers such as OpenAI or Anthropic.

- **Local-first inference:** Download and run open models such as Llama, Mistral, Qwen, Gemma, and DeepSeek directly on your own machine, with chat data kept on device.
- **Bring your own cloud models:** Optionally connect API keys for OpenAI, Anthropic, Gemini, Mistral, and other providers to route requests to frontier models from the same interface.
- **OpenAI-compatible local API:** Jan exposes a local server endpoint that follows the OpenAI API shape, so existing SDKs and tools can talk to your local models without code changes.
- **Custom assistants:** Create assistants with their own system instructions, model selection, and parameters, then reuse them across conversations.
- **Open source and extensible:** The full desktop client and agent code are public on GitHub, so you can audit behavior, build your own version, and contribute improvements.

**Strengths:** Completely free and open source, with no account required to run local models; Conversation data stays on your device by default; Works across macOS, Windows, and Linux with an OpenAI-compatible local endpoint; Optional cloud key support lets you mix local and frontier models in one app

**Limitations:** Local model quality and speed are capped by your own hardware; Very large models may need substantial RAM or VRAM to be practical; Some cloud-connected and memory features are newer or still rolling out

## Msty

Msty began as a desktop application for running and comparing AI models locally, and has since grown into a four-part ecosystem covering individual, team, and organizational use. The core appeal has stayed constant: use the models you want, keep your data on your own terms, and avoid being locked to a single vendor's chat interface.

The products map to distinct jobs. Msty Studio is the private workspace itself — chat, knowledge organization, media creation, and prompt reuse in one place, available as a download. Msty Go adds bounded agents that execute scoped tasks with each step reviewable from desktop or mobile. Msty Nexus is a central model gateway for managing runtimes, providers, credentials, policies, and usage. Msty Stack packages approved sources into versioned Knowledge Stacks that approved AI apps can retrieve, so organizational context stays governed rather than scattered.

Governance is a deliberate focus rather than an afterthought. The company publishes access controls, model and feature controls, administrative audit logs, customer-controlled storage, zero product telemetry, and DPA availability. It is candid that formal SOC 2 and ISO 27001 certification were not yet complete at the time of review, and instead points to a security brief outlining what is available today — a transparency that suits regulated teams evaluating the platform.

**Pricing & Plans:** Msty offers a free starting point, a paid Msty Studio license for individuals, and enterprise deployments scoped through conversation with the team. Pricing details are published on the site's pricing page.

- **Private AI workspace:** Chat with models, organize knowledge, create media, and reuse prompts inside one privacy-first environment that runs on your own machine.
- **Bounded agents:** Run scoped agents on real tasks, review each step, and keep control from desktop or mobile rather than delegating a whole workflow blind.
- **Model gateway and controls:** Nexus acts as a central hub to manage runtimes, providers, API keys, policies, app tokens, and usage across an organization.
- **Governed knowledge stacks:** Package approved sources into versioned Knowledge Stacks that approved AI apps can retrieve and reuse, keeping context governed.
- **Split chats and prompt library:** Split chats let you send the same prompt to multiple models side by side and compare answers without leaving the workspace.

**Strengths:** Model-agnostic by design, so you are not locked into one provider's ecosystem; Local-first architecture supports offline use and keeps sensitive context on your own machine; Product range scales from a solo workspace to governed team deployments with SSO and audit logs; Publishes a candid security position instead of overstating certification status

**Limitations:** Formal SOC 2 and ISO 27001 certification were still in progress at the time of review; The ecosystem spans several products, so choosing the right starting point takes some navigation; Enterprise governance features such as Nexus and Stack add complexity that individual users do not need
