Connected sessions across devices
Praex provides a browser chat, terminal CLI, desktop app, and Android app in closed testing. Its site describes continuing a task across screens with the same agent, session, and memory.
Praex
Praex is an AI copartner for browser chat, terminal coding, and desktop use, helping you work with code repositories and continue agent sessions across devices.
AI copartner for chat and terminal work
Praex is an AI copartner for chat and software work, available in a web browser and terminal, with desktop apps for macOS, Windows, and Linux. It runs hosted Praex models while also allowing users to connect supported external providers, local models, or OpenAI-compatible servers.
For development tasks, the Praex CLI can read repositories, edit files, run commands with permission, and search the live web. Sessions can be continued from the terminal in the web interface and, where available, on mobile devices.
Core capabilities
Permission-based coding agent
The CLI can inspect a repository, edit files, and run commands with user permission. Manual mode is the default, keeping the user involved in code-changing work.
Built-in web search
Praex can search the live web when a question requires current information; web search is also presented as a configurable preference in chat.
Hosted and bring-your-own-model options
Praex hosts and serves its own Velox II and Faber II models. It also supports external providers, local Ollama, and OpenAI-compatible endpoints for users who prefer their own models.
Project and session review
The desktop app provides projects, sessions, and a review of every change. The web interface can also surface terminal sessions through Remote Control.
Where Praex fits
Debugging and repairing a codebase
Use the CLI to investigate a failing deployment or test run: it can inspect project files, run commands, make edits with permission, and leave changes available for review.
Continuing terminal work from the browser
Start work in a terminal project, then use the web interface to view and continue the session through Remote Control when you are away from that machine.
Everyday questions and writing
Use browser chat for tasks such as drafting a message, explaining code, or thinking through a decision. Velox II is available to start without sign-up.
Working with an existing model setup
Connect an existing provider key, a local Ollama model, or an OpenAI-compatible server when a workflow requires a particular model or locally hosted endpoint.
Pros and Cons
Pros
- Velox II is available free in both the browser chat and terminal, with no card or API key required for the hosted model.
- The CLI asks before it reads, edits, or runs code, with manual mode enabled by default.
- Users can choose Praex-hosted models or connect external providers, local Ollama, and compatible custom endpoints.
- Terminal sessions can be accessed from the browser through Remote Control, supporting work that moves between devices.
Cons
- The Android app is in closed testing, and the site states that an iPhone app is not yet available.
- Desktop builds are not yet signed by Apple or Microsoft, so macOS and Windows installations may require an explicit operating-system override.
- Faber II is limited to the Pro plan, and Lucia II is described as opening soon.
FAQ
Can I try Praex without creating an account?
No. The web chat lets visitors start with Velox II without signing up; the site says Velox II is free every day in chat and the terminal.
Which platforms does Praex support?
The CLI is available for Linux and macOS. A desktop app is offered for macOS, Windows, and Linux; Windows CLI use is described as running under WSL. An Android app is in closed Google Play testing, while there is no iPhone app yet.
How does Praex handle code changes in the CLI?
The CLI can read repositories, edit files, and run commands after asking for permission. Manual mode is the default, so users can review and steer work.
Can I use my own model provider or API key?
Yes. Praex lists OpenAI, Anthropic, Google Gemini, Groq, DeepSeek, Mistral, OpenRouter, xAI, Ollama, and OpenAI-compatible custom endpoints. The web chat says a user-provided key stays in the browser and is sent only to the chosen provider.
