What it is
Reasonix is an open-source AI coding assistant that runs on your own computer. You describe a task in plain language, and it reads code, edits files and runs commands and tests inside the project folder you choose, showing you each step. You choose the AI model: a DeepSeek preset is built in, and any OpenAI-compatible service can be added, with payment going directly to the model provider.
- Asking it to add a feature or fix a bug in a project folder
- Running tests and commands as part of a task while reviewing each step
- Rewinding file edits made by its edit tools by conversation turn
- Using it from a terminal script with reasonix run "task"
Great for
- Developers who want an AI assistant to make multi-step changes in a local project
- People who want to choose or switch their own model provider
- Users who want to approve each action or review a plan before work starts
- Those who prefer a desktop app, terminal, browser, or VS Code extension interface
Not ideal for
- People who want a hosted service with no setup or API key, since you must supply a model provider and key
- Anyone who expects rewind to undo shell command side effects, because the README says only files changed by its edit tools are covered
- Those who need a fully offline setup, since the model is a service you configure and it receives what it reads

Strengths
- Runs on your computer and works inside the project folder you pick
- Lets you choose the permission level, from asking every time to limited autonomy
- Offers several interfaces: desktop app, terminal, browser, and editor via ACP
Trade-offs
- You must supply and pay for your own model provider and key
- Rewind does not cover changes made by shell commands
- The README is truncated and does not fully document setup details for every platform
