Point at your repo
Start inside the target project so files, command output, and project memory attach to the right repository.
cd your-project && reasonix codeGive it a task
Describe the goal in plain language; Reasonix can plan first and keep the diff reviewable.

Use read-only planning when you want to review the approach before write operations.

Switch for a hard refactor or a long debugging path that needs more model effort.

/doctorProduct overview
DeepSeek Reasonix built for long, cheap sessions.
Direct DeepSeek path, not a wrapper
Compared with generic OpenAI-compatible tools, Reasonix is designed around the DeepSeek path: low-cost iteration by default, with stronger reasoning when the task needs it.
Lower-cost long sessions
Compared with agents that spend heavily on repeated context, Reasonix is better suited to sustained debugging, refactors, and multi-hour work.
Terminal and desktop entry points
Compared with tools tied to an IDE or web app, Reasonix can start in the project terminal and also offers a desktop client.
Plan gates for code edits
Compared with agents that edit immediately, Reasonix can show the plan first, then confirm risky changes, commands, and write boundaries.
MCP, Skills, and Memory
Compared with fixed-function agents, Reasonix can connect external tools and preserve project-specific skills and memory.
Reviewable run history
Compared with one-shot chats, branches, checkpoints, and command history make debugging, handoff, and resuming easier.
