How it works

From install to your first fix in minutes.

  1. 1

    Install

    One click, no admin rights. A short welcome tour shows you around.

  2. 2

    Connect a model

    Paste an API key for Z.AI, DeepSeek or any compatible service. You pay the provider directly.

  3. 3

    Describe the task

    Open a project folder and say what you need. Watch the agent work, then keep, undo or commit.

What you get

An agent that works in your project. Tools that keep you in charge.

It does the work

Searches and reads your code, edits files and runs commands in PowerShell. Every step is visible: thinking, searches, diffs and test output.

Undo anything

A checkpoint is saved before every message, including changes made by commands. Undo a turn, or rewind files and conversation to any message.

Review before you commit

The Changes panel lists every file the session touched. Accept, reject or commit file by file, with a commit message written for you.

Any model

Z.AI, DeepSeek or any OpenAI- or Anthropic-compatible service, even a local one. Give coding, planning and vision their own models, with fallbacks.

Parallel tasks

Run several tasks at once. Each works in its own git worktree on a new branch, so agents never collide with each other or with your checkout.

Git and GitHub

Sign in with GitHub, clone, publish, pull and push. Restore points save your whole folder before every risky move.

Keys stay on your PC

API keys are encrypted with Windows DPAPI and never shown to the interface.

No servers in between

Your code goes only to the model you choose. Sessions and usage stay on your computer.

Nothing is final

Checkpoints never touch your project's own .git. Keep only what you accept.

FAQ

Questions, answered.

Which models can I use?

Z.AI (GLM) and DeepSeek work out of the box with an API key. Any other service that speaks the OpenAI or Anthropic API can be added, including local servers such as Ollama.

What does it cost?

The preview is free. You pay your model provider for what you use; Kosmora shows the cost of every session and request as it happens.

Do I need Git?

For undo, change review, parallel tasks and GitHub, yes: install Git for Windows. Everything else works without it.

Is there a macOS version?

It is in the works. The preview runs on Windows 10 and 11 (64-bit).

How do I uninstall it?

From Windows Settings → Apps, or with Uninstall.exe in the install folder. Your projects and settings are not deleted.

Try it on your project.
