Download Sigmora for Windows 10 and 11 (setup, 34 MB)
This is the official download page for Sigmora. The button gives you the original setup program, about 34 MB, built for Windows 10 and 11 (64-bit, x64). Compare its SHA-256 checksum with the published manifest before you run it. Pressing the button records the time, your IP address, your browser user agent and the referral source, then sends you to the installer. Updates arrive through the Update button in the app.
- Click the download button to get the setup program, about 34 MB. The installer build is the one that enables automatic updates, and your browser will save it to its usual download folder.
- Compare the SHA-256 checksum of the file with the value in the published manifest. The installer is not code-signed yet, so this check matters. The section below shows the exact Windows command.
- Run the setup. If Windows SmartScreen warns, choose More info and then Run anyway, but only after the checksum matches. If the checksum differs, stop and download the file again.
- Open the app, connect a model or use the built-in model, and choose the project folder that holds your training script. Then ask for a first small task, for example reading the script and explaining it.
No account is needed to run Sigmora. A cloud AI provider may charge separately for usage; that is between you and the provider. Prompts, including the text of files the agent reads, go to the model endpoint you pick, and only with a local model does nothing leave your PC. Chats, working folders and API keys stay on your PC. Use Sigmora only with code, data and computers you own or are allowed to use. The first run works best with a small script, so that you can read every diff and every result.
System requirements
Sigmora runs on Windows 10 or 11 in 64-bit (x64) form. Install Python first. It has to be installed where your training command runs: on your own PC, in WSL, or on your own server over SSH. Sigmora does not train anything itself, so the length of a run depends on your code and your hardware. A GPU server you own can be used over SSH, and Shell then runs your command on that server. The interface is available in 13 languages. Disk space for your data and logs is your own to plan, because experiment files can grow large. The app itself is small: the setup program is about 34 MB.
Updates
New versions are published automatically. When one is ready, the app shows an Update button, and you press it to install the new version. The installer build enables these automatic updates. The current version is 2.9.26, released on 2 Nov 2026. Read the release date on this page when you compare versions, and press Update inside the app when the button appears. If you ever need help or want to report a problem, use the Send feedback button inside the app.
Verify the Installer
certutil -hashfile "C:\Users\you\Downloads\<downloaded file>.exe" SHA256Open a terminal and run the command above. Replace the path in quotes with the real location of the file you downloaded. Compare the printed SHA-256 value with the value in the published manifest. If they match, run the installer. If they differ, do not run the file, and download it again from this page. The check matters because the installer is not code-signed yet. You do not need an account for any of these steps, and the command works in the standard Windows terminal without extra tools.
