In Settings → Models & providers, sign in with ChatGPT or GitHub Copilot, paste an API key, or use a model running on your PC.
Open a project folder and say what you want, like you'd tell a teammate. AFH sets a goal, makes a plan and gets to work.
| System | Windows 10 or 11, 64-bit |
| Disk | About 430 MB once installed, plus your threads |
| Models | A ChatGPT or Copilot plan, any API key, or a model running on your PC |
| Internet | Needed for online models. Local models work offline. |
| Optional | Git for worktrees · Chrome or Edge for the browser tool |
AFH checks this site for new versions and downloads them in the background. When one is ready you'll see Restart to update — or it installs the next time you quit.
Turn it off, or check by hand, in Settings → About → Updates.
To make sure the installer arrived intact, compare its SHA-512 with the one above:
Get-FileHash .\AFH-Setup-1.8.7.exe -Algorithm SHA512Questions
Yes. AFH itself costs nothing and needs no account. You pay your model provider as usual — or nothing extra if you sign in with a ChatGPT or Copilot plan you already have, or run models on your PC.
No. You can sign in with ChatGPT (Plus, Pro or Team) or GitHub Copilot, or use a model running locally in Ollama, LM Studio, vLLM, llama.cpp or Jan. API keys work too, for 228 providers.
Only to the model providers you set up. Threads, settings and keys stay on your PC in %USERPROFILE%\.afh. There's no telemetry.
SmartScreen warns about apps it hasn't seen many times before. Choose More info → Run anyway. You can check the file's SHA-512 against the one on this page first.
Not yet — AFH is Windows only for now.
Open Settings → Apps in Windows, find Agent Flow Harness and choose Uninstall. Your threads and keys stay in %USERPROFILE%\.afh; delete that folder to remove them too.
