Description
A desktop overlay that sees your screen, answers questions about it, and points at the control you need. Ask a question; Handrail sends your screenshot and question to your chosen vision model, then draws arrows at real controls. It watches multi-step checklists as you work. Electron, Apache-2.0; local threads, OS-keychain API key, no account/telemetry; web search off by default. BYO OpenRouter/OpenAI/Anthropic key. Working daily by maker; author-only so far.
