I built ThreadKeeper, an open-source Windows app to solve a problem I constantly face: losing my working context due to interruptions.

When testing local LLMs or building AI agents, I usually have multiple terminal windows, IDEs, and 20+ browser tabs open. If I get interrupted, recovering that exact state takes immense cognitive load.

How it works: You hit Ctrl + Shift + S. It instantly captures your open windows, browser tabs, and clipboard (first 200 chars), and saves the state entirely locally (%APPDATA%). It then uses an LLM to auto-generate a summary of what you were doing. Later, 1-click restores all those apps and tabs.

Privacy First (Ollama Support): I didn't want my code or private keys going to the cloud. You can use external APIs (Gemini/Claude) via BYOK, but it fully supports Ollama for 100% offline, local summarization. Zero data leaves your machine.

The elephant in the room (SmartScreen): This is a free, MIT-licensed MVP. I haven’t purchased an expensive EV code signing certificate yet, so Windows SmartScreen will show a warning. I know this is a friction point, but the source code is fully open on GitHub for anyone to inspect or build themselves.

I’d love to hear your feedback or roast my code!
