Hi everyone, I’m the developer of ASTERON, a Windows app for finding information again in documents you already have. It searches inside local PDF, Office and HWP files, and lets you ask questions about them with source references.

Document search runs locally. The Q&A uses Google Gemini, so your question and relevant excerpts are sent to Gemini when you ask something.

I’m still the only active user, so I wanted to share it here and see what people think. If you’d like to try it, leave a comment and I’ll set up a beta account, free through October 26, 2026.
