Firefly

We all collect information from everywhere — screenshots, bookmarks, notes scribbled on the fly — but it piles up and becomes impossible to use. Firefly is an open-source, lightweight AI-powered memo hub that makes information collection not just manageable, but genuinely interesting.

It lets you hand over your collected fragments to AI for processing — summarizing, generalizing, and organizing them — and save the results with one click. Firefly supports OCR image recognition, shortcut key collection, word-marking icon collection, and comes with a powerful Markdown editor supporting virtually all Markdown elements. Through the integrated Copilot Hub, you can even use your own data to train models and build a personalized knowledge base that truly reflects how you think and work.
