AI browser companion for chat, summaries and a personal knowledge base

Turn lengthy web pages, documents and research papers into concise key points you can edit, save or share with colleagues.
Extract summaries, timestamps and key takeaways from videos so you can jump to the moments that matter instead of watching end to end.
Store and organize everything you capture by topic, tag or project in a searchable dashboard you can reach from any device.
