Long-form sources are condensed into short readable or listenable summaries, with timestamped key moments for video and audio content.
Ask questions against your saved library using ChatGPT, Claude, Gemini, Grok, DeepSeek or other supported models, so answers stay grounded in your material.
Related ideas across items are linked automatically and mapped in a knowledge graph so you can follow a topic from one source to the next.
