Phone · Tablet · Your knowledge everywhere
Share URLs, scan QR codes, import PDFs, DOCX files, or write notes. Everything is automatically extracted, summarized, tagged, and embedded.
AI generates summaries, extracts tags, classifies content, and discovers connections to your existing library. Every item becomes part of your growing knowledge graph.
AI organizes your library into semantic clusters. Each dot is an item. Each color is a topic. Pinch to zoom, tap to explore. Watch new patterns emerge as your library grows.
The tag network graph shows which topics co-occur across your library. Tap any tag to see its connections and explore the items that share it.
Ask questions and get answers grounded in your own reading. Every response includes clickable source citations linking back to your original items.
Every morning, AI synthesizes your recent reading into a personalized briefing. Fresh connections between items are surfaced automatically. Never miss a pattern forming in your library.
AI-generated flash cards test your recall with spaced repetition scheduling. Track your retention rate, accuracy trends, and topic performance over time.
Browse curated reading lists built by the community. Import entire collections with a single tap. Every item gets processed, tagged, embedded, and connected to your library.
A full markdown editor with formatting toolbar and image insertion. Your notes are embedded and clustered alongside all your other content.
Track your reading streak, knowledge score, topic depth, and content mix. Earn milestones as your library expands. See how your knowledge evolves over time.
No subscriptions. No monthly fees. No usage limits. One purchase gives you the full app, every feature, and every future update.
No lock-in. No proprietary formats. Everything in Trelk uses open, portable standards you can read, export, and take anywhere. Your knowledge belongs to you — not to us.
Notes are stored as Markdown. Your database is SQLite — the most widely used database format in the world. No proprietary blobs, no walled gardens. Every byte of your data is in a format any tool can read.
Export your entire library as CSV or JSON anytime — every field, every tag, every connection. Import just as easily. Move between tools, run your own analysis, or archive everything outside the app. Zero friction in, zero friction out.
One-tap backup of your complete SQLite database and all downloaded files to your cloud. Restore on any device, any time. Items, tags, embeddings, connections, collections, downloaded content — everything preserved, nothing left behind.
