## What is Trelk?

Trelk is your personal knowledge engine. Save anything you read — articles, research papers, YouTube videos, PDFs, newsletters, documentation — and watch your understanding grow as AI reveals how everything connects.

No subscriptions. No cloud dependency. No data lock-in. Buy once, own it forever.

HOW IT WORKS
Save content from any source: share a link, scan a QR code, import a PDF, or write your own notes in the built-in Markdown editor. Trelk's on-device AI reads, summarizes, and indexes everything locally. As your library grows, Trelk automatically discovers connections between ideas — surfacing relationships you'd never find on your own.

YOUR PERSONAL KNOWLEDGE GRAPH
Every piece of content becomes a node in your knowledge graph. Trelk maps conceptual links between articles, papers, and notes — visually showing how topics relate across your entire library. Watch isolated readings transform into an interconnected web of understanding.

OPEN-SOURCE AI, ON YOUR DEVICE
Trelk ships with open-source models from Hugging Face that run entirely on your phone. No API keys, no subscriptions, no data leaving your device. Want more power? Bring your own OpenAI or Anthropic key, or download any GGUF model directly from Hugging Face.

ASK YOUR LIBRARY
Ask questions and get answers grounded in what you've actually read. Hybrid retrieval — full-text search combined with semantic understanding — finds the most relevant content across your entire library. Every answer includes source citations linking back to your original items.

FLASH REVIEW & SPACED REPETITION
Knowledge fades without review. Trelk generates flash review questions from your content and uses spaced repetition to help you retain what matters. Track your retention score, review streaks, and topic performance over time.

DAILY PULSE
Start each day with an AI-generated synthesis of your recent saves — key themes, emerging patterns, and suggested connections. Your Pulse dashboard shows reading activity, content trends, and progress at a glance.

COMMUNITY COLLECTIONS
Browse curated collections assembled by the Trelk community. Import entire collections with one tap. Create and share your own. Build knowledge together.

OPEN FORMATS, ZERO LOCK-IN
Your notes are Markdown. Your database is SQLite. Export your entire library as CSV or JSON anytime. Full backup and restore of your database and all downloaded files. Every byte of your data is in a format any tool can read.

BUILT FOR PRIVACY
All AI processing happens on your device. Your data never leaves your phone. No accounts required. Sync is optional — choose Dropbox, Google Drive, OneDrive, or iCloud on your own terms.

WORKS WITH EVERYTHING
Save from Safari, Chrome, or any app via the share sheet. Upload PDFs, Word documents, and Markdown files. Supports articles, research papers, YouTube videos, newsletters, documentation, and personal notes.

AVAILABLE IN 6 LANGUAGES
English, Portuguese, Spanish, French, German, and Italian.

Read more. Think deeper. Connect everything.
