Trelk vs Ember

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.
