Trelk — Read, Think, Connect

Trelk — Read, Think, Connect is an AI personal knowledge management tool that saves, summarizes, and links everything you read directly on your device for researchers, students, and knowledge workers. Capture content by sharing URLs, scanning QR codes, importing PDFs and DOCX files, or writing notes, and let on-device AI automatically summarize, tag, and classify each item. Trelk combines full-text keyword search with semantic vector search, then maps your library as a force-directed knowledge graph that surfaces hidden connections and semantic clusters across articles, papers, and notes. You can chat with your entire library using Retrieval-Augmented Generation (RAG) with source citations, receive a daily AI briefing that synthesizes recent reading, and reinforce retention with AI-generated spaced-repetition flash cards. It works fully offline with zero configuration and can run on your favorite proprietary LLMs or open-source models from Hugging Face. Community collections let you import curated reading lists (via GitHub) or share your own. Trelk uses open formats and a buy-once, own-forever model with no subscriptions, accounts, or tracking — making it a private alternative for people who want a second brain that stays on their own hardware.

Researchers, students, and knowledge workers use Trelk to save, summarize, and connect their reading in a private on-device AI knowledge base.
