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.

About

99 Tasks

Read full description

I got 99 tasks, but distraction ain't one. Most task apps trap you in an infinite backlog of forgotten to-dos, complex project hierarchies, and monthly subscription taxes. 99 Tasks cuts through the noise. It gives you exactly 99 private, local-first slots for your active work — calls, payments, errands, follow-ups, and reminders. When your stack is full, you finish what's there before adding more. The constraint IS the superpower. What you can do in 30 seconds: • Capture a task by typing — natural language parses categories, due dates, and slots inline • Tap a row's icons to set focus, important, My Day, reminder, notes, or clear • Swipe left to clear, swipe right to focus • Find any task by what it means, not just the words you used • Set a local reminder in one tap • Plan your day with My Day — the app suggests overdue and due-today items for you Why 99 Tasks instead of another todo app: • Exactly 99 slots. No infinite backlog. No boards. No projects. • Local-first. Your tasks live on your device. Sync is optional, not required. • No account. No email. No password. Open the app and start. • One-time $4.99 Lifetime. No monthly subscription. Three days free to try everything. • On-device semantic search — your task contents never leave your device. • iOS home-screen widget in three sizes. Mac menu bar companion. Built for: • People with too many task apps who keep starting new ones • Founders, operators, freelancers, and builders who live in many apps • Anyone with attention friction who benefits from a fixed visual stack • Mac users who want a menu bar task companion • People who want a private paid utility instead of another account-based todo app
