Synop

Purpose: Synop turns long YouTube videos into short, high-signal summaries tailored to students, researchers, or creators.
Library: Its searchable library includes a cross-video topic map, full-text search, and a feature to ask questions across the library.
Study tools: Study Mode creates flashcards and quizzes, supports spaced-repetition review, and can turn a playlist into an Anki deck.
Video analysis: Per-video analysis includes semantic topic clusters, a multi-speaker debate matrix, freshness checks, and bias critique.
Channel watchlist: Users can follow channels and have new uploads automatically summarized into their library.
AI providers: Synop accepts OpenAI-compatible providers and lists OpenAI, DeepSeek, Groq, OpenRouter, Gemini, and local Ollama among its provider options.
Exports: Summaries can be exported as Markdown or PDF, or synced to Obsidian and Notion with generated wiki-links.
Languages: The official site says users can summarize and chat with videos in over 12 languages.
Privacy: The project says summaries and notes are stored in a local SQLite database, there is no Synop server, and AI keys are stored in browser local storage and sent to the selected provider per request.
Local provider guard: Custom provider URLs are checked against private, metadata, and localhost addresses; self-hosters can opt in to local providers with ALLOW_LOCAL_PROVIDERS=true.
Setup requirements: The README lists Node.js 18+ and an AI API key as requirements for setup.
Self-hosting: Synop can run wherever Node.js runs, including a home server, Raspberry Pi, or VPS, and supports optional Postgres for syncing across devices or multi-user use.
License: The project is distributed under the MIT License.
Intended users: The README describes persona-specific workflows for students, researchers or analysts, and creators or writers.
