What it does
Everything a reading list should have done from the start
Save it, understand it, find it again, and actually get back to it — without another subscription holding your archive hostage.
Everything a reading list should have done from the start.
Everything a reading list should have done from the start.
You choose the model, the server, and whether anything leaves your machine at all.
The problem was never saving. It's getting back to what you saved — this is built around that part.
Every save becomes searchable, connected, and exportable — a real archive, not a growing pile.
Follow what you care about, see the good news first, and get the day summed up.
Read, listen or send it to your Kindle — whenever you have a free minute.
A built-in RSS reader
Follow blogs and news sites, filter by source, tag, date or mood, import OPML, and summarize any item in one click. Play podcast feeds in the extension and get an optional AI recap; feeds and favorites stay on your device.
YouTube videos, from their captions
Summarize YouTube videos from their captions, get key points in your language, and ask follow-up questions with source citations.
20+ languages, cross-platform
Read and summarize in 20+ languages using the extension, native side panel, or bookmarklet when the extension cannot reach a page.
Instant read: listen while it writes
Listen while the summary is written: title first, then sentence by sentence, with pause, mute and speed controls. Replay it from any card.
Mood filter and mood over time
Rate headlines from heavy to good, filter for good news, and track your reading mood by day, week or month.
An analytics report of your reading
See reading streaks, time saved by summaries, activity, weekly topics and a word cloud computed from your own library.
Questions
Before you install
Search the answers by topic, provider, privacy, archive or platform.
Do I need an account to use it?
No. Install it, bring your own AI provider key or use a local Ollama model, and start saving. An account is only needed for optional byphil Cloud access or extra Kindle/LocalSend sends.
What actually leaves my browser?
Only the summarization request goes to the AI provider you configured. RSS also needs requests to your subscribed feeds; an AI recap sends headlines and short snippets only when you request it. Search, duplicate detection, tags and recommendations run locally. See the on-device architecture →
Which AI providers and models are supported?
You can use OpenAI, Gemini, Mistral, DeepSeek, a compatible custom endpoint, or a local Ollama model. Bring your own key, or use optional byphil Cloud access. Learn how BYOK works →
Can I summarize PDFs, YouTube videos and RSS items?
Yes. Summarize PDFs opened in the browser or attached from disk, YouTube videos through their captions, and articles from the built-in RSS reader. Watch the workflow videos →
How reliable are the AI summaries?
AI output can be wrong and does not replace checking the source. Follow-up answers show the passage they rely on, so you can compare the summary with the original page. Learn the 10-second source check →
Which browsers and platforms are supported?
Use the browser extension, native side panel or bookmarklet. An Android companion adds links from your phone; iOS is not available yet.
What happens to my saves if I stop supporting the project?
Your archive stays exactly where it's always been — in your browser's local storage on your device. The Support Pass only gates cloud-dependent extras (byphil Cloud AI access, unlimited Kindle/LocalSend sends), never access to what you've already saved. See how Digest makes saves useful again →
Is this open source?
Yes — the extension's source is public on GitHub, under the AGPL-3.0 license. It is free for personal, educational and non-profit use; companies that want to use it outside the AGPL's terms can get a commercial license.
