A Readwise alternative where your Kindle highlights are working memory

Every passage you've ever flagged, in the conversation where it matters

You highlight a book because you want that idea later. Readwise stores it and sends it back at 7am with a few others, a daily catechism of your own thinking. It's lovely, and it's one-way: the highlights wait for you to come back. Fasrad makes them active. Your Kindle library syncs nightly and every passage you've flagged becomes a note in your second brain. Ask a real question and your assistant draws on them, citing the book and the author.

Here's what changes:

• Ask when you need it. "What did Vaclav Smil say about energy density?" comes back from your own marginalia, with the book and location attached. Author and date are structured filters, so the match is exact.
• Highlights weave into briefings. Your morning brief can pull random passages from any notebook you choose, like a paragraph from Juvenescence or a Soviet joke, and set them beside the day's news and calendar. You never open a separate app.
• Drafts cite your reading. Ask your assistant for a memo or an email and the passages you actually annotated surface inline.
• Auto-sync, no daily ritual. Once a day the Fasrad Scanner extension pulls new Kindle highlights from read.amazon.com and skips books that haven't changed. You don't need an API key, Whispersync setup or a Readwise subscription.
• A shelf, too. Your whole Kindle library becomes a browsable read shelf with covers. Ask "what books about AI have I read?" and they come back as cards. Ask "what should I read next?" and you get new books grounded in what you've highlighted, each linking to Amazon. Readwise resurfaces what you've read, and Fasrad also points you to what's next.

Switching from Readwise is one Scanner install and a click. Highlights land in a Kindle Highlights notebook with one sub-notebook per book. Each note carries the book title, author, ASIN and Kindle location. Re-syncs are diff-based, so nothing duplicates.

Frequently asked questions

How does Kindle highlight sync work?

Install the Fasrad Scanner browser extension, sign in to read.amazon.com once in any tab and click Sync in the extension popup. The extension reads your highlights from Amazon's own notebook page (no public API, no third-party auth), creates one note per highlight and arms a daily auto-sync. Re-syncs skip books with no new highlights.

Do I need a Readwise subscription or any Amazon developer keys?

No. The Scanner uses your own logged-in Amazon session to read the public notebook page. There's nothing to subscribe to or authorize, and no API keys to keep alive.

Can I search highlights by author?

Yes. Author is a structured field your assistant queries directly. "What did Stuart Russell say about the off-switch problem?" returns highlights from his books, where a fuzzy match on the highlight text would only give you a vector guess.

What about my existing Readwise library?

You get the same highlights back by re-syncing Kindle from the source, since every flagged passage is still on Amazon's notebook page. Non-Kindle sources (Snipd podcasts, Matter, web-clipper articles) are on the import roadmap. Today you forward or paste them in and the agent files them as notes alongside the Kindle library.

Does Fasrad do spaced repetition / daily review?

Yes, woven into your morning. Your daily briefing can include N random highlights from notebooks you pick ("5 random from Kindle Highlights and Quotes"), shown beside news, calendar and weather. It's the Readwise resurfacing idea without a separate review queue.

Will my Notion / Obsidian sync still work?

Fasrad becomes the system of record, so there's no write-back sync to keep running. Most users move highlights here and drop the Readwise → Notion sync entirely. You can export any note or notebook to markdown anytime.

What if Amazon changes its notebook page?

Sync is monitored end to end, and updates ship through the normal extension update channel. Firefox auto-updates within hours, and Chrome goes through Web Store review. You don't have to do anything.
