What is Readwise?
Readwise is a bot that fetches content from web pages to sync highlights and annotations from articles, ebooks, and other reading materials into users' Readwise accounts. The service helps users collect, review, and retain their reading highlights through spaced repetition and integration with note-taking applications. You can set up Agent Analytics to see when Readwise visits your website.

Why Is Readwise Visiting My Website?
Someone shared a link to your page. Readwise fetched it to build a preview card, and each new share may trigger another request. A spike often means your content is circulating more widely.
Should I Block Readwise?
Usually not. Blocking Readwise may leave shared links without a title or image, making them less inviting to click. If it begins fetching at unexpected volume, try rate limiting before blocking it outright. For context, 7% of the top websites we track currently have robots.txt rules for Readwise.

Frequently Asked Questions
What Traffic Patterns Should I Expect From Readwise?
Readwise usually makes a single request within seconds of a URL being shared, without crawling further. Traffic rises and falls with sharing activity, so a widely circulated link can produce a sharp burst of fetches.
Does Readwise Follow Robots.txt Rules?
No. Readwise is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Is Readwise Used for AI Model Training?
Not ordinarily. Readwise is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Readwise Affect AI Search or Citations?
Not directly. Readwise's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does Readwise Access Private Content?
No. Readwise has no credentials and should access only the public URL and assets needed for a preview. It does not continue through the rest of your site.
How Can I Verify a Request From Readwise?
Agent Analytics tracks Readwise visits in real time. You can also check your server logs for requests whose user-agent string contains "Readwise". Look for a page and its preview assets being requested without follow-up navigation. Because Readwise does not publish a verification method, any client can claim its identity and a log match is only a clue.
