Koofr vs Readwise: at a glance
What is Koofr?
Koofr's iOS app gets a text editor, and public links get minute-level expiry.
Koofr is a privacy-focused cloud storage service working through mobile parity with its web app. The November 3 release adds a text editor to the iOS app, improves editing documents in external apps through the Files integration, lets public links expire down to the minute, and gives paid users custom link passwords. It follows October's Android sharing upgrade.
What is Readwise?
Readwise launches Books, its own ebook store and reading app, a week after unbundling.
Readwise now sells three products. A week after splitting Reader and Highlights into separate plans, it launched Readwise Books on October 30: an iOS and Android ebook store and reading app stocked by the major publishers, with reading sessions, following other readers, and Kindle and Goodreads imports. The same release added 13 Books tools to the Readwise MCP server, moved podcast transcripts onto the YouTube cleanup pipeline, and lets the Reader API set reading progress.

Koofr
5.0COLLAB
Koofr's iOS app gets a text editor, and public links get minute-level expiry.
◆ Current state
Koofr is a privacy-focused cloud storage service working through mobile parity with its web app. The November 3 release adds a text editor to the iOS app, improves editing documents in external apps through the Files integration, lets public links expire down to the minute, and gives paid users custom link passwords. It follows October's Android sharing upgrade.
◆ Where it's heading
Since the iOS 4.0 rebuild in June, releases have steadily brought web features to mobile: document scanning, Android link controls, now an iOS editor. Sharing controls get tightened in the same releases, alongside an ongoing effort to recover from repeated DDoS disruptions.
◆ Prediction
Expect the text editor to reach Android and more link controls across apps, given the alternating iOS and Android parity releases.
Readwise
6.3COLLAB
Readwise launches Books, its own ebook store and reading app, a week after unbundling.
◆ Current state
Readwise now sells three products. A week after splitting Reader and Highlights into separate plans, it launched Readwise Books on October 30: an iOS and Android ebook store and reading app stocked by the major publishers, with reading sessions, following other readers, and Kindle and Goodreads imports. The same release added 13 Books tools to the Readwise MCP server, moved podcast transcripts onto the YouTube cleanup pipeline, and lets the Reader API set reading progress.
◆ Where it's heading
Readwise is moving from a layer on top of other people's reading apps to owning the purchase and the reading itself. The unbundle, the free Books app and the shared MCP server point to separate entry products that all feed the same account. Reader keeps its weekly cadence of TTS, transcript and parsing work underneath.
◆ Prediction
Expect weekly Books fixes and Kindle-import work, and a move from invite-only to open signup if the store holds up.
