Koofr vs Readwise
A side-by-side editorial comparison of Koofr and Readwise — release velocity, themes, recent moves, and the top alternatives to consider.
Koofr vs Readwise: at a glance
What is Koofr?
Koofr brings web-app link controls to Android days after a 24-hour DDoS.
Koofr is a privacy-focused cloud storage service. Its newest release gives the Android app the web app's advanced link settings: passwords, messages, QR codes, visit and upload counts, and receive links that route files to a folder via a unique email address. It lands three days after an incident report on a nearly 24-hour, extortion-driven DDoS, the third availability disruption since April.
What is Readwise?
Readwise splits its bundle into Reader-only and Highlights-only plans and renames its first app.
Readwise posts a weekly changelog. The October 23 release changes packaging: the original app is now Readwise Highlights, and users can subscribe to Reader or Highlights alone instead of the full bundle, switching plans themselves. The same week adds 38 Lifelike beta voices in 14 languages, rebuilds Daily Review audio on those voices, and makes YouTube transcripts twice as fast without filler words.

Koofr brings web-app link controls to Android days after a 24-hour DDoS.
◆ Current state
Koofr is a privacy-focused cloud storage service. Its newest release gives the Android app the web app's advanced link settings: passwords, messages, QR codes, visit and upload counts, and receive links that route files to a folder via a unique email address. It lands three days after an incident report on a nearly 24-hour, extortion-driven DDoS, the third availability disruption since April.
◆ Where it's heading
Product work is closing parity gaps across clients: a rebuilt iOS app in June, document scanning in July, browser-extension upgrades in September and now Android sharing. Running alongside it is a recurring availability problem (April DDoS, September data-center connectivity, October DDoS) that the entries show being handled reactively.
◆ Prediction
Expect the same link controls or other web-app features to keep moving into the mobile apps; whether Koofr ships visible resilience measures after the October attack is not clear from the entries.
Readwise
6.3COLLAB
Readwise splits its bundle into Reader-only and Highlights-only plans and renames its first app.
◆ Current state
Readwise posts a weekly changelog. The October 23 release changes packaging: the original app is now Readwise Highlights, and users can subscribe to Reader or Highlights alone instead of the full bundle, switching plans themselves. The same week adds 38 Lifelike beta voices in 14 languages, rebuilds Daily Review audio on those voices, and makes YouTube transcripts twice as fast without filler words.
◆ Where it's heading
Reader has been the main product thread for months (TTS, Ghostreader on GPT-6 Luna, video transcripts), and the plan split lets it be sold on its own. Lifelike voices are spreading from Reader's Listen into Highlights' Daily Review, so the two apps now share an audio layer while being priced separately.
◆ Prediction
Expect follow-up fixes around plan switching and more Lifelike voice tuning; Lifelike leaving beta is the most supported next feature step.
