Koofr vs SiYuan: at a glance
What is Koofr?
Koofr rebuilt its iOS app around automatic backup, becoming a destination rather than a folder.
Koofr is a European consumer cloud storage service, with Koofr Vault as its client-side encrypted layer. The dominant event of the past year is a complete rewrite of the iOS app, shipped as 4.0.0 in June: native Files app integration, automatic background photo and video backup, saving from other apps' share sheets, HEIC or JPEG choice on upload, labels, and search by file type and label. Document scanning followed in July. The rest of the feed is a mix of Vault polish, promotional discounts, and incident notices — a DDoS in April, a Google domain flagging in January.
What is SiYuan?
SiYuan re-tagged the same 3.8.2 changelog three times in thirty hours
The 3.8.2 line is a cumulative train: every tag republishes the full release list rather than a delta. Beta.1 was the superset, and beta.2, beta.3 and beta.4 all landed within thirty hours carrying a byte-identical changelog. The substance in that shared list is editor ergonomics (scrolling the viewport without moving the caret, configurable cursor surrounding lines), a broad mobile pass (configurable bottom bar, swipe gestures, marketplace access), and continued build-out of the AI Agent introduced in 3.8.0.

Koofr rebuilt its iOS app around automatic backup, becoming a destination rather than a folder.
◆ Current state
Koofr is a European consumer cloud storage service, with Koofr Vault as its client-side encrypted layer. The dominant event of the past year is a complete rewrite of the iOS app, shipped as 4.0.0 in June: native Files app integration, automatic background photo and video backup, saving from other apps' share sheets, HEIC or JPEG choice on upload, labels, and search by file type and label. Document scanning followed in July. The rest of the feed is a mix of Vault polish, promotional discounts, and incident notices — a DDoS in April, a Google domain flagging in January.
◆ Where it's heading
The company's attention is clearly on mobile parity with the large providers, and the sequencing shows it: rebuild the app, then add automatic backup, then add the capture features that make the phone a source rather than a viewer. Koofr Vault gets steady but smaller attention, keeping the encrypted layer close behind the main product. The recurring discount campaigns and gift card work suggest consumer acquisition matters as much as feature depth here.
◆ Prediction
Automatic background backup shipped on iOS with an explicit note about how iOS schedules uploads; the same capability reaching Android at comparable quality is the obvious next step, since the feed already treats the two platforms as a pair for Vault changes.

SiYuan re-tagged the same 3.8.2 changelog three times in thirty hours
◆ Current state
The 3.8.2 line is a cumulative train: every tag republishes the full release list rather than a delta. Beta.1 was the superset, and beta.2, beta.3 and beta.4 all landed within thirty hours carrying a byte-identical changelog. The substance in that shared list is editor ergonomics (scrolling the viewport without moving the caret, configurable cursor surrounding lines), a broad mobile pass (configurable bottom bar, swipe gestures, marketplace access), and continued build-out of the AI Agent introduced in 3.8.0.
◆ Where it's heading
Two surfaces are absorbing most of the work. The Agent keeps gaining reach rather than changing shape — image upload in agent chat, independent execution across sessions, skill inline markers, kernel log access for error analysis — all extensions of the capability 3.8.0-alpha.1 established. The plugin API is the other growth area, adding roughly a dozen hooks this cycle covering dock visibility, link interception, asset upload interception and breadcrumb buttons.
◆ Prediction
With four betas out and the changelog frozen since beta.1, the next tag in this line is most likely a 3.8.2 stable release.
