What is Koofr?

Koofr's rebuilt iOS 4.0 with native Files integration is its best shot at mainstream mobile relevance

Koofr is a privacy-focused cloud storage service that ships at a slow but deliberate cadence. The defining move of this period was the completely rebuilt iOS 4.0 app with native Apple Files integration — Koofr storage now appears and behaves like iCloud Drive within the iOS Files picker, with automatic background photo backup added as a second headline feature. Post-launch additions (document scanning, browser extension bulk-image saving) are competent capability fills. Two service incidents in six months — a DDoS in April and a connectivity issue in September — are an operational note without product implications.

What is SiYuan?

SiYuan v3.8.4 beta cycle adds agent-controlled database fields, MiniMax image gen, and skill file management

SiYuan is deep in the v3.8.4 pre-release cycle, now at beta.4, shipping a dense stream of enhancements across each daily build. The defining theme of this release cycle is agent-control expansion: the AI can now configure database fields, manage skill files, stream Markdown previews, and use custom AI provider headers — moving SiYuan from a tool where AI assists with writing to one where AI can reshape the workspace structure itself. Mobile UX and PDF annotation improvements are running in parallel.

Koofr's rebuilt iOS 4.0 with native Files integration is its best shot at mainstream mobile relevance

◆ Current state

Koofr is a privacy-focused cloud storage service that ships at a slow but deliberate cadence. The defining move of this period was the completely rebuilt iOS 4.0 app with native Apple Files integration — Koofr storage now appears and behaves like iCloud Drive within the iOS Files picker, with automatic background photo backup added as a second headline feature. Post-launch additions (document scanning, browser extension bulk-image saving) are competent capability fills. Two service incidents in six months — a DDoS in April and a connectivity issue in September — are an operational note without product implications.

◆ Where it's heading

Koofr is doubling down on native mobile integration rather than web or cross-platform expansion. The iOS 4.0 rewrite, Files integration, document scanning, and background backup are all iOS-first moves. There is no signal of comparable Android investment or web-app parity work in this changelog. The trajectory positions Koofr as a privacy-respecting alternative to iCloud for iOS users, with the Files integration as the primary stickiness lever.

◆ Prediction

The natural follow-on from iOS Files integration is iOS Shortcuts support and possibly a Lock Screen widget — features that make Koofr a power-user option on iPhone without requiring users to leave their existing workflows. An Android parity release at similar scope is plausible within 12 months if the iOS momentum validates.

SiYuan v3.8.4 beta cycle adds agent-controlled database fields, MiniMax image gen, and skill file management

◆ Current state

SiYuan is deep in the v3.8.4 pre-release cycle, now at beta.4, shipping a dense stream of enhancements across each daily build. The defining theme of this release cycle is agent-control expansion: the AI can now configure database fields, manage skill files, stream Markdown previews, and use custom AI provider headers — moving SiYuan from a tool where AI assists with writing to one where AI can reshape the workspace structure itself. Mobile UX and PDF annotation improvements are running in parallel.

◆ Where it's heading

SiYuan is building toward an agent-orchestrated personal knowledge base, where the AI layer can modify not just content but the organizational schema. The skill file management system suggests an emerging plugin-like architecture for agent behaviors. As multimodal generation (MiniMax image support) gets wired in, SiYuan's trajectory is toward a locally-run AI workspace that rivals cloud-based tools without the data-residency trade-off.

◆ Prediction

v3.8.4 stable will ship soon given the move to beta.4. The agentic features (database field configuration, skill management) will attract integrations from local-first AI workflow builders. Expect MiniMax and other provider integrations to expand in the next cycle.
