What is Kagi Search?
Kagi is unbundling itself: search as an API, Assistant as an app, AI as a switch.
The dated part of this feed stops in April on housekeeping releases — reliability work, refinements, a Small Web expansion. Everything since sits in undated rows and is more substantial: the Search API went to public preview in May carrying each account's own lenses and blocklists, June started rebuilding search widgets, July added a global off-switch for AI in search, and July 30 put Kagi Assistant on iOS and Android as a standalone app.
What is AFFiNE?
AFFiNE just cut its AI loose from a fixed provider — bring your own keys, your own models, per workspace.
AFFiNE publishes from two trains simultaneously — dated canary builds and 0.27.x betas — so the same pull request often appears twice with different version numbers. Most of the recent output is dependency automation: setup-python, actions/cache, RevenueCat SPM bumps. The substantive work sits on the server: blob sync with presigned URLs for S3 and R2, document garbage collection reliability, and now a rebuild of how Copilot gets its models.

Kagi Search
0.0COLLAB
Kagi is unbundling itself: search as an API, Assistant as an app, AI as a switch.
◆ Current state
The dated part of this feed stops in April on housekeeping releases — reliability work, refinements, a Small Web expansion. Everything since sits in undated rows and is more substantial: the Search API went to public preview in May carrying each account's own lenses and blocklists, June started rebuilding search widgets, July added a global off-switch for AI in search, and July 30 put Kagi Assistant on iOS and Android as a standalone app.
◆ Where it's heading
Kagi is separating what used to be one subscription into distinct products with distinct surfaces: a search index other people can query, an assistant that lives on a phone, and a search page where the AI layer is optional. The through-line is user control — preferences that follow the API key, widgets that can be switched off individually, threads that can be exported or deleted in bulk — which is the one thing an ad-funded competitor cannot match on. Growth now depends on those surfaces rather than on convincing people to change their default search engine.
◆ Prediction
The Search API is the piece with launch details still outstanding, so expect it to leave preview with firm pricing and the beta users migrated; the mobile Assistant is described as a first step, which points to the missing platform features arriving next.
AFFiNE
7.5COLLAB
AFFiNE just cut its AI loose from a fixed provider — bring your own keys, your own models, per workspace.
◆ Current state
AFFiNE publishes from two trains simultaneously — dated canary builds and 0.27.x betas — so the same pull request often appears twice with different version numbers. Most of the recent output is dependency automation: setup-python, actions/cache, RevenueCat SPM bumps. The substantive work sits on the server: blob sync with presigned URLs for S3 and R2, document garbage collection reliability, and now a rebuild of how Copilot gets its models.
◆ Where it's heading
The server is where AFFiNE is investing, and the shape of that investment is self-hosting. Presigned upload URLs configurable per storage provider, doc GC hardening, and now workspace-level model profiles all point at the same customer: someone running AFFiNE on their own infrastructure who wants the AI features without routing content through AFFiNE's vendor of choice. Removing the legacy provider-specific settings in the same change says this is a replacement, not an option.
◆ Prediction
With provider catalogs and managed tiers now in the model, the next moves are likely on the governance side — surfacing which models a workspace permits and what they cost — since the change also stripped token-cost and provider metadata out of public responses.
