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 Tana?
Tana races toward ambient AI assistant — voice commands now execute silently without interrupting you
Tana has shipped three major voice and agent capabilities in quick succession: a multitasking background agent that handles multiple requests simultaneously while you are in a meeting, auto-detection of unscheduled external meetings, and most recently a Hey Tana trigger that silently executes commands without entering a voice session at all. A native Calendar view also landed in the same release. The product has moved far past note-taking into ambient meeting assistant territory.

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.

Tana races toward ambient AI assistant — voice commands now execute silently without interrupting you
◆ Current state
Tana has shipped three major voice and agent capabilities in quick succession: a multitasking background agent that handles multiple requests simultaneously while you are in a meeting, auto-detection of unscheduled external meetings, and most recently a Hey Tana trigger that silently executes commands without entering a voice session at all. A native Calendar view also landed in the same release. The product has moved far past note-taking into ambient meeting assistant territory.
◆ Where it's heading
Every recent release adds ambient presence — Tana wants to run in the background of your workday, not only when you choose to open it. The combination of silent command execution, meeting capture, and calendar integration points toward a product that acts as a persistent AI colleague rather than a structured note-taking tool.
◆ Prediction
Tighter integration between calendar events and AI briefs is the likely next move, along with expansion of which external tools the background agent can act in. Whether Tana can hold the ambient-assistant position depends on how reliably the background execution performs across different meeting platforms.
