Tagline	Cognition Labs' autonomous coding engineer.	An agentic iPhone home screen that replaces your static icon grid with AI widgets that proactively surface health, calendar, finance, and local context — without you having to open a single app.	AI search done right. Cited answers, not chat theater.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.
Category	Agents	Agents	Research	Coding
Pricing	$500/mo	Waitlist / Beta (pricing not yet disclosed)	Free + $20/mo Pro	Part of Claude Pro/Max/Team plans
Best for	Engineering teams offloading tickets. Ops/platform work.	iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.	Replacing Google for any question where you want a cited answer in seconds.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.
Strengths	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did	Ambient, proactive intelligence delivered via native iOS widgets — no app-switching required Cross-domain context: health, calendar, email, finances, and local recommendations in one layer Works within iOS permission model (no jailbreak or sideloading), making App Store approval plausible Strong pre-launch signal: 25k+ waitlist and backing from a16z, True Ventures, and SV Angel	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks
Weaknesses	Expensive Best for well-scoped tasks Not for solo hobbyists	Still pre-launch / beta — zero proven track record and no public pricing yet iPhone-only by design, which immediately locks out half the smartphone market Battery drain and privacy concerns from constant ambient context scanning are real and unresolved	Not a general chatbot Answers can be shallow on complex topics	Terminal-based — learning curve Can't be used without Claude subscription
Kai's verdict	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	The concept is genuinely compelling — turning the home screen into a living AI layer is a smarter bet than yet another chat interface — but this is vaporware until it ships publicly and we see whether Apple's sandbox lets it breathe. (Verdict pending Phi's full review.)	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
