Tagline	AI search done right. Cited answers, not chat theater.	Prompt to UI design. Figma-ready outputs.	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.	Cognition Labs' autonomous coding engineer.

Pricing	Free + $20/mo Pro	Free trial + paid plans	Waitlist / Beta (pricing not yet disclosed)	$500/mo
Best for	Replacing Google for any question where you want a cited answer in seconds.	Designers brainstorming first drafts.	iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.	Engineering teams offloading tickets. Ops/platform work.
Strengths	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Prompt-to-UI with real layouts Exports to Figma Faster than hand-designing from scratch	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	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did
Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Output needs designer polish Pricing unclear / changes often	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	Expensive Best for well-scoped tasks Not for solo hobbyists
Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	B-tier. Useful for first drafts. v0 is the better bet for shipping code.	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.)	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
