Tagline	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.	Google's answer. Best integrated with Workspace + free for a lot.	Chat with your data. Upload a CSV, ask questions, get charts.
Category	Agents	Research	Chatbots	Data
Pricing	Waitlist / Beta (pricing not yet disclosed)	Free + $20/mo Pro	Free + $20/mo Advanced (bundled with 2TB Drive)	Free + $20-$65/mo
Best for	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.	Anyone already on Google, research tasks, summarizing long documents.	Analysts, founders, anyone with a spreadsheet + a question.
Strengths	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	Native Google Workspace integration Very long context (1M+) Deep Research feature Free tier is generous	Handles complex CSVs + spreadsheets Generates real Python analysis + charts No technical setup
Weaknesses	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	Writing quality trails Claude Over-refusals on edge content UI is cluttered	File size limits Can hallucinate on messy data
Kai's verdict	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.	A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.	S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.
