Tagline	AI slide decks that don't look AI-generated.	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.	The GitHub of AI. Models, datasets, spaces — all in one.
Category	Productivity	Agents	Research	Dev Platform
Pricing	Free + $10-$20/mo	Waitlist / Beta (pricing not yet disclosed)	Free + $20/mo Pro	Free + $9-$20/mo + enterprise
Best for	Pitch decks, proposals, internal presentations — fast.	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.	Any ML/AI developer. Hobbyists exploring open models.
Strengths	Strong templates Decks, docs, webpages Doesn't look generic	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	Largest open-source AI model hub Hosted inference via Spaces + Inference Endpoints Great community
Weaknesses	Locked into Gamma's format Export quality varies	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	Overwhelming for beginners Hosted inference pricing varies
Kai's verdict	A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.	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 infrastructure. The one platform every AI dev eventually uses.
