	Replit Agent A	Perplexity S	Skye A	DeepSeek S
Tagline	Replit's AI that builds + deploys full apps on their platform.	AI search done right. Cited answers, not chat theater.	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.	Chinese open-weight powerhouse. Crazy cheap, genuinely smart.
Category	Coding	Research	Agents	Chatbots
Pricing	$10-$25/mo Core/Teams	Free + $20/mo Pro	Waitlist / Beta (pricing not yet disclosed)	Free web + ultra-cheap API (~$0.14/M input tokens)
Best for	Teachers, students, prototypers, hackathon builders.	Replacing Google for any question where you want a cited answer in seconds.	iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.	Developers + cost-conscious builders. Anyone fine with self-hosting.
Strengths	Full-stack + DB + auth + deploy in one environment Great for teaching/learning Runs everything in-browser	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	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	Open weights you can self-host Strong reasoning + math Near-free API pricing DeepSeek-V3 / R1 are serious models
Weaknesses	Locked into Replit hosting Less code quality than dedicated IDEs	Not a general chatbot Answers can be shallow on complex topics	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	Data goes to servers in China — privacy concerns for business use Chinese policy filters English polish trails Western models
Kai's verdict	A-tier. Best for teaching a kid to code in 2026.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	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 price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
