Best for	Developers. Non-developers who want to ship working code.	Teams with GitHub already. Devs who don't want to change IDEs.	Travel planning, shopping comparisons, deep research where you want an artifact back.	Anyone who wants top-tier video quality for less.
Strengths	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	Great enterprise story Works in your existing IDE Chat + autocomplete	Sparkpages = curated multi-source mini-articles Agent can book, compare, shop Autopilot agent for long tasks	Very strong motion + physics Often beats Runway on realism Great price
Weaknesses	Can feel overwhelming for non-coders Expensive at scale	Less agentic than Cursor/Claude Code Model quality varies	Early-stage — rough edges Less reliable than Perplexity for simple questions	UX is rough for English speakers Queue times
Kai's verdict	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. Bet on this one — the Sparkpage format is genuinely new.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
