Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	Most mature video workflow Character consistency via Act-One Gen-4 quality is production-grade	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Searches 125M+ papers Extracts + synthesizes findings across papers Systematic review workflow

Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier. Market leader with reason. Start here for serious video.	S-tier for model-shopping. I use this for every prototype before committing.	S-tier for academic research. Nothing else comes close for systematic reviews.
