Best for	Developers building custom agents for their own company/product.	Developers. Non-developers who want to ship working code.	Podcasters, course creators, anyone editing talking-head content.	Indie game devs, illustrators, anyone training custom style models.
Strengths	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	Edit audio/video by deleting text Overdub (voice clone) for fixes Strong collaboration + remote recording	Train your own models on your style/character Great for game art + concept art Generous free tier
Weaknesses	Developer-only You build the UI	Can feel overwhelming for non-coders Expensive at scale	Not a traditional NLE — some workflows awkward Overdub ethics require care	General output behind Midjourney Can be overwhelming
Kai's verdict	S-tier for builders. The right primitives. What Kai is built on under the hood.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.	A-tier for creators training custom looks. B-tier for general use.
