Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Pricey for production apps Less voice variety than ElevenLabs Platform lock-in	Pricey for serious volume Long shots still feel off Ethics — easy to misuse	Not a traditional NLE — some workflows awkward Overdub ethics require care
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.	S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.	S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
