Strengths	Great enterprise story Works in your existing IDE Chat + autocomplete	300+ models from one endpoint Automatic fallbacks between providers No subscription — just pay what you use	Native Google Workspace integration Very long context (1M+) Deep Research feature Free tier is generous	Brainstorm, expand, rewrite modes designed for fiction Story Bible for character + plot tracking Understands voice + tone better than generic chatbots
Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Slight markup over direct API Some provider features not exposed	Writing quality trails Claude Over-refusals on edge content UI is cluttered	Pricey for casual use Fiction-only focus — not for business writing
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for model-shopping. I use this for every prototype before committing.	A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.	S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
