Kai's verdictB-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. Great price/performance. Go here if ElevenLabs is too expensive.S-tier for open-source model APIs. The default in this space.
