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.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.
