Pi — our take
Completely free, genuinely warm, and no upsell wall. Not a roleplay product, but an excellent listener.
- Entirely free with unlimited voice
- Consistently rated the most empathetic free model
- No ads
Grok — our take
A general assistant first. Fine company for casual banter, but companionship is a sideline here.
- Looser tone than rivals
- Image generation included
- Standalone plan, no X account needed
