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
Chai — our take
Low-friction and cheap to try, but the free message cap makes Premium near-essential.
- Huge bot library
- Very easy to start
- Cheaper annual plan
