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
ChatGPT — our take
Not built as a companion, but its memory and voice mode make it a legitimate daily chat partner.
- Best general reasoning and writing
- Strong voice mode
- Memory across conversations
