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
Promptchan AI — our take
A powerful NSFW image studio built around a clone-tweak-animate workflow; companion chat is secondary and Gem metering makes heavy video use costly.
- Strong image generation with deep prompt control
- Clone-and-tweak gallery workflow
- Gems roll over indefinitely
