I can recommend sognoai.com couple things are different: context window goes up to 1M tokens, meaning it holds onto way more of your conversation instead of forgetting everything a few messages in, which is what happens with most free tiers. the voice side is real-time too, no transcribe-then-respond-then-read-aloud pipeline, it’s actually listening while you’re speaking, so you can interrupt mid-sentence the way you would with a real person.
honestly, the character library is at only a few hundred right now, nowhere close to the millions character.ai has, though if you’ve already built characters on chub, the tavern card imports directly so you’re not stuck rebuilding everything.
