SillyTavern x MegaNova: Connect Free AI Models via Forked API Source
AI roleplay is becoming a favorite way for people to explore creativity — whether you’re building characters, writing stories, or just chatting with your favorite AI companion. But privacy, performance, and cost often stand in the way of a good experience.
That’s where SillyTavern, combined with MegaNova AI’s free API, changes everything.
This setup lets you run immersive, private roleplay sessions with high-quality open models with no subscriptions, no trackers, and no limits.
What Is SillyTavern?
