Dyva uses a proprietary AI engine that has been fine-tuned specifically for personality-driven conversation. There is no model picker, no dropdown menu, and no confusing configuration. Every character on every plan uses the same underlying engine. This means you never have to worry about choosing the right model. The engine handles personality consistency, memory retrieval, voice synthesis, and knowledge base lookups behind the scenes. It is optimized for natural dialogue, character fidelity, and low-latency responses.
Plan Differences
The AI engine is the same across all plans. What changes between tiers is access to features and usage limits:
Free — 50 messages/day, 1 character, basic memory, text chat only
Plus ($12/mo) — 500 messages/day, 3 characters, full persistent memory, voice chat (60 min/mo)
Pro ($30/mo) — 2,000 messages/day, 10 characters, unlimited voice, custom voice clones, API access, integrations
Creator ($50/mo) — 5,000 messages/day, 20 characters, everything in Pro plus Studio analytics, marketplace publishing, and 70% revenue share
Every plan upgrade is immediate. No waiting, no approval process. Downgrading keeps your characters and data intact — you just lose access to higher-tier features until you upgrade again. See the full plan comparison at dyva.ai/pricing.
