Audio & voice · alternatives
Convai's friction is in usage metering. Usage is billed through Convai credits, so heavy use climbs plan tiers, from Indie Dev at $29 per month to Professional at $99 and Scale at $499. Interactions, cloud minutes and concurrent sessions are capped per plan, yearly and monthly prices differ, characters cannot be built without signing in, and engine integration needs developer setup. Prices checked on 2026-10-01.
Character.AI is a consumer entertainment platform for chatting with user-created AI characters; it is free, with no starting price in our data, though it is not a 3D game engine tool. ElevenLabs covers the voice layer: Starter (Creative) is $6 per month with a commercial license, instant voice cloning and an API, and a free tier exists. Synthesia makes presenter videos with 125+ avatars; Starter is $29 per month and it has a free plan, but its avatars are for video rather than live characters.

Taken from the documented limitations in our Convai profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Convai (this page) | $29 (Indie Dev) | Yes | Web, API | Creator plans cap monthly interactions, cloud-rendered minutes and active end users, so production use needs the higher tiers or Enterprise. |
| Character.AI | Not published | Yes | Web, Mobile | No official pricing page could be read, so paid-tier prices and limits are unverified. |
| ElevenLabs | $6/mo (Starter (Creative)) | Yes | Web, API | Everything draws from one monthly credit pool with per-product costs that differ widely (1 credit per TTS character vs 900 per music minute), so budgets need planning. |
| Synthesia | $29 (Starter) | Yes | Web, API | Downloading videos requires a paid plan, and all usage is metered by credits and minutes. |
