CustomCharisma.ai's PRO plan is pay-as-you-go and built for developers using Charisma's SDKs on smaller bespoke projects, priced at $5 per 50,000 credits, roughly equivalent to 200 minutes of experience runtime. It includes access to the SDKs, story collaboration and script flow tools, speech-to-text, the AI voice library, custom voice integration, additional languages, and generative AI dialogue features.
There is no separate mid-tier plan; organizations with higher usage needs or that require a fully built experience move to the Enterprise tier. Enterprise pricing combines a one-off development fee tailored to the project (covering front-end build for web, mobile, app, game, or VR, visual design, script-writing, and technical support) with a fixed monthly platform fee based on estimated usage.
Enterprise plans include everything in PRO plus additional premium AI voices, admin-only platform tools, a user management system, a dedicated account manager, and access to Training & Development templates. Exact Enterprise pricing requires contacting Charisma's sales team directly.
FreemiumFree – $0: Create AI videos with limited credits, basic avatars, and core video generation features.
Creator – $24/month: More video credits, premium avatars, faster video creation, and no watermarks. Great for individual creators.
Team – $69/month (per seat): Designed for teams with collaboration tools, brand kits, higher limits, and shared workspaces.
Enterprise – Custom Pricing: Custom avatars, advanced security, API access, SSO, dedicated support, and scalable solutions for large organizations.
