About Charisma.ai
Charisma.ai is a UK-based conversational AI platform for building immersive, voice-enabled character experiences used in corporate training, brand campaigns, and interactive entertainment. Founded in 2017 by CEO Guy Gadney and co-founder Ben Salili-James, the company has built projects for Warner Bros, Sky, BBC, DreamWorks, and Oxford University, and won the DigitalCatapult Responsible and Ethical Tech Pioneer Award.
The platform's core is a visual, node-based story graph editor where creators connect character, action, memory, and generative AI nodes to script branching conversations, blending human-authored dialogue with generative AI in any mix they choose. Built-in speech-to-text, an AI voice library, and real-time KPI analytics let teams measure engagement, while SDKs and Plug 'n' Play integrations for Unity and Unreal Engine allow experiences to run on web, mobile, VR, and game engines.
Charisma.ai is built for L&D teams, brand marketers, museums, and game studios that want realistic, on-message conversational simulations rather than generic multiple-choice branching content.

Cons

Pricing
Charisma.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.
