Charisma.ai
Story-driven conversational AI for training simulations and brand campaigns
Overview
A UK conversational-AI platform, from Oxford's Charisma Entertainment, that pairs a visual story editor with generative, emotion-aware character dialogue — once aimed at game studios, now focused on online training simulations and brand campaigns — deployed through web, VR and game-engine SDKs.

Charisma comes at AI dialogue from the writers' room, not the ML lab. Its visual story editor lets designers lay out beats, personalities and emotional arcs, then generative Improvisation produces lines that stay inside those rails — a deliberate hedge against the off-brand rambling pure-LLM characters are prone to. That makes it a better fit for authored experiences than open-ended sandboxes, and the company has leaned into that: it now sells mainly for training simulations and brand campaigns rather than game NPCs. The SDK spread is generous (JavaScript, React, Unity, Unreal, Python, all MIT), though last updated in 2025. Pricing is credit-based — $5 per 50,000 credits, about 200 minutes — with a one-month Pro trial rather than a free tier, and accounts opened through sales. A 2024 Keywords Studios tie-up is unconfirmed today, and the public review trail is thin, so weigh it on a pilot.
What we found
Charisma.ai has moved its focus. It built its name on a visual story editor for game NPCs, but its site now leads with "immersive conversational AI for online training and campaigns", with training and development and brand campaigns as its two use cases; its About page no longer mentions games. The Oxford company, Charisma Entertainment, won Digital Catapult's Responsible and Ethical Tech Pioneer award.
The design reflects narrative control. Designers map story beats, personalities and emotional arcs in a visual editor, then a feature called Improvisation layers generative dialogue on top — available on Pro stories and billed in credits — so characters stay on script rather than drifting like pure-LLM chatbots. Analytics cover playthrough starts and finishes, average time, messages and transcripts.
The developer surface is wide for a company this size: MIT-licensed SDKs for JavaScript, React, Unity, Unreal and Python, so one story can drive a browser, a VR headset or an in-engine character, though they were last updated in 2025. A 2024 announcement had Keywords Studios exploring advisory and implementation services around Charisma; Keywords' current AI pages don't mention it, so treat that partnership as unconfirmed today.
Pricing is credit-based. Pro is pay-as-you-go at $5 per 50,000 credits — about 200 minutes of experience — with bundles up to $500 for five million that expire after 12 months. Enterprise combines a one-off development fee with a fixed monthly platform fee based on usage. There is no permanent free tier, but a Pro licence comes with a one-month trial and 50,000 credits, and accounts are opened by contacting the company rather than by self-serve signup.
The public review trail is thin, so there is little independent data on latency or reliability at scale. Best evaluated with a pilot against a real script, particularly for training simulations and branded experiences.
