Power conversational characters with Charisma

Charisma is a platform for creating interactive stories with believable virtual characters. Using our dialogue engine, players and audiences can meet them, converse with them, and change the story.

What is Charisma?

Charisma is an easy, no-code way to create interactive stories with believable virtual characters that respond to what you say.

Unlike chatbot platforms, Charisma uses the language of storytelling, with built-in features like emotion, memory, scenes and subplots to make your stories feel alive and delightful.

By creating branching narratives powered by the latest advances in natural language processing technology, youʼll help your audiences feel a stronger connection with their favourite characters.

Using Charisma for Bulletproof Interactive


Let your characterʼs personalities shine through and have their feelings influence their reactions. Play with love, hate, and everything between to make key moments memorable and replayable.


Characters can remember decisions, information about the player, and even playerʼs sentences to quote back later in the story. Like emotions, memories can change how the story plays out, making experiences feel alive and influenceable.


Charisma supports a wide range of state-of-the-art voices for characters with out-the-box support for lifelike performance. Characters arenʼt the only ones with a voice either. Your audiences can speak to Charisma characters too using speech recognition.

Natural Language

If you can write English, then you can write into Charisma. Thereʼs no special syntax to learn. Instead, Charisma uses the latest machine learning tech to make authoring stories fast and simple.


Whether youʼre writing a dramatic soliloquy with a single character or you have a large cast of characters, Charisma supports contextual interaction with each other to perform engaging drama.


Charisma tracks conversations in real-time and has analytics dead-centre in the story editor, so you can write more of the storylines that players are enjoying, and fine-tune the ones that arenʼt, keeping your audiences interested and happy.

Ready to use in your projects

With integrations into Unreal Engine, Unity, JavaScript, React, React Native (for iOS and Android) and Python, having interactive characters is a step away.
