Thoughtful, observant, and quietly curious.
AI interactive experience studio
Create an experience. See how it plays.
CharFab gives creators a private workspace to build and test AI interactive experiences. Shape characters and scenes, bring your own models, and run text or voice sessions to learn what works.
Invitation-only beta · Bring your own model API · Creator plan planned at $9/month

“You remembered. I was hoping we could pick up where we left off.”
ATest persona
Alex
The version of you this story meets.
Create · run · refine
Prototype the experience, not just the prompt.
Keep characters, scenes, model setup, and private test runs together so you can see how an interaction unfolds and improve it.
Define the character
Shape identity, motivation, personality, behavior, speaking style, voice, and visual direction in one compact profile.
Set the test context
Combine reusable Personas and scenes with any character to probe how it behaves with different people and situations.
Run independent tests
Start multiple sessions with the same setup. Each run stays separate, so experiments do not overwrite one another.
Bring your own models
Connect supported providers and choose separate language models for text chat, low-latency voice, and summaries.
Test text and voice
Review written responses, listen to individual replies, or rehearse with an automatic half-duplex voice call.
Keep work private
Each account receives an isolated workspace. Provider keys are encrypted by the server and are never returned to the browser.
How it works
From first idea to first test run.
Start with the experience you want to explore, then use characters, personas, and scenes to test how it unfolds.
Connect a provider
Add your own provider key and model ID. CharFab validates the connection before enabling it for a test run.
Define the test
Describe the character, choose the Persona they will meet, and add a reusable scene when the situation matters.
Run and refine
Try a private text or voice session, observe the interaction, then revise the setup or start another independent run.
Where CharFab is headed
One creative foundation. More ways to tell a story.
The beta starts with character- and scene-driven text and voice experiments. We are exploring creator workflows for interactive stories, comics, short-form video, and other AI-native experiences. Comic and video creation are future directions, not beta features.
Planned Creator plan
Creator · $9/month
Bring your own model API key. Model and voice-provider usage is billed separately by your provider. CharFab is currently an invitation-only beta; paid Creator subscriptions are not open yet. Plan features and purchase terms will be published before checkout opens.
