Invite-only preview

Ad creatives, directed by AI.

Bistellar turns your ad copy into expressive voiceovers. An AI director marks every line with emotion, pacing and vocal sounds. Your team fine-tunes the delivery with a click and generates as many takes as it needs.

AI direction

Paste your copy and describe the mood. Bistellar decides how each line should be read, and explains why.

Human control

Change any emotion, pace, pause or laugh in place. Every take keeps its exact script, so you can compare and restore.

Brand voices

Pick from a voice library or design a voice that belongs only to your brand, from a short description.

Built for agents

Everything in the app is also available over a REST API and MCP, so AI agents can make creatives for your team.

Video and templates are next.

Bistellar is in private preview with a small group of teams. Tell us what you're making.
