OpenMontage

OpenMontage turns a brief and source materials into an editable video. Its pipeline researches the topic, writes a script, creates a scene plan, narrates, selects or generates media, composes, captions, renders, and reviews the result.

It is designed for teams producing launch videos, product explainers, and other structured video content. The workflow can use a user's own assets, libraries, stock media, or generated images and clips, with scene-by-scene proposals that can be revised.

A review gate shows estimated costs before premium media or narration is purchased. The site describes OpenMontage as open source and says it runs with OpenMontage Studio, Claude Code, ChatGPT Codex, and OpenCode. The product currently invites users to join a waitlist.
