OpenMontage

OpenMontage is a speech (TTS/STT) tool - World's first open-source, agentic video production system. 12 production pipelines, 100+ tools, 700+ agent skill and production-knowledge files. Turn your AI coding assistant into a full video production studio.

Overview

Bloome lets multiple AI agents (Claude, ChatGPT, DeepSeek, and more) collaborate in one conversation for agentic video pipelines. It has zero setup, runs in the cloud, works on web and mobile, and lets you share a configured agent with your whole team. Try Bloome .

Atlas Cloud is a full-modal AI inference platform that gives developers a single AI API for video generation, image generation, and LLM APIs. Instead of managing multiple vendor integrations, you connect once and get unified access to 300+ curated models across all modalities. Check out Atlas Cloud's new coding plan promotion for more budget-friendly API access.

Turn your AI coding assistant into a full video production studio. Describe what you want in plain language — your agent handles research, scripting, asset generation, editing, and final composition.

Important distinction: OpenMontage can make image-based videos, but it can also make a real video video for free/open-source workflows: the agent builds a corpus from free stock footage and open archives, retrieves actual motion clips, edits them into a timeline, and renders a finished piece. That is not the usual "animate a handful of stills and call it video" trick.

OpenMontage is open-source, written primarily in Python, with 62,035 GitHub stars under the AGPL-3.0 license. It was last updated on 2026-09-06.

Key capabilities

From the project's documentation:

• What it keeps from the reference: pacing, hook style, structure, tone
• What it changes: topic, visual treatment, angle, narration approach
• What it will cost at your target duration, before asset generation starts
• What it will actually look like with your currently available tools
• Python 3.10+ — python.org
• FFmpeg — brew install ffmpeg / sudo apt install ffmpeg / ffmpeg.org

Install

A quick way to get started (always check the official docs for the latest):

pip install -r requirements.txt && cd remotion-composer && npm install && cd .. && python -m pip install piper-tts && cp .env.example .env

How it fits a local-AI stack

OpenMontage runs on your own hardware, so pair it with a model and a GPU sized to your needs. Use the VRAM calculator to pick a model that fits your card, and see what you can run for hardware guidance. Related speech (TTS/STT) tools in the directory:
