Signal Loom — node-based AI media studio with a built-in timeline editor (open source, AGPL)

I built Signal Loom because I was tired of generating assets in one tool and then exporting/importing into another just to edit them. It's a node-based workflow canvas (React Flow) for chaining generative AI tasks - text, image, video, audio - connected to your own API keys (Gemini, OpenAI, ElevenLabs, Hugging Face). Downstream nodes automatically consume upstream context. When you're done generating, you switch to a timeline editor: multi-track, keyframes, cuts, opacity, transform, volume, text overlays, shape layers. Render with FFmpeg. One file, no cloud lock-in.
