AI-powered creation, made for learning
GroutFilm pairs on-device AI generation with a full multi-track editor so students and teachers can create videos and audio for the classroom. Generate, caption, and edit — every model and render runs locally, and nothing is ever uploaded.
AI-Powered Creation
Generate video, audio, images, voiceovers, and music with on-device and industry-leading models — then edit them on a real multi-track timeline.
Made for the Classroom
Built so students and teachers can create AI-powered videos and audio for learning — storytelling, lessons, and projects without a steep learning curve.
Local-First & Private
No uploads and no cloud lock-in. Projects and media stay as plain files on the device, so classroom work stays private and portable.
Generate, edit, and finish — all in one app
From AI video, audio, and image generation to a multi-track timeline, GPU effects, and keyframe animation — GroutFilm is a complete creation studio for learning.
AI Video & Audio Generation
Generate video and audio clips with industry-leading generation models — right inside the timeline. Describe a shot, get a draft, then refine it.
Image Generation Models
Create images from text prompts with built-in image models, then drop them straight onto the canvas as clips, overlays, or backgrounds.
Inline AI Tools
Browser Whisper transcription, AI captioning with local vision-language models, and scene detection that turns footage into searchable, captioned moments.
Offline Speech & Music
Local Kokoro text-to-speech voiceovers and MusicGen music generation with presets and progress — no internet, no accounts, no per-render cost.
Multi-Track Timeline
Video, audio, text, image, shape, and mask tracks with split, ripple, slip, slide, and rate-stretch tools, snap guides, markers, and frame-accurate playback.
Effects, Transitions & Keyframes
WebGPU effects, 25 blend modes, chroma key, masks, a full transition library, and a bezier keyframe graph editor with easing presets.
Local-First & Private
No uploads. Projects, media, generated assets, transcripts, and caches live as plain files inside a workspace folder you pick — safe for student work.
