Drop a voiceover; we transcribe it into timestamped lines.

Turn any voiceover into an illustrated story video
Make faceless YouTube videos from a voiceover — no camera, no face needed. Drop in an audio narration or record your own. StoryAnimator transcribes it into timestamped sentences, generates one consistent image per line, and lays it onto a real editing timeline synced to the waveform — ready to export as MP4.

Captions come from your timestamped transcript and stay in sync with each shot — no manual timing needed.
Import
Rebuild a video from existing assets — no regeneration. Three ways in:
① Video — split into frames + audiomp4, mov, webm
Splits the video into shot frames and lays its audio underneath. Leave Frames blank to auto-pick (~1 every 3s).
② Frames onlytimestamp filenames (e.g. 049.png)
Each frame is timed from its filename (the timestamp). Pair with a soundtrack below.
③ Soundtrack / audiomp3, wav, m4a…
Sits in the audio track underneath the frames. No re-transcription.
Reconstruct the project (reverse pipeline)subtitles + name + style
Transcribes the imported soundtrack, writes a caption onto each frame by its timing, and drafts the project name (if none), visual style, character bible, intro/outro & thumbnail — the reverse of the normal pipeline.

history.log
Projects are saved automatically when you generate images — and updated whenever you re-roll a still or re-animate a shot, so this always shows your latest version.
StoryAnimator works in Firefox, but Chrome or Edge export faster — Firefox has to download a one-off 30 MB audio encoder on your first export.

Generate a voiceover
Paste your script and pick a voice — we'll narrate it and turn it into a story video. Charged in credits by length.
Pronunciation fixes (optional)Persian doesn't write short vowels, so a name or uncommon word can be guessed wrong. Say it here once and every voiceover in this project follows it.
0 / 5000
Pick a voice and paste a script to begin.
Add 1–3 clear samples (one speaker, no background music or noise) — upload files or record live. Long files are trimmed to the first 2 minutes; that is all cloning needs. Cloning creates a custom voice you can narrate with; the credit cost is shown on the button.

How to get the best results
Voice — audio & script.Start from your own recording (WAV/MP3/M4A), record straight into the browser, or generate an AI voiceover. Whichever you pick, the audio is transcribed into timestamped lines — and every line becomes one shot. Fix any wording in the transcript, and use the “How many images?” slider to set how many shots the story splits into: more shots = shorter, snappier frames.
Look — style & cast.Pick the art style from the dropdown — that one choice owns the look of every frame. The visual-style and character notes are drafted for you and describe mood, palette and who your characters are; edit them freely. For any character you can generate a portrait or upload your own reference photo — the photo is read by AI, the description updates to match (skin tone, hair, wardrobe), and that identity carries through every shot.
Storyboard — prompts & generate.Each card shows a short editable “what to draw” line plus the caption that will appear on screen. Editing here is free — editing before you generate is what saves credits. Then hit Generate. Afterwards you can re-roll a single frame, upload your own image for one shot (upload icon), or bulk-upload a folder (UPLOAD button next to ZIP) to fill every shot in order. Right-click a frame for delete / cut / copy / paste. Animate is optional — shots that are already animated aren’t charged again.
Edit & publish.The timeline auto-syncs each frame to your waveform. Add intro/ending cards (auto-written for you), then export MP4. Your browser encodes it as fast as your machine allows, keeping animation, transitions, cards and subtitles. Browsers without that encoder fall back to recording in real time — there the ⚡ Fast export tick offers a quicker stills-only route (no animation, transitions or cards). Your YouTube title, description, tags and thumbnail are drafted from the narration, ready to copy.
Back up — download what you make.Treat the app as a workspace, not a vault: download your assets as you go and keep your own copy. Every shot has a download button (the clip if animated, otherwise the still), ZIP grabs all frames at once, the voiceover and the thumbnail each have their own download, and ⤓ Extract in History packs the whole project — media, audio and text — into a .zip you own. That .zip can be re-imported here any time, and anything you’ve downloaded can always be re-uploaded: your own audio, a reference photo, a single frame, or a whole folder of images.
History — one project at a time.Your project saves automatically as you generate, re-roll and re-animate, so History always holds your latest version — though only your most recent project is kept. Starting a new one takes its place, so run ⤓ Extract first whenever you’d like to keep the old one. As a matter of good practice, we recommend downloading anything you’re happy with as you go: a copy on your own machine is yours permanently, independent of your account or connection, and can be re-imported or re-uploaded here at any time. You can also re-import a project .zip, or switch History off from the History tab, which clears what’s stored there.
Tip: editing prompts before generating saves credits, and re-rolling or uploading lets you fix any single frame without redoing the whole set — and extract a .zip backup before you start anything new.
