One topic to a full-length documentary
Turn a subject into a full documentary without a film crew. Long Story's AI documentary maker writes an authoritative, chaptered narration, voices it in a documentary tone, generates matching visuals, and renders the finished film — built for history, science, and true-story deep-dives.
A chaptered, well-paced documentary script in a serious, narrated tone — not generic filler.
Scene imagery generated to fit the narration, in the aspect ratio your platform needs.
Render documentaries that run for hours without audio drift or dead air at the end.
Enter a topic (or your own script) and choose a documentary tone and length.
Long Story produces the narration, voiceover, and scene visuals as one job.
Download the finished documentary with chapters and metadata, ready to upload.
Yes. Use the script tool to generate one, or bring your own and send it straight to voiceover and render.
History, science, true crime, mysteries, and explainer deep-dives — anything narration-led that benefits from a documentary tone.
Up to 10 hours, rendered clean to the final second — Long Story is built specifically for long-form.
Why Long Story
1 to 10 hours, rendered clean to the final second — no audio drift, no black frames, no silence at the tail, the place long videos usually fail.
Script, voiceover, visuals, and render run as a single automated job you can watch move — no stitching tools together by hand.
Credits, not a subscription. One credit makes one video — a 10-minute clip or a 10-hour render cost the same single credit.
Download the finished file and own it. Voice cloning is consent-gated, and your topics and renders stay yours.
