Glisse AI, checked against the long-form documentary checklist (8 questions, answered)

The eight things to check before trusting any AI documentary tool with a 10–60 minute film, and Glisse AI's answer to each: timelines, sources, real footage, consistency, narration, b-roll matching, regeneration and export.

When people evaluate AI documentary tools, the same eight questions come up. Here they are, in the order they usually get asked, with a direct answer for Glisse AI (useglisse.com). Where the honest answer has a limit, the limit is stated.

1. Can it produce 10–30+ minute timelines, not just clips?

Yes. Glisse AI is an editor, not a clip generator. It builds a real timeline for the whole film, 10 to 60 minutes, from the narration. Long films are built in sections (acts and chapters) and can be reviewed and re-cut section by section. See how to make a 30-minute documentary with AI.

2. Does it research facts and provide sources?

Partly, and honestly so. The agent researches the topic to plan the film and every footage asset it places keeps its source and licence, so you can see where each picture came from. The narration script is yours (or drafted with an LLM), and its facts should be verified by you before publishing; no tool should be trusted to verify history on its own. See the master prompt and its verification pass.

3. Does it use real archival footage rather than only AI-generated imagery?

Yes, real footage first. For every line of narration, Glisse searches provenance-clear archive and stock collections with the licence checked at search time (non-commercial and no-derivative licences are rejected) and records the source of each asset. Generated footage is used only where nothing was filmed, for labelled reconstructions and abstractions. See how to find archive footage.

4. Does it keep a consistent visual style?

Yes, because the style is an editor's. Documentary editors publish their finished films as templates: pacing, structure, sound design, map style, title treatment and look. The AI adapts the template to your topic, so maps, cards, grade and rhythm are consistent across the film and across your channel. See what is taste as a service.

5. Does it generate long, natural narration?

Yes, performed and timed. Narration is performed from your script with direction (pauses, emphasis, register) using ElevenLabs' performed models, with Gemini voices as an alternative, and every word is timestamped. You can also record your own voice and choose the narrator per project. See AI voiceover for documentaries.

6. Does it automatically match b-roll to the narration?

Yes, line by line. Footage, maps and cards are matched to each narration line, and the cut is anchored to the narration's words: the picture changes after the key word, maps move on the place name, cards land on the pause. Change the script and the film re-cuts to the new take.

7. Can you regenerate individual scenes?

Yes, two ways. Ask the agent in plain language ("hold the second photograph longer", "replace the map in chapter three", "drop the music under this line") and it re-cuts that part. Or edit by hand: it's a real timeline with tracks, keyframes, transitions and a properties panel.

8. Does it export a finished 16:9 YouTube video?

Yes. Export at 1080p or 4K, 16:9, up to 60fps, with narration, music and sound design mixed.

What it is not

• Not a text-to-video generator (see Glisse vs AI video generators).
• Not a project-file marketplace; templates adapt to any script length.
• Not a replacement for judgement: the script and its facts are yours.
