Open with the problem
Use the first sentence to name the question, task, or product benefit. A concrete opening gives the first image a clear purpose.

How to use
Enter a script, choose the visual source, generate the video, check the preview, and download it.
Paste the full narration. Choose a landscape, vertical, or square ratio, then select the voice.
Leave Images empty if you want AI-generated visuals. Open Images and add your files before generating if you want to use your own visuals.
Select Generate a video once. Wait while NarraCut creates the voice, timing, and visuals. The button remains locked until the video is ready.
Play the video from start to finish. If you uploaded images, select part of the script to replace the image shown for those words. Open Settings to change the ratio or animation.
Select Download MP4 to export the current preview. Use Create new video when you want to begin with a blank draft.
Bring the script and visuals. NarraCut creates the voiceover, caption timeline, visual timing, live preview, and downloadable MP4.
NarraCut uses the generated voiceover as the timing source for the whole composition. Captions follow the spoken words, images follow the meaning of each section, and the canvas adapts to the publishing ratio you select.
Preview the full result, switch between landscape, vertical, and square formats in real time, then export the current composition as an H.264 MP4 in the browser.

A useful explainer answers a specific question. Plan the narration around what the viewer needs to understand or do next.
Use the first sentence to name the question, task, or product benefit. A concrete opening gives the first image a clear purpose.
Pair a product feature with its screenshot, a process with its diagram, or a lesson with its example. Review image assignments after generation and replace visuals that do not explain the spoken point.

Start with the material you have: a script, pictures, or an existing video.
Match your screenshots, photos, and diagrams to specific passages of narration.
Turn one image into an animated line drawing with a progressive color reveal.
Add independently timed AI narration and subtitles to footage you already have.

Place titles, labels, lower thirds, or text watermarks on an existing clip.
FAQs
NarraCut turns a script and a set of images into a narrated video. It generates the voiceover, creates word-level caption timing, matches each visual to the most relevant part of the narration, and assembles a preview that can be exported as an MP4.
A script is enough to begin. You can paste finished narration, use AI writing to create a draft from a topic, upload your own screenshots or images, or ask NarraCut to generate a visual set. Your own script and visuals always remain the source material for the final cut.
NarraCut transcribes the generated voiceover into a word-level timeline, analyzes the supplied images, and assigns each image to the section of narration it best supports. If semantic matching is unavailable, the visuals are placed in their original order so the video can still be completed.
Yes. Upload existing product images, diagrams, screenshots, illustrations, or photos, and arrange them in the image panel. You can also generate a visual set with AI by choosing the number of images and a style such as editorial, photorealistic, illustration, 3D, or minimal.
NarraCut previews and exports MP4 video in 16:9, 9:16, and 1:1. Switching the ratio updates the current composition immediately, so the same narration and visuals can be prepared for landscape, vertical, or square publishing.
