AI Explainer Videos

Give it a document or an idea and get a narrated explainer back, with the visuals built to match what the narration is saying.

AI explainer video maker: from a topic or PDF to a narrated video

Type a topic or attach a PDF, such as a paper, report, guide or lesson, and get a narrated explainer video. The script is written for you, matching visuals are generated for each part of the narration, and captions are burned in.

Make anything from a 10-second teaser to a 10-minute lesson, in landscape 16:9 or vertical 9:16, with your choice of six narrator voices and any of the caption styles from the Captions page.

How it works

Give it a topic or a PDF. Describe what to explain in up to 1,000 characters, or attach a PDF of up to 15 MB and the video teaches its content.
Choose the length and shape. From 10 seconds to 10 minutes, in 16:9 or 9:16.
Pick a voice and caption style. Preview the narrator voices and choose how the captions look.
Generate. Get an MP4 with script, visuals, narration and captions, ready to download or edit.

Questions

Can it make a video from a PDF?

Yes. Attach a PDF of up to 15 MB and the explainer teaches its content. A topic is then optional and only sets the focus.

How long can the video be?

10 seconds, 15 seconds, 30 seconds, or 1, 2, 3, 5 or 10 minutes.

Do I need to write the script?

No. The script is written from your topic or PDF, then narrated and illustrated automatically.

Can I make vertical videos for TikTok and Reels?

Yes. Choose 9:16 Vertical, or 16:9 Landscape for YouTube and presentations.

Does the video have captions?

Yes. Captions are burned in, in the caption style you choose.

How much does an explainer cost?

The price in credits is shown on the Generate button and grows with the length of the video.

Tools

AI Writing — Draft scripts, captions, ad copy and prompts with frontier models, then send the result straight into an image or video generation.

AI Image Generator — Turn a prompt into an image with more than a dozen AI models. Auto picks the right one for the shot and tells you what it costs before you press go.

AI Video Generator — Turn text or an image into video, up to 4K and 30 seconds on supported models. Pick a model, or let Auto weigh quality, speed and price for you.

Video Editor — A full timeline for video, images and audio — trim, layer, add music, generate subtitles and render out, with your AI generations already in the library.

Templates — Start from a build that already works. Prompts and settings prefilled for ads, reels, product shots and more — change the subject, keep the look.

AI Video Transitions — Upload two or more scenes, pictures or videos, and generate a clip that moves from the last frame of one into the first frame of the next, as a fade, wipe, morph, dissolve, zoom or slide.

Extend Video — Carry a clip past where it stopped. The model reads the last seconds and keeps the motion, the lighting and the subject going.

Face & Object Swap — Put a different face or object into a shot you have already made, and keep the lighting and the angle it was lit for.

Image Fusion — Blend two images into one — a subject into a scene, a style onto a photograph — without losing what made either of them work.

AI Sound Effects & Audio — Generate sound effects, ambient beds and voiceovers from a description, then drop them onto the timeline next to the picture.

AI Voiceover & Text to Speech — Turn a script into a voiceover in a voice you choose, with control over stability and delivery, ready to lay under a cut.

AI Lip Sync — Match a face to an audio track so the mouth actually says the words — for a voiceover you generated or one you recorded.

AI Outpaint — Expand Photos — Widen a photo past its edges: pick a new shape or zoom out, and the scenery that was never in frame is painted in to match.

AI Relight — Change Photo Lighting — Light a photo again after it was taken — golden hour, studio softbox, neon night — from the side you choose, with the subject left as it is.

Restyle Video — Repaint a clip in another style — animation, illustration, film stock — while the motion underneath it stays exactly as shot.

Shorts & Reels Maker — Cut a long video into vertical shorts. It finds the moments worth keeping, reframes to 9:16 and burns in captions.

Auto Captions & Subtitles — Transcribe a video with AI and burn in styled captions that are legible with the sound off, which is how most of it will be watched.

AI Director — One sentence in, a whole production out: script, shot list, prompts for every shot, transitions, captions, music direction and the aspect ratio to cut for.

Consistent AI Characters — Build a character once and keep the same face across every image and video you generate afterwards.

AI Fashion & Virtual Try-On — Put a garment on a model you choose, in the pose and setting you want, from a product photo and a prompt.

Sports Broadcast Graphics — Generate broadcast-style sports packages — titles, replays and lower thirds — from a clip and a scoreline.

AI Upscaler & Quality Enhancer — Take an image or a video up to 2K or 4K, and get back detail that compression and a small sensor took out.

Background Remover — Cut the subject out of an image or a video automatically — clean edges, transparent background, no rotoscoping.

AI Video Translator — Translate a video into another language and keep the speaker's voice, with the lips matched to the new track. Twenty languages.

Quick Edit — Trim, crop, reframe and caption a clip in a few clicks, without opening the full timeline.

AI Architecture Renders — Turn a sketch, a plan or a massing model into a photographic render, in the light and materials you specify.

AI Avatar — Build a presenter that looks like you, or like nobody, and have it deliver any script you write.

AI Influencer — Design an AI influencer trait by trait, or start from your own photo, then make it copy the moves of any video or wear your products.

Bulk Repurpose — Point it at a video and get every platform's cut at once — vertical, square, captioned, sized and ready to schedule.

Schedule — Drop in up to a hundred videos, stamp your watermark on all of them, and schedule them across your channels in one go.

Motion Control — Move the camera on purpose — recast a performance, puppeteer a still, or transfer motion from one clip onto another.

AI Ad Builder — Turn a product and a promise into a finished ad — the script, the shots, the voiceover and the cut, sized for where it runs.

AI App Builder — Describe a website, an app or a browser game and get working code you can open, edit and publish from here.

Super Intelligence — One place to ask for anything the studio can make. It plans the work, picks the models, runs the steps and shows you why it chose each one.

MCP Server — Connect SohaAI Studio to Claude, Claude Code or any MCP client and generate images, video, audio and lip sync from inside your own tools.
