One concept per render. Show the action — abstract metaphors confuse video models. For longer explainers, render 8-15 clips and assemble in /video/editor/.
Need narration? After this clip downloads, send the script to /voice/tts/ for the voiceover. Mix in /video/editor/ for the full explainer with subtitles + music.

Explainer videos without the Vyond subscription

Vyond, Powtoon, Animaker, Doodly — every commercial explainer-video tool is template-based with a $19-$89/month subscription. The trade-off: scenes look obviously templated. Free.ai renders an original clip per scene, free, on our GPUs. The trade-off in the other direction: you compose the scenes yourself rather than dragging templates onto a timeline. For a full 60-90 second explainer, render 8-15 short clips here and assemble in /video/editor/ — the same multi-clip workflow professional explainer studios use.

SaaS landing-page hero

Isometric 3D rendering of the product flow. Free.ai gets you the scene; pair with /voice/tts/ + /music/generate/ for a full hero loop.

Educational + course content

Whiteboard style is the educational genre's signature. Render one beat per concept; assemble into a full lecture in your editor.

Pitch-deck videos

Embed an explainer clip into your YC / fundraising deck. Visual variety beats static slides for investor attention retention.

Ad creative

Animated explainer ads on Meta / TikTok / YouTube outperform static creative on click-through. Render multiple variants for A/B testing.

Internal training

Onboarding / compliance / SOP videos. Pair with /voice/tts/ for narration in 174 voices across 37 languages — same pipeline for global teams.

Nonprofit + advocacy

Hand-drawn / 2D character style works well for cause-driven explainers. Free tier means small NGOs do not need a media-house budget to ship a video campaign.

AI Explainer Video — FAQ

Free.ai AI Explainer Video Generator renders a short 2-6 second explainer clip from a concept description. Pick a visual style (whiteboard / motion-graphics / 3D isometric / hand-drawn / corporate / animated icons / infographic), set aspect and duration, and render on our GPUs. Best for illustrating a single abstract concept - the hand-off moment in a tutorial, the "how it works" beat in a pitch, the bridge in a training video.

Yes - self-hosted CogVideoX runs free inside the daily token pool (~7,500 tokens for a 3-second clip). Premium models cost more per clip but render faster with cinema-grade fidelity. Free accounts get 10,000 tokens on signup - enough for several iterations before you need to top up.

Animation focuses on character + motion style (2D / 3D / anime / Pixar-like / claymation). Explainer focuses on information visualization - whiteboard annotations, isometric infographics, animated icons. Overlap is intentional; pick Explainer when your goal is to make a concept clearer, Animation when your goal is a narrative clip with characters.

Vyond ($49-89/mo) is the enterprise explainer-video leader with a character library. Powtoon ($19-99/mo) and Animaker ($10-39/mo) are template-based. Doodly ($20/mo) specializes in whiteboard style. RenderForest ($14-30/mo) is a general video platform. All charge monthly. Free.ai renders a single AI clip for free - not a templated scene library, so you compose the scenes yourself.

2-6 seconds per render. For a full 60-90 second explainer, render 8-15 short clips and stitch them in /video/editor/ or CapCut. This is the same workflow professional explainer studios use - short shots assembled on a timeline, each 2-4 seconds long.

Whiteboard (for tutorial / educational), isometric 3D (for SaaS product explainers), animated icons (for "how it works" steps), infographic (for data storytelling), corporate (for B2B pitches). Hand-drawn lends a human touch; motion-graphics keeps it snappy. Match style to your audience - corporate buyers prefer isometric, education buyers prefer whiteboard.

Name the scene, the one action happening, and the visual language. "Isometric illustration of a server rack, data packets flowing from left to right as glowing blue dots, clean white background" works. Vague prompts ("explain how the cloud works") produce confused output - give the generator a frame to render, not a concept to understand.

Not in the same render - video generation is visual only. After rendering, drop the clip into /video/caption/ for TikTok-style captions, /video/subtitle/ for standard subtitles, or /video/editor/ to add a narration track via our TTS. Full pipeline: render clip here, narrate via /voice/tts/, mix in /video/editor/.

No - AI video is pixel-by-pixel generative. Output varies per render, which is a feature (every scene is unique) and a drawback (consistency across scenes requires careful prompting). Reuse the same prompt structure with modifiers like "same character, now looking right" to maintain visual continuity.

The UI + prompts support all 99 Free.ai languages. Video models themselves are trained mostly on English captions, so English or translated-to-English prompts produce the best output. Non-English text on screen (if you prompted "Japanese text on signage") renders as lookalike characters, not real readable text - bake text overlays in post.

Yes - POST /v1/video/generate/ on api.free.ai. Same endpoint as /video/, with explainer-tuned prompts composed client-side. Bearer auth, monthly limits. See /api/ for snippets.

Yes but budget accordingly - 100 explainer clips at 3 s each ~ 750K tokens ~ $3.75 at $5 = 200K-token top-up pricing. Use the /batch/ queue to run overnight if you need 100+ clips without sitting at the keyboard.
