Free Marketing Video Maker

Start by choosing how you want to begin: describe your video in a prompt, paste a script you already have, or upload a file like a PDF, PowerPoint, or Word document. Assistant turns that into a script, scenes, and visuals, then shows you an editable outline before it generates anything. From there you refine the script and visuals by chatting in plain language, add an AI avatar and voiceover, brand it, and download or share the finished video. No cameras, actors, or editing experience needed.

Yes, you can create a marketing video for free, with no credit card required. The free video lets you try the full flow: type a prompt or paste a script, pick an avatar, and generate a real video with an AI voiceover. Paid plans start at Starter and add more minutes, avatars, and features when you are ready to make videos regularly.

The best tool depends on what you are making, but Synthesia is built for business video at scale, with 240+ avatars, AI voiceovers in 140+ languages, and 60+ editable templates. It is rated 4.7 out of 5 from more than 2,000 reviews on G2, and it is used by over 50,000 companies. For marketing teams, the draw is speed and reuse: write once, generate in minutes, then update the same video and reshare without re-recording anything.

You can upload PDF, PowerPoint (.ppt, .pptx), and Word (.doc, .docx) documents, plus plain text (.txt) files, up to 10MB each. You can also add a URL to a public article or blog post, or combine files, links, and a prompt in one request. Assistant reads your source material and writes a fresh script from it, so a deck or a doc becomes a starting point rather than a word-for-word transcript. Documents over 4,500 words are not supported, so trim longer source material first.

A single Synthesia video can run up to 4 hours in total, with a maximum of 150 scenes and up to 5 minutes per scene, whichever limit you reach first. For marketing, shorter usually works better, and when you generate with Assistant you can set the length to Short, Medium, or Long, then tighten it further by asking it to make scenes snappier.

Yes, Synthesia supports 140+ languages and accents, so you can generate the same marketing video for different regions without recording new audio. You choose from 2,000+ AI voices, add captions during setup, and pair a voice with an avatar for a consistent presenter across every version. Full 1-Click Translation of the script and on-screen text is available on Enterprise plans.

Yes. Avatar Builder lets you create custom avatars in animated and stylized looks, from Anime and Comics to Claymation and illustrated 2D or 3D, plus mascots and other non-human characters. You can also pick from 240+ realistic avatars, generate B-roll and motion graphics with the latest AI video models, and animate text, shapes, and images in the editor. It is avatar-led video rather than hand-drawn cartoon animation, but the range of styles is wide.

Once your video is ready, you can download it as an MP4 in up to Full HD 1080p, create a shareable link, or copy an embed code to add it to a landing page or blog. You then share that file or link wherever you need it, on social platforms, in email, or on your site. If you re-edit a shared video, the link and embed update to your latest version automatically, while a downloaded MP4 needs to be re-downloaded and replaced.

No. The prompts you send to Assistant are not used to train models, and your conversations with Assistant stay private to you, not shared with other people in your workspace. Prompts are retained for up to 30 days for abuse monitoring, then deleted unless the law requires otherwise. Synthesia is SOC 2 and GDPR compliant, which is why over 50,000 companies use it for business content.
