Synthesys is an AI video agent aimed at marketing teams. Instead of working in an editing timeline, a user describes the video they want through a prompt, script, product link or image, and the agent produces a finished file. The platform covers ads, UGC-style content, commercials, explainers, training videos and voiceovers.
The company was founded in London in 2020 by Nick Koukoulakis and began with AI voice generation before adding avatars, language expansion and multi-model video generation. It states that it has produced over 1,000,000 videos for more than 50,000 creators and businesses.
Its logo wall includes Coca-Cola, Yahoo, TCS, AT&S, Heat and Control and Jetex. The site also shows ratings of 4.4 on Trustpilot, 4.6 on Capterra, 4.7 on G2 and 4.6 on Software Advice, which are company-reported figures.
The workflow has three steps. First, the user picks a format and style, such as a UGC ad, product video, AI avatar video or video sales letter, from a template or from scratch. Second, the user adds a script, a product link or a brief, and the agent can generate the rest.
Behind the scenes, Synthesys analyzes the input and routes it to what it considers the best-suited model. The about page names Sora 2 for cinematic motion, Google VEO 3.1 for photorealistic output, Kling 3 for complex movement and Wan 2.5 for rapid iteration.
Users review the script and storyboard before spending credits, preview the result and download an MP4. The app quotes the credit cost of each video before approval, and failed generations are not charged.
The agent supports 11 formats: UGC ads, TV commercials, animation stories, faceless stories, TikTok shorts, app promos, explainers, presentation videos, presenter videos for YouTube and TikTok, sales videos and video restyling. Inputs include chat briefs, product pages, competitor ad URLs and uploaded footage.
Studio tools add image generation with 12 models, video clips of up to 30 seconds with start and end frames, and a voiceover studio with 20 narrators. The site also lists 400+ voices and dubbing into 140+ languages with lip-sync.
Higher plans add workflow features. Pro includes Brand Kit for logos, colors, products and end cards. Agency adds a winning video ads library with competitor tracking and publishing or scheduling to TikTok, Instagram and Facebook. Output runs from 480p to 4K across four aspect ratios.
