Arcade vs Synthesia

Arcade is an interactive demo and product video platform from Arcade Software, founded in early 2021 by former Atlassian colleagues Caroline Clark and Rich Manalang. Its seed round was led by Upfront Ventures with Sequoia and Bond. The original job is simple: record clicks in your product with a browser extension and turn them into a clickable, embeddable walkthrough that prospects can try on a website, blog or social post before signing up.

Today Arcade sells two product lines. Interactive demos add branching, hotspots, AI voiceovers, AI translations, lead forms, CTAs, MP4 and GIF export and engagement insights. AI video builds editable launch videos, changelogs, tutorials and talking-head clips from your product and brand, and can be requested from Claude or ChatGPT through the Arcade MCP. Demo plans run Free, Growth (per seat) and Enterprise; AI video has a separate Free and credit-based Pro plan.

Arcade suits product marketers, sales engineers and growth teams at product-led SaaS companies who want demos live in hours. It is not an in-app onboarding tool like Userflow or Stonly, and async screen recording for internal updates is cheaper in Loom. Custom domains, SSO and the native Salesforce integration sit on Enterprise only.

Buying tip: demo subscriptions do not include AI video credits, and monthly credits do not roll over. Arcade says more than 37,000 teams use it, with logos such as Atlassian, Zapier, Retool and Carta, so check which product line you actually need before buying both.

Synthesia is an AI video generation platform that turns scripts, documents and slides into videos presented by realistic digital avatars. Founded in London in 2017 by a team of entrepreneurs and computer vision researchers, it is one of Europe's best-funded generative AI companies and is used mainly by corporate learning, HR and communications teams to produce training and internal videos without cameras, studios or presenters.

Users pick from a library of stock avatars or create a personal avatar of an employee, write or paste a script, and generate voiceover in more than 140 languages and accents, including Turkish. A slide-based editor with templates, brand kits, screen recordings and media library keeps videos consistent, and one-click translation updates a video for other markets. Enterprise features include SCORM export for learning management systems, collaboration and review, an API, SSO and strong content moderation and security controls. Plans run from a free Basic tier and credit-based Starter and Pro subscriptions to custom Enterprise contracts.

Synthesia fits L&D and enterprise communication teams that need many short, frequently updated videos in several languages. Credit limits on lower plans, a somewhat formal avatar style and its focus on training rather than marketing creative are the main trade-offs. HeyGen is more flexible for marketing and social video, Colossyan targets the same training market, and D-ID suits interactive avatar use cases.
