Synthesia

Synthesia pays 25% of net customer payments for twelve months from the first purchase, with a 60-day attribution window and a low $30 minimum. Payouts land in the first five business days of each month.

What you're promoting

Synthesia turns a script into a video with an AI presenter, in over a hundred languages. Its centre of gravity is corporate: onboarding, compliance training, product explainers and internal comms, where the alternative is a film crew and a studio day.

That enterprise lean matters to you. Plans start modestly for individuals but the real revenue is in team and enterprise contracts, and 25% of those is a meaningful number.

The commission, and why it beats the flashier rates

Twelve months at 25% is roughly two and a half times what HeyGen's 35%-for-three-months pays over a customer's first year. Headline rates in AI video are frequently short-duration, and comparing them without the duration attached is how affiliates end up disappointed.

The $30 threshold is genuinely low for an enterprise-focused tool, which means a small site reaches payout on its first or second conversion rather than waiting a year.

Who converts

L&D managers, internal comms teams, agencies producing training content, and course creators who need volume without filming. Content that works: localisation and translation workflows, cost comparisons against traditional video production, and honest assessments of where avatar video is and isn't appropriate.

Entertainment and social-first creators convert poorly. Synthesia's avatars read as corporate presenters, which is a feature for training and a liability for a TikTok audience.

Synthesia vs HeyGen

Synthesia wins on duration, attribution, threshold and, decisively for most publishers, on accepting written promotion at all. HeyGen's higher rate is the only column it takes.

Getting approved

Apply at synthesia.io/partners/affiliates. Approval favours sites with business, L&D or video production content. There's also a separate reseller and partner track if you implement for clients rather than writing about it.

Verdict

The best AI video program for written affiliate sites, mainly because most of its competitors either cap commissions at three months or refuse blog promotion outright. Target corporate training and localisation buyers rather than social creators, and use the low threshold to get paid early.
