Synthesia launches Syren AI video agent with 2,000 free credits for a month
What happened
Between the Oct 9, 2026 and Oct 10, 2026 captures of Synthesia's pricing page, Pulse recorded one change: Syren, Synthesia's AI video agent, added as a NEW feature with a comparison-table section (access, promo credits of 2,000 credits for 1 month, limited time) across all plans. Pulse files it as a product change (feature added) with an upward direction. Pulse's latest capture (Nov 2, 2026) lists Starter at $14 and Pro at $59.
It lands 8 days after Synthesia's previous change, "Synthesia moves to credits, cuts free plan allowance by 58% to 500 a month" (Oct 2, 2026). Before that Pulse recorded "Synthesia slashes Basic plan's AI video assets from 25/mo to just 3" (Sep 28, 2026), "Synthesia decouples AI Dubbing, boosts Starter/Creator allowances up to 5x" (Sep 8, 2026) and "Synthesia quadruples AI Dubbing minutes on Starter and Creator plans" (Sep 4, 2026). Synthesia has been tracked since 2024-11-16.
In the same window Runway, Loom, OpusClip and Descript also changed their AI & Machine Learning pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
