Synthesia Syren
Skip it (for most of us)
Impressive, but too pricey for hobby use.
What it does
You type a prompt and it makes a finished video, with motion graphics, AI avatars, voiceover and music. Then you fix it by chatting with it.
Who it's for
Marketing teams and companies. Synthesia itself calls it a tool for "enterprise video."
Pricing
Uses credits. Synthesia says a 1-minute video usually takes 1,000–2,000 credits. The free plan gives you 500 credits a month (plus launch credits for your first video), and Starter is $29/mo for 1,250.
