Pricing: What You Actually Get

Monthly Cost for Real Usage

Tool	Entry Paid	Mid Plan	Enterprise
HeyGen	$29/mo (Creator — 600 credits)	$49/mo (Pro — 1,000 credits)	Custom
Synthesia	$18/mo (Starter — 14,500 credits/yr)	$64/mo (Creator — 44,000 credits/yr)	Custom
Colossyan	$19/mo (Starter — 15 min/mo)	$70/mo (Business — unlimited NEO 1)	Custom

The pricing reality:

• Synthesia is cheapest to start but uses opaque credit counts. ~120 Starter minutes/year = roughly 10 min/month.
• HeyGen uses credits too (600 = ~10-15 min of standard video). At $29/mo it’s mid-range.
• Colossyan has the clearest per-minute pricing, making it easier to budget for.
