HeyGen vs Synthesia: Quick Verdict

HeyGen is the better choice for marketing video, avatar realism, and multilingual localization; Synthesia is better for structured corporate training with centralized video management. Entry pricing is nearly identical — $29/month each, $24 vs $18 on annual billing — so the decision is workflow, not budget.

All pricing verified against both vendors' pricing pages on August 18, 2026. This comparison is research-based — our hands-on same-script video test of both tools is pending, and this page will gain measured results (render time, artifacts, usable-output rate) when it runs.

Pricing: Same Sticker, Different Meters

HeyGenSynthesia
Free plan3 videos/mo, 1 min each10 min/mo, 9 avatars, 1,200 credits
Entry paidCreator $29/mo ($24 annual), 600 credits/moStarter $29/mo ($18 annual), 120 min/year
Mid tierPro $49/mo, 1,000 credits, 4KCreator $89/mo ($64 annual), 360 min/year
Team tierBusiness $149/mo + $20/seatEnterprise (custom, unlimited minutes)
MeteringCredits per month, rate varies by avatar modelMinutes pooled per year on annual plans

The metering difference is the real story. HeyGen charges 3 credits per minute on standard studio avatars but 20 credits per minute on its newest Avatar IV/V models — a 6x spread inside the same subscription. Synthesia's yearly minute pools (120 on Starter) don't care which stock avatar you use, which makes budgeting simpler but caps total volume harder.

Model it with your own numbers: a team producing 15 minutes of finished video per month on standard avatars fits HeyGen Creator comfortably (~45 credits) and just fits Synthesia Starter's 120-minute yearly pool. The same team insisting on flagship avatar models burns 300 HeyGen credits monthly — still inside Creator, but with little headroom.

When Each Tool Wins

Choose HeyGen if:

  • Your output is marketing, social, or spokesperson video where avatar realism sells.
  • You localize one master video into many languages — nothing else automates lip-synced translation this broadly.
  • You want a photo avatar of yourself producing content at scale from $29/month.

Choose Synthesia if:

  • You maintain a training library that gets updated, re-rendered, and distributed internally — the product is organized around exactly this.
  • Simple per-year minute budgeting beats model-dependent credit math for your finance team.
  • You want the better free plan for ongoing light use (10 minutes every month).

Skip both if you need cinematic text-to-video or B-roll generation — that is Runway/Kling/Sora territory, not avatar presenters. And if your videos are stock-footage montages from scripts rather than talking heads, Pictory does that job from $25/month.

The Bottom Line

At matching prices, buy the workflow: HeyGen for outward-facing video and localization, Synthesia for inward-facing training at organizational scale. Both have real free tiers — run your actual script through each before subscribing; ten minutes of testing answers more than any comparison table.
