One is a studio for avatar videos. The other's job is to get you users.
Synthesia is the best-known AI avatar studio, and it's excellent at what it's for — training, onboarding, L&D, and explainer video at scale, narrated by an avatar in 140+ languages. But “produce a polished corporate video” and “get my product users” are different jobs. Here's the honest breakdown for a founder deciding between them.
Side by side
| Synthesia | Adluma | |
|---|---|---|
| Built for | training, L&D & explainer video | getting indie founders users |
| URL → finished ad | — you script & assemble in the studio | ✓ paste URL, get the ad |
| Style | polished corporate avatar | scroll-native UGC ad, real-feeling |
| Posts to your channels | — exports an mp4 | ✓ X, TikTok, Reels, Shorts |
| Knows which ad got the signup | — | ✓ per-ad tracked links → signups |
| Finds your winner & remakes it | — | ✓ auto-variants the winner |
| Languages | ✓ 140+ (a real strength) | ✓ 11, native script + captions |
| Pricing model | per-seat subscription, minute-metered | flat · failed renders refunded |
| Entry | limited free plan, then paid tiers | $39/mo · 15 ads · first ad free |
Synthesia genuinely leads on avatar realism, language breadth, and studio control for corporate video. Where it isn't trying to compete is distribution — posting the ad and measuring which one earned a customer.
The honest call
Pick Synthesia if…
- You need training, onboarding, L&D, or explainer video
- You want a studio editor and a large avatar library to build videos yourself
- You need narration in 140+ languages for corporate content
- Distribution and attribution aren't the problem you're solving
Pick Adluma if…
- The problem you're solving is getting users, not making a video
- You want the ad written, cast, rendered, posted, and measured by one agent
- You want to know which ad earned which signup — and auto-double-down on the winner
- You want flat pricing where a failed render refunds itself
Making the video was never the hard part
AI made the avatar video itself nearly free — Synthesia proves how good a scripted talking head can look. What still separates products that grow from products that don't is distribution: getting the ad in front of buyers, learning which angle converts, and doing more of that. Synthesia stops at export — by design; it serves training teams, not growth. Adluma serves one job: your product needs users, so the ad gets posted to your channels, every view carries a tracked link, and when one ad starts earning signups, Adluma spins fresh variants of it automatically. That loop — not the render — is what you're buying.
Adluma vs Synthesia, answered
Is Adluma cheaper than Synthesia?
Adluma starts free — your first ad is written, cast, and shown to you before you ever enter a card. Paid plans are a flat $39 or $99 a month, and a failed or broken render never counts against your monthly ads. You're not paying per attempt to land one video you'll actually run.
Does Adluma just make the ad, or post it too?
Both — and that's the real split with Synthesia. Synthesia is built to help you make the video; Adluma is built around what happens after: it posts the ad across your channels and tracks which specific ad brought a signup. The render is the start, not the finish.
Do I need to know marketing to use Adluma?
No. Adluma reads your site, writes in your own voice, casts a real-feeling creator, and runs the channels for you. It's built for founders who'd rather keep shipping product than learn ads.
Can Adluma make the ad in other languages?
Yes — you can generate your ad in 11 languages including Spanish, Portuguese, French, German, Italian and more, with the creator speaking it natively.
