Comparison
Synthesia vs Stand-in: corporate avatars or a creator video?
Synthesia is the avatar tool for training videos and explainers: a presenter avatar reads your script in 140 languages. Stand-in is for social video that has to feel filmed: you film it, and a fictional Stand-in takes your place.
The difference, in hard numbers
| Stand-in | Synthesia | |
|---|---|---|
| What the video is | Your real footage, with a generated fictional Stand-in replacing you whole-person | An avatar presenter reading your script, slides and all |
| Do you film anything? | Yes. Film yourself in your own clothes; a phone camera is fine | No |
| Does the person exist? | No. Every Stand-in is generated and belongs to no one | Stock avatars from real actors, or a custom avatar of you |
| 30-second video | from $3.99 per 30-second video with a $10 credit pack (from $3.63 on Pro) | Starter about $18 to $19/mo for about 10 minutes a month: roughly $0.90 to $1.90 per 30 s if you use every minute |
| Plans | No free video; credit packs from $10 | Free: limited minutes, watermarked. Starter about $18 to $19/mo (10 min/mo). Creator about $64 to $89/mo (30 min/mo) |
| Watermark | Starter plan: yes. Creator, Pro and credit packs without a plan: no | Free: yes. Paid: no |
| Max clip length | Up to 10 minutes on any account; each started 15 seconds uses credits | Minutes per month per plan |
| Voice | Keep your own, or swap it in one tap | Generated voice, 140+ languages, lip sync |
| Look | Plays like a normal phone video, not an avatar | A presenter avatar by design |

The honest pros and cons
What Synthesia does better
- • Script to video in 140+ languages.
- • Slides, templates, brand kits for training content.
- • Cheap per minute if you use the whole allowance.
What Stand-in does better
- • Looks filmed, because it is: your room, your clothes, your movements.
- • Pay per video; no monthly minutes to use up.
- • Anonymity: a fictional person, not a custom avatar of you.
Questions
- Is Synthesia good for TikTok or Instagram?
- Synthesia is made for presenter videos: explainers, training, announcements. Social feeds reward phone-shot video with a real person. Stand-in keeps the phone-shot footage and only replaces you.
- How much is Synthesia compared to Stand-in?
- Synthesia Starter is about $18 to $19 a month for about 10 minutes of video; Creator is about $64 to $89 for 30 minutes. Stand-in is from $3.99 per 30-second video with a $10 credit pack (from $3.63 on Pro).
- Does Synthesia make a copy of me?
- Synthesia offers custom avatars built from your own recording. Stand-in never builds a twin of you: every Stand-in is a generated fictional person.
- Can Stand-in translate my video?
- Not today. Stand-in keeps the words you recorded; you can swap the voice, not the language.
