HeyGen vs Synthesia: Welche KI-Videoplattform passt zu deiner Aufgabe?
HeyGen und Synthesia machen beide aus einem Skript ein Video mit einem KI-Sprecher. Diese Seite vergleicht die beiden anhand ihrer eigenen veröffentlichten Angaben und zeigt dann, wo RYLA hineinpasst, ein Tool um einen gestalteten Charakter statt um einen Sprecher.
Welches solltest du nutzen?
you want to design one new AI character step by step, lock its face in a reference sheet, and make photos, image-to-video, talking clips and video swaps of that same character in one workspace, rather than a presenter reading a script
you want presenter-style videos from a script: HeyGen for an avatar of yourself, voice cloning and translation into many languages on a free plan, Synthesia for business videos with stock or personal avatars, team guests and a free Basic plan
Wo jede Plattform gewinnt
HeyGen (heygen.com) and Synthesia (synthesia.io) are both AI video platforms where an avatar presents a script, and both offer stock avatars, an avatar of yourself, voice and translation or dubbing. HeyGen leans toward creators and marketers, with a free plan, a Video Agent and video translation with lip sync. Synthesia leans toward business training and communication, with a free Basic plan, a shared pool of monthly credits and team guests on paid plans. In the table, each HeyGen or Synthesia cell lists both products so you can read the head-to-head directly; the RYLA column shows a third option. Facts come from the public HeyGen pricing page and the Synthesia pricing page, read on 9 November 2026. RYLA plans come from the RYLA pricing page. The table includes the rows where HeyGen or Synthesia is ahead.
| Feature | RYLAEmpfohlen | HeyGen or Synthesia |
|---|---|---|
| Primary job |  Design one recurring AI character and generate its photos, video, and talking clips. | HeyGen: talking videos of you or a stock avatar, video translation and a prompt-based Video Agent. Synthesia: presenter-style business videos with stock or personal avatars and dubbing. |
| Free plan | Paid plans; current plans and credits are on the pricing page. | HeyGen: Free, 3 videos a month up to 1 minute each. Synthesia: Basic, $0 with 500 credits a month (about 10 minutes of video) and the Synthesia logo on videos. |
| Entry paid plan | Basic: $34.99 a month, 10,000 credits a month. | HeyGen: Creator at $29 a month. Synthesia: Starter at $19 a month ($9 for the first month), 1,250 credits a month. |
| Higher plans | Agency: $199.99 a month, up to 15 influencers. | HeyGen: Pro from $49 a month, Business at $149 a month plus $20 per extra seat a month. Synthesia: Pro at $89 a month (6,000 credits). Both list a custom Enterprise plan. |
| Avatar of yourself |  The builder designs a new character; making an avatar of yourself from a recording is not part of it. | HeyGen: custom avatars on every plan (1 on Free, 5+ on Business), plus voice cloning. Synthesia: personal avatars from Starter (3 on Starter, 5 on Pro), none on Basic. |
| Stock avatars | Not a stock presenter library; every character is one you design. | HeyGen: 500+ ready-made presenters listed on the Free plan. Synthesia: 9 AI avatars on Basic, 125+ on Starter, 180+ on Pro. |
| Languages | Talking clips use the voice chosen in the builder; no translation feature. | HeyGen: translation in 30+ languages on Free and 175+ languages and dialects on paid plans. Synthesia: 140+ languages and voices, dubbing output in 70+ languages on Basic, Starter and Pro. |
| Teams | Not compared here; current plan features are on the pricing page. | HeyGen: seats on Business at $20 per extra seat a month. Synthesia: 1 editor with 3 guests on Starter and 5 guests on Pro. |
| One designed character across photos and video | After the builder you pick a base image, and RYLA generates a reference sheet of that face; Studio photos, image-to-video, and talking clips are made from it. | Both are video-first presenter tools; photo generation of one recurring designed character is not described on their pricing pages. |

Dasselbe Gesicht in vier verschiedenen Szenen
Jedes Bild hier wurde mit RYLA erzeugt. Eine Person, vier verschiedene Szenen, nichts dazwischen retuschiert.
Wo RYLA gewinnt
HeyGen in einer Zeile
Eine KI-Videoplattform für Videos von dir oder einem Standard-Avatar, mit Stimmklonen, Übersetzung in 175+ Sprachen in bezahlten Plänen, Video Agent und Free-Plan, von 29 $ bis 149 $ pro Monat vor Plätzen.
Synthesia in einer Zeile
Eine KI-Videoplattform für Unternehmensvideo, mit 125+ bis 180+ Standard-Avataren in bezahlten Plänen, persönlichen Avataren, Synchronisation, Gast-Plätzen und kostenlosem Basic-Plan, von 19 $ bis 89 $ pro Monat.
Wo RYLA anders ist
RYLA startet beim Charakter, nicht beim Skript. Du gestaltest ein Gesicht im Builder, RYLA erzeugt ein Referenzblatt davon, und jedes Foto, jeder Clip und jedes Sprechvideo danach stammt von diesem einen Charakter.
Ehrlich bei der Lücke
Bei Sprecher-Videos, Übersetzung, einem Avatar von dir, Team-Funktionen und einem Free-Plan liegen HeyGen und Synthesia vorne. RYLA bietet das nicht und startet teurer als beide Einstiegspläne.
Wo HeyGen or Synthesia noch gewinnt
For presenter-style video, HeyGen and Synthesia are ahead of RYLA, and between the two the choice depends on the job. HeyGen is the more creator-oriented one: a free plan, a custom avatar on every plan, voice cloning and translation into 175+ languages on paid plans. Synthesia is the more business-oriented one: a lower entry price ($19 against $29 a month), dubbing and guest seats for reviewers. RYLA does not offer an avatar of you, voice cloning, translation, a stock presenter library or a free plan. If you need a training video, a sales message or a localized explainer, one of those two is built for it and RYLA is not.
Wechsel von HeyGen or Synthesia zu RYLA
Nothing imports from HeyGen or Synthesia into RYLA, so adding a recurring character means building it once. This is the actual sequence in the RYLA builder:
- Pick a niche, then gender and style.
- Set the look: ethnicity, age, skin, eyes, face shape, and hair.
- Choose outfit and scene, then personality and a name, then a voice.
- Generate base images and pick the one that becomes your character.
- RYLA generates a reference sheet of that face.
- Finalize, then create new photos in Studio, motion with image-to-video, talking clips in Avatar Video, and swaps in Video Swap.
Here is one RYLA character from the showcase on this site, generated in two different scenes:
Current plans are on the pricing page. For one-on-one comparisons, see the HeyGen alternative and Synthesia alternative pages, or the talking avatar page.
Fazit
Choose HeyGen if you want a talking video of yourself or a stock avatar, voice cloning, translation into many languages and a free plan. Choose Synthesia if you want business videos with stock or personal avatars, dubbing, guest seats for reviewers and a free Basic plan at a lower entry price. Choose RYLA if you would rather design one character in a guided builder, lock its face in a reference sheet, and make its photos, clips, talking videos and swaps in one place.
