Humanizing vs. Synthesia: interactivity explained
Synthesia and Humanizing both work with digital avatars, but they solve different tasks. Synthesia is an AI video platform: you use it to produce professional videos with AI avatars — and with the 'Interactivity' feature, these videos are extended with call-to-action buttons, quizzes and branching. Humanizing, by contrast, does not deliver pre-produced videos, but live conversational real-time avatars that speak freely, listen and resolve cases end-to-end at the physical or digital point of contact.
The decisive difference lies in the medium: Synthesia interactivity is a playback video in which the viewer chooses between predefined paths. A Humanizing avatar conducts a genuine, open conversation in real time — it responds to what the person in front of it actually says, and completes the case instead of merely forwarding it. This article places both approaches fairly and shows when each one fits.
What is Synthesia interactivity?
Synthesia is an AI video platform that lets you create professional videos without a camera, studio or actors — based on AI avatars and AI voices. The 'Interactivity' feature turns such a video into a clickable experience: viewers can use embedded elements to control what happens next.
Typical interactive building blocks are call-to-action buttons that point to forms or documents, quizzes to check knowledge, branched scenarios with selectable paths, as well as integrated analytics of completion and quiz rates. The result, however, remains a pre-produced video whose branches were defined in advance.
- AI video creation without a camera or studio
- More than 240 AI avatars and over 1,000 AI voices
- Interactivity: CTA buttons, quizzes, branching, analytics
- Strong for training, onboarding and marketing videos
What sets a live avatar apart?
A Humanizing avatar is not a video, but a dialogue-capable real-time system: it listens, answers freely and leads the conversation like a human counterpart — without predefined click paths. Instead of choosing from fixed options, the person in front of it simply says what they need, and the avatar responds to it.
The second difference is agentic: the avatar does not merely forward or show a button, but resolves cases end-to-end at the point of contact. To do so it runs hardware-flexibly on a stele, kiosk, tablet, web or smartphone, speaks over 100 languages, is accessible in line with the BFSG, and is hosted in a GDPR-compliant manner in the EU or in Germany.
- Free real-time dialogue instead of a playback video with click paths
- Agentic and end-to-end instead of merely forwarding
- Over 100 languages, accessible in line with the BFSG
- Hardware-flexible: stele, kiosk, tablet, web, smartphone
- GDPR-compliant, hosting in the EU/Germany
Which use cases need real-time dialogue?
Wherever a person has a specific request and immediately expects an answer or a completed case, a pre-produced video is not enough. That calls for an avatar that listens, asks follow-up questions and acts — at reception, in the branch, at the factory gate or in self-service on the website.
Humanizing is in production at exactly such points of contact: more than 25 savings banks use Humanizing avatars in the branch. Added to this are wayfinding in large buildings, truck check-in at the factory gate and product advice in retail. For a quick, independent start there is the self-service variant Cosmo from EUR 40/month; larger initiatives are delivered by Humanizing as a guided project engagement.
- Reception & branch: clarify requests and complete them directly
- Wayfinding in large buildings in the chosen language
- Truck check-in at the factory gate without waiting time
- Self-service on the website that really gets things done
What ROI arises at the point of contact?
Synthesia reports measurable effects for interactive videos — for instance higher completion rates in training and better conversion in demos. That is a strong lever for content that is produced once and played back many times.
A live avatar raises ROI at a different point: at the real point of contact. Because it resolves requests end-to-end, it relieves staff at reception, on the phone and in service, keeps waiting times short, and serves multiple languages without additional translation effort. Instead of a playback explainer video, there is a conversation partner who actually sees the case through — around the clock and identically at every location.
Synthesia or Humanizing — what fits when?
Both platforms are strong in their field; the choice depends on the task. If the goal is to produce scalable training, onboarding or marketing videos with interactive elements, Synthesia is the obvious solution. If the goal is to advise live at the physical or digital point of contact and complete cases, a Humanizing real-time avatar is the right tool.
The two approaches are not mutually exclusive: an interactive video explains something once to many, a live avatar handles every request individually in the moment. Anyone covering both levels combines reach with genuine case processing.
- Synthesia: AI videos for training, onboarding, marketing — produced once, played back many times
- Humanizing: live dialogue at the point of contact — individual and end-to-end
- Synthesia is asynchronous (video), Humanizing is synchronous (real-time conversation)
- Both combinable: reach plus genuine case processing
