Synthesia transforms video creation by enabling users to produce studio-quality videos with hyper-realistic AI avatars speaking over 140 languages all without cameras or studios. Its intuitive, slide-deck-like interface makes video production accessible and fast, reducing costs and turnaround times dramatically. With over 230 diverse AI avatars, voice cloning, and automatic multilingual translation with perfect lip-sync, it empowers global communication at scale. Synthesia supports collaborative editing, brand customization, live feedback, and secure publishing all built around ethical AI use and explicit consent, making sophisticated video content creation seamless and scalable for businesses worldwide.
Synthesia offers a platform where you input a script, document, webpage or slide deck, select a presenter-avatar and language, then generate a video that delivers your message as if narrated by a real person. The system supports a large collection of avatars of different backgrounds and voices, and offers over 140 languages and accents to choose from. Once the video is generated you can customise background, branding elements such as logo and colours, subtitles, and timings. The tool also supports easy translation and localisation you can switch languages and have the avatar’s lips and voice sync appropriately. Ideal for training materials, marketing content, onboarding videos, multilingual presentations or corporate communication, Synthesia saves the need for filming or hiring actors. Because videos are generated digitally, edits such as updating a script or changing branding are faster than re-shooting. The workflow works online; from script to finished video you are using a browser, which simplifies production especially for teams that produce many videos or need frequent updates

1. Output avatars sometimes appear less expressive or less natural compared to real actors.
2. Videos can feel less emotional or authentic than live-shot material, which can reduce audience engagement.
3. Heavy reliance on provided avatars and templates highly customised or brand-specific stories may still need additional editing.
4. Subscription costs can rise quickly for frequent or large-volume video production.
5. For highly creative or cinematic videos (complex visuals, dynamic camera, mood, acting), the tool’s output may not meet expectations.
6. Some users mention limitations in avatar customisation and fewer options in fine-tuning facial expressions or gestures.
7. Because generation is web-based, heavy editing or long projects may face performance or workflow limits compared to full video editing tools.
