Create AI-driven video content with realistic avatars
Synthesia is an AI video creation platform that turns scripts and slides into presenter-led videos using photoreal avatars and multilingual synthetic voices. It’s ideal for L&D, enablement, and marketing teams needing repeatable, on‑brand content without cameras or studios. Pricing is seat-based with a low-cost Starter plan, higher‑usage Creator seats, and enterprise contracts for custom avatars, SSO, and SLAs.
Synthesia is a Video AI platform that converts text scripts into finished videos using AI avatars and synthetic voices. It automates presenter-led video production, offering 70+ prebuilt avatars, custom brand templates, multilingual speech in over 120 languages/accents, and PowerPoint-to-video imports. The key differentiator is its avatar studio and enterprise-friendly compliance features that eliminate the need for cameras or hiring presenters. It serves L&D teams, marketing managers, and product teams who need repeatable, scalable video content. Pricing is tiered — a paid Pro seat is required for exports and enterprise plans unlock custom avatars and higher usage.
Synthesia launched as a UK-based AI video startup focused on replacing camera shoots with text-to-video workflows, positioning itself as a platform for creating presenter-led video content without cameras, microphones, or studios. Its core value proposition is delivering consistent, brand-safe videos at scale by combining synthetic avatars, lip-synced speech, and a web-based editor. Founded to streamline internal comms and learning content production, Synthesia emphasizes compliance controls, enterprise admin features, and language reach to reduce time and cost compared with traditional video production.
The product surface centers on four main features. The Avatar Library provides 70+ prebuilt human-looking AI presenters you can select per video; Enterprise customers can request custom, verified avatars based on recorded actors. The Studio editor converts text or uploaded slides into scenes, supporting script editing, scene timing, background images, and on-screen text overlays. Voice and language support covers over 120 languages and accents with lip-sync, and you can upload custom voice models via Studio for Enterprise. Exports include MP4 and SRT captions; file resolution settings and branding controls (logo, font, color palette) are editable across projects. The platform also supports CSV batch generation for scaling dozens of personalized videos using input variables.
Pricing follows a seat-and-feature model. There is a free demo that lets you create one short sample video with watermark via the website, but regular exports require the paid Pro plan which is listed at $30/month per creator seat billed annually for the individual Pro plan (pricing and billing cadence available on Synthesia's site). The Team and Enterprise tiers are custom-priced; Team adds multi-seat management, shared templates, and more monthly video minutes, while Enterprise unlocks custom avatars, SSO, advanced security controls, and higher generation quotas. Additional costs can apply for custom avatar creation and large-volume batch generation; quotes are provided during sales conversations for enterprise-level usage.
Teams using Synthesia typically include Learning & Development managers who produce training modules (reducing video production time from days to hours), Marketing managers creating product explainers and localized campaign videos, and HR/Comms leads producing company updates or onboarding content. Concrete examples: an L&D Manager using Synthesia to convert 100 slide-based training modules into narrated videos within a month, and a Product Marketing Manager creating 20 localized promo videos for five markets. Compared with competitors like Descript, Synthesia prioritizes avatar-led presenter videos and enterprise security rather than multi-track audio editing or screen recording features.
Three capabilities that set Synthesia apart from its nearest competitors.
Which tier and workflow actually fits depends on how you work. Here's the specific recommendation by role.
Buy for quick presenter-led explainers without filming; skip if you need cinematic control or 4K.
Buy to standardize branded tutorials and cut turnaround; skip if most work is live-action shoots.
Buy for scalable L&D and compliance training with governance; skip if on-prem/self-host is mandatory.

Copy these into Synthesia as-is. Each targets a different high-value workflow.
Role: You are a Synthesia video producer converting slides into a single presenter-led video. Constraints: output a 5-minute script for a single avatar, 8–10 scenes mapped to slides, each scene 25–40 seconds; choose an avatar name from Synthesia’s library (e.g., 'Ava'), standard neutral English voice, include on-screen headline and one supporting bullet per scene, generate closed captions (SRT). Output format: JSON array 'scenes' with fields: slide_number, start_time, end_time, avatar, voice, speaker_script, on_screen_text, srt_captions. Example scene: {"slide_number":1,"start_time":"00:00:00","end_time":"00:00:30","avatar":"Ava","voice":"en-US-neutral","speaker_script":"Welcome...","on_screen_text":"Course overview","srt_captions":"1\n00:00:00,000 --> 00:00:30,000\nWelcome..."}.
Role: You are writing a 90–120 second CEO update script for Synthesia. Constraints: single avatar (professional, authoritative), tone: concise and optimistic, include exactly three business updates (one metric, one initiative, one team shoutout), one 15-second closing CTA, and provide SRT captions and suggested on-screen headline and lower-third text. Output format: provide a single JSON object with fields: duration_seconds, avatar, voice, full_script, timestamps (start/end for each update), on_screen_elements (headline, lower_third), srt_captions. Example: {"duration_seconds":105,"avatar":"Ethan","voice":"en-GB-formal","full_script":"..."}.
Role: You are a product marketing writer preparing five localized 30-second promo scripts for Synthesia. Constraints: produce one script per locale (US English, UK English, Mexican Spanish, German, French), keep 30±3 seconds each, use the same avatar appearance but choose voice/accent per locale, include localized opening hook, three key product benefits (one sentence each), localized tagline translation, and CTA. Output format: JSON array of 5 objects: {locale, avatar, voice, duration_seconds, script, on_screen_text, translated_tagline}. Example item: {"locale":"es-MX","avatar":"Maya","voice":"es-MX-female","script":"...","translated_tagline":"Tu herramienta, tu ventaja"}.
Role: You are an L&D producer converting 20 slides into four microlearning videos for Synthesia. Constraints: create 4 videos (~3 minutes each), map slide ranges to each video, include scene-level speaker script, one 1-question knowledge check at the end of each video (MCQ with 4 options and correct answer), include captions and suggested thumbnail text, use brand voice (concise, supportive). Output format: JSON with videos array where each video has: video_id, slide_start, slide_end, duration_seconds, scenes[], quiz{question,options,correct_index}, thumbnail_text. Example quiz: {"question":"What's the primary benefit?","options":["A","B","C","D"],"correct_index":2}.
Role: You are a compliance learning designer and Synthesia producer building a 5-part training series. Instructions: produce five 6–8 minute modules covering Policy, Risk, Reporting, Case Studies, and Certification; for each module provide a scene-by-scene script with timestamps, avatar selection (senior neutral presenter), two scenario-based interactive decision points per module with branching text (if trainee selects A -> redirect to remediation scene ID X; if B -> continue), three assessment questions per module with scoring rubric, required captions, and suggested graphics (charts/icons). Output format: JSON {modules: [{id,title,duration,scenes[],branches[],assessments[],srt_captions}]}. Few-shot example: module snippet: {"id":2,"title":"Risk","scenes":[{"scene_id":"2.1","start":"00:00","end":"00:45","script":"..."}],"branches":[{"decision_id":"D1","prompt":"...","options":[{"opt":"A","goto":"remed_2A"},...] }],...}.
Role: You are an enterprise video strategist creating a 7-video onboarding program for Synthesia with compliance and governance steps. Requirements: deliver seven 2–4 minute scripts (welcome, values, IT security, HR policies, product overview, first-90-days, wrap-up), specify custom-avatar usage instructions (consent, legal approval text), localization needs (EN/ES/FR), metadata tags for DAM (title, keywords, retention_policy), access control checklist (who can export/edit), and a production checklist (reviewers, caption QA, final sign-off). Output format: JSON {program:{videos:[],avatar_instructions,localization,metadata_template,access_control,production_checklist}}; include a short example video object.
