Synthesia

What it is

Synthesia (synthesia.io) is a browser AI video platform built around talking avatars for business and training workflows. You pick a stock or personal avatar, paste a script (or feed the AI Video Assistant a document, link, or idea), choose a voice, and generate a lip-synced presenter cut you can localize, brand, and share. Official homepage pitch: #1 AI video platform for business — create, localize, manage, and publish AI videos in one place.

It is not CapCut. CapCut is a timeline you drive shot by shot. Synthesia’s core product is avatar generation plus templates and an assistant, not a general NLE. It is not HeyGen. HeyGen (already listed) leans social-first avatar shorts and translation credit burns; Synthesia’s public positioning centers on Fortune-100 training, LMS/SCORM, compliance (SOC 2, GDPR, ISO 42001, SAML/SSO on higher tiers), and team workflow. It is not ElevenLabs. ElevenLabs is voice-only; Synthesia bundles AI voices (and optional cloning on higher tiers) inside avatar scenes. It is not Fliki or InVideo. Those lean script-to-stock or agent-style Shorts assembly; Synthesia’s search-intent win is a consistent AI presenter face.

Homepage claims checked for this review: 1M+ users, trusted by 60,000+ businesses, 90% of the Fortune 100, 240+ avatars, 160+ languages, rated 4.7 from 2,000+ reviews (G2/Capterra/Trustpilot badges on-page). Feature surface also lists Express-2 avatars (gesture from script), personal/customizable avatars, AI Playground models (page names Veo 3.1, FLUX.2, Nano Banana Pro—treat model lists as moving), AI dubbing with lip-sync, multilingual player, brand kit, collaboration, analytics, and interactive quizzes/CTAs on paid tiers.

Who it’s for

Use it if your faceless bottleneck is “script to on-screen presenter” for explainers, course modules, product updates, or multilingual training clips, and you want one vendor that legal/security can stomach. Official free path fits a smoke test: Free Basic includes 10 minutes/month and 9 avatars with no card; paid Starter unlocks downloads and logo removal so you can actually publish files. Multilingual channels are a fit: pricing and homepage stress 160+ languages and voices, with 1-click translation and deeper dubbing language packs on higher tiers (Enterprise card: 140+ dubbing languages vs 70+ on lower tiers).

Skip Free as a publishing plan. Official Basic card: no download line item on the Starter upgrade list until you pay, watermark/logo removal starts at Starter, and 10 minutes/month is a trial ceiling. Skip Synthesia if you already ship with HeyGen for TikTok/Reels and only need more expressive social avatars — HeyGen is the closer social-first peer. Skip it if you need cinematic B-roll generation (Runway, already listed) or stock-only narration shorts (Fliki / InVideo / Pexels stack). Skip it if you only need voice files (ElevenLabs).

Credit and minute math is the gate. Plans now share a credit pool across AI features; video minutes are consumed when you generate (drafts and preview play do not burn minutes per FAQ), and edits only bill new seconds. Unused minutes do not roll over at period end. Starter’s ~10–12 minutes/month (card vs compare-table mismatch—reconfirm) is enough for a handful of Shorts; Creator’s ~30 minutes/month or 360/year is the realistic solo publishing tier before Enterprise.

Standout details

• Pricing (official synthesia.io/pricing, “New lower prices” banner; monthly/yearly toggle): Basic $0; Starter $29/mo · $18/mo yearly; Creator $89/mo · $64/mo yearly; Enterprise custom. FAQ still quotes Starter $264/year and Creator $804/year — treat the live yearly cards ($18 / $64) as current and re-check before you buy.
• Credits (pricing cards): Basic and monthly Starter 1,200 credits/mo; monthly Creator 3,600/mo; yearly Starter 14,500/y; yearly Creator 44,000/y. Credits are the shared currency for usage-based AI features.
• Video / dubbing caps (pricing cards): Basic up to 10 mins video/mo; monthly Starter card ~12 mins video / 48 mins dubbing (compare table still lists 10 mins video); monthly Creator ~30 mins video / 140 mins dubbing; yearly Starter ~120 mins video / 580 mins dubbing; yearly Creator ~360 mins video / 1,760 mins dubbing; Enterprise unlimited on the card.
• Avatars (pricing compare): Basic 9; Starter 125+; Creator 180+; Enterprise 240+. Personal avatars: Creator lists 5; Enterprise unlimited (fair use); FAQ says one personal avatar on annual Starter/Creator — confirm which seat/plan unlocks your twin before you film reference footage.
• Studio Express-1 avatar add-on: $1,000/year on annual plans; processing up to ~10 days (pricing footnote).
• Languages: 160+ languages and voices on Free through Enterprise cards; AI dubbing output languages 70+ on lower tiers, 140+ on Enterprise. Homepage and marketing also claim 1-click translation; features page marks some 1-click translation depth as Enterprise-only — reconfirm on your plan.
• Export and LMS: MP4 Full HD (1920×1080) downloads from Starter up; SCORM export and SSO called out on Enterprise. Embeds and smart updates keep shared links current after edits.
• Media library: Basic limited Pexels + Soundstripe; paid tiers add Getty Images and Icons8 (pricing compare).
• Compliance marketing (homepage): SOC 2, GDPR, ISO 42001; SAML/SSO on Enterprise. Content moderation applies to generated videos. Avatars are consent-based per Synthesia’s ethics positioning.
• Cancel anytime language appears in the FAQ; unused video minutes do not roll over.

Honest verdict

Try it. Synthesia is the strongest unlisted search-intent pick once HeyGen, Fliki, InVideo, and CapCut are already on the shelf — especially if you want an AI presenter with business-grade localization and compliance rather than another stock-footage Shorts assembler. Start on Free Basic to test avatars and voices, then move to Starter before any real publish (downloads + logo off). Keep Creator for personal avatars, API, interactive video, or higher monthly minutes. Enterprise is for LMS/SCORM, SSO, and unlimited seats/minutes.

Do not buy Synthesia to replace a timeline editor you already finish in, or a cinematic B-roll model you already like. If your only goal is TikTok-native avatar UGC, A/B it against HeyGen before locking annual. Re-check synthesia.io/pricing (credit math, Starter minute line, yearly FAQ vs card) before you subscribe — packaging is mid-shift to credits and the public tables still disagree in places.
