Synthesia Review 2026: Plans, Credits, Plan Gates and Limits

The verdict: a training-video factory with hard plan gates

Synthesia is worth buying if your job is presenter-led video at volume: training modules, onboarding, policy updates and sales explainers that get rewritten and re-voiced often. You write or import a script, an AI avatar presents it in a scene-based editor, and voices cover 140+ languages and accents on every plan. Real use starts at Starter, at $19 a month billed monthly or $14 a month billed yearly ($168 a year), because the free Basic plan watermarks videos and cannot download them as MP4 files.^[1] The catch is structure, not quality. SCORM, translation and shared editing sit on Enterprise only.

The buyers who get the most from it are learning and development teams, HR, sales enablement and internal communications groups that publish similar videos every week and update them by editing text instead of reshooting. Three other buyers should think twice. If you need short cinematic clips rather than a presenter reading a script, the generative tools in our AI video generators category (Runway, Kling AI, Higgsfield, Google Flow) are built for that, although Synthesia itself offers Veo 3.1 and Gemini Omni (beta) clips inside AI Playground. Marketers planning paid social ads with stock avatars hit a licensing wall. Teams with several editors below Enterprise hit a seat wall.

Synthesia is made by Synthesia Limited, a London-based company founded in 2017, led by co-founder and CEO Victor Riparbelli. It describes itself as a product for businesses and organizations, not consumers, and the whole plan structure follows from that: the free tier is a demo, the paid self-serve tiers are built around a single creator, and anything that looks like a department rollout is pushed toward a sales conversation.

What you pay, and what credits actually buy

Synthesia sells four plans and, since October 2026, meters usage in credits instead of minutes. Every plan, Basic included, gets a monthly free allowance of 10 minutes of video or dubbing, 3 survey responses and 500 credits; paid plans add their own credits on top, and the included minutes are used first. Pro is sold at five credit levels on the same plan. Starter and Pro are priced per account with one editor, so a second person who needs to edit pushes you to Enterprise rather than to a second seat.

Avatar video costs about 100 credits per finished minute, charged only on newly generated avatar footage and never on previews or edits you have not rendered. The pricing page translates that into the 10 included minutes plus up to about 12 more a month on Starter, and up to about 60 more on Pro. Dubbing takes 40 credits a minute, or 80 with lip-sync. Survey responses beyond the free three cost 350 credits each. Syren, the AI video agent (October 2026, labeled beta), typically uses 1,000 to 2,000 credits per finished minute, according to the pricing page, so agent-built video burns credits far faster than editor-built video.

Yearly billing pays off quickly. By our arithmetic, Starter billed yearly saves $60 a year and Pro billed yearly saves $360 a year against the monthly list price, so at list price yearly wins if you would stay 9 months or more on Starter and 8 months or more on Pro. The monthly Starter card shows a first-month offer of $9, then $19 a month. The monthly Pro card shows a first-month offer of $49, then $89 a month. For a new buyer who would take that offer, yearly pays off only from 10 months on Starter and 9 months on Pro. Enterprise lists unlimited video minutes, but Syren, dubbing and other credit products still draw on contracted credits there.

Credits and the free allowance reset every billing period with no rollover, and yearly plans receive the whole year's credits upfront. When credits run out, video creation pauses until renewal unless you buy more or move up a plan, and upgrading mid-cycle forfeits the unused balance. Deleting a video does not return its credits either. Our Synthesia pricing guide walks through every Pro credit level.

The gates that decide which plan you need

Price matters less here than where each feature lands. MP4 download starts at Starter; interactive CTA buttons, branching and bulk personalization from spreadsheets start at Pro, and the Video API is limited to Pro (up to 360 minutes a year, deducted from plan limits) and Enterprise. Quizzes, SCORM export, 1-Click Translation, brand kits, the multilingual player, workspaces, live collaboration and SSO are Enterprise only. For most training teams, the SCORM gate is the real price. Without it, courses reach your LMS as embeds from the Synthesia player.

That player matters in two other ways. Videos with interactive elements cannot be downloaded as MP4 at all, and video analytics only count plays inside the Synthesia player, not MP4 files uploaded elsewhere. Collaboration is thin below Enterprise: Starter adds 3 guests and Pro 5 guests, and guests can only view and comment. Self-serve accounts cannot add more editors, which is the point most growing teams miss when they compare monthly prices.

Avatars follow the same ladder. Stock avatars grow from 9 on Basic to 125+ on Starter, 180+ on Pro and 240+ on Enterprise. Personal avatars, your own digital twin from one photo or a short video, start at Starter with 3, rise to 5 on Pro and carry no fixed cap on Enterprise, subject to reasonable consumption and compute. A Studio avatar filmed on green screen is a $1,000-a-year add-on for annual plans only and can take up to 10 days to process. Voice cloning is on every plan, Basic included, in 32 languages outside Enterprise.

What changed in 2026

In 2026 Synthesia added an AI layer on top of its scene editor. The chat-based Assistant arrived in July 2026 on Starter and above, turning a prompt, a URL or a file into an editable outline and then a draft video; the Express-3 avatars launched the same month on a staged rollout. In October 2026 credits replaced minutes, and Syren followed, an agent labeled beta that assembles a whole video from your decks, documents and links. Syren runs on all plans, up to 60 minutes on paid plans and 3 minutes on Basic, and its videos cannot be opened in the scene editor.

October 2026 also brought Sessions. Roleplay Sessions let a learner practice a spoken conversation with an avatar that pushes back, then get scored against a skill rubric; free plays come with 10 a month on Basic, Starter and Pro and 25 a month per organization on Enterprise, and seated learners cost $29 per learner seat a month billed monthly or $25 billed annually, a separate subscription. Survey Sessions run spoken interviews of up to 10 questions, and responses are not anonymous. Interactive Avatars have been available on all plans since October 2026, labeled beta. In November 2026 Synthesia opened an MCP connection for ChatGPT and Claude in public beta: connecting works on every plan, but creating a Studio draft needs a paid plan.

Moderation, consent and your data

Every video passes automated moderation plus human review at generation. Stock avatars are limited to neutral, factual content, so scripts touching medical, legal, financial, news or political topics, or naming real people and companies, can be refused for a stock avatar and may need a personal or Studio avatar. Appeals are open only to paid plans, one per decision, reviewed within 48 hours, and the decision is final.^[2] Basic users cannot appeal. Earlier approval of similar content guarantees nothing.

Advertising is the second limit. Stock avatars may not appear in paid advertising, including paid social, paid TV and programmatic, without Synthesia's written consent, and they cannot endorse products or act as spokespeople. Organic posts, training and product pages are fine. Synthesia creates a personal avatar or voice clone only with a live consent recording from that same person, who must be of legal age; it refuses celebrities, public figures, deceased people and anyone who has not consented, and you cannot create a photo avatar of someone else even with their permission.

On data, Synthesia says it does not use customer data to pre-train its AI models, and its terms say you own the videos you create. Synthesia says it holds SOC 2 Type II, ISO/IEC 27001, 27701 and 42001, and stores customer data in the EU. It is not a HIPAA business associate, so keep protected health information out. Content credentials are added to videos on every plan. Money rules are strict. All purchases are non-refundable, even if the subscription went unused, unless a contract says otherwise. Plans renew automatically, and the Customer Terms ask for 30 days' notice of non-renewal, so cancel well before renewal. After canceling, your videos become inaccessible at the end of the billing period. Download them first.

How we score Synthesia

Synthesia lands at 4.0/5. We weight Capability & depth, AI and Value for money most heavily, then Ease of use and Support & reliability, with Integrations, User sentiment and Docs & learning resources counting less. Capability and AI score high, while the plan gates and the single-editor model pull Value for money down. The strengths are hard to match for a training team: script-driven updates, consent rules that protect the people behind avatars, EU data storage on every plan and a fast 2026 release pace. The weaknesses are commercial rather than technical, and they show up the moment a second editor or an LMS package enters the picture.

The ratings above show where each review platform lands. Reviewers on Trustpilot most often complain about rejected videos, support and avatar quality, with credits close behind; treat that as a map of where friction happens, not as a trend. If you are weighing it against the closest avatar platform, our HeyGen vs Synthesia comparison sets the two side by side, and our Synthesia alternatives cover the wider field.

The bottom line

Synthesia earns its place for teams that turn scripts into presenter videos every week and need them in many languages, with consent and data rules a compliance team can sign off. Buy Starter for a single creator who needs downloads or watermark-free LMS embeds, Pro when you need more volume (6,000 vs 1,250 credits a month) or when branching, personalization or the API matter, and talk to sales as soon as SCORM, translation or a second editor is on the list. Skip it for cinematic clips or paid ads with stock avatars. Our score reflects a strong product sold with gates you must plan around before paying.
