How to Make Product Demo Videos with Synthesia

Most “AI product demo” posts skip the two facts that actually decide the project. First: a sales demo is not a training module and it is not a YouTube hook. It is a short pitch with a face, a real product on screen, and one next step. Second: the tool this site sends for that talking-head file is Synthesia (synthesia.io). This guide is the working path for a product marketer who does not have a camera crew: script, plan, avatar, screen, CTA, export.

When a product demo needs an avatar — and when it doesn't

Use an avatar when the landing page or the sales email needs a presenter and you cannot or will not book the founder every time the UI ships. Feature launches, pricing-page walkthroughs, outbound sequences, and partner enablement cuts that must stay current are the fit. Edit the script, replace the screen grab, re-render. That is the economic case.

Skip the avatar if the clip is a raw click-path for support, a live webinar, or a founder letter that has to be a real face. Synthesia can record the screen; the avatar is still a narrator. Skip it if you only need a voice over a screen — a stock studio narrator is often cheaper, and that job lives on how to clone your voice only when you actually need a clone. Skip it if the file will run as a public YouTube explainer with ads — start at How to make an AI avatar video instead. Skip it if the file is an internal lesson — the training how-to is the other desk.

The seven-step Synthesia product demo

1. 01

   Write a sales demo script, not a lesson or a hook

   A product demo is a pitch with a face. Open on the buyer problem in one sentence, name the product, walk one workflow on screen, then land a single CTA — trial, calendar, or pricing URL. Spell product names, plan names, and numbers the way a prospect should hear them. If you wanted a learning objective and an LMS package, that is the training how-to. If you wanted a first-second YouTube hook, that is the public avatar how-to.

2. 02

   Confirm avatar-plus-screen is the right demo format

   Use a talking-head avatar when the demo needs a presenter and you cannot book a founder, lights, and a re-shoot every time the UI ships. Skip the avatar for a raw Loom of a live click-path, a webinar, or a narrative brand film. Synthesia can record the screen; the avatar is still a narrator sitting next to the product, not a replacement for the product. A screen-only walkthrough with no face is often enough for an in-app tooltip. A studio day is still the right buy when the CEO has to be the one on camera.

3. 03

   Open Synthesia (synthesia.io) — check the domain

   Synthesia is the presenter desk this page is written for. Synthesys (synthesys.io) is a different company. HeyGen and Pictory show up in the same “AI product demo” search; they are editorial mentions here, not hops. Mixing the names is the expensive mistake. This page sends you to Synthesia only.

4. 04

   Pick the plan that can actually ship a clean demo

   Basic ($0) is an audition: 9 avatars, 10 minutes a month, no clean download. Starter ($29/month, or $18/month billed yearly) is where downloads and logo removal start — that is the usual marketing export. Creator ($89/month, or $64/month yearly) adds personal avatars and API. Enterprise is where brand kits and 1-click translation live. Unused minutes do not roll over. Do not buy Creator hoping the avatar becomes an actor, and do not buy Enterprise for a single English demo.

5. 05

   Build the demo: avatar scenes, product screen, captions

   Write the script into scenes. Open on a head-and-shoulders presenter. Cut to a screen recording of the real product — one workflow, not a feature tour. Come back to the avatar for the close. Add auto-captions so the file works muted on a landing page or in a sales email. Brand kits sit on Enterprise. A stock presenter is enough to prove the cut. Do not commission a founder likeness until this cut has survived a product and legal pass.

6. 06

   End on a CTA card, then generate and QC

   The last beat is a card, not a fade. Put one URL, one offer, and one next step on screen — “Start a trial,” “Book a walkthrough,” or the pricing page — and have the avatar say that same line. Generate, then watch the first second, product names, plan names, and the UI in the screen grab. Mouth-sync is consistently strong in English and major European languages. Hand gestures loop. These are narrators. Edit the script and re-render instead of re-booking a studio.

7. 07

   Export the sales file. Localization is a next step

   Export on the plan that grants a clean download. Confirm commercial and client-facing terms on the plan you will publish from — we do not invent a “full commercial rights” line the pricing page does not print. Ship the primary-language demo first. 1-click translation into 80+ languages is an Enterprise next step after product and legal sign the English (or home-market) cut. Do not localize a script that is still moving.

Avatar plus screen vs Loom vs a studio day

“AI product demo tool” is a search, not a product. The decision is the format. Pricing on the Synthesia column matches the live synthesia.io/pricing page as of August 2026. The yearly toggle shows Starter at $18/month; the FAQ on the same page still quotes $264/year. We report both. Unused minutes do not roll over.

The sales script: problem, product, one workflow, CTA

Write the demo the way you would brief a founder for a two-minute take, then cut it shorter. Most landing-page demos should be 60–90 seconds. A sales-email attach can run to two minutes if the workflow needs the extra beat. Longer than that and you are making a webinar.

Four beats, in this order. One sentence on the buyer problem. Name the product and the job it does. Walk one workflow on the real UI — the path a prospect would click in a trial, not a feature parade. Close on one next step. Spell SKUs, plan names, and numbers the way they should be said. If Legal has not signed the claim, do not put it in the avatar’s mouth.

Do not write a learning objective. Do not write a YouTube hook. Do not ask the avatar to “sound excited.” These presenters are narrators: blink cadence, micro head-tilt, a looping hand. On a head-and-shoulders framing that is enough. Full-body action and emotional range are not the product. Full breakdown of what the avatars actually do is in our Synthesia review.

Avatar plus the product on screen

The picture job is two layers. The avatar opens and closes. The middle is a screen recording of the current product — not a slide that looks like the product, not a generative mock. Record the click-path you want the prospect to take. Crop the chrome you do not want on a public page. If the UI will ship again next week, that is an argument for this format, not against it: swap the grab, edit the line, re-render.

Synthesia’s screen recorder and PowerPoint import exist so the presenter can sit next to existing assets. They do not make the avatar a replacement for the product. A prospect who cannot see the real UI will not convert from a talking head. Captions go on so the file works muted in an email or on a pricing page. Brand kits — locked colors, logos, fonts — sit on Enterprise. For a first demo, a stock presenter and a clean Starter download are the whole buy.

Which Synthesia plan ships the demo in 2026

The 2026 pricing page meters Synthesia in credits plus video minutes. Basic is $0 with 9 avatars and 10 minutes a month — downloads and logo removal start on Starter. Starter is $29/month (1,200 credits, 10 minutes of video or dubbing, 125+ avatars) or $18/month billed yearly. Creator is $89/month (3,600 credits, 30 minutes, five personal avatars, API) or $64/month yearly. Annual Starter lists 14,500 credits and 120 minutes a year; annual Creator lists 44,000 credits and 360 minutes a year. Languages and voices are published as 160+ on every tier. Unused minutes do not roll over.

For a first sales demo, start on Basic with a real script — the claims product already signed, not a placeholder sentence. Go to Starter when you need a logo-off file for the site or a sequence. Buy Creator for a personal founder avatar or the API — not for “more cinema.” Buy Enterprise when brand asks for a kit or you are ready to localize a locked cut. Confirm commercial and client-facing terms on the plan you will export from.

The CTA end card

The last scene is the reason the file exists. Put one offer on a card: a trial URL, a calendar link, or the pricing page. Have the avatar say that same line. Do not stack three next steps. Do not fade to black and hope the landing page below the embed does the work. If the demo lives in an outbound sequence, the card should match the link in the email. If it lives on the homepage, the card should match the primary button.

Watch the export the way a prospect will: on a phone, muted, then with sound. The first second has to name the problem or the product. The last second has to name the next step. Proper nouns and plan names are where avatar reads go wrong — fix the script and generate again. That loop is the product. A studio re-book is what you are not buying.

Localization is a next step, not this brief

Ship the home-market cut first. A second language is a translation of a signed script and a signed screen grab, not a reason to start in Enterprise. Synthesia’s 1-click translation into 80+ languages and brand kits live on that tier. When you are ready, lock the English (or home-market) file, then duplicate. Budget a native-speaker pass outside English and major European languages. Mouth-sync is the reported strength; idioms and product metaphors are where a one-click pass still needs a human.

If the 2026 plan is “one demo, five languages, next quarter,” write that as a follow-on, not as the first invoice. The comparison of presenter platforms — including where Synthesys sits as a different company — lives on Synthesia vs Synthesys and Best AI Avatar Video Tools 2026. This page does not hop there. The only Try button here is Synthesia.

HeyGen, Pictory, and a screen-only recorder — editorial only

Those names sit in the same “AI product demo” search. HeyGen is the usual Synthesia alternative in reviewer write-ups: faster custom-avatar turnaround, punchier social presenters, less of the enterprise kit. Pictory is closer to a text-to-video editor than a governed presenter desk. A Loom or a native screen recorder is the right tool when you do not need a face. None of them have a live hop on this page, so there is no Try button. If you need the talking-head demo we can route, it is Synthesia.
