ngram vs Synthesia
Synthesia generates avatar-led videos from a script and dubs them into 160+ languages. ngram edits the footage you already have, turns docs, URLs, and screen recordings into videos, and lets you approve the script and storyboard before it renders. Here is who each one fits.
ngram
SynthesiaTrusted by teams at
Two tools for two different videos.
Product demos and screen recordings
Record your screen and ngram trims pauses, smooths the cursor, and adds zooms and callouts. Synthesia has no screen capture, so it cannot show the product itself.
Video from docs you already have
Hand ngram a PDF, a URL, a deck, or screenshots and it writes the script and storyboard for your review before it renders. Synthesia starts from a script you write.
Avatar-led training at scale
240+ stock avatars and one-click dubbing into 160+ languages, with SCORM export for any LMS. The right fit for compliance and onboarding courses.

Where each tool wins
Capture a product walkthrough and ngram trims pauses, smooths the cursor, and adds zooms and callouts on the exact UI you show. Synthesia has no screen capture, so it cannot put your product on screen at all.
Drop in a PDF, a product URL, a deck, or screenshots and ngram writes the script and storyboard from the source. Synthesia expects a finished script, and reviewers say its document workflows fall short once teams scale.
ngram shows the script and storyboard first. Fix the structure and pacing in plain language, then render once. You are not regenerating a full avatar take to change one line.
Tell ngram the audience and the channel and it rewrites length, tone, and the closing CTA. A LinkedIn launch clip and a customer onboarding video come from the same source without manual rescripting.
Export 16:9, 9:16, and 1:1 with smart reframing and captions. Synthesia is built around 16:9 presenter videos, so social and vertical formats need rework.
240+ stock avatars, personal avatars from a single photo, and studio avatars with micro-expressions. For videos that are a presenter reading a script, Synthesia's avatar quality and library are ahead of ngram's.
One script publishes across 160+ languages with 1,000+ AI voices and no re-recording. For the same training video in dozens of languages, this is the clearest reason to pick Synthesia.
Native SCORM 1.2 and 2004 packages, dynamic updates, and integrations with Docebo, Moodle, and TalentLMS. ngram has no SCORM export, so L&D teams shipping to an LMS should look at Synthesia.
Synthesia was the first AI video company certified to ISO 42001, on top of SOC 2 Type II, ISO 27001, and GDPR. If your procurement team requires that specific AI management standard, that is a real edge.

Your logo, colors, and fonts on every export, no manual restyling.
