Both tools make business video easier, but they solve completely different problems. Loom captures you talking — your face, your voice, your screen — and ships it in 90 seconds. Synthesia generates a polished AI avatar reading a script you typed, in any of 140+ languages, without you ever sitting in front of a camera.
Picking the wrong one wastes a budget line and frustrates your team. This comparison breaks down where each tool actually wins.
Why This Comparison Matters
Async video has eaten the "could've been an email" meeting. But "video" now splits into two distinct workflows:
- Personal async video — a quick walkthrough, bug report, customer reply, or status update. The value is presence: your tone, your cursor, your face.
- Produced corporate video — training modules, product explainers, localized onboarding, sales enablement. The value is polish and scale: consistent quality, multiple languages, no reshoots.
Loom owns the first workflow. Synthesia owns the second. They overlap less than the category page suggests.
Feature Comparison
| Feature | Loom | Synthesia |
|---|---|---|
| Primary input | Screen + webcam recording | Text script → AI avatar |
| Avatars | You (real webcam) | 200+ stock avatars, custom avatars on higher plans |
| Languages | Recording in any language you speak | 140+ languages, AI-dubbed |
| Editing | Trim, AI transcript cleanup, fillers removal | Full multi-scene editor, brand kit, templates |
| Time to first video | ~60 seconds | ~10 minutes (write, generate, review) |
| Reshoots required for edits | Yes (re-record) | No (change the text, regenerate) |
| Max video length | Unlimited on paid | Capped by minutes/month allowance |
| Output quality | 720p–1080p webcam | 1080p studio-grade avatar render |
| Collaboration | Comments, reactions, threads on video timeline | Shared workspace, review-and-approve flows |
| Compliance | SOC 2, GDPR | SOC 2, GDPR, enterprise SSO/SAML |
| API | Limited | Full programmatic video generation API |
Pricing Comparison
Loom
- Free — $0/mo, 5 videos per person, 3-minute cap. Fine for trying it; useless for actual work.
- Business — $8/user/mo, unlimited videos and length, custom CTAs, view analytics.
- Enterprise — Custom pricing, SSO, advanced admin, custom retention.
Synthesia
- Free — $0/mo, 3 minutes/month total, watermarked, 9 avatars.
- Starter — $22/mo, 10 minutes/month, 70+ avatars, no watermark.
- Creator — $67/mo, 30 minutes/month, 90+ avatars, brand kit, multi-scene.
- Enterprise — Custom, unlimited minutes, custom avatars, API, dedicated account manager.
The pricing model is fundamentally different. Loom prices per seat — a 20-person team on Business is $160/month for unlimited video. Synthesia prices per output minute — a 20-person team needing 100 minutes/month of polished avatar video is paying for an Enterprise plan, easily 10× the Loom number.
If you're calculating cost-per-video, Loom is dramatically cheaper for high-volume informal communication. Synthesia is dramatically cheaper than hiring a video crew for the same polished output.
Use Case Scenarios: When to Pick Each
Pick Loom when:
- Bug reports and engineering walkthroughs. "Here's what's broken, here's the console, here's the reproduction." Screen + voice in 90 seconds.
- Async standups and weekly updates. Your team is distributed across time zones and you want presence without meetings.
- Customer support replies. A 2-minute screen recording resolves what 6 email exchanges couldn't.
- Sales follow-ups and demos. A personalized walkthrough sent to a specific prospect after a call.
- Internal knowledge transfer. "Here's how this part of the codebase works" — captured once, watched whenever someone joins.
Pick Synthesia when:
- Employee onboarding and training at scale. 50 modules that need to look consistent, get updated quarterly, and ship in 8 languages.
- Localized product education. Same explainer, 12 languages, identical pacing — without hiring 12 voice actors.
- Compliance and policy videos. The text needs to be exactly right, will be edited every six months, and someone in legal will rewrite a line at the last minute. Loom would mean a full reshoot. Synthesia means changing one word in the script.
- Marketing explainers where you don't want to be on camera. Founder-led video isn't always the brand. Sometimes you need a polished presenter without burning founder time.
- Customer-facing product tutorials at scale. Hundreds of feature videos that look like they came from a real studio.
Edge case: Synthesia for internal updates?
Some teams use Synthesia for weekly company updates by typing the script. It's faster than producing a Loom in the sense that you don't need to look presentable — but it loses the personal connection that's exactly why async video works in the first place. Most teams that try this revert to Loom within a quarter.
Verdict
They're not really competitors — they're complementary tools, and most serious operations should use both.
For day-to-day team communication, bug reports, customer support, async standups, and any video where you being present is the point: Loom wins decisively. The $8/seat pricing, 60-second time-to-video, and unlimited length make it a no-brainer.
For training content, localized onboarding, compliance videos, and any production where polish and editability matter more than presence: Synthesia wins decisively. The ability to ship the same video in 140 languages without ever booking a studio is genuinely category-defining, and the editability advantage (change a word, regenerate) saves more than it costs the first time legal asks for a revision.
Don't pick one to do both jobs. A team forcing Loom to produce polished training video ends up with inconsistent quality and re-recording fatigue. A team forcing Synthesia to handle async updates ends up with sterile, low-trust communication that no one watches twice.
If you have to pick one for a small team that does mostly internal communication: start with Loom. If you're standing up a training, enablement, or L&D function with budget: start with Synthesia. Most companies past 50 people end up running both.
