By Eli Mercer – AI strategist & founder of NextGenAIFinder
You know what I wish I had when I was building out a remote onboarding program for my growing team?
A tool like Synthesia.
If you’re in HR, Learning & Development, or you’re just stuck making training videos on a regular basis—this is the blog post to read.
In 2025, creating effective and scalable employee training content isn’t optional anymore. It’s mission-critical. Whether you’re onboarding 5 remote hires or global teams across time zones, AI video tools have officially entered the chat. The real question now is…
Should you trust Synthesia to power your internal training and onboarding videos this year?
I rolled up my sleeves, tested the platform, dug through real reviews, and compared it against its competitors like Pictory and DeepBrain. Let me break it down for you—Eli-style: no fluff, no hype, just high-ROI info you can act on.

Synthesia is an AI-powered video generation platform that lets you create professional-grade videos using nothing but text. That means:

Why Is AI Video Perfect for Training and Onboarding?
Training content needs to be clear, consistent, and—let’s be real—digestible.
Here’s why AI-generated video content is crushing it in L&D circles right now:
- 🧩 Maintain Visual Consistency: Instead of different trainers with different styles, AI avatars ensure uniform messaging across every session.
- ⏱️ Update Video Trainings Fast: Policies change. Software evolves. AI lets you edit and re-export new training modules within minutes.
- 🌎 Go Global Instantly: Need onboarding in Spanish, German, or Mandarin? Synthesia translates and syncs voiceovers without needing an extra voice actor.
If you’re onboarding new hires across departments or new markets, the value here is massive.
Traditional Video vs. Synthesia
Let’s talk brass tacks.
Hiring a video crew, scripting content, booking talent, editing for weeks—it’s slow and expensive. Synthesia flips this entire process.
How Synthesia wins:
- 💸 Costs less – No editors, no actors, and no gear.
- ⚡ Faster delivery – Build a training module in the morning. Use it in the afternoon.
- 🧑💼 Custom Avatars – Create AI versions of your internal trainers to keep that human touch.
Wondering if it’s worth the jump from traditional production?
You decide: Would you rather spend $3,000 and three weeks on one training video—or pay ~$30 per month and crank out 10?

Synthesia Use Cases: Real Benefits, Real Results
I’ve seen HR teams save over 100 hours a month just by converting old Zoom training sessions into modular AI videos.
💬 “We used to spend 2 weeks training someone new—now it’s 2 days. Synthesia is the best investment L&D has made in 5 years.” – Trustpilot Reviewer
💬 “The multilingual support helped us onboard new hires across 3 continents, fast.” – G2 User
Whether you’re dealing with onboarding, compliance, or customer success training, Synthesia can shave days—sometimes weeks—off your content workflow.
What About Competitors Like Pictory or DeepBrain?
I’ve tested them all. Truth?
They’re solid—but not built from the ground up with onboarding and training in mind.
Pictory is great for turning blogs into video summaries.
DeepBrain is focused heavily on chatbot avatars.
But Synthesia?
It gives you more avatar options, voice/language support, branding control, and usability for employee-focused content.
If your primary need is onboarding and training…
Skip the fluff. Go with Synthesia.
Any Downsides You Should Know?
No tool is perfect. Here’s the honest scoop on what to expect:
- 🤖 AI avatars are realistic—but not 100% indistinguishable from real humans. Gestures are a bit limited.
- 🔄 High video demand? Synthesia’s credit system might add up quickly if you’re producing dozens of videos monthly.
- 🕐 Render time depends on volume. It can take 10–20 minutes per video in high-traffic hours.
That said, these are minor trade-offs considering the time, money, and sanity saved.
Is Synthesia Worth It for Training and Onboarding in 2025?
If you’re someone who…
- Builds onboarding videos regularly
- Needs to localize training across languages
- Wants branded content without hiring designers
- Values speed, consistency, and ROI
Then yes—Synthesia isn’t just worth it. It’s likely your best option for 2025 and beyond.
