Understudy vs Lessonly
You can't train what you haven't captured.
The Gap Before Training
Lessonly (now Seismic Learning) is a training delivery platform. You build lessons, assign them to people, track completion. For companies with established training programs, it's solid.
But there's a step everyone skips: where does the training content come from?
Usually it's one person — a manager or L&D coordinator — sitting down to write lessons from scratch. They interview subject matter experts, try to capture everything, and inevitably miss the nuances. The resulting lessons cover 80% of what people need. The other 20% — the hard-won edge cases, the "here's what you actually do when things go sideways" — stays in people's heads.
What Understudy Does Differently
Understudy is the step before Lessonly. It's how you get knowledge out of your experts' heads in a way that's complete, structured, and actually useful.
Instead of a manager spending days interviewing people and writing lessons, Understudy runs the interview itself. AI asks the probing questions. It catches gaps. It pushes past "well, you just kind of know" to get the specific, teachable details. The output is a structured playbook that you can turn into Lessonly lessons, onboarding docs, or whatever format works for your team.
The Workflow
With just Lessonly
Schedule interviews with experts → spend hours writing lessons → review cycles with SMEs → publish lessons that cover the basics → new hires still need months of shadowing for the real stuff
With Understudy → Lessonly
Expert has a 15-min Understudy conversation → gets a complete playbook with edge cases → convert to Lessonly lesson → new hires get the real knowledge from day one
Feature Comparison
| Understudy | Lessonly | |
|---|---|---|
| Primary purpose | Extract & capture knowledge | Deliver training lessons |
| How content is created | AI-guided conversation | Manual lesson builder |
| Time to create a module | 15 minutes | Several hours to days |
| Edge case coverage | AI probes for gaps | Only what the author includes |
| Quizzes & tracking | Not the focus | Built-in assessments & analytics |
| Team size | 1–500 | 50+ (mid-market focus) |
| Pricing | Free early access | Custom pricing (typically $300+/mo) |
The Bottom Line
Lessonly delivers training. Understudy creates the raw material that makes training actually good.
If you already have great training content → Lessonly is fine on its own.
If your training content is thin because nobody has time to write it → Understudy fills that gap in minutes, not weeks.
