[🔬 onboarding dissection] Submagic top 3 activation moves

What is Submagic?

Submagic turns long-form video into subtitled short-form clips.

I walked through their onboarding twice (once with a sample video, once with my own). Here are the 3 moves I would steal if I were running activation for a PLG product today:

1. live preview while tweaking options
2. co-founder welcome video with a real WhatsApp number
3. email notification prompting clip discovery

TOP 1 — the promised<>experienced value gap is really short

Just seconds after signup, the user lands in the editor, whether after uploading a video of theirs or by picking the provided sample video. As they change fonts, colors, or animation styles, the preview updates in real time and you see Submagic's...magic.

That's it. That's the move.

It's the earliest possible proof that the product does what the landing page promised, and because there is a sample video for testing the tool, that proof happens before the user has committed to anything real. No file uploaded, no time invested. The gap between "I wonder if this works" and "okay, I can see it working" closes in seconds.

What's brilliant here: the user may be curious or even excited about using the product, but they may not have a video at hand right now. To avoid killing the momentum (and potentially risking the user to simply forget about Submagic and never return, or go to a competitor product), Submagic provides a sample video for the user to try the product on. Low effort, low risk.

[note to self: this makes me think of Fathom's onboarding with their first test call. I should review their onboarding]

TOP 2 — co-founder welcome video with a real WhatsApp number

The sample video provided for users to test Submagic is actually a welcome message from one of the co-founders.

Not only does this message help build human-to-human connection, make the user feel welcomed and state Submagic's mission (those 3 already build solid trust and humanize the product), it also goes a step further with the co-founder sharing their own WhatsApp number for support, to "be there for their users". Massive trust builder!

The timing is also super important.

This message hits at the moment the user is most uncertain: they've just signed up, they haven't seen results yet, and their "guard" is up.

The effect: this stops feeling like "a SaaS tool I'm evaluating" and starts feeling like "someone who wants me to succeed." This is crucial because users who feel cared for are more forgiving of friction/small bugs and more motivated to push through to their first meaningful win.

What I love about that move is trust isn't only built by polish. It's built by delivering emotions, feelings, and making users feel seen, valued and cared for. This is powerful and, imho, too rare in digital products.

TOP 3 — email notification prompting clip discovery

After the user uploads a real video, processing takes a few minutes. Long enough for attention to drift. The user may close the tab, and move on with their day and next priority. Life keeps happening outside our apps.

But then the email hits: your clips are ready.

This email is doing 2 jobs at once:

First, it closes the uncertainty loop opened by the upload. The user left the product not knowing if anything would actually come back. The email confirms something did.

Second, it re-activates a user who may have drifted. The tone turns the first real output into a micro-celebration: not "your task is complete," but "come see what we made with your video" This opens a new curiosity loop right as the previous one resolves, pulling the user back in at exactly the moment they have something worth returning to.

The Submagic team acknowledges the fact that users won't put their lives on pause waiting for their (long) videos to be processed and their clips to be ready. They also understand the power of off-platform notifications as nudges to get users back in the product, not for the sake of it but when there's truly something valuable and meaningful for users to discover.

How these 3 moves work together

Each one is doing the same underlying job: reducing the time between belief and confirmed belief. Let me explain real quick:

If a user signs up, it means:

• they believe the product could be useful to them
• they believe the product should be easy to use

The goal of onboarding is to get users to confirm those internal beliefs:

• "this actually works and is useful to me"
• "this actually is easy to use"

If one of those 2 beliefs breaks after session #1, i'd bet higher on that user churning and never coming again (as up to 60% of users don't give a product a second chance if they didn't experience meaningful value during their first session. Source: ProductLed) rather than sticking to your product.

So here's how those 3 activation moves reduce the time between belief and confirmed belief:

• move 1 compresses it by showing the product working before any commitment
• move 2 compresses it by making the user feel personally supported during the uncertainty
• move 3 compresses it by turning a waiting room into a return trip

If you're shipping onboarding this quarter, the question isn't "what do we need to teach the user?" It's "how fast can we make them believe?"

Submagic's answer: start before they've uploaded anything, show up as a human when doubt is highest, and treat every async moment as a chance to pull them back in.

I hope this was valuable.
