Been away for a while, but honestly, have things changed?

Hey everyone,

Historically I founded @Nack AI, And it did quite well. But we eventually packed it up. So, I've been away from product hunt for 3 years since.

We integrated 10 wearable APIs so you don't have to

Something we kept running into across projects: wearable integration eats months and adds zero product value.

Every provider does things differently. Garmin sends XML. Whoop sends JSON but paginates differently than Oura. Apple Health needs on-device processing. Samsung has its own SDK. Different auth flows, different rate limits, different webhook formats.

Roll is one week old, and keeps on rollin!

Hello Roll fam.

Honestly blown away by the love, feedback, and overall vibes this past week. Didn t expect this.

A few updates that are now live, all coming straight from you shaping what Roll becomes:

Domain Packs: teach DecisionBox your industry in minutes

Domain Packs: Teach DecisionBox Your Industry in Minutes

Create, edit, import, and share AI discovery templates entirely from the dashboard.

TL;DR

Holy shit... I just automated sth I thought was impossible with AI: product tutorial videos

The problem at MindPal was pretty simple: we have hundreds of AI templates to share. We know videos of these templates work - some have gotten us tens of thousands of views. But actually making them was a total nightmare.
We tried everything. At one point, we even hired a freelancer, but the feedback loop was exhausting. It actually took longer to give feedback and wait for revisions than it did to just make the video ourselves. It was slow, expensive, and impossible to scale.
When we did it ourselves, it was a massive grind:
Record the screen of the behind-the-scene agent builder
Record a demo of the agent working
Write a script that didn't sound like a robot
Record a voiceover or an avatar
Spend hours editing everything together
If my co-founder or I were tired or busy, the videos just didn't happen. I assumed this was just the "manual tax" you had to pay for quality.
Last weekend, I got fed up and asked Claude if I could just automate the whole damn thing.
Turns out, I can.
So I spent the weekend cooking something - an internal AI SOP to turn any workflow URL (yes, from just a single URL) into a publish-ready use case video that passes all quality standards in ONE GO.
Here is the new setup:
Playwright: Records the screen and even moves the mouse like a human
@Claude by Anthropic: Writes the narrative based on our actual product info
@HeyGen: Creates the avatar and voiceover
@Remotion: Programs the entire edit - syncing everything into a final file
@Zernio + @Railway: Automatically publishes the video and saves the assets.
Now, I just give the system a URL and a finished video comes out. I don't even have to click "upload."
I just wrote a post sharing the full behind-the-scenes build, the architecture, and the logic behind of this AI video agent. Check it out here if you think this could be helpful for your company: https://mindpal.space/article/ai...

P/s: This is what I wake up to every day now

What our Pioneers have been saying about Clarity

We've had people tell us Clarity changed how they train, how they work, and how they sleep.

Most interestingly, people have told us that they are in fact drinking more caffeine, safe in the fact that they understand how the dose is being processed in their body and how it could be impacting their sleep if not timed correctly.

This isn't we invented anything. Because we put the science somewhere people actually use it - on their phone, in their routine, before the decision gets made.

Build your brand before your product, or launch first and reveal yourself later?

  1. I've always been on the personal brand side. More and more founders are building it now (sometimes even before the product is ready while it's still in development, before seed fundraising). The CEO builds their position so the product sells more easily at the official launch.

  2. But I have experience with people who built the product, scaled it, and only then did we discover who was behind it.

Honestly, with the first approach, I'd be concerned that people invest more in me as a person than in the product. People would idealise the founder and overlook the product's flaws (which could hurt development and constructive feedback).

+ I noticed the most common mistake that many people who started building a personal brand first, connected their product to their personal accounts (emails, social media, etc.) and started having a problem selling these things, because they cannot "give someone keys" to their personal profiles.
