Turn documents into source-checked explainer videos

What is Leap?
Leap turns documents into narrated explainer videos. Upload a PDF, Word file, PowerPoint, Markdown or text file, or a recorded lecture, and Leap writes the script, with every spoken line tied to a quote and page in your source. Leap checks the numbers and quotes against your document before anything is recorded. You approve the script, then a storyboard of pictures, then the finished video. Styles: whiteboard, motion graphics and cartoon. Export an MP4, captions (VTT or SRT), a SCORM 1.2 package for your LMS, or slides and a PDF of the stills. Built for instructional designers, L&D and compliance teams, and educators. Invite-only beta with 120 free credits.

There's two things you can do to earn sweat coins you can either start walking or you invite a friend for five sweat coins and that created quite a lot of that intrinsic virality where we made the earning sweat coins essentially earning sweat coins is the user experience.
Solve Cold Start by Embedding the Referral Mechanism Into the Core User Journey
Sweatcoin's referral program wasn't a separate screen or a growthy pop-up — it was one of two primary actions on the core 'earn' screen, right alongside walking. This made inviting friends feel like a natural part of the product, not a growth mechanic bolted on. Once Anton had the currency (the coin) to fund referral rewards, growth could be self-sustaining. The structure transferred from being stuck at 40K users to growing at 300/day within months.
They shame you and then they just like reward you excessively for every single move. But they can do this because with language learning you can complete the task inside the app and you can complete it quickly. You can't get a better night's sleep in five minutes in the grocery store line.
Duolingo's shame-then-reward loop works because the task is completable inside the app in 3 minutes — yours may not be
Paloni explains why copying Duolingo's engagement mechanics fails for most health and wellness apps: Duolingo's loop works because the entire beneficial action — closing a language lesson — happens inside the app in 3-5 minutes. The notification shames you into opening, and then fast in-app completion delivers immediate reward. Health outcomes like sleeping more, exercising, or reducing stress cannot be accomplished in-app. Building Duolingo-style streak pressure around actions that require multi-hour offline behavior creates shame with no attainable reward.
There's a play for whatever you're stuck on.
