Viral App Labs

Research

Specialized models, built in-house.

We don’t stretch one model to do everything. We build a focused model for each audience we serve, and the product that puts it in their hands.

Our approach

A model is only as good as the problem it understands.

Each Viral App Labs model is trained on the patterns of a specific domain (personal finance, short video, the App Store), so it reasons like an expert in that world. Smaller, sharper, and private by default beats big and generic.

The lineup

Four models. Three products.

In development

Surge 2

The model that understands what goes viral.

Surge family · For content creators

Powers ReelTok

Our flagship creative model. Surge 2 studies the patterns behind breakout videos (hooks, pacing, sound, and trend timing), then turns a rough idea into a post engineered to travel.

  • Predicts a concept's viral potential before you film
  • Writes hooks, captions, and on-screen text in your voice
  • Reads trends across TikTok and Instagram in real time
  • Recommends the cut, sound, and posting window that wins
In development

Surge Lite

Surge speed, on every device.

Surge family · For content creators

Powers ReelTok

A distilled version of Surge built for instant, on-device suggestions while you create. Surge Lite keeps the feedback loop tight so the tool never interrupts the flow.

  • Real-time, low-latency suggestions as you edit
  • Runs efficiently for fast everyday drafting
  • Smart trims, captions, and hook variations on demand
Available

Onset

Your money, figured out. Right on your phone.

Onset family · For consumers

Powers Gravity

The on-device model behind Gravity. Onset reasons about your charges, free trials, and renewal timing entirely on your iPhone (no bank connection, nothing leaving the device) to find the money you're losing and show you exactly what to do about it. Built to scale from subscriptions to your whole budget.

  • Finds recurring charges, free trials, and forgotten subscriptions
  • Reasons about your spending to surface real savings
  • Runs entirely on-device: no bank connection, nothing leaves your iPhone
  • Built to grow from subscriptions into full budgeting
In development

LemurOS

An operating model for shipping apps.

LemurOS family · For developers

Powers AppLemur

The model powering AppLemur. LemurOS turns the noise of the App Store into a clear read on your market (keywords, competitors, and demand), so indie developers make decisions with data instead of guesswork.

  • Surfaces the keywords real users search for
  • Tracks competitor rankings and positioning shifts
  • Translates ASO signals into concrete next moves
  • Built for indie developers, not enterprise dashboards

Built into products you can use.

Our research doesn’t live in a paper. It ships inside Gravity, ReelTok, and AppLemur, the products that put each model to work.
