Product studio by Exerevno · Day Old is live

We build software that quietly does the work.

Exer-labs is the app studio from Exerevno, a New Zealand AI consultancy. Our first app, Day Old, turns the AI-news firehose into a short daily brief — every claim linked to its source.

What we've built

Apps from the lab

Each one starts with a real, repeated problem — then we build the smallest thing that solves it well.

Day Old

Live

A daily brief of the AI news worth your time. Day Old reads the firehose so you don't have to — concise, sourced summaries you can skim over a coffee, with every claim linked to its source.

The next app

Coming soon

We're prototyping the next tool in the studio — same idea: a sharp app that takes one tedious thing off your plate.

About the studio

A small studio that ships.

Exer-labs is the product arm of Exerevno Ltd, an AI consultancy. Consulting taught us where AI actually helps — and where it just adds noise. The lab is where we turn those lessons into real, standalone products.

No hype, no half-finished demos. Just useful apps, built carefully and kept maintained.

Need hands-on AI help in your business? That's our parent company, Exerevno consulting.

Useful over impressive

If it doesn't save you time or effort, it doesn't ship. Every feature earns its place.

Honest by default

Sourced, traceable, and clear about what the software can and can't do.

Fast and focused

Small apps that do one thing well beat sprawling platforms that do nothing well.

Built to last

We maintain what we launch. An app from the lab is looked after, not abandoned.

Start with Day Old.

See the kind of thing we build. Day Old is free, takes a few minutes to read, and is updated every morning.
