Built for problems that shouldn’t be this difficult.

Each Orelva product starts with the same question: why is something this simple still so frustrating?

German Letter Decoder

German bureaucracy, translated into plain language.

We’re exploring a tool that helps people understand German official letters — what they mean, what the sender wants, important deadlines, and what to do next.

Concept sketch

  • 01An official letter arrives
  • 02What it means, in plain language
  • 03Deadlines and what to do next

Not built yet. Still deciding what the smallest useful version is.

Researching

Experiment 02

A small problem we’ve decided shouldn’t exist anymore.

Researching

Experiment 03

Finding the simplest possible solution to another unnecessarily difficult task.

Have a frustrating problem?

The best Orelva products often start with something people complain about every day.

Suggest a problem

Software shouldn’t require a tutorial, a sales call, and a €49 monthly subscription just to solve a five-minute problem.

We believe some of the best software products do one thing exceptionally well.

Focused

One problem at a time.

If a product needs a 40-minute onboarding session, we’ve probably made it too complicated.

Useful

Value before features.

We care more about whether a tool saves you ten frustrating minutes than whether it has fifty features.

Fair

Pricing should match the problem.

Not every useful piece of software needs another monthly subscription.

Human

Technology should disappear.

You shouldn’t need to understand how the technology works to benefit from it.

Chat to PDF

Some conversations deserve better than screenshots.

Turn an exported WhatsApp conversation into a clean, structured PDF record — complete with participants, dates, timestamps and the conversation itself.

Structured

Messages, participants, dates and timestamps are organised into a proper document.

Private

Your conversation is processed locally rather than being sent through the payment system.

Preview first

See the first 5 pages before deciding whether to unlock the full document.

One-time

Unlock the complete PDF for €2.99. No subscription.

See it before you pay.

Generate the first 5 pages of your PDF for free. If it looks right, unlock the complete document.

Your conversation stays on your device.

Chat to PDF processes your exported conversation locally to create the document. Your chat content isn’t sent to our payment system.

How it works

Preview — example conversation

Export your WhatsApp chat

In WhatsApp, open the conversation and use Export chat. Choose “Without media”. You get a plain text file.

Chat to PDF formats conversation exports into readable documents. It does not verify the authenticity of conversations or determine legal admissibility.

The lab

Find the friction.
Remove the friction.
Ship.

01 — Notice

We look for repetitive, confusing or unnecessarily difficult everyday problems.

02 — Simplify

We reduce the problem to the smallest useful software experience possible.

03 — Ship

We put it in people’s hands, learn from real usage, and improve what matters.

We’re not trying to build everything. We’re trying to build the small things you wish already existed.

One useful product at a time.

Orelva Labs is an independent software studio.

We build small, focused software products for problems that are frustrating enough to deserve better solutions but often too specific for large software companies to care about.

Some tools may use artificial intelligence. Some won’t. What matters is whether the technology makes the problem meaningfully easier.

Useful beats impressive.
