Why DrLarz

Your AI shouldn't be trapped in one browser tab.

The smartest tools on earth are stuck behind a dozen logins, a dozen apps, and a dozen model names you're somehow supposed to choose between. DrLarz pulls it all into one assistant that follows you everywhere.

"I have a different AI app open on every device, and none of them remember anything.

DrLarz is one assistant — same voice on your phone, your desktop, and inside your own apps. Pick it up wherever you are.

"There are too many models. I never know which one to use.

You shouldn't have to. Just ask. DrLarz picks the right engine for each task automatically — fast for quick things, deep for the hard ones.

"Every AI service wants its own subscription and its own bill.

One DrLarz account covers it. One key, one balance, clear usage — across every device and every app you build.

How it works

One assistant. Every device. Every model — handled.

No model menus, no provider juggling. Just ask DrLarz, on whatever screen is closest.

Talk to it anywhere

Voice or chat on your phone and desktop, or right inside your own apps.

It picks the model

DrLarz routes each request to the right engine behind the scenes. You never choose.

One key, one balance

Top up once. Everything DrLarz does draws from the same simple balance.

You stay in control

Hard spending caps, per-key limits, and clear usage. Set a limit and it actually stops.

For developers

One API. Every model. No backend to manage.

Build DrLarz into your own product with the OpenAI-compatible API you already know. Use a DrLarz model name — we handle the rest.

client = OpenAI(
    api_key="sk_live_...",
    base_url="https://gateway.larzpay.com/v1",   # ← only change
)
client.chat.completions.create(
    model="drlarz-smart",                       # DrLarz picks the engine
    messages=[...]
)

What you get
