Synthl
Five labs, one account

Every major AI model,
one balance.

Every flagship from every lab, plus video, music and a voice to read it — on one balance you top up when you feel like it. No five subscriptions. No paying for the months you barely log in.

A dollar is 1,000 tokens. They don't expire, and nothing bills you on its own.

What it does

Writing, pictures, video and whole websites

The same tokens pay for all of it. Pick a model per message, or let Synthl choose the cheapest one that can do the job.

Pictures

GPT Image 2.5, Nano Banana and Grok Imagine. New ones appear beside the pictures you already have, whatever shape they are, and each one shows what it actually cost.

Whole websites

Describe a site and watch it get built, ask questions about it without changing anything, then publish it to its own domain — hosted in your name, on your own free hosting account.

One balance

Everything on one account, nothing on a timer

No subscription per lab. No month wasted because you were busy. You buy tokens, they sit there until you use them, and they work on every model on this page.

Switch model mid-sentence

Ask Claude to draft it, GPT to check it and Gemini to read the 200-page appendix — in one conversation, on one balance.

Nothing renews behind your back

Tokens do not expire and nothing bills you on its own. Step away for three months and your balance is exactly where you left it.

You can see every token

Each answer, picture and clip shows what it cost, next to what the provider charged. No bundles, no mystery allowance.

Models

What you get access to

The current flagship from each lab, plus the cheap fast ones for everyday work. You pick per message, or let it pick for you.

  • Claude Fable 5.1, Opus 5.5, Sonnet 5.5 and Haiku 5.5 The careful writer. Fable is the strongest model here from 120 tokens/1M
  • Gemini 3.1 Pro, 3.8 Flash and 3.5 Flash-Lite Enormous memory, for very long documents from 360 tokens/1M

Tokens

Tokens, spent wherever you like

A dollar is a thousand tokens. They work across every model above, they do not expire, and nothing bills you on its own.

  • 5,000$5 a monthEnough to see whether you like it
  • 25,000$25 a monthA normal month for most peoplemost popular
  • 50,000$50 a monthRegular work, some video
  • 100,000$100 a monthDaily use across everything
  • 200,000$200 a monthHeavy use, video and all

A token is a tenth of a cent, and a dollar buys a thousand of them. Usage is charged at what the model provider bills plus 20%, so a request that costs the provider $0.10 uses 120 tokens — and your history shows both figures side by side. Prices in USD; you can pay in your own currency. Tokens don't expire.

One balance. Everything on it.

Stop paying five companies for the months you barely use. Put tokens on one account and spend them where the work actually is.

Card details go straight to Stripe and never reach us.
