The idea

Every model you need, behind one balance in your wallet. You pay for the messages you send, and nothing else.

Every model,
labeled.

Each card says who can read your chat and what a million output tokens costs. Prices update live.

How it works

Three steps,
no forms.

  1. Step 1

    Sign once

    Your wallet is the account. One signature, with no email, password or gas.

  2. Step 2

    Top up

    Send ETH on Robinhood Chain or Base, or USDC on Base. It becomes a USD balance only your wallet can spend.

  3. Step 3

    Send

    Pick any model. You see its price before you send, and the exact charge after.

Pricing

The price you see is the price you pay.

No plans and no monthly bill. Every message is billed at the provider's cost plus a flat 20%, shown on every model before you send.

Privacy

Labeled, not promised.

Free

Free models

No training

Open models, paid

Routed only to providers that do not store or train on your prompts.

Provider

Claude, GPT, Gemini

Sent to the model's maker under their own policy. We say so on the model, every time.

No trackers and no ads. Your chat history is stored in your browser, not on our servers.

Developers

Change one line.

An OpenAI-compatible endpoint with streaming and tool calls. Your API key spends the same balance as the chat.

from openai import OpenAI

client = OpenAI(
    base_url="https://www.synaps.chat/api/v1",
    api_key=os.environ["SYNAPS_API_KEY"],
)

reply = client.chat.completions.create(
    model="deepseek/deepseek-chat",
    messages=[{"role": "user", "content": "gm"}],
)

The token

$SYNAPS

Coming on Pons. Synaps works today with ETH and USDC; the token will make your balance go further.

Bonus creditPay with $SYNAPS

Top up with the token and get more credit for the same amount. Rate announced at launch.

Public treasuryOn-chain

Top-ups and creator fees land in one wallet anyone can check.

PonsLaunch · TBA

The contract appears here automatically when the treasury wallet launches it, and on X (@onsynaps). Anything else is not ours.

$SYNAPS will be a utility token. It is not an investment and nothing here is financial advice.

Think out loud.
Pay per thought.

Free models need nothing. Premium ones need a wallet and $1.
