Get started with SynapseX

SynapseX is an AI platform with four surfaces, and you do not have to learn all of them. Pick the one that matches what you want to do, follow one quickstart, and you will finish with a real, observable result — a first answer in the browser, an agent editing your own repository, measurement counts from a quantum circuit on your laptop, or a completed API call.

Which SynapseX quickstart should I start with?

SynapseX CLI — about 2 minutes. Ends with real measurement counts from a Bell state simulated on your own machine. No account, no network.
SynapseX Chat — about 2 minutes. Ends with an answer about a document you attached, from the model you picked.
Platform API — about 5 minutes. Ends with a completed OpenAI-compatible chat completion returned by https://platform.synapsex.ai/api/v1/chat/completions.
SynapseX Desktop — about 10 minutes. Ends with a reviewed diff of a change the agent made inside a project you opened from your own disk.

What do I need before I start?

Path	What you need first
CLI (simulator and local runner)	Nothing at all — no account, no network, no credits
CLI (AI models)	A SynapseX account, connected with `synapsex-code providers login`
Chat	A SynapseX account — sign in at chat.synapsex.ai
Desktop	A SynapseX account, approved from your browser during setup
Platform API	A separate account at platform.synapsex.ai , plus credits

Two things are worth knowing before you choose:

Chat and the Platform API are separate products with separate accounts. An account on chat.synapsex.ai gives you nothing on platform.synapsex.ai, and the reverse is also true. Their credits are different units and cannot be moved between them.
chat.synapsex.ai has no self-serve email and password signup. The sign-in page shows an email and password form, but that form only works for an account that already exists. To create an account, use Continue with Google. The Platform API at platform.synapsex.ai does have a normal registration form.

The fastest way to a real SynapseX result

This is the shortest path on the whole site: no account, no credits, and it works with your network cable unplugged. Install the CLI:


curl -fsSL https://synapsex.ai/install.sh | sh

Save this circuit as bell.qasm:


OPENQASM 2.0;
include "qelib1.inc";
qreg q[2];
creg c[2];
h q[0];
cx q[0],q[1];
measure q -> c;

Run it on the CLI’s built-in statevector simulator:


synapsex-code lab run bell.qasm --sim --shots 100 --seed 7

You get real sampled measurement counts:


mode=sim (local, off-ledger, $0)  file=bell.qasm
qubits=2  shots=100
counts:
  11  57  (57.0%)
  00  43  (43.0%)

Only 00 and 11 appear, in roughly equal proportion — that is the entanglement in a Bell state, computed on your own machine. The full walkthrough, including the simulator’s real limits, is in the CLI quickstart.

Want the mental model first?

If you would rather understand how the surfaces, accounts, keys and credits fit together before installing anything, read How SynapseX works, then come back and pick a quickstart.
