SynapseX Chat plans and pricing
This page lets you pick the right SynapseX Chat plan and change it without surprises. By the end you will know exactly what each tier costs, what monthly volume it buys, and what happens to your billing when you upgrade, downgrade or cancel.
These plans apply to chat.synapsex.ai only. They buy you nothing on the API platform, which is billed separately with prepaid credits — see API credits, spend limits and alerts.
How much does each SynapseX Chat plan cost?
| Plan | Price | Messages / month | Tokens / month | Custom agents | File storage | Seats |
|---|---|---|---|---|---|---|

| Go | $8/month, or $76.80/year | 5,000 | 500,000 | 3 | 4 GB | 1 |
| Plus (Recommended) | $20/month, or $192/year | 50,000 | 2,050,000 | 10 | 20 GB | 1 |
| Pro | $100/month (5x) | 200,000 | 10,000,000 | Unlimited | 100 GB | 1 |
| Business | $25/month per seat | Unlimited | Unlimited | Unlimited | 20 GB | Unlimited |
Notes on the table:
- Prices above are in US dollars. Some plans are priced separately in euros — Plus, for example, is €23/month. The pricing screen shows the currency you will actually be charged in.
- Yearly prices are the discounted annual amounts, not twelve times the monthly price.
- Pro has an in-card usage toggle with two settings, 5x and 20x. The 5x setting is $100/month; the 20x setting is $200/month. Pick the setting before you pay — it is billed as a different amount.
- Business is priced per seat: the $25 is charged for each team member, not once for the workspace.
You can verify all of this yourself against the live catalog:
curl -s https://chat.synapsex.ai/api/billing/plansIn the response, limits.messagesPerMonth, limits.tokensPerMonth,
limits.fileStorageGB and limits.teamMembers carry the figures above, and a
value of -1 means unlimited.
Which plan differences are actually enforced?
Be precise here, because it decides whether a plan change solves your problem.
Enforced today:
- Monthly message volume and monthly token volume. Exceeding either stops your chat turns until the next month.
- File storage in gigabytes.
- Seats (team members).
- Short-window rate limits, which rise with the tier.
Not a reason to upgrade: individual product features. SynapseX Chat does not gate capabilities by plan today, so choose your plan on volume, storage and seats — not on a feature list.
How do I upgrade my SynapseX Chat plan?
- Go to chat.synapsex.ai/upgrade , or open Settings → Billing and use the plan cards there.
- Choose the plan, and choose Monthly or Yearly. On Pro, also choose 5x or 20x.
- If you have a promo code, enter it. A valid code is applied to the amount shown before you pay; an invalid one is rejected and the form stays at full price.
- Pay with a card in the dialog that opens inside the app. You are never redirected to an external hosted payment page.
Your plan activates once the payment is confirmed. If you were already on a paid plan, the previous subscription is cancelled for you with proration, so you are not billed twice for the same period.
Buying the plan and billing period you are already on is refused with an HTTP 409 and the message “You are already subscribed to this plan.” Change the period or the plan first.
How do I downgrade to a cheaper plan?
A downgrade is scheduled, not immediate. You keep the tier you paid for until the end of the current billing period, and the cheaper price applies from the next renewal. The API returns the effective date, and the Billing tab shows a banner telling you when the change lands.
Upgrades cannot be processed this way — payment has to be collected up front, so an upgrade always goes through the checkout flow described above.
How do I cancel?
Cancellation is scheduled at the end of the current period by default. You keep your paid tier until that date, and then drop to Free when the period closes. The Billing tab shows the date the cancellation takes effect.
While the change is still pending — whether it is a cancellation or a scheduled downgrade — you can reverse it with the Resume action on the same banner. That clears the pending change and your plan continues as it is.
Where do I see my quota and what happens when I run out?
Open Settings → Billing. Alongside your current plan you get your month-to-date messages and tokens against the plan quota, plus an estimated cost for the month. Settings → Usage breaks token consumption down by model and by day.
When you exhaust the monthly quota, a chat turn is refused with HTTP 402 and
the code PLAN_QUOTA_EXCEEDED. Bursting too fast within a short window is
refused with HTTP 429 and a Retry-After header instead. Both are covered
in Limits and errors.
