Credits & Usage
A credit is the unit UniMatrix bills work in. One balance covers everything — tutoring, code, files, images, live sessions, voice — so you never have to think about which meter you are on.
Where your balance comes from
Section titled “Where your balance comes from”| Plan | Allowance | Resets |
|---|---|---|
| Free | 50 credits | Every day at 00:00 UTC |
| Standard | 1,700 credits | Every billing cycle |
| Premium | 5,000 credits | Every billing cycle |
| Sovereign | 25,000 credits | Every billing cycle |
Members of an organisation spend their own credits first, then the organisation’s shared pool.
What things cost
Section titled “What things cost”Conversation
Section titled “Conversation”Chat replies are metered by length, per plan. A one-line answer costs about one credit; a long, worked explanation costs more, up to a ceiling set by your plan. That means a short question is cheap on every plan, and only the answers that genuinely do more work cost more.
| Action | Cost |
|---|---|
| Reply on SPARK (Free) | from 1 credit |
| Reply on NOVA / ORACLE (paid) | from 3 credits |
| Spoken reply (voice on) | +2 credits |
| Attaching a file to a message | 3 credits per file |
Attachment limits per message: 4 on Free, 10 on Standard, 20 on Premium and Sovereign.
Files, decks and images
Section titled “Files, decks and images”Built files are charged by how much was actually built, not by a flat fee — a two-page document and a forty-page one are not the same job. Cost is a base plus a per-unit amount, where a unit is a page (or a slide, for a deck) and dense text counts even on few pages.
| Build | Base | Per extra unit |
|---|---|---|
| Text / Markdown | 2 | 2 |
| HTML | 4 | 2 |
| Word document (DOCX) | 6 | 3 |
| Spreadsheet (XLSX) | 6 | 3 |
| 8 | 3 | |
| Slide deck (PPTX or PDF) | 12 | 3 |
| SVG | 4 | 2 |
| PNG image | 5 | 2 |
| Layered PSD | 8 | 2 |
Connector actions
Section titled “Connector actions”| Action | Cost |
|---|---|
| Draft an email | 2 credits |
| Send an email | 5 credits |
| Save a file to Google Drive | 1 credit |
| Create a calendar event | 2 credits |
Live sessions
Section titled “Live sessions”| Action | Cost |
|---|---|
| Hosting a chat session | 3 credits / minute |
| Extending an ended session | 4 credits / minute |
| Slide outline | 5 credits |
| Slide image | 10 credits |
| Slide diagram | 3 credits |
| Synapse live video | 105 credits / minute |
Only the host is charged for a session. Joining one is free.
Seeing what you have spent
Section titled “Seeing what you have spent”Settings → Credits shows your current balance, when it next resets, and a history of what has been spent and on what. Every charge is recorded against the action that caused it, so a surprising number always has an explanation attached to it.
When you run out
Section titled “When you run out”Actions that cost more than you have left are refused before any work starts, with a message saying so — you are never charged for a half-finished answer. On Free the balance returns the next day; on a paid plan it returns at the start of the next cycle, or you can upgrade for a larger pool immediately.
If an action fails
Section titled “If an action fails”A charge that doesn’t deliver is refunded. Some actions are paid for before the work is attempted — hosting a session, sending an email through a connector, saving a file to Drive, creating a calendar event. If the work then fails for any reason, including the other service timing out, the credits go back. You are charged for what you got.
