# Pricing

> Usage-based pricing for the Visk MCP server

Usage is metered in **credits**, drawn from the same balance as the Visk app — your plan's monthly allowance plus any top-ups. Manage your plan at [visk.com](https://visk.com).

Credits are charged per slide: what a session costs comes down to how many slides you write and how many you read. New accounts get 200 credits free, enough to build around 100 slides.

| Operation | Price     | What counts                                                                                                                           |
| --------- | --------- | ------------------------------------------------------------------------------------------------------------------------------------- |
| Write     | 2 credits | Authoring or editing a slide's content. Charged only once per session for each slide, so iteration is free.                           |
| Read      | 1 credit  | Pulling a slide's HTML or taking a screenshot. Charged once per session for each slide, and upgraded to a write if you later edit it. |

Charges never stack. A slide is billed at **the highest tier you touch**, so reading a slide and then editing it costs 2 credits in total, not 3.

Opening a presentation is free: the agent receives a markdown summary of every slide as grounding, so it can orient itself across a large deck and charge you only for the slides it actually works on.

**Cost formula for a deck:**

```text theme={null}
total cost = (2 × slides written) + (1 × slides only read)
```

## What a credit costs

There are two ways to get credits:

* **A subscription** grants a monthly allowance that refreshes each billing period.
* **Credit packs** are one-off top-ups, including your signup grant and any bundles you buy.

Current plan and pack prices are on [visk.com](https://visk.com) — a 10-slide deck costs 20 credits, roughly \$0.50 on a subscription.

## Worked examples

| Session                                                    | Cost       |
| ---------------------------------------------------------- | ---------- |
| Author a 10-slide deck and polish it                       | 20 credits |
| Edit 3 slides of an uploaded deck, screenshots included    | 6 credits  |
| Read one slide as a style reference, then add 2 new slides | 5 credits  |
| Restyle the theme of a 50-slide deck (CSS or layout edit)  | 2 credits  |

<Note>
  * **A session is one continuous editing session on the same presentation**, lasting up to 24 hours. Reads and writes are charged once per slide within it.
  * **Failed calls are never charged.** Charges apply only when an operation succeeds.
  * **Running out of credits blocks further reads and writes**, but you can still export the deck you have.
