# Limits and Quotas

Every number in one place.

## Plan limits

| | Free | Pro |
| --- | --- | --- |
| **Markdown documents** | 100 | 10,000 |
| **Uploaded images** | 5 | 10,000 |
| **Workspaces** | Unlimited | Unlimited |
| **Folders** | Unlimited | Unlimited |
| **Collections** | Unlimited | Unlimited |
| **Custom domains** | — | 1 |
| **Price** | Free forever | €4.99 / month |

Pro (see [04 Free and Pro Plans](/doc/b55abc0c-ac5d-44cb-b5a5-22b3cc04a69f)) starts with a **7-day free trial**, no card required.

## Size limits

| What | Limit |
| --- | --- |
| **Document body** | **500 KiB**, UTF-8 |
| **Imported markdown file** | 500 KiB each |
| **Image before processing** | 20 MB |
| **Image after processing** | Resized in-browser to max **1024 px** on its longest side |
| **Folder description** | 5,000 characters |
| **Document title** | 100 characters |

The 500 KiB body limit applies **everywhere** — the editor, the API, the MCP server, import, and the VS Code extension.

## Image formats

**JPEG, PNG and WebP.** Externally hosted images referenced by URL render in any format the browser supports, and do not count against your allowance (see [04 Images](/doc/1440e5da-c790-4b50-b24b-ebe4fd6e5a6c)).

## API and MCP limits

| What | Limit |
| --- | --- |
| **Rate limit** | **60 requests per minute**, per token **and** per authenticated user |
| **Over the limit** | `429` with a `Retry-After` header, in seconds |
| **Token scope** | Account-wide. No per-workspace or read-only tokens |

Because the limit is **per user** as well as per token, creating more tokens does not raise your ceiling.

## Version history retention (Pro)

Whichever comes first:

- **30 days**, or
- **the last 300 versions**.

With two adjustments:

- Documents over **100 KiB** keep only the **last 10 versions**.
- **Saves within a minute of each other are collapsed** into a single capture, so autosave does not shred history.

Free accounts accrue **no** history (see [06 Version History](/doc/9c6737c5-cb49-4eb8-83c8-d9a72e36fa3c)), and existing history is **removed** on downgrade.

## iOS app

See [02 iOS App](/doc/0a35e506-d632-4f07-aa6a-1d19a5ab3940) for the full feature list.

| What | Limit |
| --- | --- |
| **Minimum iOS** | 26.5 |
| **Search results** | 50, newest first |
| **Recent documents** | 5 |
| **Text zoom** | Base 17 pt, adjustable −5 to +10 |
| **Widget sizes** | Small only |

## n8n node

See [03 n8n Node](/doc/4fbc5f67-b6ac-4fed-8916-3ccfa4eb8632) for the full node reference.

| What | Limit |
| --- | --- |
| **Trigger deduplication** | The 10,000 most recent item IDs |
| **Pagination** | None — no Return All or Limit on any Get Many |
| **Retry on 429** | None — handle it in your workflow |

## Share links

| What | Value |
| --- | --- |
| **Share slug** | 64 random characters |
| **Revocation** | Immediate and permanent; a new link is generated on re-enable |

## What has no limit

Worth noting, since these are where other tools charge:

- **Workspaces, folders, folder depth, and collections** — unlimited on both plans.
- **Share links and comments** — unlimited on both plans.
- **Encryption** — unlimited on both plans.
- **Readers** of a shared document — unbounded; they need no account.
- **Import and export** — no cap beyond your document allowance.

## The one you will hit first

On Free, it is **5 images**, well before 100 documents. Images are the practical reason to upgrade for most writers; the document cap is generous enough that many people never approach it.
