PDF extraction page limits and using your own AI key
50 on Free, 200 on Starter, 500 on Team and 1,000 on Pro extracted pages a month with Mammoth's own key · Updated 8 Nov 2026
Mammoth reads PDFs and images with AI. By default it uses Mammoth's own key, and the pages count toward your plan's monthly allowance of extracted pages; you can pick your workspace's own OpenAI key instead. The key is chosen at the top of the Review data import window (see Extract tables from PDFs and images).
Choose which AI key reads the file
The top of Review data import says which key reads the document. Only OpenAI keys can read PDFs and images.
- With no key of your own: "Reading with Mammoth's own AI key." and an Add your own key link, which opens Add External API Key to paste an OpenAI key (see Add your own AI provider key).
- With OpenAI keys in the workspace: Reading with and a menu. Pick Mammoth's own key or one of your keys; each shows its model, such as Model: gpt-4o. Add new key adds another.
If you change the key after an extraction: "Key changed. Run the extraction again to see the results."
| Key | What counts against it |
|---|---|
| Mammoth's own key (the default) | Your plan's monthly allowance of extracted pages. Over it: "Monthly AI usage limit reached. Contact support to extend." On a plan without it: "This feature is not included in your current plan." |
| Your own OpenAI key | Your OpenAI account's credit and rate limits. Mammoth's page allowance isn't used. |
Page limits for PDF extraction
| Limit | Value |
|---|---|
| Pages per document | Mammoth extracts up to the first 2,000 pages |
| Monthly extracted pages with Mammoth's own key | 50 on Free, 200 on Starter, 500 on Team and 1,000 on Pro. A run is charged only when it delivers tables |
| Long documents | If an extraction takes longer than Mammoth can wait, it says the extraction may still finish and to reopen the file in a few minutes |
See Limits and quotas.
Troubleshoot page and quota errors
| Symptom | Cause | Fix |
|---|---|---|
| Some pages were not extracted | Some pages had more data than your plan can extract | Use the Upgrade your plan link in the message |
| "Monthly AI usage limit reached. Contact support to extend." | Your monthly page allowance is used up | Wait for the next month, contact support, or use your own OpenAI key |
| "Your key has insufficient quota, no tables could be extracted. Please update your key or check your usage limits." | Your own AI key ran out of quota (the message says if some tables came first) | Update the key or check your limits with your AI provider, then extract again |
