Document AI timeouts and message limits
Soft and hard timeouts for long document work, session usage limits, and current plan credit and upload numbers.
When processing large documents or long analysis requests, ISMS Copilot applies timeout and session usage controls so the system stays stable.
Timeout thresholds
Document AI requests have two timeout levels:
- 10-minute soft timeout: A banner may say the response is taking longer than expected. Processing can continue in the background; check back or retry if needed.
- 20-minute hard timeout: Requests past this are stopped. Split the work into smaller chunks and try again.
For very large documents, split into sections or upload fewer files at once.
Session usage limit
When you exhaust the current 4-hour UTC session window, the chat shows a limit card with a reset countdown and upgrade options. Free users also hit a 10 successful messages cap per window.
A separate conversation-size limit can appear when a single thread is too large (token budget). Start a new conversation to continue.
Quota by plan (mid-2026)
| Plan | Credits / 4h session | Uploads / month |
|---|---|---|
| Free | 10 | 10 |
| Essential (grandfathered) | 25 | 500 fair use |
| Plus | 50 | 500 fair use |
| Standard | 100 | 500 fair use |
| Pro | 250 | 500 fair use |
| Business | 500 | 500 fair use |

How to get more capacity
Use Upgrade in the top bar or on the limit card. Eligible free accounts can start a 7-day Plus trial. Manage billing later via the Stripe portal under Manage Subscription.
Tips to avoid timeouts
- Upload fewer files at once
- Extract only the sections you need from large PDFs or sheets
- Prefer specific prompts over open-ended "analyze everything"
- Start a new conversation per major topic
- Stay within file size limits documented on the upload page
