Theo limits
The message limits of Theo, the VitalSentinel AI assistant, the messages you see when you reach one, and what still works.
Theo, the VitalSentinel AI assistant, has limits on AI answers. The limits protect Theo against misuse. VitalSentinel can change the limits at any time without prior notice. This page lists each limit, the message that Theo shows for it, and what still works.
What has no limit
These parts of the Theo chat have no limit and work at all times:
- Answers to suggested questions.
- Other built-in answers, for example About this page and From your data.
- What does this page show? and What needs attention here?.
- The From the docs list while you type, and docs cards.
- Support tickets: Send to the team, Talk to the team and Write to the team.
Limits on AI answers
| Limit | Applies to | Message in the chat |
|---|---|---|
| AI answers each month | The workspace | "This workspace has used its AI answers for this month; they resume on the 1st. ..." |
| Messages in a short time | You | "You sent many messages. Try again in [number] minutes." |
| Messages each day | You | "You reached today's limit. Theo is back tomorrow." |
| One answer at a time | You | "Wait for the current answer to finish." |
| Length of one conversation | One conversation | "This chat is long. Start a new chat to keep answers fast." |
| Length of one message | One message | A counter, for example "1,950 / 2,000" |
AI answers each month
Each workspace has a monthly allowance of AI answers. The allowance depends on your plan:
| Plan | Theo AI answers a month |
|---|---|
| Free | 100 |
| Starter | 500 |
| Lite, Standard and Advanced | 1,000 |
The app does not show a counter. For all plan limits, see Plans and limits.
Only messages that reach the AI count. Suggested questions and other built-in answers do not count. One question counts once, also when Theo uses a stronger model for a deeper answer. The allowance starts again on the 1st of each month.
Limits for each person
Theo also limits how many messages one person can send in an hour and in a day. These limits count the questions that you type. Suggested questions do not count. When you reach a limit, Theo tells you when to try again.
Message and conversation length
One message can have up to 2,000 characters. Near the limit, the Ask Theo box shows a counter.
A conversation can have a limited number of messages. When a conversation is too long, Theo shows "This chat is long. Start a new chat to keep answers fast." Go back to the chat home and ask your question again there.
When AI answers are not available
When the AI cannot answer, Theo answers with built-in answers and docs cards. It also offers Send to the team. The answer starts with one line that tells you why:
| Line in the chat | Reason |
|---|---|
| "This workspace has used its AI answers for this month; they resume on the 1st. Built-in answers, the docs and sending a message to the team still work." | The workspace used all its AI answers for the month |
| "Verify your email to use Theo. Built-in answers, the docs and sending a message to the team still work." | Your email address is not verified |
| "AI answers are paused for now. Built-in answers, the docs and sending a message to the team still work." | VitalSentinel paused AI answers for now |
| "AI answers are unavailable right now. Built-in answers, the docs and sending a message to the team still work." | The AI service cannot answer at the moment |
| "AI answers are not available right now. Built-in answers, the docs and sending a message to the team still work." | AI answers are not available |
What to do when AI answers are not available
- If your email address is not verified, verify it. Then ask again.
- If the workspace used its AI answers, wait until the 1st of the next month, or send your question to the team.
- If AI answers are paused or unavailable, try again later, or send your question to the team.
Troubleshooting
Why does Theo say "You sent many messages"?
If you see "You sent many messages. Try again in [number] minutes.", you sent many questions in a short time. Wait the number of minutes in the message. Then ask again.
Why does Theo say "You reached today's limit"?
If you see "You reached today's limit. Theo is back tomorrow.", you reached your daily limit of AI messages. Built-in answers and the docs still work. Ask again the next day, or send your question to the team.
Why does Theo say "Wait for the current answer to finish"?
If you see "Wait for the current answer to finish.", Theo still writes an earlier answer. Theo writes one answer at a time for each person, also in another browser tab. Wait for the answer. Then send your message.
Why does Theo say "This chat is long"?
If you see "This chat is long. Start a new chat to keep answers fast.", the conversation reached its maximum length. Start a new chat from the chat home.
How many AI answers does my plan include?
The number of AI answers depends on your plan (100 on Free, 500 on Starter, 1,000 on Lite and higher). If the workspace used its AI answers, send your question to the team with Write to the team.
