Message Limits
Explain Like I'm Five
Think of messages like cups of water from a big jug. Each day, you get a jug with a certain number of cups.
When you chat with the AI, you pour some water. A short question? Just a tiny splash. A long conversation with a big document? That's like pouring several cups at once.
The longer your chat gets, the more water each new message needs — because the AI has to "remember" everything you've talked about so far.
Starting a new chat is like getting a fresh cup — you only pay for what's in that cup, not the whole conversation before it.
What is a "Message"?
One "message" from your daily allocation equals 16,000 tokens (~12,000 words).
A token is a small piece of text, roughly 4 characters or ¾ of a word.
How Usage is Calculated
Usage is based on the total context of an interaction:
- Your new prompt
- All previous messages in that chat (both yours and the AI's)
- Any uploaded documents in that chat
- The AI's response
Minimum Usage Rule
Every interaction consumes at least 1 message, regardless of size.
- Less than 16,000 tokens = 1 message
- 25,000 tokens = 2 messages
- 48,000 tokens = 3 messages
Example
Short chat: You ask "What's the capital of France?" — consumes 1 message (minimum).
Long chat with file: 20 exchanges + 10-page report (20,000 tokens) + conversation history (5,000 tokens) = 25,000 tokens total = 2 messages for that single prompt.
Tips for Effective Usage
- Start new chats frequently — resets conversation history
- Break up large documents — paste only the sections you need
- Be mindful of conversation length — long chats cost more per prompt
