Shortwave's AI assistant uses a daily quota system. Each request consumes a portion of your quota depending on which intelligence level you use and how long the conversation is.
Shortwave offers four intelligence levels, each powered by a different AI model:
| Level | Best for | Quota cost |
|---|---|---|
| Basic | Simple tasks like marking done or labeling | Free (does not count toward quota) |
| Standard | Everyday email tasks, summaries, and short replies | Moderate |
| Advanced | Complex analysis, detailed writing, and multi-step tasks | High |
| Expert | Extended reasoning, deep research, and long documents | Very high |
You can switch intelligence levels by clicking the model selector at the top of the AI chat panel. Your selection stays active until you change it.
Your quota resets every 24 hours. There is currently no way to purchase additional quota or top off mid-day.
If you're consistently hitting your quota limit, consider upgrading to a higher plan for a larger daily allowance, or adjusting your usage patterns with the tips above.
