Fair Use Policy
Last updated:
Calven plans are priced on three things: products, tracked competitors, and transcripts and documents. The Individual plan also sets a monthly number of win/loss interviews. Everything else in the product is included in your plan without a meter: AI voice interview time, chat with your agents, the Slack app, and the MCP server.
This policy exists so that stays true. It sets limits that a team using Calven for its own product marketing will not reach. It is a protection against abuse, not a usage tier. Crossing a limit costs nothing, and we will never ask you to buy more of any of these.
1. What the limits are
Limits apply per workspace and per calendar month (UTC). Your usage is shown under Settings and Billing in your workspace.
| What we count | Individual | Professional | Enterprise | Trial |
|---|---|---|---|---|
| AI voice interview time. Total time of AI-conducted interviews connected in the month, including test calls. Each call ends after 30 minutes. | 10 hours | 40 hours | 100 hours | 10 hours |
| Slack messages. Messages your team sends to the Calven Slack app. | Not on this plan | 10,000 | 30,000 | 2,000 |
| Chat messages. Messages you send to agents in the Calven app. | 2,000 | 10,000 | 30,000 | 2,000 |
| MCP tool calls. Tool calls from AI clients connected through the Calven MCP server. | 10,000 | 50,000 | 150,000 | 10,000 |
Trial workspaces use the Trial column regardless of the plan they are trying. Enterprise workspaces with Expansion Packs use the Enterprise column. If your team genuinely needs more, tell us and we raise the limit at no cost.
2. What happens if you get close
If a workspace approaches a limit, we contact the workspace administrators to understand the usage. In almost every case the use is real and we raise the limit.
If usage passes a limit and we cannot reach you, or the pattern looks automated, we may slow down or pause that one feature for the rest of the month. Nothing else in the workspace is affected and nothing is deleted.
Deliberate, repeated, or clearly abusive use is a breach of the Terms of Use and can lead to suspension or termination under the Termination section of the Terms.
3. Automation and bots
Using Calven from your own scripts, from AI clients over MCP, or from Slack workflows is fine at the pace a team works. What is not fine:
- scripted loops that send messages, tool calls, or agent runs faster than a person would, or that retry until something succeeds;
- sharing one workspace across several companies, or reselling access;
- using AI voice interviews for anything other than interviewing your own buyers, customers, and prospects;
- using the research agents as a general web scraping or proxy service;
- extracting output at scale to build datasets or train models;
- running the same trial more than once for the same company.
Short-term rate limits also apply to keep the Service responsive for everyone. They are not part of this policy, and a team working at a normal pace never sees them.
4. Changes
We only lower a limit with 30 days' notice by email to workspace administrators. We may raise a limit at any time.
