Limits at a glance
Every concrete limit in BlockMind on one page — chat attachments, Free plan caps, trial terms, alert timing, Telegram, DeepDive, connections, and more.
One page for every hard number in the product. Each row links to the page that explains it in context.
| Limit | Value | Details |
|---|
| Files per message | 5 | Web chat |
| Size per file | 4 MB | Web chat |
| Supported types | PDF, DOCX, XLSX, CSV, JSON, Markdown, plain text, and images (PNG, JPEG, GIF, WebP) | Web chat |
You can also paste screenshots directly into the composer.
The Free plan is the classic platform — your agent doesn't run on Free.
| Limit | Value | Details |
|---|
| Trial length | 7 days ($0 today, card required) | Plans & pricing |
| Free weeks per account | One, ever — returning subscribers are charged from day one | Plans & pricing |
Alerts and monitoring are research, not financial advice — your agent flags what moved, but it will never tell you what to buy or sell.
