PM tools created email dumps, not email integrations. Attachments get lost. Plugins break. You're still copy-pasting. Casso fixes this. Forward an email, get a real task with AI summary, deadlines extracted, attachments saved, and replies as comments. Need to update that task? Add ticket:xxxxx to the subject. Same task, new info, no duplicates. Works with any email client. Jira, ClickUp, Asana, Monday. No plugins, agents, n8n, zaps, or bugs.
