AI drafts your email. You hit send. That's what TextForge does: it allows LLMs to safely read, search, download attachments from email AND compose replies / new drafts with attachments, signatures, and the like. But TextForge's real power comes from its webhooks and approval systems: 1. No emails are ever sent without your express approval - this helps prevent OpenClaw-style oopsies with email. 2. Approval requests can be sent via webhook to whatever your preferred messaging platform is: Slack, Discord, anything that accepts webhooks. You never need to open TextForge if you don't want to. 3. And if you want to build some really cool automations, TextForge even supports reply webhooks to help drive things like CRM automation if you wishb.
