openTBassignedNine modules. One support workspace.
Every module shares the same contacts, domain, team and API — so the pieces actually talk to each other.
One workspace, from first email to last release.
01 — Support Tickets
One inbox for every conversation your customers start
Emails to support@yourcompany.com, form submissions, portal requests and API calls all land as tickets with their own ID, owner and status. Your team works them in a realtime inbox built for speed.

02 — AI Agent
Answers from your Knowledge Base, approved by your team
When a customer writes, the AI agent searches your published articles and leaves a reply draft in the ticket with its sources. Your team reviews it, edits if needed and sends. If the answer isn't in your docs, it hands the ticket to a person.

03 — Broadcast
Email your customers from the same place you support them
Write product announcements and newsletters with a block editor, send them to a contact group and watch opens and clicks come in. Same contacts, same domain, no extra tool.
