An AI-powered visual workspace where teams think, plan, and build together
An infinite multiplayer board where cursors, comments, and live editing let remote and hybrid teams work in the same space simultaneously.
Docs, Tables, Slides, Kanban, and Timelines live alongside freeform drawing so a workshop can turn directly into a structured plan.
Generate diagrams, tables, and summaries, remove image backgrounds, and connect external AI assistants through the MCP server.
6,000-7,000+ templates for brainstorming, workshops, roadmapping, and process mapping give teams a running start.

Antispam service that keeps junk mail, phishing and viruses out of every inbox
Works with iPhone, Android, Mac, PC, Office 365 and general IMAP/POP accounts, so one filter protects every device that reads the same mailbox.
Every new message is analysed before delivery, and suspicious senders, malicious links and infected attachments are stopped instead of reaching you.
Each time you mark something as spam or confirm it is legitimate, the filter learns your preferences and gets more accurate over time.
Held messages are not lost. You can open your Spamdrain account, inspect what was blocked, and release false positives with a click.
