The desktop assistant gap
Why most AI desktop assistants fall short
They chat, but they do not execute
ChatGPT Agent and browser sidebars can suggest next steps, yet they rarely finish multi-step workflows across different websites.
They require yet another app
Manus and remote VM agents force you to leave your desktop environment. Tabbit lives in the browser, where your work already happens.
What you get
A desktop assistant that actually gets work done
Agent mode in parallel workspaces
Describe a task and Tabbit opens a dedicated tab group to research, fill forms, extract data, and deliver results while you keep working.
@ context without copy-paste
Reference open tabs, screenshots, PDFs, or Excel files directly in the omnibox. What you see becomes agent context instantly.
Reusable Skills
Save prompts and automations as Skills. Type / to rerun them, or browse the Skills plaza for community-built desktop workflows.
