Definition
From question to an evidence-backed report
A deep research AI tool should show its work: the question, source trail, extracted claims, and final synthesis. Tabbit keeps those layers visible in one evidence workbench instead of hiding them behind a chat answer.
Unlike chat-only research in ChatGPT or Gemini, Tabbit keeps live source tabs beside the report. You can inspect a claim, open its source, interrupt the run, and save the complete trail for later.
Four-phase workflow
How Deep Research Works in Tabbit
The same Plan → Search → Reason → Report loop used by leading AI research tools—built into the browser you use every day.

Tabbit navigates the live web—news, docs, forums, PDFs—filtering noise and prioritizing authoritative sources.
Reason
Cross-source synthesis: compare claims, resolve conflicts, and attach inline citations to every key finding.
Report
Deliver a structured brief you can export, share, or save to your knowledge-base bookmarks—full text preserved forever.

Why a Deep Research Browser Beats Chat-Only Tools
Deep research locked inside a chat window cannot see what you see. Tabbit closes that gap.
Parallel tab groups
Research runs in its own group while you email, code, or read—true multitasking, not context switching.
@ live page context
Cite open tabs, screenshots, PDFs, or bookmarks in one Omnibox prompt—no copy-paste relay.
Permanent knowledge base
Every report and source saves full-text to bookmarks. Pages go offline; your research does not.
