AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
AI-native browser that understands your context and runs agent tasks
Reference tabs, tab groups, local files, highlighted text, whole pages, or screenshots as context with a single @ or one click, so you never copy-paste background material again.
Describe a routine in plain language and Tabbit's agent opens pages, fills forms, and carries out repetitive operations for you.
Choose among several leading models including DeepSeek, Kimi, GLM, MiniMax, Doubao, Qwen, and LongCat depending on the task.
Tabs are automatically grouped, categorized, and summarized in a vertical sidebar, making dozens of open research pages manageable.
