ChatGPT inside Google Sheets and Excel, with no API keys required
Use AI in any cell through a simple function — no API keys, no external chat window, no copy-paste between tabs.
Drag a single prompt down a column to process thousands of rows, with identical queries cached so you are not charged twice for the same work.
Summarise, rewrite, extract and classify long bodies of text such as surveys, articles or social posts into clean structured columns.
Generate ad copy, keyword lists, SEO content and campaign structures directly from your sheet's own data.
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.
