GPT Book Club vs AI Excel Bot

GPT Book Club was a browser-based reading companion that let you ask questions of popular nonfiction titles and get answers pulled from chapter summaries, quotes, and FAQ-style guides. The team also sold Notion template guides for books like Atomic Habits and The Psychology of Money for about $5 each through Gumroad.

The service is no longer available at its original URL. A live fetch of gptbook.club in August 2026 returns unrelated King Billy Casino gambling content, and the interactive book search that defined the product is gone.

Readers who used GPT Book Club typically wanted faster takeaways from bestsellers without reading cover to cover. The cached knowledge hub listed abridged guides with chapter summaries, quote collections, and habit or finance trackers built in Notion.

AI Excel Bot turns plain-English instructions into Excel and Google Sheets formulas in seconds. It is built for spreadsheet users who know the outcome they want but do not want to hunt through function syntax to get there.

Unlike general chat assistants, it stays focused on spreadsheet work: generating formulas, explaining nested functions line by line, and writing or decoding VBA. Pro plans add in-spreadsheet access through a Chrome extension for Google Sheets and an Excel add-in, so you rarely need to copy results from a separate tab. The site says formula output runs on a GPT-3 model.

Query Labs operates the service from India. You can work from the web app or install the Chrome extension to stay inside Google Sheets. The formulas page documents support across array, database, date, financial, lookup, logical, math, statistical, text, and other formula families.
