LightPDF vs AI Excel Bot

LightPDF lets you upload PDFs, Word files, Excel spreadsheets, PowerPoint decks, and scanned documents, then ask questions and get cited answers back. The ChatPDF feature runs on GPT-4, supports multi-document chats, OCR for scanned files, and follow-up questions. You can upload a file up to 100 pages on the free web tier before upgrading.

Unlike standalone ChatPDF clones, LightPDF bundles document chat into a wider PDF toolkit with conversion, editing, e-signatures, and a dozen other AI tools like mind map creation, PDF translation, and presentation generation. One premium subscription covers Windows, Mac, Android, iOS, and the web app, with AI credits allocated monthly or as a one-time pool on the perpetual plan.

Researchers, students, and office workers use LightPDF to summarize contracts, extract tables from financial reports, and pull outlines from long readings. Business teams can also use it for document Q&A on proposals and compliance files. The company behind LightPDF has operated since 2015 and holds ISO/IEC 27001, ISO/IEC 27701, and GDPR certifications.

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.
