Free.ai for Excel, Word, PowerPoint and Google Sheets

Ask Free.ai to change your spreadsheet, explain a formula, clean a column, draft or rewrite a document, or build slides, without leaving the app you are working in.

Download the Office add-in How to install

Excel

  • Ask in plain words: add a column, write formulas, format a header, sort out totals.
  • Turn a range into a table or a chart.
  • Explain the formula in the selected cell.
  • Clean a column: spacing, capitalisation, dates and typos.

Word

  • Draft a letter, report section or email from a short description.
  • Rewrite the selected text: clearer, shorter or more formal.
  • Add a summary after the selected text.

PowerPoint

  • Describe a presentation and get the slides added to your deck.
  • Title slide, content slides with short bullet points and a closing slide.

Google Sheets and DocsComing soon

  • The same spreadsheet actions in Google Sheets.
  • Draft, rewrite and summarize in Google Docs.

You stay in control

The add-in shows every proposed change as a list and writes nothing until you press Apply. It sends only the selected cells or text with your request, cut to a fixed size, and it refuses formulas that would send your data to a website.

Uses your Free.ai account

Requests use tokens from your Free.ai account, the same as chat on the website, including the free daily allowance. Create a free account

Google Sheets and Google Docs

The Google Workspace add-on is waiting for its Google Workspace Marketplace listing. Once it is listed you will install it from Extensions, Add-ons, Get add-ons, and this page will link to it.

Frequently Asked Questions

It reads the cells you select (or the whole sheet, capped in size), and you ask for what you need: add a calculated column, write formulas, format a header row, turn a range into a table or chart. It also explains the formula in the selected cell and cleans a messy column. Every change is shown as a list first and only happens when you press Apply.

Draft new text from a short description, rewrite the selected text (clearer, shorter, more formal, or however you ask), or add a summary after the selection.

Describe the presentation you need and it adds the slides to your deck: a title slide, content slides with short bullet points, and a closing slide. You can then edit them like any other slide.

A Google Workspace add-on with the same actions for Sheets and Docs is built and waiting for its Google Workspace Marketplace listing. This page will explain how to install it once it is listed.

Until the add-in is listed in Microsoft AppSource, download the manifest file from this page and upload it in Office: in Excel, Word or PowerPoint on the web, open Add-ins, choose More add-ins, then My add-ins and Upload my add-in. The steps for Windows and Mac desktop are on this page.

Press Connect Free.ai account in the add-in and sign in to free.ai in the window that opens. You can also paste an API key from the developer page instead.

The add-in is free to install. Each request uses tokens from your Free.ai account, exactly like chatting on the website, so the free daily allowance works here too and paid plans and token packs give you more.

Only what the request needs: the selected cells or the used range of the active sheet, cut to a fixed size, or the selected text in Word, together with what you typed. It does not upload the file.

No. The add-in shows the proposed changes and nothing is written until you press Apply. In Excel you can undo the cell values it wrote with one click.

The add-in refuses formulas that fetch from or link to the internet, such as WEBSERVICE, IMPORTXML, IMPORTDATA, IMAGE and HYPERLINK, so a suggested change cannot send your cells to a website.

Excel, Word and PowerPoint on the web, Microsoft 365 on Windows and Mac, and Office 2019 or later. Slide generation works best in current versions of PowerPoint; older versions insert the outline as text.

The same self-hosted model that powers Free.ai chat, running on our own GPU servers.
