Google Antigravity release notes: 2.16.0 reads Office attachments

Google Antigravity 2.16.0 lets you attach Word, Excel, and PowerPoint files directly to a prompt. Gemini models read the documents natively instead of falling back to opening the stored file. Dated September 22, 2026, the update applies to the Antigravity app, Google's workspace for AI agents.

Google Antigravity release notes: Office files directly in prompts

Drag a document into the message box to attach it. Support covers Microsoft Word, Excel, and PowerPoint; the release note explicitly says Gemini models read them natively. It does not specify file size limits or equivalent support for other models.

Google rolls out new versions gradually. Version 2.16.0 may take a few days to reach all users.

Short example: use the new Antigravity feature

Human step: Drag a Word file containing a project proposal into the message box in Antigravity 2.16.0. Use a Gemini model for the document reading described in the release note. Then send this suggested prompt:

Source for file handling: Google Antigravity 2.16.0: drag Office files into the message box.

Read the attached project proposal. List deliverables and dates with references to the document headings. Flag missing dates and conflicting information without filling in the gaps yourself.

Check the result against the document:

• Each deliverable should be traceable to the named heading.
• Dates should be accurate, with missing or conflicting information clearly marked.
