Gemini: Your always-on AI assistant in Docs

We are introducing the ability to set custom, persistent instructions for Gemini in Google Docs. These instructions ensure that Gemini adapts to your style, tone, and formatting preferences without needing to repeat them in every conversation, ultimately saving you time and ensuring consistency.

Users can add instructions and rules using Gemini in the side panel of Docs such as “Always respond in bullet points,” “When summarizing Docs, always include a 3 bullet points at the top.”” or “Use a concise and professional tone for all my documents.”

Note that users are currently limited to 1000 active instructions.

Google Help: Customize Gemini in Workspace’s responses with your instructions

As of May 2026, Gemini in Google Docs has evolved from a simple drafting tool into a comprehensive, “always-on” collaborator. Following the Google Cloud Next ’26 updates, its role focuses heavily on agentic automation—meaning it doesn’t just write text, but manages entire document workflows and file generation.

Here’s a breakdown of its current capabilities:

1. Direct File Generation & Transformation

The most significant shift in 2026 is that Gemini is now a file generator, not just a text generator.

Instant Export: You can prompt Gemini to “Turn these notes into a structured PDF” or “Convert this brainstorm into a Google Slide deck.” It creates the file directly without requiring you to copy-paste.
Format Conversion: It can transform mixed inputs—like a photo of a whiteboard, a CSV of raw data, and a few handwritten notes—into a polished, shareable business report or a LaTeX document.

2. Contextual “Sources” & Smart Canvas

Gemini now acts as a bridge between all your Workspace data.

The @ Menu for Context: You can type @ to tag specific files in your Drive or emails in your Gmail as sources. For example: “Update the project timeline in this doc based on @LatestMeetingNotes and @StatusUpdateEmail.”
Research & Synthesis: Within the side panel, Gemini can scan your entire Drive to answer questions like, “What are the recurring themes across our last five Q3 strategy docs?” and then draft a summary directly into your current page.

3. Personal & Professional Intelligence

Match Writing Style: Using a feature called “Personal Intelligence,” you can ask Gemini to analyze a previous document you wrote and then apply that specific voice, tone, and formatting to a new draft.
Fill with Gemini: Inside tables, Gemini can now auto-populate data. If you have a column for “Company Name” and another for “Latest News,” Gemini can crawl the web and fill the entire table for you.

4. Enterprise Agentic Features

For those using the Gemini Enterprise Agent Platform (the successor to Vertex AI), Docs integration has become even more advanced:

Multi-Step Agents: You can set up agents that “watch” a document. When you add a new client name to a list, the agent can automatically generate a customized welcome letter and save it to a specific folder.
Model Switching: Enterprise users can toggle between different models (like Gemini 3 Flash for speed or Pro for deep reasoning) directly from the Docs sidebar.
