Google Docs’ Gemini now remembers your writing preferences

Anyone who regularly uses AI writing tools knows the pain. You spend half your time reminding the AI about your preferred tone, format, and style quirks. Every single prompt becomes a mini-essay of instructions before you even get to the actual request.

Google is finally addressing this workflow friction. The company announced that Gemini in Google Docs now supports persistent custom instructions, letting users set their preferences once and have them apply automatically to every interaction.

The feature works through Gemini’s side panel in Google Docs. Users can define rules that the AI assistant will remember and apply consistently across all documents. This means no more typing the same formatting requests or style guidelines with every prompt.

Google provided several practical examples of how the feature works:

• “Always respond in bullet points”
• “When summarizing Docs, always include 3 bullet points at the top”
• “Use a concise and professional tone for all my documents”

This addresses a major pain point for professionals who rely on AI writing assistance. Marketing teams can set brand voice guidelines once. Technical writers can establish formatting standards. Content creators can define their preferred structure and tone without constant repetition.

The timing makes sense given the broader push toward more personalized AI experiences. As AI tools become workplace staples, users expect them to adapt to individual preferences rather than requiring constant manual guidance. This update puts Google Docs in line with that expectation.

Google is allowing up to 1,000 active instructions per user, which should cover even the most detailed style requirements. The company notably decided against admin controls for this feature, giving individual users full autonomy over their Gemini customization.

The rollout began on May 4 for both Rapid and Scheduled Release domains. Access requires a Gemini-enabled Workspace plan, which includes Business tiers (Starter, Standard, Plus), Enterprise tiers (Starter, Standard, Plus), Education Plus, and consumer plans (Google AI Plus, Pro, Ultra).

This update represents Google’s broader strategy of making AI tools more seamlessly integrated into daily workflows. Rather than treating AI as a separate tool that requires specific interaction patterns, features like persistent instructions help it function more like a customizable writing partner that understands your preferences.
