Gemini Polish & Graph Viewer

Customizable reading experience for Google Gemini: typography, colour schemes and a split-view Mermaid renderer.

Gemini Polish turns Google Gemini into a reading surface you actually want to spend time in - and keeps the diagram viewer you already know. STYLE AND COLOUR ARE TWO CONTROLS THAT DO NOT OVERLAP Style decides how much of Gemini's layout gets replaced: Native Gemini (changes nothing), Comfortable (17px, 1.7 line height, real paragraph spacing, a readable 860px column), Focus (18px/1.9/700px, disclaimer hidden, action buttons revealed on hover). Colour decides what it looks like - six schemes, each shipping a matched light and dark palette of eight colours: Native Gemini (a true pass-through that emits no colour rules at all, so Google's own palette shows through), Solarized, Nord, Gruvbox, Amber (the only scheme that keeps Gemini's white ground and warms just the accent), and Sepia. SPLIT-VIEW MERMAID RENDERER Flowcharts, sequence diagrams, mindmaps, ER, class and state diagrams and Gantt charts render next to their source. Pan, zoom, auto-fit, side-by-side or stacked, fullscreen, export SVG, or copy as a 2x PNG. A COPY BUTTON THAT DOES NOT HANG THE TAB Gemini's own copy can lock the page on long answers. This adds an MD button beside it that serialises the answer itself - headings, nested lists, blockquotes, tables and fenced code blocks with their language label - in a single pass. WHEN YOU WANT THE KNOBS Advanced opens 21 individual switches grouped by what they act on, six sliders, and a Custom CSS box. DETAILS THAT TOOK THE WORK Every palette we author clears WCAG AA contrast for text, links and inline code - against the surface colour, not just the background. Settings are written locally first and mirrored to your Google account, so a throttled or offline sync never costs you a change. Changes apply as you make them, with no reload. Available in 7 languages. PRIVACY No analytics, no tracking, no remote code, no network requests of its own. Runs only on gemini.google.com. Gemini Polish is an independent project.
