Customize ChatGPT's width, font size, sidebar spacing, padding and layout with simple live controls. ChatTuner gives you live control over ChatGPT's layout, density, and typography. Click the toolbar icon to open a compact appearance panel directly over ChatGPT. The panel stays open while you use the page, so every adjustment is visible immediately. Tune the interface to suit the way you read: - Change sidebar width, item and menu vertical padding, font sizes, and section spacing. - Set a conversation max width from 600 px to 1600 px and keep the composer aligned with it. - Adjust body font size, line height, paragraph spacing, and spacing between turns. - Keep the composer aligned with the conversation width. - Start from Default, Compact, or Dense presets and fine-tune individual values. - Temporarily disable all changes without losing your saved settings. Settings are saved through Chrome's sync storage. ChatTuner has no account, analytics, advertising, external service, or cloud backend. It does not read, retain, or transmit conversation text. ChatTuner is an independent product by Latent Builds. It is not affiliated with or endorsed by OpenAI.
