Our pick for everyday ChatGPT work: StylerGPT
StylerGPT brings together privacy-first local tools, deep visual customization, interactive prompt refinement and direct PDF/DOCX output. Its conversation tools do not route your chat content through StylerGPT’s servers. For people whose main workspace is ChatGPT, that combination makes it our overall recommendation. Superpower stands out for research and automation, GPT Master for contextual Side Chat and Minimap navigation, and AI Toolbox for organizing work across four AI platforms.
The best choice depends on which of those strengths you will use. Privacy also depends on the action: Superpower generates PDFs locally but has server-backed workspace sync; GPT Master’s AI tools transmit draft/context content; AI Toolbox normally uploads conversations for PDF generation, with a local fallback. StylerGPT generates PDF and DOCX on-device. See StylerGPT plan limits or read the detailed comparisons below.
Keep your favorite tools. Add StylerGPT’s look.
You do not have to replace your current toolkit or buy a StylerGPT license to personalize ChatGPT. Start with StylerGPT Free for palettes and basic appearance customization, or choose Pro for advanced fonts, backgrounds, bubbles and layout. Let Superpower ChatGPT, GPT Master or AI Toolbox provide the tools you prefer. Disable overlapping StylerGPT tools in the Toolbox and avoid applying competing appearance or width settings in both extensions. Power is needed for complete theme presets and Background Roulette.
StylerGPT’s modular controls support this complementary setup, and its code includes styling integration for Superpower. Combining full toolkits can introduce duplicate controls or sidebar conflicts, so each detailed comparison explains which settings to separate. A companion extension still handles data under its own privacy rules: StylerGPT does not make another extension’s uploads local.
