StylerGPT

Provides a theming engine that overlays custom CSS stylesheets onto ChatGPT's DOM, enabling users to switch between pre-built themes (dark mode, light mode, custom palettes) or create custom color schemes. The implementation likely uses CSS variable injection or stylesheet swapping to modify the ChatGPT interface without altering backend functionality, preserving all native ChatGPT capabilities while changing visual presentation.

Implements a tagging and metadata system that wraps ChatGPT conversations, allowing users to assign custom tags, categories, and labels to chats for organizational purposes. The system likely stores metadata in a local database or cloud backend separate from ChatGPT's native conversation storage, then surfaces this metadata in a custom sidebar or search interface to enable filtering and retrieval without modifying ChatGPT's native folder structure.

Implements customizable keyboard shortcuts for common actions (new conversation, search, export, share) to accelerate workflow for power users. The implementation likely registers global or scoped keyboard event listeners and maps them to UI actions or API calls, with a settings panel for customization.

Applies typography and layout improvements to ChatGPT's response rendering, including adjustable font sizes, line heights, code block styling, and markdown rendering enhancements. The implementation likely intercepts ChatGPT's markdown-to-HTML conversion or applies post-processing CSS to improve visual hierarchy, contrast, and readability without modifying the underlying response content or model behavior.

Enables users to export ChatGPT conversations in multiple formats (Markdown, PDF, HTML, JSON) with optional formatting, styling, and metadata preservation. The implementation likely renders the conversation to an intermediate format (HTML or AST), then uses format-specific exporters (markdown serializer, PDF renderer, JSON serializer) to generate downloadable files while preserving conversation structure, timestamps, and styling.

Implements a client-side or server-side full-text search index across all user conversations, enabling fast keyword search, semantic search, or filter-based retrieval without relying on ChatGPT's native search. The implementation likely builds an inverted index of conversation content (titles, responses, metadata) and surfaces results through a custom search UI with filtering by date, tags, or model used.

Enables users to generate shareable links to conversations with optional access controls (read-only, password-protected, expiring links) and optional redaction of sensitive information. The implementation likely stores conversation snapshots in a database, generates unique URLs, and applies access control middleware to enforce permissions without exposing the user's ChatGPT account.

Automatically generates summaries and extracts key insights from conversations using either ChatGPT's API or a separate summarization model, displaying summaries in the sidebar or conversation header for quick reference. The implementation likely calls ChatGPT's API with a summarization prompt or uses a dedicated summarization model to generate concise summaries without user intervention.

Enables side-by-side comparison of two or more conversations, highlighting differences in responses, approaches, or outcomes for the same or similar prompts. The implementation likely renders conversations in a split-view layout with optional diff highlighting (showing added/removed text) and metadata comparison (model, tokens, response time).

Allows users to create and save reusable prompt templates with variable placeholders, enabling quick insertion of common prompts or prompt patterns into new conversations. The implementation likely stores templates in a database or local storage, provides a template picker UI, and performs variable substitution when a template is selected.

Tracks and displays statistics about ChatGPT usage patterns, including conversation frequency, token usage, model distribution, response times, and cost estimates. The implementation likely aggregates metadata from conversations (timestamps, token counts, model used) and renders dashboards or charts showing usage trends over time.
