DapperGPT

Provides a single chat interface that abstracts away provider-specific API differences, allowing users to switch between OpenAI GPT, Anthropic Claude, Google Gemini, Mistral, Grok, and Llama by selecting from a dropdown and providing their own API keys. The interface normalizes request/response handling across providers with different tokenization, rate limits, and response formats, eliminating the need to maintain separate tabs or applications for each model.

Stores all chat conversations server-side (security model unspecified) and indexes them for Spotlight-like full-text search, allowing users to retrieve past interactions by keyword without scrolling through history. The search appears to index both user prompts and AI responses, enabling discovery of relevant conversations across sessions. Conversations can be organized into folders and pinned for quick access.

Accepts file uploads (types and size limits unspecified) and image uploads, injecting their content or visual information into the chat context before sending requests to the selected LLM provider. The system appears to handle file parsing and image encoding transparently, allowing users to reference documents, code, or images in prompts without manual copy-paste. Implementation details for file type support and preprocessing are undocumented.

Allows users to create, save, and reuse custom prompts as templates that can be applied to new conversations. Prompts appear to be stored per-user and can be selected from a dropdown or menu before initiating a chat. This enables rapid iteration on prompt engineering without re-typing complex instructions for recurring tasks.

A Chrome extension (currently marked 'available soon' — not yet production-ready) that brings DapperGPT's chat interface to any website, allowing users to leverage AI capabilities without leaving their current browser context. The specific integration pattern (sidebar, overlay, context menu) is undocumented, as is the mechanism for capturing page context (selected text, DOM content, page metadata). Extension will likely use Chrome's extension APIs for content script injection and message passing.

Supports agent-based AI interactions where the LLM can invoke external tools and services through a Model Context Protocol (MCP) integration or custom toolchain. The system appears to enable 'human-like responses' through agentic loops, though specific tool types, MCP implementation details, and available tools are undocumented. Web browsing and code execution are mentioned as available tools but their implementation is not detailed.

Allows users to pin frequently-accessed conversations to the top of their conversation list and organize conversations into folders for hierarchical grouping. This provides lightweight project/topic-based organization without requiring tagging or automatic categorization. Pinned conversations appear in a dedicated section for quick access.

Offers a freemium tier that allows users to test the DapperGPT interface and features without cost, requiring only a free account creation. Full functionality (multi-provider access, conversation storage, search) is unlocked by providing their own API keys from supported LLM providers. This model eliminates platform-imposed usage limits while maintaining transparent, provider-direct billing — users pay OpenAI, Anthropic, etc. directly rather than through DapperGPT.

Provides a modern chat UI with support for multi-turn conversations, message editing/deletion, conversation forking (implied by conversation management features), and visual formatting of responses. The interface normalizes chat interactions across different LLM providers, handling provider-specific response formatting and streaming. Conversations are persisted server-side and can be resumed across sessions.
