Claude Desktop

Token Saver is a local Claude Desktop extension developed at Marktechpost AI Media Inc. It searches PDFs stored on the user's computer using local hybrid retrieval—BM25 and embedding search—then sends Claude only the passages relevant to a question, with exact page citations, instead of placing the entire document in the context window. The extension is distributed as a one-click .mcpb file and bundles its search engine, requiring no Python, terminal, or configuration files; documents remain on the local machine. It also supports document-folder selection, document listing, disambiguation when multiple files match, and reusing a loaded document for follow-up questions.

An SDK for building AI agents that can operate beyond a standard chatbot. The video describes it as providing filesystem access, tool calling, code writing, and debugging capabilities; AssemblyAI used it to build the Joey support agent with local Markdown documentation, embeddings, agentic file search, and a large CLAUDE.md configuration file.

Claude is a family of large language models and service developed and hosted by Anthropic, an AI safety and research company building reliable, interpretable, and steerable AI systems. Available through Anthropic's web chat products and a commercial API, Claude accepts text prompts and structured inputs or file attachments via the API and returns natural-language and code outputs for tasks such as coding, summarization, document Q&A, and general business and productivity workflows. It is used inside Anthropic products such as Claude Code, by third-party services via Anthropic's API and enterprise agreements, and as an alternative model provider for the model-agnostic Strands Agents framework.

Claude for Siri is an experimental, open-source macOS menu bar app and App Intents model-delegation provider that exposes a signed-in Claude Code account through macOS Spotlight and Siri. It is an independent implementation, not an official Apple or Anthropic integration. A sandboxed provider extension sends text requests over authenticated localhost NDJSON to a Swift bridge in the host app, which invokes the Claude Code CLI in a temporary directory with tools, MCP servers, Chrome integration, and conversation persistence disabled. The resulting text streams into Apple's native response UI; each request starts a fresh conversation. Writing Tools support for selected text is implemented but not verified in the native UI, and the provider does not handle images, attachments, device actions, or Siri access to mail, contacts, messages, or the semantic index.

Claude in Slack is an AI integration that makes Claude available within Slack.
