teckel

Teckel provides (i) "teckel AI": an AI chat interface with the most popular LLM families: Gemini, ChatGPT, Perplexity, DeepSeek, and Claude, enabling simultaneous conversation with the multiple models ("CrossListen") and (optionally) inter-model conversation between them ("CrossTalk"); and (ii) "teckel talk": a completely anonymous, secure chat service enabling end-to-end encrypted text communication. Teckel AI supports the most common model variants within each LLM family. Gemini, ChatGPT, and Claude have access to the teckel MCP toolkits, extending the capabilities of the LLMs in a variety of domains. Currently available toolkits include: the teckel ethereum toolkit, the teckel navigation toolkit, and the teckel IPFS toolkit. The app includes a Prompt Library comprising the teckel Prompt Gallery -- a showcase of example prompts curated by teckel; and the User Prompt Library -- where you can conveniently save your own prompts for future re-use. For managing long-running LLM requests, the asynchronous response mode incorporates in-app notifications to inform you when the given job is complete. The app provides IPFS (Interplanetary File System) backend-storage for managing media files (audio, video, txt, etc) for interaction with the LLMs. Access to the LLMs and IPFS is paid for using "teckel credits" available via In App purchase. The teckel talk text-based messaging service utilizes Ethereum addressing for authentication. There is no involvement of cryptocurrency: the Ethereum crytpography is harnessed for authentication, offering security with complete anonymity. There is no limit to the number of Ethereum addresses that can be created (or imported). Teckel talk does not require a phone number or email address, does not record IP addresses of users, and does not utilize cloud infrastructure. Chat sessions are completely ephemeral, no data is stored on the device or on any servers, though chat (and teckel AI) sessions can be archived for offline sharing. All content can be personally moderated and any Ethereum address can be blocked. Messages are encrypted in transit via SSL. Two-way chats are end-to-end encrypted using the Diffie-Hellman algorithm. Optionally, group chats of three or more participants can be end-to-end encrypted using pre-agreed ephemeral passwords (shared between users offline). General public messaging is free. Private group messaging is available through the payment of teckel credits available via In App purchase. Teckel credits can also be used to access teckel APIs aimed at developers. Currently available APIs mirror the teckel MCP toolkit functions. API key management is authenticated via Ethereum addresses within the app. The teckel IPFS toolkit is also available as a verified n8n community node, distributed with n8n Cloud — drop the node onto any workflow to store, retrieve, pin, encrypt and share files on IPFS without depending on AWS, Azure, or Google Cloud. The same encryption layer works identically across the app, the n8n node, the API, and MCP-driven AI agents, so encrypted IPFS content is fully portable between every surface — encrypt in one place, decrypt in another. Two further n8n packages are in verified review: teckel Ethereum (read-only JSON-RPC for mainnet and Sepolia) and teckel Navigation (METARs, TAFs, VFR route calculation, airport search).
