Second Brain Link vs Eddie

Second Brain Link turns the data you already own into a private, AI-queryable "digital twin" that lives entirely on your device. Your LinkedIn, Facebook, Instagram, and Google exports are unpacked, de-duplicated, and linked into one knowledge graph — right on your phone. Nothing is uploaded. There's no account, no tracking, and no cloud. WHAT YOU CAN DO • Build your brain from the data exports you request from each platform • Explore an interactive graph of the people, companies, and topics in your life • Talk to your twin — ask questions and get answers grounded in your own notes • Keep everything 100% on-device and private by design WHY IT MATTERS Your most valuable context — who you know, what you've done, what you care about — is trapped in export archives nobody ever opens. Second Brain Link hands it back to you, working. Your data already exists. It's already yours. It's time it started working for you.

Meet Eddie, a private AI assistant for iPhone and iPad. Chat, translate text, understand images, and explore your own documents using AI models that run directly on your device. Your prompts and content are not sent to a cloud AI service. PRIVATE CHAT Ask questions, develop ideas, write, summarize, and save useful conversations, all powered by your selected local model. YOUR OWN KNOWLEDGE Create personal knowledge bases from notes, PDFs, text files, Markdown, JSON, CSV, XML, YAML, and webpages. Build a local search index, connect a knowledge base to a chat, and ask questions using the information you added. PHOTO UNDERSTANDING Choose a compatible vision model, add a photo, and ask Eddie to describe, explain, or examine its contents. TEXT & PHOTO TRANSLATION Type or paste text, or select photos containing text. Translate the extracted text using your selected local model and play the translated result aloud. CHOOSE YOUR MODEL Explore models compatible with your device and compare their download size, capabilities, and device requirements. Download only the models you want and remove them whenever you need to free storage. LOCAL BY DESIGN • AI inference runs on your device • No account is required • Chats and workspace content are stored locally • No advertising or tracking • Downloaded models can be removed at any time • Export and restore your local workspace • No cloud AI provider receives your conversations After the required models have been downloaded, chat, translation, image processing, and knowledge search can operate without an internet connection. Internet access is required to download models and when you explicitly import a webpage or perform web search. Model availability, performance, and supported capabilities depend on your device, selected model, language, available memory, and storage.
