ChatThread vs Gizmo

ChatThread is a workflow-first AI chat. Choose a workflow to guide the conversation, then ask naturally for more consistent results—writing, summaries, translation, and more. Explore the Workflow Store to install community-made flows in a tap. Build and manage workflows on desktop, then run them instantly on mobile. Upload files (PDFs, docs, images, spreadsheets) to extract key points and get structured outputs. Start in seconds: tap “Start New Conversation” and pick a flow. Support: chatmagic@163.com

Gizmo is a private AI assistant that runs entirely on your iPhone. Unlike cloud chatbots, Gizmo's language model lives on your device. Your conversations stay with you — they are not uploaded to a server. That means it is fast, works offline, and is private by design. WHAT GIZMO CAN DO • Chat naturally — ask questions, brainstorm, summarize, write, and more. • Talk to it — built-in voice input with a "Hey Gizmo" wake word. • Manage your day — view and create calendar events just by asking. • Find places nearby — get local results and directions when you need them. • Search the web — pull in fresh information for the questions that need it. PRIVATE BY DESIGN The AI model runs locally using your iPhone's GPU. Core chat needs no internet at all. Optional features like local search and web lookup only send a request when you explicitly ask for them. If you choose to report a problem with a response, that conversation is shared with us so we can fix it — nothing is sent otherwise. FIRST LAUNCH Gizmo downloads its on-device model once on first launch (about 2.3 GB) — please use Wi-Fi. After that, the assistant is ready whenever you are, online or off. No account. No sign-up. No tracking.
