Graylin gives you a personal AI pod β€” your own AI workspace that manages tasks, automates workflows, handles contacts, and works across channels. It's not just a chatbot. It's a capable assistant with its own tools, memory, and personality. CHAT WITH YOUR AI Have natural conversations with your AI assistant. Graylin streams responses in real time, remembers context across sessions, and supports media attachments. Organize conversations into projects for easy reference. MANAGE TASKS A full task board with drag-and-drop Kanban columns: backlog, todo, in progress, blocked, done, and more. Your AI can create and update tasks for you, or you can manage them yourself. AUTOMATE WORKFLOWS Build multi-step automations with triggers and actions. Graylin's workflow builder lets you create powerful automations β€” from scheduled tasks to event-driven pipelines β€” with AI-assisted step creation. SMART TOOLS & SKILLS Your AI pod comes with built-in tools for web search, email, shell commands, and more. Browse and enable skills to extend what your assistant can do. CONTACT MANAGEMENT Import and organize your contacts with groups and lists. Graylin syncs with your device contacts and helps you keep everything organized.

About

Nabuchodonosor

Features
Read full description

Your model. Your rules. Nabuchodonosor is a private chat interface that connects to the AI engine you choose: Ollama on your local network or Tailscale, or an OpenAI-compatible API available over HTTPS. FREE AT THE APP LAYER The app sends your requests to the model without rewriting, moderating, or adding refusals. Final behavior remains that of the model and provider you choose. EPHEMERAL BY DEFAULT Messages stay in memory only. No history is written to your iPhone. Background clearing is enabled by default. Recent context is off by default; if enabled, it remains limited to this session and 12,000 characters. BRING YOUR OWN MODEL Enter any model name, use an Ollama token provided by the Mac app, or add a key for your compatible server. Secrets are protected in this iPhone’s Keychain and are not synchronized. VERIFIABLE PRIVACY No Nabuchodonosor account. No analytics, telemetry, uploaded crash reports, or cloud sync. The network session uses no caches or cookies. Important: every request is sent to the engine you configure. If you choose a remote service, its retention practices and restrictions depend on that provider, not Nabuchodonosor.
