One graph. Every relationship.
Calendar, tasks, notes, contacts, projects, and code stop being separate apps and start being one typed graph. You search it. Your agent traverses it. Nobody starts blind.
Reality Grid
Events, tasks, and available time in one view. Drag tasks from your inbox into time slots. See whether your day is realistic or fantasy.
AI Chat
The chat knows your calendar, tasks, relationships, and preferences. Ask it to plan your day, break down a project, schedule a meeting, or think through a decision. It responds with real actions.

Task Intelligence
Dump your to-do list into chat. The AI breaks it into subtasks, estimates effort, groups by project, and finds time slots in your calendar. Turn "clean the house" into a scheduled plan.
Silent Learning
Siftable builds an understanding of your life: 50+ attributes across preferences, work style, relationships, goals, and health patterns. It learns from natural conversation, not onboarding forms.
"What time do I usually wake up?" — Your assistant already knows, because you mentioned it in passing three weeks ago.
Life Matrix — 50+ learned attributes
Personal CRM
Add people through conversation: "I met Sarah at the conference, she's a designer at Figma." The AI extracts details, remembers context, and surfaces connections when relevant.
Notes, Concepts & Datasets
Meeting notes, daily logs, concepts, reference material, and structured datasets with faceted search. Import PDFs, spreadsheets, and documents. Everything is searchable, connected, and queryable by agents via MCP or CLI.
Codebase Intelligence
Register your repositories for semantic code search, expertise tracking, and code memory. Find functions by description, discover who knows what, and store architectural decisions. Accessible from your IDE via MCP or from your terminal via CLI.
