Core Product Promise

Capture everything. Organize automatically. Think with your own AI.

Frictionless Capture

Users drop thoughts into the system without deciding where they belong. The interface removes the cognitive load of categorization, crucial for ADHD-friendly design.

Automated Organization

SL8 progressively connects related information, surfaces context, and automates mundane tasks in the background without rigid schemas.

Personal Intelligence

Your AI contextualizes your unique knowledge base. It is a thinking partner that acts on your behalf across connected applications safely.

The Offline-First Principle

Capture never waits. Core functionality relies on local IndexedDB storage. Network drops route operations to a robust pending queue. The canvas remains fluid and editable offline. Cloud sync resumes idempotently when connectivity returns, utilizing CRDTs to prevent destructive conflicts.

Decoupled AI & Privacy

SL8 separates the persistent knowledge layer from the LLM provider. Bring your own API key or use supported OAuth integrations. The system maintains its own strict memory typology (Raw vs. Derived), ensuring AI hallucinations never silently overwrite your ground truth.

Modular Connector API

An n8n-inspired background engine integrates Teams, Slack, Notion, and Jira. Actions undergo strict permission controls inside the Orchestration Engine. Consequential mutations require user approval, while background webhooks continuously ingest relevant context seamlessly.
