Core Pillars

Everything closed assistants charge for. Sovereign.

VibeTest™ Visual Eyes

AI models generate hallucinated HTML they cannot see. Kanso launches headless Chrome, evaluates WCAG contrast, detects empty voids (>85px), and prevents mobile horizontal overflow.

Universal Handoff 2.0

Switch from Claude to Codex, Cursor, or Gemini without repeating context. Captures git diffs, working tree state, and next steps in a universal snapshot. Apply with one command.

100% Offline Memory

Your preferences, bug solutions, and architectural lessons live in ~/.kanso/memory.json. Zero cloud dossiers, zero data harvesting, zero tracking.

The Community Registry

The Hugging Face of Agent Memory & Visual Rules.

Why let your AI models make the same mistakes twice? With Kanso Hub, install community-verified heuristics and visual compliance packs directly into your offline episodic memory.
