✦ Features
Everything you need
A complete annotation system designed for professional frontends.
Framework Agnostic
First-class support for Angular, React, Vue, and jQuery. One core, four wrappers, zero lock-in.
RSA License Protection
Domain-locked Pro licenses signed with RSA-SHA256. Embed the public key in your bundle for offline verification.
Zero-Config Setup
Add ann-cell-key to any element and you're done. No build step, no extra tooling required.
Permission System
Fine-grained per-cell, per-user, and per-role permissions. Built-in edit, view, and delete controls.
Simple Framework Integration
One package per framework. Add a single provider or directive and annotations just work — no boilerplate, no wiring, no extra config.
100% Offline Ready
No internet required after setup. RSA license verification runs entirely in the browser via Web Crypto API — no server calls, no latency, no outage risk.
AI Agent — Scope & Build
Confirm project scope visually, then let an AI Agent generate your database schema and backend API from annotated fields. From UI to production data layer in minutes.
Onboarding & Guided Tours
