Technology

The inq platform.

A full-stack handwriting intelligence platform spanning pen hardware, cloud sync, and AI.

Smart pen hardware meets an open software platform.

Platform

Smart pen hardware meets an open software platform.

The inq smart pen captures every stroke with sub-millimeter precision using Bluetooth and micro-dot pattern paper. That handwriting data flows through a layered platform of local SDKs, bi-directional cloud sync, and cloud APIs, giving developers and teams full control over how handwritten data is captured, processed, and used.

Integrate with inq cloud handwriting data to build custom workflows and apps.

Data APIs

Integrate with inq cloud handwriting data to build custom workflows and apps.

Access handwriting data after it syncs to the cloud. Build seamless integrations with event-driven webhooks or real-time Server-Sent Events. Route handwritten notes into CRM, ERP, compliance, and productivity systems automatically.

Event-driven webhook delivery for new handwriting data
Server-Sent Events for real-time streaming to dashboards
Simple REST API for data retrieval and search
Works with no-code platforms and custom backends alike
Build custom apps that connect with inq pens.

Pen Local SDK

Build custom apps that connect with inq pens.

A multi-platform library for handling Bluetooth connection and interacting directly with inq pens. Receive real-time stroke data on any device and build fully custom pen-connected experiences.

Direct Bluetooth pen connection on iOS, Android, macOS, Windows, and Linux
Real-time stroke data streaming from pen to device
Build fully custom pen-connected apps and utilities
No cloud dependency required

Manage handwriting data across devices.

Sync SDK

Manage handwriting data across devices.

Handle stroke data, bi-directional cloud syncing, and arbitrary metadata enrichment. Typically paired with the Pen Local SDK, the Sync SDK enables complex custom apps that operate on local data with full cloud backup.

Real ink. Real paper. Full fidelity.

Hardware

Real ink. Real paper. Full fidelity.

The inq smart pen writes with real ink while capturing every stroke digitally via Bluetooth with sub-millimeter accuracy.

Built-in Bluetooth captures every stroke in real time
Sub-millimeter accuracy for handwriting, sketches, and diagrams
Micro-dot pattern notebooks for precise digital capture
Offline-first: captures locally on-pen, syncs when in range
Enterprise-grade trust.

Compliance

Enterprise-grade trust.

Built for industries where compliance, auditability, and data integrity are non-negotiable.

Cryptographically secure timestamps and tamper-evident records
Full audit trail for every stroke, edit, and access event
Chain-of-custody with automatic metadata capture
Ready for SEC, FINRA, FOIA, and government retention requirements
