Hartchain AI Lab
Deputy helps your team work with project files on Windows and macOS, with clear control over what stays private. Ledger reads your books locally and gives you a clear view of business health. Sentinel starts a secure HTTPS server when you need to move data, then shuts down cleanly when you are done, including on smaller Linux and IoT devices. When you are ready to roll out, we can help with support and training.
Trust
Deputy and Ledger work with local files and your own API keys. Sentinel opens a short-lived transfer session, then wipes temporary certificates and staging when you stop. Architecture is built for private deployment: cloud, private VPC, or on-premises when data is sensitive.
Per-seat licensing for Deputy and Ledger. Per-device licensing for Sentinel, with pilot packs available. Volume and enterprise terms when you are ready to grow.

Deputy on Windows and macOS. Ledger on Windows, macOS, and Linux. Sentinel on Linux, Windows, macOS, and constrained Linux IoT. License per seat or per device. Volume and enterprise terms available.
Desktop · Windows & macOS
Per-seat licensing
Workspace-aware AI assistant for your project folder: chat panel, file read/write and search, answers grounded in the files you choose, multi-provider models, tray access, hotkeys, and audit logging. You keep control of what leaves the machine. No screen watching.
Finance · Windows, macOS & Linux
Per-seat licensing · Pilot program
Private business health over your local books. Index PDFs, CSV, and spreadsheets on your machine, score against industry benchmarks, estimate value, and surface dollar-ranked growth opportunities, with source-backed Q&A and scenario forecasting. Your books stay with you.
Data transfer · Linux, Windows, macOS, IoT
Per-device licensing · Pilot packs available
On-demand secure HTTPS server for short-lived data exchange. Start a TLS listener with a one-time session token, upload or download files with put and get, then stop on demand or after TTL and idle timeouts. Ephemeral certificates and auto-created staging are wiped when the session ends. Small CLI for desktops, servers, bare-metal Linux, and resource-constrained IoT devices.
Support & training
Licenses get you the software. Support and training get your team using it confidently: install and licensing help, configuration, user onboarding, and optional retainers for production use.
Priority email support for Deputy, Ledger, and Sentinel: install issues, licensing, configuration, updates, and integration questions. Available per incident or on a monthly retainer for teams running at scale.
Live sessions tailored to your environment: admin setup, Deputy user workflows, Ledger finance workflows, Sentinel serve/put/get operations, and privacy controls. Delivered remotely or on-site for teams that want a structured rollout.
Approach
Products ship on a clear install-and-license path: scoped pilots, deployment, handoff, and optional support or training when you need it.
Choose Deputy, Ledger, or Sentinel. Define seats or devices, OS targets, deployment environment, and success criteria for the pilot.
Run Deputy, Ledger, or Sentinel on a small set of users or devices to validate fit, typically 4-8 weeks.
Roll out licenses and packaged installs across laptops, servers, or IoT hosts as needed.
Documentation, admin guides, and optional support or training packages so your team can operate independently or with Hartchain on retainer.
