HEJI AppsSmall apps, carefully made

Each one does one job well, works when the network doesn't, and lets your own AI assistant in through an open door: MCP.

The apps

Waypack

Your trip, packed. Your AI assistant plans it; Waypack turns the plan into a self-contained bundle with offline vector maps that works with no signal at all.

Wee Hours

A newborn log built for 3am. Log a feed, diaper or nap in three seconds by voice, a tap, your watch or your glasses; the voice model runs on the phone.

Voxbrief

Speak an idea, get a clean note. One tap on Apple Watch records it; the iPhone or Mac turns it into structured Markdown with Whisper and Qwen3 running on the device. No account, no server.

A remote workspace for vibe engineering: split panes of real terminals, browsers and a code editor, served from your own machine and reachable from any device. Shells survive refreshes and device switches.

Contempo

Hours that survive an audit. Short-term-rental hosts log work by voice on the phone or watch; Contempo turns it into contemporaneous, risk-checked records for the IRS material-participation tests.

FeedbackKit

In-app feedback that closes the loop: users report with a screenshot, a coding agent fixes it, and the reporter is asked "is it fixed?" in the next build. The tool every HEJI app ships with.

How we build

Works offline first

Trips open without signal; the baby log lives on the phone and syncs when it can. The network is a bonus, not a dependency.

Your assistant, invited

Every app speaks MCP with proper OAuth, so the assistant you already use can read and act on your data, with your permission.

Private by design

Voice is understood on the device. Each app keeps its own data, even where they share an account.

Built to stand alone

The apps share one repository and one backend while they're small, with rules that let any of them move to its own the day it needs to.
