Free private journaling app

Inner Companion

A private journaling PWA — complete and installable, verified from the founder's archive in October 2026: offline-first, with its journal stored on the user's own device.

I
CONCEPT VISUAL —
A complete, installable, offline-first journaling PWA — private by architecture, not by promise.

The goal

Private journaling that stays on the user's own device — offline-first, with its journal stored in IndexedDB behind a service worker.

What it does — the task

  • Complete, installable journaling PWA, verified from the founder's archive in October 2026
  • Offline-first: the journal is stored on the user's own device (IndexedDB + service worker)
  • It has no repository and no hosting yet — which also makes it the shortest path in this portfolio to a shipped product: host the PWA, no app-store gate

Why it exists

Inner Companion exists so a private journal can stay genuinely private — on the user's own device, working offline, with nothing sent anywhere.

Status: Built — unhosted; a complete build exists and has not been released.
