A private memory journal

Each memory a tile. Together, a portrait of you.

A quiet place for the things worth remembering. Soft by design, stored only in your iCloud, opened with your face.

Tessera is a small app for a long practice. Write freely, file later. Build a library of moments — exact-dated or just the feeling of a year — and let them gather quietly into the shape of a life. No scoring. No streaks. No cheering from the margins. Only the pages you choose to keep, and the slow, honest portrait they become.

the chapters

What it does, quietly.

Four ideas, arranged like a table of contents. Nothing clever. Nothing loud.

I. the blank page

Write freely.
File later.

A single tap opens a blank page. No era, no tags, no mood required — just a cursor, waiting. When you're done, the memory drops into your inbox until you decide where it belongs.

The first tile.

II. eras

Chapters of a life.

Eras are the autobiographical chapters only you can name. "Childhood" can hold "Pittsburgh years," which can hold "Before my parents divorced." Each era keeps its own count and a quiet mood distribution at a glance.

Therapy is era-oriented. So is the app.

eras

▾ Childhood 142
▾ Pittsburgh years 88
▾ Before my parents divorced 31
▾ College 67
▾ First marriage 94
▾ Now 21

III. tags, mood, flags

The quiet apparatus.

Tags are nested and cross-cutting — family/mom/advice is three linked threads. Mood is a single soft five-point scale. Two flags, no more: core for the ones that anchor you, in progress for the ones you want to return to.

Four ways to remember when.

Not every memory has a Wednesday attached. Choose exact, approximate, a whole era, or no date at all — your timeline respects the difference.

exact March 14, 2024 pinned to the day
approximate circa 2003 grouped by year
era-only sometime in childhood placed by chapter
undated — still remembered

the portrait tab

The shape of what you've kept.

Soft, quiet visualizations of the collection you are building. More like an infographic in a literary magazine than a dashboard.

When you open Portrait after three months of writing, the feeling is not "progress." The feeling is: huh. there's a shape here.

a look inside

The app, as it is.

Today on the Mac, and six more pages in your pocket. Soft on the eyes by default, comfortable in the dark when the hour calls for it.
