Idea

A basin for what you notice.

In the Pensieve, Dumbledore draws silver threads from his temple — not to forget them, but to finally be able to look at them. This is the same idea, only for your everyday life.

Pensive is a place for notes, half-thoughts, names, promises, and loose ends. Whatever you drop in becomes entities, connections, questions, collections. A small agent at the heart of the app thinks along in the background — never loud, never pushy.

It runs on your machine. No account, no cloud, no foreign model indexing your memories. Just you and a database that remembers with you.

II
A turn

What happens when you drop something in.

Saw Marco today. He's still stuck on the payment migration. His daughter starts school tomorrow.
a. Entities
Marco payment migration daughter
b. Thought
dated, tagged, placed in the basin — where it can float up again next week or next year.
c. Later
Did the migration ship? Is she settled in school? — quietly, on a Sunday evening.

The agent doesn't answer. It notices.

III
Concepts

Six materials, one basin.

I core

Thoughts

Free, short notes — slips of paper falling into a basin. Timestamp, context, nothing more.

II core

Entities

People, places, projects, things. Aliases are first-class: Marco = m. = Mr. S.

III fabric

Graph

Everything connects to everything. A linker draws edges on a schedule; a small LLM pass resolves ambiguous cases — quietly, in the background.

IV pulse

Heartbeat

A rhythm the agent breathes on. Sleeps when there's nothing to do. Speaks only when it has something to say.

V time

Crons

Recurring small jobs. Every Sunday evening, leaf through the week. That's programming enough.

VI presence

Agent

One nameless background presence. Wakes on the heartbeat, follows the crons, writes back into the same basin you do.

IV
Local

Your database is a file.

You can open it. Read it. Grep it. Back it up on a thumb drive. Delete it. It lives on your disk, not on someone's server.

No account. No sync. No training data. No cloud reaching in.

Pensive is yours.

Manifesto
Software for your own memory shouldn't get smarter. It should get quieter. It should know how to wait.
