A personal continuity OS

Your life, kept in your own words.

Presencia remembers the way a good friend does: what you actually said, when you said it, and where each word came from. Ask it something, and it answers from your own record, with every line cited.

Decision Matrix is Presencia Decisions on its own, in your browser.

What it is

Four experiences at the center. One record underneath.

Your notes, conversations, decisions and listening live in one private record. Each keeps its original words, its own dates and its origin, so a moment stays recognizable wherever it appears, and a later reading never rewrites what you first wrote.

Desk + Presencia Notes

Where a thought arrives, becomes work, and can be found again.

Write with honest dates: a year stays a year, and an unknown date stays unknown. Every save is a new revision, so nothing you wrote before is overwritten. Reflect on a note with Entity when you want a second look.

Detail of the source inspector: the note “Afterlight · listening moment”, marked Your words and Synthetic demo, with when it happened, when it became known and when it was recorded.

Entity

Ask something you didn't prepare.

Entity answers only from the sources you chose. Each line points to the exact passage it came from, it names what it couldn't read, and when nothing matches, it says so. It shows how each answer was made, and it never pretends to be human.

Working in the private build

Detail of an Entity answer at iPhone size: two matching passages quoted as written, without a language model, each shown with its source and date; the second is marked as a generated summary.
Synthetic demo data Entity: an answer arranged from chosen sources, with its limits named.

Presencia Decisions

A simple place to bring a difficult question.

Name what you know, what's uncertain and what's still needed. Compare options against what matters to you, and see which blanks could still change the lead. Choose, park or decline, then return with Echo once you've lived it.

Detail of the decision field at iPhone size: four options as ranges on a zero-to-ten scale, one excluded by “No new debt”, the chosen one marked “Your choice”, and a plain sentence saying the leader isn't separable yet.
Synthetic demo data Presencia Decisions: each option drawn as the range its blanks still allow.

Listening Room

Music met through a particular life, at a particular moment.

Atlas Live follows the recording that's actually playing. The lyrics, the song's own notes and your words at each line stay separate, and your meaning can change without rewriting the first listen.

Working in the private build

Detail of the Listening Room lyrics panel: the current line “Keep the porch light on”, the tabs for meaning as it unfolds, and the listener's own note at this line.

Presencia's Home on a Mac: the time spine of moments with one note selected, and the source inspector open beside it. The note, “Afterlight · listening moment”, is marked Your words and Synthetic demo, with when it happened, when it became known, when it was recorded, its two revisions and the correction that was recorded.Entity's first conversation on a Mac: the chosen sources on the left, each with its readiness, and on the right an answer made of quoted passages with source chips, a Limits box noting that one passage is AI-generated and that some pages couldn't be read, and buttons to confirm or correct.A Presencia decision on a Mac titled “Which launch can I sustain this year?”: four options drawn as ranges on a zero-to-ten scale, one struck through as excluded by a non-negotiable, the chosen option marked in gold, and a sentence saying the leader isn't separable yet.The Listening Room on a Mac following the original synthetic track “Afterlight” at 0:33: signal lanes marked as having no live source, lanes for lyrics, sections, repeats and loudness below, the current lyric line on the right, and the listener's own notes at that line.

The continuity journey

  1. Bring context
  2. Encounter a moment
  3. Ask
  4. Inspect
  5. Choose
  6. Make
  7. Use
  8. Reflect
  9. Optionally share

No step silently grants permission for the next. Saving isn't adopting, choosing isn't acting, and inviting someone isn't opening your whole record.

How it treats your words

Exact about what you said, when you said it, and where it came from.

A memory worth trusting has to show its work.

  1. Every word carries its origin

    Your words, a kept Human–AI conversation, machine text, generated text, or origin unknown: each is shown as a word and a shape, never by color alone. Generated text can never be relabeled as yours.

    • Your words
    • Kept Human–AI
    • Machine text
    • Generated
    • Origin unknown
    The inspector's origin labels for one note: Your words, and Synthetic demo.
  2. Every moment keeps its own dates

    When something happened, when you knew it, and when it was recorded are kept apart. Ask “as I knew it then,” and anything you learned later stays out of the answer.

    The inspector's dates for one note: when it happened, with its precision and basis, when it became known, and when it was recorded.
  3. Answers cite your own record

    Each line of an answer opens the exact passage behind it. Confirm it or correct it: a correction becomes a new revision, and the original stays in the history.

    The inspector's revision list: the current revision and an earlier one, with a button to compare them.
  4. Nothing leaves without your consent

    Today your record lives on a private node on your own machine. Sending anything to a language model, or to another person, is a separate choice you make. Remove something, and its words leave search, sealed snapshots and the answers that quoted it.

    The app's footer note: Personal node on this Mac. No music provider or sensor is connected; Entity's model is chosen in Settings.
Presencia's Home on a Mac: the time spine of moments with one note selected, and the source inspector open beside it. The note, “Afterlight · listening moment”, is marked Your words and Synthetic demo, with when it happened, when it became known, when it was recorded, its two revisions and the correction that was recorded.

Real screens

From the private build, as it runs today.

Captured from the working app on a Mac and at iPhone size in a browser. Every record on these screens is synthetic demo data: invented to demonstrate Presencia, not anyone's real history.

At iPhone size

Composed for the phone, not squeezed.

The same app in a browser at iPhone dimensions. It hasn't run on a physical iPhone yet, and the native apps are still to come.

Presencia's Home at iPhone size: a synthetic-data notice, the title “The longer story”, and the time spine of moments with the years 2024 to 2026 along a glowing arc.
The Listening Room at iPhone size: the track “Afterlight” by the Presencia Demo Ensemble, marked synthetic and rights-cleared, the playback time 0:33, and the lanes that follow the listen.

Status, honestly

What exists today, and what is still coming.

Presencia measures progress in evidence, not announcements. A capability moves up this ladder only when there's a receipt for it.
