Your mind
leaves fingerprints
when it writes.

Hyperquery reads your journal entries—fully offline, fully private—and surfaces the emotional and cognitive patterns you cannot see yourself.

How it works

Pattern
recognition from
your own voice.

01
Write freely
No prompts. No templates. Open the app and write. Every word is processed locally on your device.
02
Patterns surface
As entries accumulate, Hyperquery detects recurring words, tone shifts, and temporal patterns—your emotional fingerprint.
03
Insights emerge
You receive private observations: what you return to, what you avoid, how your tone drifts across days and weeks.
04
Nothing leaves
Zero network requests. Your data lives only on your device. No account. No backup. No leak vector.
Writing interface

The page
that listens.

Just write. No formatting toolbar. No word count pressure. The signals update silently as you type.

Emotional fingerprint

Every writer
is distinct.

Across 30 days, your word choices form a dot-matrix fingerprint. No two look alike. Yours is yours alone.

High-frequency emotional anchor
Recurring but not dominant
Low frequency — background
Echo words

The words
you keep returning
to.

Size reflects frequency. The words you use most often are the ones your mind circles back to—whether you notice it or not.

Silence score

What you
stopped
saying.

The absence of a word is a signal. Topics that vanished from your writing reveal what you are processing—or avoiding.

11 days since you wrote "future"
18 days since you wrote "happy"
34 days since you wrote "plan"
52 days since you wrote "love"
Insights

Patterns
made legible.

Generated entirely on-device. Shown only to you. Deleted when you want.

Temporal Detected · 30 entries
"You write 3× longer on Sunday nights than any other time."
Your longest entries cluster between 10 PM and 1 AM on Sundays. This is where your most unresolved thinking lives.
Linguistic Detected · 22 entries
"The word 'but' appears 84 times. Always before a doubt."
In 91% of cases, "but" in your entries precedes a sentence that contradicts something you just said you believed.
Emotional Detected · 45 entries
"Your emotional tone drifts heavy after 3 consecutive offline days."
A pattern visible only across entries—not within them. The drift is subtle until it is not.
Privacy

Your journal
is not a
data source.

Every other reflection app sends your writing to a server. Hyperquery never has a server to send it to.
