Less guessing.

A clearer picture of your gut’s daily patterns.
We’re building AGNI, a gut-health wearable with a companion app, to explore signals alongside meals and everyday context. Working engineering prototype. Clinical usefulness still to be tested.

No gut score. No food verdict. Just the idea of a better record.

Less guessing.
More context.
Open a step to explore what we’re building.
01 Capture a signal ↗
Acoustics, motion and skin temperature. First, establish whether the recording is reliable.
02 Keep life attached ↗
A signal alone isn’t the story. Meals and self-reported experiences give it context.
03 Ask better questions ↗
Compare your days—not your body to a universal score. Any useful interpretation still needs validation.

Your digestion still lives
mostly in memory.
Let’s keep a better record.
Memory is a terrible lab notebook. A meal, a restless night, a busy afternoon: the context matters. We’re exploring how to keep it beside the signal.
FIELD NOTES / OCTOBER 2026Big questions.
Big questions.
Honest boundaries.
A working prototype is a beginning. Here’s what we can build on—and what we still have to earn.
Make the invisible
Your days.
Side by side.
Explore meal-linked acoustic changes and symptom diaries. Optional cycle and sleep logs add context, not automatic predictions.
Follow the evidence ↗No shortcuts
to certainty.
No diagnosis, microbiome readout, fertility prediction or sleep staging. More sound does not automatically mean better digestion.
Ask the hard questions ↗NEW RESEARCH NOTE
A 2026 SonicGuard preprint explores expert-labelled acoustic event detection. It guides a question—not a performance claim for ANTRAM.
Read the preprint ↗02 / HOW IT’S BEING BUILTThree signals.
Three signals.
Your context. Zero verdicts.
A wearable worn on the abdomen.
A record that keeps everyday life attached.
Every useful output still has to be validated.
01 / LISTEN Acoustics
The sound
of a question.
Investigating whether abdominal sound activity can be captured reliably through daily life.
Signal quality: under validation02 / MOVE Motion
Life moves.
So does the signal.
Movement context helps us study noise and changes in posture.
03 / TEMP Skin temperature
Another layer
of context.
Surface temperature is a supporting signal. It does not measure core temperature.
04 / YOU The part only you know
There’s no sensor
for “one more chai.”
Rajma chawalChai #3Deadline weekSlept badly
Meals, symptoms, stress and sleep. A few notes help make a record worth revisiting.
THE BOUNDARY
Gut scores.
Diagnoses.
Food verdicts.
A repeated association doesn’t establish a cause. Severe, sudden or worsening symptoms need medical care.

Three afternoons that look alike can be a question worth writing down. A pattern isn’t a cause or a diagnosis. This example was generated to demonstrate the idea; it says nothing about your health.

06 / FAIR QUESTIONSA little less
A little less
guesswork.
Is this a diagnosis?+
No. AGNI cannot diagnose a condition or identify a trigger food. Its proposed outputs require validation. A repeated association cannot establish cause.
What exists today?+
We have a working hardware prototype and are incubated at SRM BioNEST. We are investigating signal quality and feasibility. The day demo is entirely synthetic. Field Notes separately presents credited external research recordings, not ANTRAM measurements.
What is the wearable intended to measure?+
Abdominal acoustic activity, movement and skin temperature. The usefulness of these signals together is a research question. Skin temperature is not core body temperature, and low motion alone cannot establish sleep.
Can I use the check-ins now?+
Yes. They provide prompts to reflect on your own context. Your answers stay in your browser. They do not diagnose symptoms or substitute for medical care.
Does the demo record me?+
No. The Listening Room generates its sound in your browser. It has no microphone access and uploads no audio or stickers.
Can I buy AGNI or join a study?+
AGNI is in development. The lab notes list is for product updates, not clinical study enrolment. Any future research recruitment will follow the applicable approvals and consent process.

We’re looking for practitioners who support adults with recurring digestive discomfort. Our first ask is a short conversation about gaps in the record between appointments.
- What is hard for people to recall or log?
- What would change a useful conversation?
- What would a wearable need to prove beyond a diary?
