AI + Hume Health: read the whole band, not one more score.

The Hume band tracks sleep, heart rate, recovery and body composition — then hands most people a daily score and a nudge. A small stack of free AI tools lets you read the data underneath, across every metric at once, and decide what actually matters.

One method, not one more app

Hume Health is the data source. The method is what turns that data into something you can read, question and act on — the same three layers, whatever app or device you happen to use.

  1. 01

    Research

    Sourced search that ranks real evidence above influencer claims — so you start from what the studies actually say.

  2. 02

    Ledger

    One long-context record of your own data and notes, re-read together week after week, so patterns surface instead of scrolling past.

  3. 03

    Protocol

    A single, constraint-aligned plan that fits your real schedule — one thing to change, not a textbook to obey.

“But it already has AI built in.”

More wellness apps and wearables are doing exactly that — building a capable assistant straight into the app. It is genuinely useful, and it changes nothing about why this method exists.

A built-in assistant can only see one app’s data, and it answers inside the frame of the company that built it. Your sleep, your labs, your training, your cycle and your notes still live in separate silos — and the questions that matter most sit in the gaps between them.

The method works the other way around. You bring the data out, into tools you own, and read it across every source at once. When an app gets a smarter assistant, that’s one more good input to your stack — not a new dashboard to be governed by.

Four tools, one workflow

  1. 01

    Hume Health band + app

    The sensor. Records sleep, heart rate, recovery and body composition — and lets you export the series.

  2. 02

    Your chat assistant (ChatGPT / Claude / Gemini, free tier)

    The analyst. Reads an export and correlates your best and worst days against what you logged.

  3. 03

    Your notebook tool (NotebookLM)

    The memory. Holds months of exports and your own notes for cross-week, cross-metric questions.

  4. 04

    A scheduled action / custom agent

    The ritual. The weekly nudge that drafts your read-out and keeps the loop running.

What the band actually gives you

Worn day and night, the band records a steady stream: sleep stages and total sleep, resting heart rate and overnight heart-rate variability, recovery and strain, plus body-composition readings from the wider Hume ecosystem. The app turns most of that into a score and a suggestion.

The series underneath the score is the valuable part. Export it and you are holding weeks of your own physiology in a format an AI reads like a spreadsheet — which is exactly what makes the next step possible.

One reading across every metric

A score looks at one slice. The questions that change anything live in the gaps between slices: does your recovery actually drop on the nights you train late, does a heavy week show up in heart-rate variability before you feel it, does body composition move in line with the effort or just the hydration.

A built-in assistant answers questions about the band. The method teaches you to read the band alongside your sleep, your labs, your training log and your own notes — in tools you own. Same data, wider lens, and you stay the one deciding what it means.

Research → Ledger → Protocol, on a band

Research one variable properly with a sourced-search assistant, so you start from what the evidence says. Build a ledger by exporting the band weekly and adding a sentence of context. Run a protocol — a single change, held for a fortnight — and let the AI read whether the trend actually moved. The band measures; you decide what counts.

Three prompts you can use today

Paste each into the chat assistant you already use, along with this week’s Hume Health export.

Weekly read-out

Here is this week's Hume export plus last week's for comparison: sleep stages, resting heart rate, heart-rate variability, recovery and body composition by date. Summarise in five bullets what changed and the most likely cause. Flag anything to simply keep an eye on. No diagnosis, patterns only.

Spot the anomaly

I'm pasting 8 weeks of Hume data. Compare this week against the prior four and surface anything genuinely unusual in my recovery, heart-rate variability or sleep. Rank by how far it sits outside my normal range. Do not diagnose — tell me what to watch and what to ignore.

Practitioner handover

Turn the last 90 days of my Hume data into a short, structured note I can take to my doctor or coach: the trends that matter, the questions they raise, and what I have already tried. Plain language, one page, no medical conclusions.

Before you paste anything

  • Never ask AI for a diagnosis. It reads patterns; it does not practise medicine.
  • Strip names, emails and any clinical ID before you paste an export.
  • Only paste your own data — never anyone else's.
  • Treat the output as a hypothesis to test, not an instruction to follow.
  • If a pattern worries you, take the written summary to a clinician — don't act on it alone.

Common questions

Do I have to leave the Hume app to use this?+

No. Keep the band and the app — including its built-in assistant. The stack sits above them: you add a reader that works across all your data, in tools you own.

Which chat assistant should I pick?+

Any of the major free assistants can read a CSV. Use the one you already use; the method is identical across them.

Is it safe to paste my Hume data into AI?+

Strip names and IDs first and it's just numbers and dates. Use a free general-purpose tool and never paste anyone else's data.

Can this replace my doctor?+

No, and that's the point. It hands you a clean written summary to bring to a clinician — better questions, not a substitute for answers.
