Free health tools, private by design.

Five free tools for staying healthy in India: a blood test report, the back of a food pack, a medicine strip, a doctor's prescription and the protein on your plate. Each one runs on your own phone or laptop, so what you put in never reaches us.

How we build our tools

The same four rules apply to every tool here, and to any we add later.

01

Your file stays with you

Reading happens in your browser. Nothing is uploaded or stored, so there's nothing of yours for us to lose.

02

Free, no account

No sign-up, no limits, and no ads inside the tools themselves.

03

Show the source

Ranges come from your lab, additive notes from regulators and studies, steps from official sites. We link them.

04

You check, a doctor decides

Each tool shows what it read so you can fix it. None of them diagnoses or tells you what to take.

Why you can rely on them

A health tool should earn trust with evidence, not adjectives. Here is what's under each one, who looks after it, and how you can check our privacy claim yourself.

Where the facts come from

  • ClearLab AI uses the reference range printed on your lab report. Where the sample needs a cutoff, it names the guideline (for example the ADA's HbA1c cutoff).
  • CleanBites notes come from FSSAI regulations, FAO/WHO JECFA, EFSA, IARC, WHO and the UK Food Standards Agency, each linked beside the flag it supports.
  • Prescription record spells out standard prescription shorthand, and its ABHA guides follow NHA's own portal at abha.abdm.gov.in and the ABDM FAQs.
  • Protein Calculator uses ICMR-NIN's recommended protein intake for Indian adults and food values from the Indian Food Composition Tables 2017. Ranges for older adults and exercise come from the PROT-AGE and ISSN position papers, which it cites.
  • Pill Identifier reads only what's printed or coded on the pack, following the labelling and QR-code rules in the CDSCO's QR code FAQs and the Drugs Rules, 1945.

Built on open-source readers

  • PDF.js, Mozilla's PDF reader (the one inside Firefox), opens lab reports.
  • Tesseract.js reads text from photos of food labels, medicine strips and prescriptions.
  • ZXing-C++, or your browser's own barcode reader, reads the QR code, DataMatrix or barcode on a medicine pack.
  • All of them run in your browser. Your browser downloads the reader code once; your file stays on your device.

Check the privacy claim yourself

  1. Open a tool on a laptop and press F12 (or right-click and choose Inspect), then open the Network tab.
  2. Read a file or photo.
  3. You'll see the reader's code being downloaded, and Google Analytics page views if you accepted cookies, but no request that sends your file anywhere.

Who looks after them

  • Built and reviewed by the Naked Compound Research Team, following our methodology.
  • Every change and correction is logged in public on our changelog.
  • No sponsor pays for a tool, a flag or a result, and we never sell or share anything you put into one.

Embed our tools on your site

Every tool here can run on your own website for free: a lab's results page, a pharmacy's help page, a nutrition blog. Your visitors get the full working tool, their files still never leave their device, and you don't need an account or an API key.

Pick a tool

  • ClearLab AI: reads a blood test report PDF. For labs, clinics and health blogs.
  • CleanBites: explains a food label. For food, fitness and parenting sites, gyms and schools.
  • Pill Identifier: reads a medicine strip. For pharmacies, clinics and elder care.
  • Prescription to Digital Record: turns a prescription into a tidy record. For clinics and caregivers.
  • Protein Calculator: daily protein and how Indian food adds up. For gyms, dietitians and fitness blogs.

How to add one

  1. Open the tool and scroll to Embed on your site.
  2. Choose light, dark or auto, and press Copy code.
  3. Paste the code into your page's HTML: a Custom HTML block in WordPress, an Embed element in Webflow or Wix, or straight into your template.

Embedding terms

  • Free for any site, personal or commercial.
  • Keep the credit line under the tool ("Tool name by Naked Compound") visible. You may add rel="nofollow" to it if your site's link policy needs that.
  • Don't change, cover or crop the tool, its privacy note or its disclaimers, and don't present its results as your own medical advice.
  • We improve the tools over time, and changes reach your page automatically.

For developers

  • The frame loads https://www.nakedcompound.in/tools/<tool>?embed=1. Add &theme=light or &theme=dark to fix the theme; otherwise it follows the visitor's device.
  • The optional /tools/embed.js (1 KB, no cookies, no tracking) listens for a nc-embed:height message from the frame and sets its height. Use your own listener if you prefer.
  • Links inside the tool open in a new tab, so your page stays put.

Questions about our tools

Are Naked Compound's tools really free?

Yes. There's no account, no subscription and no limit on how often you use them.

Do you see my blood report, food label, medicine or prescription?

No. Each tool reads your file inside your own browser. Nothing is uploaded to us or stored, and closing the tab clears it. The text reader is a free, open-source library your browser downloads once.

Can these tools diagnose a condition or tell me what to take?

No. They help you read and organise what's already on your report, label or prescription. For anything about your health or medicines, talk to a registered doctor or pharmacist.

Are you connected to the government's ABHA or ABDM system?

No. Naked Compound is independent. Our ABHA guides explain the official steps and link to abha.abdm.gov.in. We never ask for your Aadhaar number, an OTP or your ABHA login.

Can I embed these tools on my website?

Yes, for free. Each tool has an "Embed on your site" box with code to copy. Paste it into your page and your visitors can use the full tool there, with their files still read only on their own device. Please keep the short credit line under the tool.

Why did a tool misread my file?

Photos and scanned PDFs are hard to read, and handwriting usually can't be read at all. Every tool shows you the text it read so you can fix it, and you should always check the result against the original.

Reading aids, not medical advice. These tools explain what a report, label or prescription says. They don't test anything, diagnose, or replace a registered doctor, dietitian or pharmacist. Spotted a mistake or want a tool we haven't built? Tell us.
