A rare expertise, built into a product.

Soulera's graphologists read handwriting by hand, one sample at a time. We built the model that measures every page, the mobile and web apps people use, and the portal where graphologists check every reading.

Graphology lives in a few people's eyes.

Soulera's senior graphologists have 9 to 23 years of practice and thousands of samples each. Every reading was done by hand: spacing, margins, slant, letter by letter. That's what makes it good. It's also why it can't grow past the people doing it.

The job was to build the product around the experts, not to replace them.

Four pieces, built end to end.

  • The modelFinds and measures the handwriting and signature parameters graphologists work from.
  • The mobile appUpload a page of handwriting. Get the insights back on your phone.
  • The web appThe same journey in a browser, for organisations and individuals.
  • The consultant portalWhere Soulera's graphologists review, correct and sign off every reading.

One page and a signature.

People write a page about themselves, photograph it with their signature, and get their report back in the app.

Eighteen parameters on every page.

A real page from the consultant portal. The red marks are the model's own output. The guides show four of the other things it measures.

  1. 1
    Left marginWhere the writing starts on the page.
  2. 2
    Right marginWhere each line stops.
  3. 3
    BaselineThe line the words sit on, and how it rises or falls.
  4. 4
    Line spacingThe gap from one baseline to the next.

Every handwriting parameter
  • Word spacing
  • Word and sentence count
  • Sentence spacing
  • Baseline
  • Left margin
  • Right margin
  • Margin
  • Noun and verb count
  • Capitals
  • Size of writing
  • Line spacing
  • Ballooning
  • Letter spacing
  • Slant
  • Type of handwriting
  • Zone height
  • Upper zone width
  • Lower zone width

Signatures get their own set, starting with finding the signature on the page.

Down to the letter.

Margins and spacing are the easy part. Graphologists also read how single letters are formed. So the model finds every a, d, g and t on a page, and tells one way of writing it from another.

Handwriting with each letter a boxed and labelled by its form, with a confidence score.
Each a, classified by how it's formed, with a confidence score.
Handwriting with every letter d boxed.
Every d on the page, found and boxed.
Handwriting with every letter g boxed.
Every g, loop included.
Handwriting with every letter t boxed.
Every t, wherever it falls in a word.

A graphologist checks every reading.

The model does the measuring. The portal puts its work in front of a graphologist, one parameter at a time.

Soulera's consultant portal: a list of handwriting parameters, the AI-annotated page, and a panel for the summary and the consultant's remarks.
  1. 01ParametersEvery parameter the model measured, one by one, each marked once it's reviewed.
  2. 02The model's marksThe annotated page, with the original one tap away, so the graphologist checks the model against the actual handwriting.
  3. 03Summary and remarksThe graphologist confirms or changes the reading, says whether the AI got it right, and adds remarks. That feedback goes back to the model.

The model measures. People interpret.

Spacing, margins and slant are measurements, and a model is good at measurements. What they mean is the graphologist's call. So the product is built that way round, and every correction a graphologist makes teaches the model something.

Turn your expertise into a product.

One honest hour.

Bring the expertise, the manual process, or the model that half works.

We tell you what AI can measure, and what should stay with your people.

Then we build it end to end.
