MENTO Prototype

ものづくり — the spirit of making things well

Experience becomes expertise.

Manuals explain the standard steps. MENTO captures what they cannot: why a master does things their way, how they know a moment is right, and what they change when conditions change — and turns it into lessons the master approves.

See how it works

問

Asks why, not what

The AI watches the demonstration and asks about the reasons, instincts and judgement a manual can't hold.

承

The master has the last word

The AI only drafts. Students see nothing until the master has checked and approved it.

工

Lives in your workshop

Runs on your own computer with a phone as the camera, in English or Japanese.

The problem

The most valuable knowledge is never written down.

  • Senior craftspeople retire and their know-how leaves with them
  • Training newcomers takes the best people away from their work
  • Manuals capture the steps, never the judgement behind them

How it works

Four simple steps from master to apprentice.

  1. 一 · 01

    Master demonstrates

    The master records a real task on a phone. No studio, no script.

  2. 二 · 02

    AI asks

    The AI finds the key moments and, using the manual as background, asks about what the manual does not explain.

  3. 三 · 03

    Master reviews

    Typed or spoken answers become knowledge drafts. Only what the master approves is ever shown to students.

  4. 四 · 04

    Student practices

    Students join with a code, study the lessons and practise with camera checks tied to the master's own clip.

Why MENTO

Built on trust, not guesswork.

Grounded answers only

Every tip a student sees comes from knowledge the master approved. If the evidence is unclear, MENTO says it cannot assess.

Human in the loop

Students' questions go straight to the master. The AI only drafts; nothing is approved automatically.

Local-first

Runs on your own computer: vision AI, speech-to-text and read-aloud voices. Cloud AI is optional and always falls back to local.

Private by design

Consent on every device, personal master accounts and per-session invitations keep recordings inside your workshop.

Ready-made skills

One platform. Any craft.

Each skill is a simple profile of tasks, tools, safety notes and a short manual. Four come ready to use; masters can describe their own craft in a minute.

Technical

Under the hood.

One reusable engine. Skills are configuration profiles, not separate apps. Everything runs locally by default.

Private by design

  • Video, audio and knowledge stay on the master's computer. The AI (vision model, speech-to-text and read-aloud) runs locally, with no cloud AI.
  • The AI never decides why the master did something: it asks, and the master's own words are kept and labelled.
  • Students only ever see knowledge the master has approved.
