Repetitive back-office work, made lighter

Repetitive work your teamcan no longer absorb.

For document and data checks that business software and general-purpose AI tools do not handle well,
we rebalance the work between people, AI and your existing systems — cutting cost and load.

Problem

What teams buried in document and data checks run into

Peak season

  • As volume grows, deadlines stay tight even with overtime and temps

Deadlines get tight

Rule changes

  • Misses slip through while staff relearn the criteria

Misses slip through

Staff leaving

  • When someone leaves, work stalls until the handover is done

Handovers stall the work

Services

Move repetitive work from people to AI and decision rules.
Decide, pilot and run, end to end.

Decide

We take in your rules and documents,
and the AI reads them

We start from what you already hold — rules, manuals, specifications — and load them into the app.
Where the documents leave a gap, you answer the AI’s questions.

Decide

We separate what AI can take,
with the basis shown

We break the task into steps and separate what AI can take from what people should keep.

Pilot

We set up the app on your rules,
and AI processes every case

You hand over the rules and the source documents; we configure the app and the AI processes every case.
No system integration is required to start.

Pilot

Only the cases that need a look
are confirmed in the app

The source, the AI’s reason and the clause it relies on sit on one screen, and we confirm with a button. Only split decisions come back to you.
What was confirmed, and why, stays on record, and from then on the AI drafts its proposals on that basis.

Pilot

You decide on production,
with the report in hand

The report shows the share cleared automatically, time spent checking, and misses, measured on your real data, with costs compared to today.
You can also decide not to move to production.

Run

In production, the confirmed
decision rules carry over

From here, your staff can confirm in the app, or we can do it for you.
Decision rules and per-case records stay with you, so a change of staff does not reset the work.

Use Case

Use cases for repetitive clerical work

Tasks in scope

Transfer

HR & General Affairs

  • Sorting applications by role
  • Applying internal rules to cases
  • Transcribing savings and group-insurance filings

Finance & Purchasing

  • Assigning account codes to receipts
  • Cash application
  • Three-way match of order, receipt and invoice
  • Drafting payment reminders

Inquiry desk

  • Routing inquiry emails
  • Drafting inquiry replies

Local government

  • Screening benefit applications
  • Drafting decision notices
  • Entering change-of-address forms into the register

Universities, logistics & construction

  • Checking research expense receipts
  • Explaining stock-count differences
  • Updating project ledgers

The 15 tasks were checked on sample data and are not customer results. Departments are examples.
Work that business software already covers (attendance, payroll, year-end adjustment) or that a general-purpose AI tool handles in one go (a single email, a one-off tally) is out of scope.

Trust

Our founder, an AI engineer, personally handles
the product and the 4-week pilot.

How your data is handled

Processed and stored in Japan

Your data is processed and stored on cloud infrastructure located in Japan.

Never used for training

We use AI services configured so that input data is not used for model training.

NDA and least-privilege access

An NDA is signed before we begin, and access is limited to the assigned staff.

Return and deletion

Storage location, retention period, and return or deletion at the end are agreed in writing before we begin.

FAQ

Frequently asked questions

Q. What kind of work is in scope?

A. Repetitive clerical work where documents or data are reviewed case by case against your own rules — sorting, deciding, reconciling, drafting and transferring. Work that business software already covers, such as attendance or payroll, is out of scope.

Q. Do you need to connect to our core systems?

A. No. Data can be provided as CSV or Excel exports.

Q. What do you measure during the 4-week pilot?

A. The share cleared automatically, the share sent to people, time spent checking, misses, and whether deadlines are met — all on your real data, with costs compared to today. The pass criteria are agreed before we start.

Q. What if we cannot release real data?

A. We can work with masked data, with personal details removed. If even that is not possible, we can run on data modelled on your own forms — but then we can confirm the flow and the human workload only, not measure accuracy.

Q. Can we stop after the pilot?

A. Yes. You can decide not to move to production after seeing the report. If a task is a poor fit, we say so before starting.

Get Started

Start with a 30-minute call.

Start with the rules and documents you already have. We confirm one task in a 4-week pilot.

In a 30-minute call we look at which repetitive tasks qualify,
what the report would show, and what a first engagement would involve.
