AI automation

for small businesses in Japan

IsauLab (イサウラボ) builds secure, simple AI automations for small businesses and shops in Japan. From ready-made templates to custom builds, everything happens online.

No meetings. Everything is handled by email.

What we do

Replying to inquiries, answering reviews, filing paperwork: we hand the repetitive daily tasks to AI and automation tools. You keep using LINE, Gmail and Google Sheets the way you already do. We just connect the pieces.

Customer inquiriesAuto-reply to common questions on LINE or email, and get notified only when a person is needed.
Review repliesAI drafts polite Japanese replies to Google reviews. You approve every reply before it's posted.
Invoices & paperworkInvoices and receipts that arrive by email are read, filed into folders and logged to a sheet automatically.

How it works

Everything happens by email. We aim to reply within two business days (JST, excluding weekends and Japanese holidays).

  1. Tell us what you need

    Describe your current process and the tools you use in the request form. No passwords needed.

  2. Get a quote by email

    We ask any clarifying questions, then send a quote with a clear scope and a fixed price.

  3. Pay and we build

    You pay only once you're happy with the quote. We build safely using sample data.

  4. Handoff

    You connect your own accounts, and receive a runbook plus the steps to switch everything off.

Our security commitment

Every IsauLab automation is designed and reviewed before delivery by an engineer who specializes in cybersecurity. Safety comes before convenience.

  • We never hold your passwords

    You connect your own accounts using OAuth or API keys you can revoke at any time.

  • Least privilege

    We request only the access each workflow needs, and every permission is listed in your handoff guide.

  • Separate environment per client

    Each client's build runs in its own isolated environment. No data is shared between clients.

  • Sample data while building

    We build and test with sample data, not your real customer records.

  • Careful with AI and personal data

    Personal data goes to a cloud AI only with your written consent, and only to providers that don't train on API data.

  • Easy to switch off

    You always get the steps to stop the automation and revoke access. Your data is deleted within 30 days after the contract ends.
