Five lean modules. One data model.

The complete lean loop, finally on one platform.

Most plants stitch together a 5S app, an Excel defect tracker, a paper kaizen box, and a whiteboard for problem-solving. LeanOS unifies them — every module shares the same audit log, RBAC, photos, and leaderboard.

01
5S Audit

Walk a zone with your phone. AI suggests defects on each photo. Tap Keep or Ignore.

02
Defect Board

Open → Planned → Completed. Every defect has an owner, type, due date, and after-photo.

03
Fix Plan

AI writes a step-by-step procedure grounded in your past fixes. Cites which fix it learned from.

04
Kaizen

100% of the workforce can suggest an improvement. AI classifies category + savings range. Print as A4 with your logo.

05
Solve

Toyota A3 without the jargon: Background → Fishbone → 5-Whys → Countermeasures → Verify → Standardize.

How it works

Three honest steps. No paper. No spreadsheets.

01
Walk and capture

Pick a zone. Walk it with your phone. Each photo gets 0–3 AI suggestions. Tap Keep or Ignore — that's the audit.

02
Plan and fix

Defects land on a 3-column board. Owners assign type, fixer, and due date. Photos prove the fix.

03
Improve and standardize

Promote a stubborn defect to a Solve case (A3). Promote a clean fix to a Kaizen with savings tracking.

Why it works

Built for the failures of paper lean.

Most lean programs collapse for the same reasons: audits become one-off projects, no one knows what “good” looks like, and findings rot in a spreadsheet.

Paper / Excel
  • Quarterly audits, not weekly
  • Findings rot in PDFs no one opens
  • Repeat defects untracked
  • No proof a fix actually happened
  • Kaizens die in a paper box
  • A3s scribbled on a whiteboard
LeanOS
  • 5-minute walk → audit closes itself
  • Every defect has owner + after-photo
  • Repeat detection auto-flags repeat fixers
  • Kaizens with savings tracking, A4 print for the noticeboard
  • Solve cases with AI 5-Whys + Fishbone
  • Verified standards close the loop
For enterprise

One contract. Many plants. Zero spreadsheet exports.

From a 1-plant pilot to a 30-plant rollout — same product, same data model, same SSO and audit trail.

Multi-site hierarchy

Org → Site → Plant → Zone. One contract covers every plant.

Role-based access

Owner, Admin, Member, Auditor. Plant managers only see their plant.

Audit log + RLS

Postgres row-level security and an immutable audit trail every IT review will ask about.

CSV / Excel export

Defects, audits, kaizens, solves, activity log — one click, opens in Excel cleanly.

Built for global rollout

Multi-currency, time-zone aware, i18n-ready. Built for global manufacturing — North America, Europe, MENA, India.

Real native mobile

Android APK, sideloaded or via MDM. Works offline, syncs when network returns.

AI you can ground

Every suggestion can be ignored. Every fix plan cites the past fix it learned from.

A4 printables

Print Kaizen + Solve reports as official A4 with your org logo and QR code.

What teams say

Built with the floor, not the boardroom.

Replaced a 40-page audit binder with a 5-minute walk. Our shift supervisors started doing audits weekly instead of when the auditor visits.

Food & beverage manufacturing
The Kaizen savings tracking moved the conversation with the CFO from 'how many audits' to 'how much did we save this quarter'.
O
Operations Director
Pharma packaging
Solve module's AI 5-Whys actually gets to root cause. We finally stopped band-aiding the same defect every 60 days.

FAQ

The questions our buyers always ask.

How long is the pilot? Is there a credit-card requirement?+

30 days, no card required. Full product on one site. We help you set up your first plant and run the first round of audits with your supervisors.

Can it work offline? Our floor has spotty signal.+

Yes. The mobile app captures audits and defect actions to a local queue when offline. As soon as the phone hits Wi-Fi or cellular, the queue drains automatically — including photos.

Who owns the data? Where is it hosted?+

You own the data. Hosted on Supabase (Postgres) and Vercel. Your org is RLS-isolated — we cannot see your defects, photos, or members. EU data residency available on request.

How does the AI work? Is it accurate?+

We use Claude Sonnet's vision model. It returns 0–3 suggestions per photo — never auto-creates defects. The auditor confirms or ignores each one. For fix plans + 5-Whys + Fishbone, the AI is grounded in your plant's past data.

Can plant managers only see their own plant?+

Yes. Multi-site hierarchy with site/plant scoping is built in. Owner sees the org, Admin sees the org, Member sees their assigned zones, Auditor is read-only.

What's special about your A3 problem-solving?+

We follow canonical Toyota A3: Background → Fishbone (divergent) → 5-Whys (drilling into a chosen branch) → Countermeasures → Verify → Standardize. AI helps with 5-Whys conversation and Fishbone bucketization, but the team owns the case.

How is pricing structured at scale?+

After the pilot: setup fee + per-seat/month annual prepay, with PPP-adjusted regional pricing. Operator seats are inexpensive; manager seats with reporting are higher. Contact us for a quote.

Stop running lean on paper.

Your first audit takes 5 minutes. Your CFO sees the impact this week.
