Your AI. Your books.
The lejr you can talk to.
Keep your small-business books by asking. Connect Claude — the assistant you already pay for — and lejr turns “I bought a forklift for $75k” into proper double-entry bookkeeping, ready for tax season.
The inversion
Clicking through menus is not how you think about your business.
The others
47 clicks
to categorize 100 bank transactions — one at a time, through a dropdown menu.

one sentence
“Categorize all Shell and Chevron transactions as Fuel.”
Bring your AI
Built for Claude.
lejr plugs into the Claude assistant you already use. Generate a connection once, paste it into Claude, and your assistant gets a new skill: keeping your books.
We built on Claude first because the connector experience there is the cleanest today. No plugin to install, no browser extension, no new app to learn — just talk to Claude the way you already do.

The books are the books
Built like real accounting, not a spreadsheet with a chatbot.
Balanced
Your books can’t drift out of balance.
Every entry has to balance to the penny before it’s saved. lejr won’t let you skip that — and neither will your AI. It’s the whole reason double-entry exists.
Immutable
Nothing gets quietly edited.
When something changes, the original entry stays, and the new one points back to it. Your accountant — and the IRS, if it ever comes to that — see the whole story, not just the final number.
Audited
Every change is on the record.
Who asked, what they asked, what lejr did, and when. One screen, in plain English. If you ever need to explain a number a year from now, it’s right there.
CPA-ready
Made for your CPA, not against them.
Your accountant can open the books, pull a trial balance or general ledger, and reconcile without fighting the app. Export to QuickBooks or Xero is on the roadmap — you’re not locked in.
Pricing
One plan. One price.
No feature tiers. No per-entry fees. Whatever your AI can do, your ledger can handle.
