Lumi / For finance
For accountants and finance
A quarter closed. Last quarter remembered.
Lumi reconciles, explains and drafts on your own PC, with every figure traced back to the ledger row or statement page it came from.

A quarter-end reconciliation in the Lumi app, in agentic mode. Scripted example files.
What it found, and where
In the example above, Lumi matched 1,284 transactions between a general ledger and three bank statements and explained the seven differences over $500: a $9,800 payment booked twice (GL rows 412 and 419, shown once on the August statement, p. 3), $4,150 of card fees not posted, and five timing items that cleared by 9 October. It also remembered that the same supplier was double-booked in Q1, because you flagged it in an earlier chat, and delivered the reconciliation and a draft note to the client.
Annual reports, read to the page

Ask why operating margin fell and whether a covenant is at risk. Lumi pulls the tables, builds the margin bridge chart, checks net leverage against the limit, and cites the page for each figure.
More of the work it takes off your desk
- Spreadsheets out, not just answers. Variance tables, reconciliations and schedules as real files.
- Client letters. Draft from your templates, or mail-merge a batch from a spreadsheet.
- Memory across quarters. Encrypted on your PC; ask what you flagged last quarter and get the answer with its source.
Where client data goes
Nowhere. Ledgers, statements and reports are read on your own graphics card and stored encrypted on your own disk, never uploaded to a server. The only things that go out are what you explicitly ask Lumi to fetch, like a web search or a new model.
What you need
A Windows PC with an NVIDIA RTX graphics card. One installer: no Python, no command line.
Questions
Can Lumi reconcile bank statements against a ledger?
Yes. Lumi reads the ledger and the statements, matches the transactions, explains each difference with the row or page it came from, and delivers the reconciliation as a spreadsheet.
Is client financial data uploaded anywhere?
No. Lumi works on your own PC and stores everything encrypted on your own disk. Nothing goes out unless you ask Lumi to fetch something, like a web search.
Does Lumi work on Windows?
Yes. The private beta is for Windows PCs with NVIDIA RTX graphics, where most accounting work already happens.
