The workbench where plain English keeps the books.

This is the product's own interface with a sample company loaded. Say what happened β€” "log the June office rent, 28,000 from HSBC" β€” and watch it become a ledger row, a reconciled statement line, and an audit trail. Click through the sidebar; press the suggested prompts in the chat.

How to drive Suma day to day.

1 Β· Say what happened

"Paid 1,240 to MTR Corporate for travel" β€” the assistant picks the sheet, the row and the category from your workflow rules, and posts it.

2 Β· Ask for any number

Totals, comparisons, who owes what. The assistant computes on the sheet with real formulas and shows its evidence β€” no invented figures.

3 Β· Everything is undoable

Every change the assistant makes is listed in the reply and reversible in one click.

Workflow

Your company's own rulebook β€” the assistant follows it on every entry.

Workflow set
1. Freight and packaging invoices β†’ Expenses, category "Freight" or "Materials". 2. Rent, storage and utilities β†’ category "Rent & storage" / "Utilities", paid from HSBC operating. 3. Any single expense over HKD 20,000 β†’ flag for review before posting.

Is this the real product?

It's the product's interface running a scripted sample company in your browser. The full workbench β€” live model, receipts, exports, undo β€” ships to clients.

What leaves my computer when I use Suma?

Client and vendor names are replaced with pseudonyms like VENDOR_1 before any request leaves the app; totals are computed locally on the sheet. The mapping never leaves your device.

What you just saw

An assistant that posts entries β€” and proves its numbers.

Two different jobs, handled two different ways. Recording is instant. Answering is evidence-first: the assistant reads the schema, computes on the sheet with real formulas, and answers only from what it found.

Entries

Plain English in, posted rows out.

  • "Log the June office rent, 28,000 from HSBC" becomes a dated, categorised row β€” one step, no forms.
  • Your company workflow is the rulebook: categories, accounts and approval thresholds are applied automatically.
  • Every change is itemised in the reply and reversible.

Privacy, by construction

Names stay in the room.

  • Before any request leaves the app, client and vendor names become stable pseudonyms β€” CLIENT_1, VENDOR_2.
  • Totals and averages are computed locally on the sheet; only the result travels.
  • A deterministic audit checks every outbound payload; if anything sensitive would leak, the response is stopped.
