See it live: the full presentation, with a working Gol you can question, is at https://luckymart.biz/presentation/

Gol is an AI operator: it runs a small shop's point of sale, back office and store website — by conversation. Stop operating software. Talk to your business. Gol operates the systems for you.

The cashier works in fragments, one hand on the counter, often in a language the software was never written in — and a shop that cannot record its numbers cannot trust them.

Gol is not another register; it is the operator who runs the register, the back office and the website — built from scratch in this hackathon (first commit October 26, 2026; gol-pos repository). Its newest face is the till screen, joining MR.STORE and the founder's store websites. A real client, Palm It (Itahari, Nepal), runs its own node on palmit.com.np. On submission morning, founder Ashish Adhikari handed the agent an unseen hosting account for Himalayan Corridor, his travel platform — the node was installed end to end: gol.himalayancorridor.com is live.

One brain, many shops: each business is its own node. Before answering, the server assembles that shop's live context pack — catalog, stock, sales, bills, people — and Gol reasons over it alone. Requests become structured intents that deterministic code validates and executes: a model may be wrong about words, never in charge of money. Changes are staged as cards, written only on the owner's confirm word "gol"; a cancel writes nothing.

Three faces of one operator: customers on the store website, the cashier at the till, the owner in the back office — the books kept by talking. Verified live on the QA store (November 3, 2026): an "expense 12 ice" entry was staged, confirmed and read back from the ledger — amount, date, store, status all matched.

At the till: a 62-item catalog grid, barcode entry, per-line cart, configurable tax, and a tender panel the server re-verifies — under-tenders refused. Where thinking is needed, the cashier talks: Gol adds unscannable items by name, answers prices live, and reports the day's totals and cash/card split.

It speaks the shop's language: English by default, Romanized Nepali, Devanagari and Hindi answered in kind. If the model API fails, a deterministic resolver answers from live data; writes never depend on the API.

Proof, not promises: a 60-case brain battery (six intents, three languages, plus language mirroring) passed 60/60 on October 26; settings and owner-door batteries passed 13/13. Tender verified line by line on October 27: $6.67 + $0.53 tax = $7.20; $10 tendered, $2.80 change; an under-tender refused, nothing recorded. The demo catalog is the fictional Sunrise Mart seed.

Where it stands: soft launch — live in the founder's two shops, one real client, and the Himalayan Corridor node, hardened daily.

Roadmap (not built, not claimed): self-serve installer, payments hardware, multi-store sync, existing-POS connection, purchasing, payroll.
