§ 01 — The products

What we build, plainly.

PRODUCT 01

oneceylon.space

The travel platform for Sri Lanka. A community Q&A where locals and experienced visitors answer the questions guidebooks do not — plus collaborative itineraries, a verified marketplace of guides, drivers and hosts, scam alerts, tuk-tuk fare checks, and travel writing by people who actually live here.

PRODUCT 02

SerendAI

The travel assistant that lives inside OneCeylon. SerendAI reads the weather forecast, the bus timetable, and the Sinhala or Tamil sign in a visitor's camera roll — then answers in whatever language they are asking in. It identifies the food on a plate, flags a scam before it happens, and shows where the tuk-tuk should actually be charging.

PROPERTY 03

oneceylon.tech

The house journal. Engineering notes, applied research from the team working on SerendAI, and every role we are hiring for, with no middleman. If you want to know what we think before you work with us — or for us — start here.

§ 02 — Why this exists

A traveller in Sri Lanka has too many tabs open, and none of them quite fit.

Tourist forums rot. Facebook groups scatter. Official tourism sites read like a press release. Meanwhile the actual questions a first-time visitor has — is this tuk-tuk fare fair? what is this fish on my plate? which train gets me to Ella before dark? is that sign a warning or a welcome? — go unanswered until someone kinder and better-travelled stumbles past.

We built OneCeylon to put that kinder, better-travelled person in everyone's pocket.

The platform is a working Q&A community, Stack Overflow-shaped, for people planning or currently in the middle of a trip. SerendAI sits alongside it, answering the questions that are too immediate to wait for a human — the weather on Adam's Peak at 4am, the Sinhala writing above a pharmacy door, whether the currency note in your hand is a 500 or a 5,000.

One platform. One answer. In the traveller's own language.

§ 03 — From the notebook

What the engineers are writing.

RESEARCH April 2026 · 10 min read

Teaching SerendAI to read a Sri Lankan pharmacy sign at 9pm.

A field report on multilingual photo translation for travellers. How we got from "unusable on real street signs" to something a visitor in Nuwara Eliya can trust after dark — and the preprocessing trick that finally moved the numbers.

§ 04 — How we work

Four rules, written on the wall.

01

Answer the actual question.

Travellers do not care about our architecture diagrams. They care whether the train to Ella leaves at 8:47 or 8:57. We build backwards from that.

02

The island is the spec.

Our users are on 3G in a moving tuk-tuk. Our guides speak three languages. Any software we build has to respect the real conditions of travel here — not an idealised version of them.

03

Community, then clever.

A verified answer from a local in Galle is worth more than the best model we can fine-tune. SerendAI is clever. The community is right.

04

Stay on the island.

The best software for Sri Lankan travel will be built by people who live here, on problems they understand first-hand. That is the whole thesis.

§ 05 — What next

If any of this sounds
like your kind of work,

we are hiring two people right now. One senior, one just starting out. Both will shape what travellers see when they come to Sri Lanka.
