examples / four graphs, four sentences

Use cases

Nolvin is generic by design: nothing in the pipeline knows about festivals or funds. These graphs run in production today; each started as the one sentence shown.

01 / 04events · calendars

An event calendar that fills itself

prompt

“Tantric events in Sweden”

Festivals, workshops and retreats are announced across dozens of small organizer sites, each with its own calendar format. From one sentence, Nolvin found the organizers, read their programmes and built a dated timeline of events linked to teachers, venues and associations — and re-reads each calendar daily, so new dates appear without anyone copying them over.

for — Event aggregators, community sites, tourism boards, newsletters.

02 / 04companies · regions

A local industry map

prompt

“Tech consulting firms in Linköping and Norrköping”

Which consultancies actually have an office in the region, who leads them, and which science parks and networks connect them? The graph links firms such as HiQ, Knowit, Sogeti and Combitech to Linköping Science Park, their local offices and the people who run them — the kind of picture an industry directory never keeps up to date.

for — Regional development agencies, recruiters, sales teams, analysts.

03 / 04capital · networks

An investor network

prompt

“Swedish VC and business angels + angel networks”

Funds, angel networks and the people behind them, from Connect Sverige and Industrifonden to Creandum and Norrsken VC — with who invested in what, who is a member of which network, and where they are based. The canonical invested_in and member_of relations make the network queryable in one request.

for — Founders raising money, accelerators, ecosystem mappers, journalists.

04 / 04culture · places · contact info

A cultural scene with contact details

prompt

“Japanese crafts, arts, cooking, materials, courses, et cetera, with a presence in Stockholm, Sweden; locations, contact info, descriptions.”

Museums, tea societies, knife shops, cooking courses and exhibitions — Etnografiska museet, Östasiatiska museet, Japanska Thesällskapet — mapped with their events and venues. A prompt that asks for contact info gets email and phone attributes on the domain, filled only with details printed on the organizations' own pages.

for — Culture guides, city portals, associations, embassies.

What else people build#

  • Research landscapes — labs, principal investigators, grants and conferences in a field.
  • Supplier and competitor maps — companies in a niche, their products, locations and partnerships.
  • Civic and nonprofit directories — associations, their boards, meeting places and events.
  • Grounding for AI agents — a sourced, current graph an assistant can query and cite instead of guessing.

Each is a domain with its own gate, sources, budget and API. See how the pipeline works or go straight to the quickstart.
