One production system, three commercially useful assets.

The generator and editorial pipeline are the core value. The puzzle library provides immediate usable inventory, while the app demonstrates that the content can be deployed, distributed and monetised in a real consumer product.

01 / Core technology

Generator and editorial pipeline

Construct themed and themeless grids, control fill quality, generate clues, run deterministic and editorial checks, repair failures and prepare production output.

Commercial validation without disclosing the client.

The production workflow has been used and refined in an external commercial publisher context. Client identity and confidential production details are not disclosed publicly.

Generation is only the first stage.

The commercial value comes from controlling what reaches the buyer: grid quality, clue fairness, publisher fit and auditable production evidence.

01

Construct

Build themed or themeless grids against the target format and structural rules.

02

Control fill

Apply lexicon quality bands, crossing constraints and entry-level exclusions.

03

Generate clues

Create clues against answer sense, audience level and publisher conventions.

04

Audit and repair

Run deterministic checks, editorial QA, targeted repairs and a stability review.

05

Deliver

Produce structured data, grids, clues and agreed export files with trace evidence.

What prospects usually need to establish.

Commercial discussions can move quickly once the output specification, evaluation route and intended use are clear.

Yes. Clue style, difficulty, vocabulary rules, audience assumptions and export requirements can be defined as part of a commercial implementation.

No. Current proven capability should be distinguished from sizes that require additional packaging or implementation. New formats can be scoped commercially rather than presented as finished features.

Yes. A structured paid technical evaluation can provide controlled access to source code, documentation, benchmark evidence and selected production artefacts.

The commercial structure can be discussed, but the principal routes presented here are generator licensing and complete acquisition of the wider asset package.
