ScreensConcept
Desktop app: Developers configure APIs and build integrations, review detailed pagination logic, and manage complex formatting rules—work that requires a full keyboard and screen. Sample screens on a computer, in the proposed brand. Their numbers are sample data.

About this appAI proposal
Galleyproof turns plain text or markdown into publication-grade PDFs through an API or a command line. It shapes mixed-language text correctly and applies page rules that depend on context, such as continuation markers when a scene or a speech breaks across pages.
It is for developers, screenwriters, publishers and content teams who now write in text and then paste the result into proprietary software to get an industry-standard layout. Galleyproof removes that last manual step.
Layout is not a black box. Rules live in a readable file, each page break can be traced to the rule that caused it, and the same input always gives the same PDF.

- Why this name
- A galley proof is the trial sheet checked before the final print run. The name points to typeset pages that come out right the first time.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Multilingual text shaping
Mixed scripts and right-to-left runs in one document are shaped correctly, with per-language font fallback.

What it could be worthEstimate

If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Screenwriters and publishers send PDFs to readers, agents and printers. An optional footer credit and a shareable proof link carry the name to people who receive the file.
- Do they become customers?
- Recipients are mostly readers, not buyers. Test whether writers and developers among them click through and sign up, and whether the credit is accepted.
- First customers
- Developers and screenwriters who write scripts in plain text and need multilingual, industry-format PDFs, starting with small indie film and publishing tool builders.
- Where to reach them
- Hacker News follow-up: Post a demo to the people in the original thread showing a mixed-language script with continuation markers.
- Screenwriting communities: Offer free renders in forums for text-based screenwriting and multilingual production.
- Open-source repositories: Publish the CLI and a sample rules file, and link to the hosted API.
- First milestone
- Ten paying users on the Developer plan, with at least three producing multilingual scripts.

RisksAI inference
- TechnicalCorrect shaping and bidirectional layout across many scripts is hard, and industry screenplay rules have edge cases. A narrow first scope is needed.
- CommercialDevelopers may keep using free libraries or their existing screenplay software. The material shows interest but no proof of willingness to pay.
- Intellectual propertyFonts carry licences, and industry layouts may follow other products' conventions. Licences and presets need review.
- CommercialThe source is one discussion thread with public claims, so demand outside it is unverified.
