I’m Christian Murphy and Chrono X is my one-person software company in Melbourne. I make Substrike and a few free tools. I also build websites, online stores and software to order.

Redact

Finds the names, phone numbers and addresses in a recording or transcript so you can take them out before you share it. It runs in your browser and the file is never uploaded.

Custom

I build websites, online stores and small programs for the jobs you do by hand every week.

Most of those jobs are the same task done over and over. Often the fix is a small program that reads an inbox or a folder of PDFs each morning and puts the result where it belongs. Sometimes it’s transcription or document search that has to stay inside your office because the files can’t go to a cloud service.

Send me a paragraph about the job. Within three working days I’ll come back with how I’d do it and a fixed price in writing. That price doesn’t change. You own what I build.

Things I’ve built

  • Websites and e-commerce stores for myself and others, including this one.
  • Android apps for terrestrial and satellite set-top boxes and the operating system they ran on.
  • A tool that pulls my work roster out of my inbox and puts it in a shared calendar every morning.
  • Substrike, Redact and StoreGrades.

About

I'm Christian Murphy. Before Chrono X I was in senior product management and led technical support. I was also the advisor on compiling and developing Android operating systems and applications for satellite and terrestrial products, and I wrote their user manuals and technical documents.

Outside of software, I make music in my spare time as a vocalist, guitarist and pianist and still release music today.

Chrono X is just me, a one man band. So you deal directly with me from the word go.

Questions

Are my files uploaded anywhere?
No. Substrike and Redact download their speech model once when you first use them. After that the transcribing happens on your computer and your files stay there.
Is there a subscription?
No. You buy a licence once. The price is on each product's own site next to the download.
Does it run on a Mac?
Redact does because it runs in your browser. Substrike is Windows only for now. If enough people ask for a Mac version I'll build one.
Who handles payment?
Paddle runs the checkout. They're the merchant of record so they handle the tax and the invoice. Your card details never touch my site.
