The Doodle Project

A Better Internet.

We keep families safer online, run IT for small businesses, and build open software people can trust. We are a small team in Frisco, Texas.

Or look at our software, from a free PDF editor to parish tools.

Our software

Software from The Doodle Project

We build tools we want to use, and we run them for people who do not want to run them.

Our flagship

TDPdf

Edit, redact and sign PDFs on Windows. Free.

Fix a typo, fill in a form, black out a name or get a contract signed. TDPdf does it without an account, without admin rights and without tracking.

  • Free and open source, for Windows 10 and 11
  • Redaction removes the text and images underneath, then checks the saved file
  • Send a document for signature, or sign it yourself
  • Inline text editing, forms, OCR, merge and split
  • One file to install, with silent install for IT teams

Our flagship

Antiphona

Parish software for Catholic parishes.

Families register, pay, sign up and stay in touch. Staff run faith formation, events, giving and more from one place.

  • Families register, pay and sign up in one place
  • Faith formation, OCIA, events, giving and payments for staff
  • Volunteer sign-up, forms, help requests and communications
  • Guides for staff and families on the docs site

Available

TDPdf Sign

Document signing behind TDPdf.

Our own copy of the open source Documenso signing service. Signed PDFs carry a trusted certificate and a timestamp, so they keep validating in Adobe Acrobat and other readers.

Available by invitation

Chores

A chore and points tracker for your household.

Kids check off chores, a parent approves, and points add up to a balance that buys rewards. It installs as an app on a phone or a school Chromebook. A parent invites each new household, and there is no billing.

Registration open

TDP Auctions

Auctions for non-profits and schools, at a fair price.

Timed and silent bidding, Buy Now, QR codes and text updates, in the phone browser with no app to install. You pay a flat fee plus card fees at cost, not a cut of what you raise.

In development

MassCast

Liturgical projection for Catholic parishes.

A parish loads its weekly worship aid, or writes the Mass in the tool. Volunteers move through the cues from any device, and wall-mounted boards show each cue. MassCast is not released yet. We are building it with parishes in mind, and we will say here when it opens.

How we work

Small on purpose

Private by default

We do not sell your data or use it for ourselves. Our auction system never reuses participant details, and TDPdf does not track you.

Open where we can be

We publish our forks and patches under the licences we received them with, so you can check our work.

Small and local

We are a small business in Frisco, Texas. The person who answers your email knows your setup.

Honest prices

Prices are on the page. Where a vendor charges us, we pass it along at cost and say so.
