Free tools · by AVR Builds

Free web tools you can actually use.

Small, focused tools we've built for the work we do — like preparing talks and sending personalised emails. Made with the same care as our client work, given away free. They run in your browser or through your own accounts, so nothing you type is stored on our servers.

The tools

Free to use, nothing to sign up for. Open one and go.

Talks
Sermon & talk preparation

Write a talk block by block, drop in Bible verses, and present it fullscreen from your phone. Everything saves on your device — no account, no sign-up.

How these work

No accounts to make with us, no catch.

01
Open it
Tap a tool and it loads in your browser. Nothing to download, no sign-up, works on your phone.
02
Use it freely
Everything runs on your device or through your own accounts. Your work stays yours — we never see it.
03
Keep it handy
Add it to your home screen and it behaves like an app — some even work with no connection at all.

Found these useful?

They're free and always will be. If one saved you some time, you can buy us a coffee — it helps us keep building and sharing them.
