Who Writes Typewire’s Code? People.

Last updated: November 6, 2026

AI-generated code is prohibited anywhere in the Typewire application codebase. All of it is written by human developers, who also review, test, and maintain it.

On October 30, we published this as a formal policy. You can read the full AI and Human Engineering Policy

Why we work this way

Your email provider’s code handles your messages, your encryption, and your account. We think the people who build that should understand it, be able to explain every decision in it, and be accountable for it. When a person wrote the code, there’s always someone who can say why it exists and what it depends on.

It also fits how the rest of Typewire is built. We develop our software in-house, run it on our own servers in Vancouver, and don’t send your data to third-party or big tech services.

What the policy covers

The prohibition applies to the whole application: frontend and backend code, databases, authentication, encryption, infrastructure configuration, and tests.

It doesn’t cover everything we do. The policy allows AI for non-code work, such as research and general productivity, as long as it never compromises customer privacy or confidential information.

Human-written code isn’t automatically secure either. People make mistakes, which is why testing, review, and ongoing security maintenance still matter. The policy is about accountability, not a promise of perfection.

Where we stand

Companies across the software industry are making different choices about how they use AI, and that’s their call. This is ours: the code that runs Typewire is written by people, and the policy is public so you can read it, question it, and hold us to it.

It also reflects a commitment to keeping skilled people at the center of how we build.
