Custom GPTs are free for everyone as of yesterday, so I thought I’d post some of the best ones I’ve made over the last few months for all of you:

Proofreader (https://chatgpt.com/g/g-hjaNCJ8PU-proofreader): This one is super simple. Give it what you’ve written and it will provide no-BS proofreads. It’s not going to hallucinate content, just point out mistakes and parts that don’t make sense.

Make Real (https://chatgpt.com/g/g-Hw8qvqqey-make-real): This makes your napkin drawings into working websites. It’s got some of the same limitations other code-generating AI tools do, but it does a surprisingly good job creating simple working web frontends for your ideas!

I made “Postman for PMs,” a tool to help non-engineers understand and use APIs!

The Answering Machine is a proof-of-concept system that I built using pre-LLM natural language processing (NLP), specifically NLTK, to produce answers to questions asked about data in plain English.

Looking back, this project was a great insight into what LLMs immediately allowed that was incredibly difficult before. This project was several months of work that the openAI sdk would probably have allowed in a few weeks - and that few weeks would have been mostly frontend design and a bit of prompting.

Editor’s note from 2025:

First Ten is no longer available after Google discontinued custom voice apps in 2023, but I’m leaving this article here as a record. Now, similar apps can be built in hours or minutes using modern AI models. First Ten used a now outdated intent routing system to fetch information from a serverless architecture about the Bill of Rights. Interestingly, my infrastructure for this app is still up and running behind the scenes because it’s truly serverless and costs nothing to host.

First Ten is an educational app containing information about the U.S. Bill of Rights, accessible on Google devices and smart speakers.
