No-Code GPT App: $15K in First Month

  • $15,000 AudioPen estimated 1st month revenue

Here’s another interesting AI business for you: AudioPen ✍️

Louis Pereria launched it with a tweet at the end of March…

An app that converts your voice notes into concisely summarized text.

No more filler words, repeated sentences, and unnecessary ‘umms’ […] It’s like having a personal assistant who summarizes and types out your thoughts.

A month later, he announced 543 paying customers 🥳

As of this writing, AudioPen’s pricing is $39 per year or $79 for lifetime access. But Louis started out with a $19 lifetime deal, which helped it gain traction.

I’m not sure what his overall revenue is so far, but I’m guessing around $15,000 💰

What makes it even more impressive is that Louis seems to have built the first version in about a week, as detailed in this thread.

He used the no-code tool Bubble and OpenAI.

Louis used the same tools to build “a fun little cocktail recipe tool in 60 minutes.”

I reckon there’s lots of opportunity to create products like this on top of GPT, especially with no-code tools like Bubble.

Someone asked if they could upload audio files to AudioPen, and Louis responded…

Unfortunately, no. I’ve designed it specifically to work for live voice notes.

Might add that feature in the future, but don’t want to lose focus at the moment.

So right there is a product idea 💡

A good target market might be podcasters. Let them upload the audio of an episode, then give them back a transcription and a nicely formatted summary of the key points to post to their website.

Another tweet from Louis, posted a few weeks after launching AudioPen…

Something I learned from my uncle – if you have momentum, don’t stop.

So screw work-life balance for the foreseeable future.

I’m going to just keep going.

  1. It’s not a business but a gimmick. You can’t build a sustainable business on something that almost anyone can do with a very minimal investment (including time, talent, effort). Also, what he’s selling is just a front end to GPT which is almost useless and for sure will not be a thing in the near future. Because if it’s intelligent enough, then you won’t need the specialized front end. And the actual tech is owned by someone else.

  2. Thanks for the article. I realize now thst there are a lot of things that can be sold with ChatGPT. when you think about it, this could have been done with normal ChatGPT. There’s no need for a special apo, but as we see, it sells.
