How I use audio journaling and AI to improve my trading decisions

I have been using a Google Form with a single prompt to journal since 2016

I go for long walks at night a few times a week and find myself journaling a lot then. It got annoying to stop my walk to type out a thought so much, eventually I started primarily voice typing instead.

But I still had to stop and pull up the Google form, then start voice typing, fix any mistakes, and then continue the walk. So I moved on to just turning on a recording app on during the walks and just start talking whenever I want without having to stop or pull out my phone.

I transcribe the audio file when I get home and add it with a summary to the journal.

Now I keep a livestream going while I'm working at my PC and transcribe and summarize whatever happens there too.

Tracking stock trades is one of the most advanced uses of audio journaling I've seen– wow! You're pushing that into an area I had not thought of, very cool.

I made Stardate[0] for my own voice journaling and use it similarly. I track how much my dog weighs, sailing hours and notes, and new issues I find in the app. Recently I used it to make a daily checklist on paper by feeding the notes into LaTeX[1]. There's just so much to explore here!

I posted this before but I think I have a better system for audio journaling.

TL;DR use Apple shortcuts to transcribe my recording using OpenAI whisper model and add it as an entry to Notion.

The key difference is that there's close to zero manual intervention. I have all the logs in Notion and I have another shortcut to query these journal entries again using ChatGPT in Apple shortcuts.

i highly recommend this approach. Especially for kids learning to write and keep a diary habit. I wrote about this in 2021 in Chinese https://blog.est.im/202105/stderr-004

This sounds interesting! I find journaling very tedious but I think is my ADHD brain that doesn’t wanna do anything too annoying. I’m not sure how from audio journaling Id get stats like MAE and MFE, apart from general win ratio and accuracy percentage… but I’m sure different stuff works for different people

I've been thinking of using a voice + AI flow. I do a lot of thinking when I go on walks and it'd be nice to record, transcribe, and summarize in a single flow. Does anyone know of an app that does all three?

Cool, now post a journal of your net returns versus the S&P.

Surprised this didn't end with a soft sell on an e-book course.
