I fed 14 years of daily journals into Claude Code

So on Christmas, I did a small experiment and fed my Claude Code with 14 years of my journals. I was expecting some generic advice but was honestly surprised how great the insights were. I had something around 5,000 markdown files with my daily entries - mostly talking about random stuff, things that happened to me, and sometimes my brain dump over some heavier experiences. I never planned to read those journals (the process of writing itself is the goal), but then I realized - maybe Claude could find something interesting there. I started exploring a few perspectives and points of view (therapist, coach, relationships) and then I decided to process the whole 14 years (month by month, year by year) and create a final report on how I evolved over time. It was really deep and really heavy reading. Since I'm pretty critical of myself, my journals reflect that. Although AI echoed that narrative, I was able to partially steer it using a "strengths" perspective (what was good, what were my achievements, etc.). I'm still taking it with a grain of salt, but it quickly became one of my most useful self-development tools (monthly perspectives, brainstorming, thinking,...). AI is great at seeing patterns which I'm not able to see clearly or which I refuse to accept. It's not sugarcoating you and just saying things as they are (if you not prompt it differently). But of course it's still just echo chamber of your subjective reality. So I'm curious - I can't be the only one who came up with this idea: **1) Do you have any experience with feeding your journal into AI?** **2) How do you use it? How do you work with it?** If you're interested, here are some of the prompts I'm using: https://github.com/vystrcild/claude\_code\_journaling A few thoughts and examples of insights are on my blog. Before anyone asks: Yeah, I'm pretty aware how stupid it is to push all your personal info into an LLM, but I guess I'm more curious than smart.
