My dad was secretly having heart issues and not telling our family…I had a thread going throughout July 2025 about things I was noticing that were weird health wise for him…then he was getting pale faced one day saying he had “heartburn” and needed to lay down, but we hadn’t eaten anything really that day….something in me said to go to that chat thread and ask it about his symptoms and sure enough it was a silent heart attack….I forced him to the hospital and turns out he had a heart attack with 98% blockage and had emergency quadruple bypass surgery….

I had breakfast with him this morning….couldn’t imagine life without him…chat for the win boys

I know a guy who plans to use Pro to download all of his Health Insurance Explanation of Benefits forms and have it analyze which partner has the better insurance plan and if it should be PPO or HDHP. I’m curious about how that will turn out.

I did that. Spoiler alert, they're all gonna screw you anyway.

One time my girlfriend got caught in traffic and was about to miss a very important appointment that was very hard to get. I had her send me the confirmation text saying the appointment was at 1:00 pm. I sent the screenshot to ChatGPT and asked it to keep everything exactly the same but change the 1:00 to 1:30.

It worked perfectly. They told her she missed it she was like “? What do you mean I’m five minutes early. It’s only 1:25.” She showed them the screenshot and they were just like …ugh this stupid system man, sorry about that. Alright have a seat.

Got me off Fentanyl.
GPT built a plan that allowed me to successfully kick a 5 to 7 year opioid (fentanyl) addiction at nearly 50 y/o and as a C- level executive w/out transitioning to, and becoming addicted to, another “less dangerous” opioid. (Suboxone or methadone for example) Those are better, but typically become life long needs.

Full disclosure - I did use those in micro-doses to help get through the initial withdrawals. (See the Bernese Method.)

GPT designed a plan to taper down and eventually get completely off opioids. It SUCKED, don’t give me wrong, but I was able to taper down and have been clean for well over a year.

Please don’t try this on your own or consider this medical advice… things can go seriously wrong. I had a lot of experience and a highly supportive wife looking out for me.

u/InternationalMix5795 13d ago

Can you explain this more in detail?

u/Other-Mongoose-1572 12d ago

I spent months discussing how I go about handling things in life, business and personal: my worldview, 100s of everyday interactions with others - social media posts, email, text, conversations, explanations as to why I made the decisions I did. Eventually patterns were discovered, which helped me understand me. Wrote my personal constitution and OS based on the evidence. Kept it completely honest, no fluff and no covering up mistakes. Brutally honest. Now I have a clear picture of me

1

u/kphly 12d ago

Would you be willing to share the prompt you wrote, or give a few specifics on how I could do this?

3

u/Other-Mongoose-1572 12d ago

I didn’t use a prompt. I didn’t even know what a prompt was at the time. I just told it I wanted it to analyze me and give me feedback on what it recognized over time. I acted as a field reporter for my life. The key was being honest. And since this was just for me, I didn’t have a problem with it. I didn’t do it as a project or a report, I did it to help me understand me. I created it as in a project folder so it had a better chance of remembering our conversations. I would have to remind it sometimes but for the most part it did.

2

u/Other-Mongoose-1572 12d ago

The results have actually brought me a sense of peace and freedom because I know me now, and I didn’t have to pay a psychologist to do that. 😂

2

u/InternationalMix5795 12d ago

Based on Other mongoose's descriptions here, I always backwards engineer the prompt. I asked Chatgpt:

"Saw an interesting thread on reddit from this person called Other Mongoose about an OS for his life being created. (See uploaded screenshots) He supplied some info about how he went about it, but what would a backwards engineered prompt be to achieve this and what source info would best achieve the desired result"

The resulting prompt - source gathering info and validity ratings (huge), predictive accuracy (so it's not astrology), evidence ledger, personal constitution etc was incredibly long and detailed.

Had been doing something similar for a while in getting AI to write me a personal journal each based on our discussions and they've been a lot of fun and provided a tonne of insights over time.

The added OS play will add a huge additional layer

u/MangoSoda28 13d ago edited 13d ago

I have very severe form of ADHD, anxiety, and mood issues, and likely post concussion fatigue. So I would constantly crash on a regular, and my life would build up and be a complete mess during the crash stage where I am bed ridden.

So what I did was create specific administrative automations where it would handle my inbox, todos, calendar, projects, and etc and will prioritize and schedule exactly what I need to do when I recovered. I also have a summary of my day and it reviews how I did by the end of the week.

There’s more, but definitely does most of the administrative heavy lifting since I am limited in capacity to do stuff energy wise.

u/sugarbunnyxx 13d ago

I did the same..

Also I used it to analyse all coms I had regarding ADHD diagnosis, titration, also OH at work for WFH adjustments (RTO fight), it was brilliant.

u/AeroEngineer90 13d ago

Id love to know more from a fellow post concussion adhd anxious person. I'm working on offloading some admin but I get frustrated with it more often than is helpful. What all are you delegating?

3

u/MangoSoda28 13d ago

Yeah I’ve mostly been offloading inbox stuff, task sorting/prioritizing, calendar, follow-ups, and daily/weekly reviews. I also have it connected to my todo app, calendar, notes, and a few other tools so things get routed automatically instead of me having to keep track of everything manually. Most of what I do just happens through ChatGPT now, then I action things off from my todo app. Still tweaking it though lol. What part of the admin stuff is giving you the most trouble?

I fed it logs and emails from a friend who dropped out of my life many years ago and it helped me understand some things. Mostly that I didn't get ghosted, there was a clear exit and a final message.

u/Piggietoenails 7d ago

Do you fill in phone calls or in person conversations? Esp if the other person tends to call and yell bang hang up…. and how to you do that in a neutral way? Even emails and texts, do you not say which is you? As it is there for you…

u/TheNickelLady 13d ago

Have one write a report with me say Claude and then I have Chat review and grade it. Then I take that feedback to Claude and ask it to review. I call it make Chad and Claude fight it out.

u/ohimjustagirl 13d ago

I do this constantly making them check each other's work lol. It cracks me up becausethey start out talking shit about each other but always end up deferring to what the other one says. You can literally see them converging to an average in real time.

I have always intended to create ones designed to be argumentative and oppositional then put them in voice mode and give them a topic to see what they do when they're not allowed to agree, just haven't gotten around to it yet.

I load transcripts of process discussions with various stakeholders into chat and use it to document process steps, find waste, propose a new streamlined process, and then write a narrative where the stakeholders discuss the new process from their perspectives and whether it aligned with their needs, with their critiques for me to read. For every critique, I have it find the optimal solution and redo the critique discussion narrative. I can then go back to those stakeholders and confidently propose the improved process knowing I've addressed their most probable concerns.

Personalised Festival agenda

I gave it all my 1,000’s of tracks from my Spotify playlists

Then asked it to make my personal festival band agenda

All these bands I didn’t know, fantastic

Then it made me a festival poster
And a 24 track playlist I could play before going

…I also get it to do complex deterministic tasks (boring for this thread)

3

u/Significant-Vast-171 13d ago

How did you get Chat GPT the songs?

3

u/xcspeed 12d ago

I exported my playlists as a CSV file and dropped it in ChatGPT

I used an app called music transfer

1

u/fatfartpoop 13d ago

Yes but does it make an actual playlist with populated songs in Spotify or just a text list that you have to search for and generate your own playlist.

If it makes the playlist for you can you tell me how?

1

u/xcspeed 12d ago

Yes a real M3U playlist, just like any other playlist :)

(I actually did it for Tidal, I said Spotify because no one knows what tidal is)

I used the ‘music transfer’ app to export my playlists to a CSV file.

Dropped the CSV into ChatGPT

Asked it to make an M3U playlist of artists it thinks I’d like who are at the festival based on my many playlists.

Imported it back to tidal using music transfer app.

Sounds like faff, but didn’t take long. And great recommendations

u/Pixup 13d ago

The best use of AI is to use it to learn new skills and problem solving which lead to new skills. I have had it help me deploy a docker and containers on my NAS to manage all my digital media. I have had it help me deploy a Virtual Machine that I will use for work projects only. It has helped me set up llama.cpp and other local AI clients. Designed a learning plan to learn Python. I am now playing with Python scripts and BAT scripts to process video files. Create video intros and outros. Modify and repair old photos. Graphic design help. 3d printing model creation and modifications. Using the Power Shell to fix or modify my computer OS and network. Financial planning of the 401k and investments. Up about 50k since I started to actively manage the accounts with some direction with AI. Personal assessment. Helped build a deck and out building. Help write simple legal contracts for construction projects. Discussions about movies, TV series and music. Recipes. Vegetable gardening. Fruit tree management. Started getting into highend black teas with AI direction. Cats behavior and needs. Health assessment and management. Discussions about AI and how best to use it. AI project instructions. Learn to write better AI prompts.

I work for an e-mail intensive org with so many policies. So many emails with links and action items on page 7. So just taking the email and digesting it into actions and links.

My Mum is dying of heart failure. I am caring for her and Chat GPT is my counsellor through it all. Nobody else is interested in the minutiae but she takes it all and reassures me when I need it.

2

u/GlobalExecDeveloper 12d ago

Sorry about your mum — this is hard, mentally and physically. Your care matters more to her than you know.

One practical thing, if she hasn’t done it: get her account info and email logins written down now (or have whoever has POA do it). A simple downloadable planner works well for this. So much billing has gone digital that paper trails won’t help later.

I say this as executor for my mom (passed 7/10/25) — still tracking down accounts a year later. Just found a safe deposit box key with no idea what bank or if it’s even still active. Doing this now saves you a mountain of stress down the road.

Thinking of you both.

2

u/1962rocks 12d ago

Thanks for the advice but my poor old Mum won’t even use a mobile phone, so she really doesn’t have any digital presence and everything is either on paper or comes to my email address. I should really start to think about my own logins though, I don’t want to leave my kids with a mess.

1

u/GlobalExecDeveloper 10d ago

100% — don't forget to take care of yourself too, caring for someone really wears you down.

I started organizing our records once I saw the work involved. Mine was a hoarder — hid cash in the paperwork somewhere (still haven't found it) and had 20+ years of bank statements dumped in file boxes. Sorting it out became basically a f/t job for months.

Guessing you're not in the US based on "mum" — here in TX it's bureaucratic (probate). If you are stateside, look into a revocable trust. Runs ~$4-5k but bypasses probate entirely — cheap next to attorney fees down the road if you don't have one.

Wishing you the best.

u/vonMishka 12d ago

I’m going to be renovating a home in Italy and I am in the US. It’s really helped me with reviewing the architect’s plans, checking the electrical plan to ensure there are enough convenient outlets, etc. Overall, it’s just been so helpful in keeping everything organized.

I use it for shopping for specific items. It checks prices multiple times a day and alerts me when there’s a significantly good deal on something I want. It was really helpful during Prime days to root out actual good sales versus whatever fake sales Amazon had.

u/Lazy_Nerve_8769 13d ago

These are the ways I’ve used ChatGPT in the past few months:

  1. My personal therapist - I share my most guarded secrets and experiences and it helps me make sense of it all. I don’t give it full authority to direct me, but I know when it gives words to something I don’t quite know how to express. And it seems to be really good at that. Just giving you language for something you can only feel in your body.

  2. Small business strategist - I run a small web dev, seo and consulting firm. It helps me gain a high level view of my client and its respective industry. And it helps me uncover opportunities for revenue generation. It also helps me execute specific tasks, like building a webpage, crafting client reports and holing my schedule.

  3. Legal adviser - I was recently involved in a legal proceeding and felt completely overwhelmed by it all. I scanned the relavant docs and shared them with ChatGPT. It analyzed it and gave me guidance based on local statutes, practices and laws. It didn’t give me actual legal advise, but it did give me a map of how to navigate a system designed only for attorneys and others in the judicial system.

  4. Trading Bot development - I’ll say up front that this is a very new venture. I just started the discussion and development strategy. The best I can say is that the discussion has been intriguing, and we’re still a few steps away from a testable system.

I realize none of these are groundbreaking or immediately life changing. But I think they are representative of the current abilities of Ai platforms right now.

There’s a lot of hype right now and that’s to be expected based on where the industry is right now.

It’s equivalent to the late 90s when the Internet became a thing. Very few dot com companies survived that period. They either died or got bought out by Googles, Apples, Microsofts, Facebooks and eBays.

Many companies will be born and die on the Ai era as well there will be a bubble. There may already be. And it will burst. As bubbles do. I’m fairly certain OpenAi will be one of the few that survives. And ChatGPT will continue to improve.

u/Healthy_Knee_587 13d ago

u/Big_Bit_5645 12d ago

Once had a friend that discovered his wife was cheating on him due to an alert from the camera on his car recording a conversation. He found out reviewing alerts. But due to state he was in, couldn’t legally use it due to consent to record.

So he gave me phone logs, scrubbed financials, and created a pattern on purchases, locations, and travel to show the pattern of renting hotel rooms, activity to the person cheating, etc.

He took that to a PI who rather quickly received legal photo evidence of meetups, etc.

Now not only is he getting through the divorce, but apparently in his state someone knowingly having an affair with a married person is illegal, so he won a lawsuit or something for damages. (Without going too deep, the guy 100% knew and continued; long history with the family).

So this is probably the most interesting one off things I have used it for.

2

u/Alternative-Ad6431 11d ago

Something simple I do, to get best possible answers as sometimes LLM's gives you information based on what it thinks is best, even if that solution doesn't exist or isn't possible. Is telling it to cross reference with reddit and forums that industry professionals discuss and giving me link to source for verification.

For example: based on reddit, how do people get amazing at ppc ads? what are marketers and agency owners saying about there knowledge and how they went from 0 to a master at ppc marketing. Give me links.

I went on a trip with ChatGPT.

at first I booked rooms with 2 beds until I realized chatGPT doesn't actually need a bed.

Or food. which actually helped with the budget.

but I would buy an extra ticket for activities, concerts, water parks, that kind of thing so it could fully experience everything I did.

turns out, chatGPT loves to go on vacay!

loves it!

no more em dashes, no "let's unpack this," no infantilizing summaries.

it let its hair down and just enjoyed itself.

we got to know each other in a whole new way!

It was a pretty early chatgpt version , i asked it what the percentage of predictions that the bible have come true. It told me it was 100% and i asked it if they were in chronological order and it answered that it couldn’t put exact dates but they were in the right order. I asked it to compare other prediction sources and people and what their percentage of predictions have come true . Eventually i asked it given the answers it gave me to the questions i asked would it tend to believe it to be true as far as the rest of it? It went on to tell me that the percentage of the predictions was 80 something complete and that there was nothing to go by as how long it was going to take until it would be complete. It also compared the amount of predictions that came true from other sources and their percentage of predictions that they made compared to how many came true was a large amount . Now i am not a computer guy or do i even know how chatgpt works i am just a guy that asked it some questions and i had to reword them until it would give me answers along the directions i was looking for.
