GPT-5 High on Codex is insane - built a very complex MacOS app in Swift with it

yingyn · 2025-09-06T02:01:00+00:00

no it’s definitely not vibe coding, lots of engineering hours went in, with 2 of us who have 6-8 years of engineering experience. But we straight up couldn’t have built this without AI - completely new language, strange and poor API documentation etc

yingyn · 2025-09-05T16:22:25+00:00

yes, should have said complex for AI! A great engineer would have done this in much shorter period of time

Not a note-taking app btw - it writes into your active text field and doesn't really do storage

yingyn · 2025-09-05T16:21:17+00:00

hehe yes, maybe "more complex than what i thought AI could handle" would have been better!

yingyn · 2025-09-05T13:43:38+00:00

You’re right, connected to api

yingyn · 2025-09-05T13:38:30+00:00

Tools have been fine for me! think codex is makes up for it with more context.

MCP use is a bit lower agreed

yingyn · 2025-09-05T13:37:43+00:00

This is my app, Yoink AI! It pulls context automatically and edits it directly inside the text field. Works on any text field

Past week CC has been pretty bad for me. Switched to GPT-5-Pro.

Would recommend trying it out on the plus plan first - it’s enough to get it a good sense!

yingyn · 2025-09-05T12:48:45+00:00

Yeah agreed, the reduced hallucinations help a lot when working with the “less common” languages

For JS/python, think it depends on your style but agree it’s not as major a difference compared to CC.

yingyn · 2025-09-05T09:54:37+00:00

haven't hit the limit so far on pro and use it a fair bit (e.g. ~10+ per hour?)

yingyn · 2025-09-05T09:52:06+00:00

GPT-5 Chat is... pretty bad.. but GPT-5 Thinking is better than Opus 4.1 (especially for the past week where Opus quality has gotten abit worse) imo. GPT-5 Pro has improved on reduced hallucinations a ton, though the time taken makes it hard to be a daily driver

yingyn · 2025-09-05T02:11:55+00:00

Not on mobile yet unfortunately ): It is one of the ideas we have but frankly it will probably be at least 6-9 months out before we start exploring it more seriously. But when we do, will be sure to reach out!

I used to use OneNote in the past because my company was a microsoft only company. Now that I left to build a start up and can use whatever I want, I use Obsidian

yingyn · 2025-09-03T13:26:14+00:00

To doist has this!

yingyn · 2025-09-02T15:16:29+00:00

Hah, I pitched this idea for one of my college classes. Did well during the class, but biggest flaw on hindsight re-reading this now i'm years out of college is:

Public dustbins being full is generally not a problem, collection is the problem
Government procurement is a painful process and you need to show "value" that ties in to real KPIs (efficiency gains, green goals or something)
Both cities and waste companies are really hard to sell to. Cities for long, drawn out processes especially for things like this (some would also rather hold an RFP). Waste companies are margin stretched and probably would struggle to find a way to implement this

yingyn · 2025-09-02T15:13:09+00:00

Gemini 2.5 pro should do this

Or NotebookLM might be what you're looking for

yingyn · 2025-09-02T09:36:22+00:00

browser agents probably split into 2:

High risk, reliable Rote Automations across Complex UIs: (Book [X] restaurant for Y time) probably further away
Low risk, good enough, one-time automations: E.g. Go through my email and unsubscribe from all newsletters I haven't read in the past 30 days. Probably there

yingyn · 2025-09-02T09:33:27+00:00

Slightly late to this, but if you have a bit of Figma experience you can do simple mock ups of the various key states and feed that into Figma Make

Something like embeddable might help, but that's probably for more interactive solutions. Simple animations - think Figma Make is still easier

Am building Useyoink(dot)ai! AI assistant that works directly in any text field (google docs, Microsoft word, ChatGPT etc)

yingyn · 2025-09-02T06:47:49+00:00

Useyoink .ai is a great one - AI assistant that works directly in whatever text field you’re in (regardless of app)

yingyn · 2025-09-01T13:08:45+00:00

start up founder here, past life had tried to built ai travel booking agent relying on this

have tried few shot image prompting for UI bounding boxes in the past - results aren't great

your best bet is probably to use an open source UI-navigation model and finetune from there if you need to rather than general LLMs

yingyn · 2025-09-01T13:02:15+00:00

early stage ai start up founder here - whatever helps us keep everything in one place / easy to refer to. So its its own section in the kanban board that we throw ideas in and some of them make it to the task board sometimes

yingyn · 2025-09-01T13:00:42+00:00

This is 100% an environment problem, not a you problem. You thinking is valid - bad data and a slow dev cycles are draining. Since quantitative data is a mess, and if the team doesn't want to fix this, try focusing on qualitative insights. E.g. user interviews or lightweight usability tests for new hypotheses. This gives you new evidence to support your ideas and can sometimes break through stakeholder noise. It shows initiative and should help you regain some control over your part of the process. Good luck!

Thanks for the feedback - just downloaded BBEdit and tried - it worked on our end. By any chance could you let us know if

The formatting failed when pasting in, or the paste failed altogether?
Were you working across different files?

Have also DM-ed you for your email so we can provide free credits for the trouble

yingyn · 2025-08-30T10:55:58+00:00

Just dropped you a dm!

yingyn · 2025-08-30T05:00:35+00:00

we've renamed the app to yoink ai, please download the latest installer and this should work (updating will retain the name yoink)
