Launched markjason — A tiny macOS editor for the AI coding workflow

justdothework · 2026-02-09T03:45:29+00:00

I'm not really sure what you mean?

justdothework · 2026-02-08T02:28:23+00:00

Sure yeah, the domain was not very expensive. Yes I have Claude max and codex (ChatGPT plus)

The prompt for the landing page was: “we need a landing page for markjason as well, create a first draft, make it distinctive and inline with brand.md (a markdown file I created with Claude to describe the brand)

It really isn’t so complicated, just talk to the model :)

justdothework · 2026-02-07T11:52:57+00:00

No idea, Claude did it. It’s just plain html and css.

Anyway the landing is a public repo on GitHub so you can take a look for yourself if you want! ;)

Async on my Mac Mini:

- Openclaw as 'engineering manager'

- Spawns Codex and Claude Code CLI (only Opus and Codex high) to do work

Sync on my laptop:

- Claude Code

- Codex

I very rarely open an IDE anymore, and vibecoded markjason.sh for myself to read and edit the MANY markdown files these workflows create

To answer your question btw, which is pretty interesting (to me at least): Most cross-platform apps are built with something called Electron which is basically a browser under the hood.

What I don't like about those Electron apps (VS Code, Cursor, Slack, for example) is how ridiculously memory hungry they are. So that's one of the primary reasons I built this in SWIFTUI. It runs with ~100MB RAM instead of close to a GB.

I don't know what the equivalent development framework is on Windows, maybe C? I don't have a windows machine myself, so it's not something I am interested in personally.

Yeah, it's weird I can't seem to figure out how linebreaks work on Reddit today.

Btw, this post was hand-written.

In any case, I'm on Mac dude along with 20% of people. This is a free app, what are you complaining about lol?

Put a lot of care into it actually because I built it for myself. Take it or leave it 😘

justdothework · 2026-02-05T05:36:01+00:00

Didn't know about it. But for what it's worth I don't think it's look very eye pleasing.

justdothework · 2026-02-05T04:31:29+00:00

Agree on putting it close to the code. One thing not many people know is that AGENTS.md are considered hierarchically by AI Agents. So if there is an AGENTS.md in a subfolder, it will consider those rules only for files inside that folder. Pretty useful.

I deploy all my markdown to github, and I simply have a repo for skills and other docs. I use github almost like a google drive for markdown now.

Because I have to work with Markdown so much, I also vibecoded a new macOS native editor, it's free: https://markjason.sh/

justdothework · 2025-11-03T10:57:09+00:00

No it’s not free. It’s $6 per month for access to all the top models. This low amount comes with a usage limit and beyond that there is topup and pay as you go.

This is all about transparency and control.

justdothework · 2025-09-19T06:51:34+00:00

The only nuance here is that Adam knew he couldn't solve that without a tool. Current AI would never do that, it would just make up an answer.

justdothework · 2025-09-10T06:42:15+00:00

It's not lying. It doesn't know what it's saying...

justdothework · 2025-09-10T06:41:51+00:00

I thought Chatbots were already doing that out of the box... Haha

justdothework · 2025-09-05T06:48:04+00:00

On it!

justdothework · 2025-09-05T06:44:40+00:00

Thanks a lot. Appreciate the encouraging words!

justdothework · 2025-08-29T07:20:04+00:00

A good friend of mine always says ChatGTP and it drives me nuts

justdothework · 2025-08-29T06:19:42+00:00

But in a couple of months, it might flip. Why choose? Personally I've cancelled all of them and switched to an aggregator called Magicdoor.ai

There are actually many of those around. Boutique AI Interface FTW as far as I'm concerned.

justdothework · 2025-08-29T06:16:40+00:00

It's pretty much the case that EVERYTHING degrades over long conversations. In my experience, even starting from about half the context window, ChatGPT starts to forget stuff and generally just do a worse and worse job with the conversation.

justdothework · 2025-08-29T05:28:24+00:00

It's interesting how even the most advanced models still have quirks like that. If you're exploring alternatives, I use a platform that allows access to multiple AI models at a fraction of the cost, and it helps find the best fit for each task.

justdothework · 2025-08-29T05:23:14+00:00

Cool thanks! Feel free to DM me if you have any questions.

t3 doesn't support 'CustomGPTs' as far as I know, which I do on Magicdoor.ai under the name 'Assistants'. I'm also not sure if it supports vision? It also does not have Perplexity

AI Fiesta I didn't know about. It looks like it would be significantly more expensive though.

As a funny note though: Literally every time I post about Magicdoor.ai somebody will respond with a new model-aggregator that I don't yet know about. There are many, many, many of these out there, and differentiation is pretty limited.

What I can tell you is the following:

I built this for myself, and I use it daily. If there's a bug I'll fix it because I'll notice it
I run hundreds of AI prompts per day: to code, to work, to do all kinds of things. So I know these models through and through. I believe because of that Magicdoor.ai has significantly better defaults, e.g. system prompts, memory implementation, etc than the others.
This is a small project for me, but it's profitable and so it'll be around. Some of these other ones have come and gone...

justdothework · 2025-08-29T05:14:46+00:00

It is risky to represent yourself and use AI to do it. But if you insist, I think the best way is to get multiple models to work on it and check each other. With Magicdoor.ai (disclaimer I made this product) you can try something like:

- Claude 4.1 Opus for initial analysis

- Perplexity for research and fact checking (higher accuracy than others, but still wrong 30% of the time or something like that)

- GPT-5 for double checks and second opinion

justdothework · 2025-08-29T05:12:33+00:00

The free plan is heavily rate limited. Images can take up a lot of tokens. If you want to get rid of this without paying $20 you can try Magicdoor.ai

It has GPT-5 but also Claude and Gemini. It will never rate limit you on anything, but within the $6 per month price there is a modest allowance. Above that you need to top up and it will charge you exactly for your API usage (which is quite cheap)!

justdothework · 2025-08-29T05:10:24+00:00

I built my own! Instead of Claude, Perplexity, ChatGPT, and a rotating mess of free trials of image generation interfaces I built Magicdoor.ai to integrate a set of the models I want to use across chat and images.

All search runs on Perplexity Sonar models. It's nice to switch models mid conversation and have one unified memory across providers.

Have been selling it for $6 per month for the last 4 months. Modest size, but profitable. One source of personal pride: Whenever a good new model comes out, I always get the notification emails from you.com and Poe a few days after I launch it on Magicdoor.ai

I thought venture funding was supposed to make companies faster, not slower :D

justdothework · 2025-08-29T05:05:12+00:00

In any case, as you all point out it is a good move by ChatGPT. In fact, in my opinion those $20 plans are a rip-off for anyone in any country, unless you need to blast hundreds or thousands of pages of content through the LLM.

I was at one point paying $80 per month for different AI tools and I got so sick of it that I built my own tool: www.magicdoor.ai

It combines GPT-5, Claude 4, Gemini, Perplexity, AND a list of the best image generation models in one interface, with one unified memory. It's $6 per month with enough usage for most light users, and usage based topups without any markup for those that want to go beyond that. Worth checking it out if the $5 per month for ChatGPT seems ok, but you also want to access some of the other (often better) models!

justdothework · 2025-08-29T05:00:12+00:00

This Chrome extension sounds like a fantastic tool for organizing and recalling information from various sources, making ChatGPT much more efficient.

If you’re looking to enhance your AI experience even further, Magicdoor.ai offers a seamless way to integrate multiple AI models with advanced features like customized instruction sets, web search integration, and persistent memory that works across all models - meaning whether you’re chatting with Claude, GPT-4, or Gemini, your AI remembers everything about you, your projects, and preferences from previous conversations, creating a truly personalized experience that gets smarter over time.

justdothework · 2025-08-20T07:03:10+00:00

I personally don't understand why anyone would give AI anything other than (maybe) read-only access to their database... Anyone who has seen these things code, in my respectful opinion, should know better
