Pterocos - HTML Online Editor with AI chat Im looking for feedbacks! and people interested to work with me note it's non-profit

Hi Indie Hackers,

I'm building SpendLens — a free AI spend audit tool for startups (tells you where you're overspending on Cursor, Claude, ChatGPT, etc.).

Looking for 3 quick conversations (10-15 min) with founders or engineering leaders who manage AI tool budgets.

If you're interested: what's your biggest frustration with your current AI tool costs?

Comment below or DM me. Happy to help with your projects too.

The "no signup, save to localStorage" choice is doing a lot of heavy lifting here — that's the difference between people trying it and people closing the tab. Two genuine questions: (1) how are you handling the AI chat cost when there's no account to rate-limit against, and (2) have you thought about a "share this snippet" deep link as the primary growth loop instead of the Discord/Trustpilot route? Feels like the product has a viral mechanic built in that you might be under-using.

(I'm shipping something adjacent on May 28 — a sensemaking/AI productivity tool — so I'm lurking in this corner of IH to learn from folks like you before then.)

curious what kinds of AI requests actually land here. does it see the live preview or just the raw code? that gap matters a lot for what you can delegate to it

Hi, I got this error from the AI assistant:

Try again! [debug: Cohere(command-r) HTTP 404 — {

"id":"c350c20f-e699-4d87-a41b-a4a611f4c521",

"message":"model 'command-r' was removed on September 15, 2025. See for a list of models you can use instead."

}]

It looks like the backend is still trying to call Cohere's deprecated command-r model, which now returns HTTP 404.

The AI panel also became unusable afterwards.

"I’m working on an interactive agent too, but the editor you made is so much better and really fascinating! The concept of a zero-signup, client-side editor with local storage is good

This is a great

Love the non-profit framing. Honest question - how are you thinking about keeping volunteer momentum past month 1d that's usually where these stall, not the tech

I saw that you have a lot of badges, are they bost your DA of your site?

Love the concept of a zero-signup, client-side editor with local storage. For a browser-based setup handling heavy AI chat streams, your biggest hurdles will likely be smooth real-time token rendering and front-end state management so the editor doesn't lag during long sessions.

I’m a technical founder and built a live marketplace platform (ASCANx) solo. I have solid experience managing complex relational data layers and third-party API pipelines.

I'd be down to jump into the GitHub repo, test out your AI orchestration logic, and help you optimize some of the client-side architecture or backend integrations.

I had to send out my review also. They are indeed recommendable.

i tested here and looks fine!

what's the wedge vs codepen/jsfiddle? curious how the inline AI compares to just pasting into chatgpt - faster iteration loop maybe?

"Does this online editor support mobile responsiveness, or is it expected to be used on a PC?

Unless it's meant entirely for PC, please allow me to offer a quick suggestion. When I used the editor on my iPhone, I thought it might be a bit easier to navigate if we could switch between files using tabs to get a clear view of each one, instead of having them listed vertically."

"I’m working on an interactive agent too, but the editor you made is so much better and really fascinating!

Saying that it's the best tool for learning how to code using AI chat (for both assisting and building), combined with having HTML, CSS, and JavaScript ready to go, makes it an excellent, top-tier content for beginners."

the 'AI for free' + non-profit angle is interesting - what's the sustainability model/ open-source LLMs or planning a paid tier later/
