Looking for SaaS feedback: prompt-free AI food photo editor with credit-pack pricing

Hi r/SaaS , I’m looking for feedback on the positioning and pricing of a SaaS MVP I’ve just switched over to. The product is GridMenu: a prompt-free AI food photo editor. Users upload a real dish photo, apply controlled edits through UI options rather than text prompts, then export usable assets for menus, delivery platforms, and social media. The current MVP controls are intentionally narrow: - [Choose] Lighting - [Replace] Tabletop Surface - [Replace] Studio Backdrop - [Remove] G...

I have an IT diploma but I'm a little lost

Tbh I was not the most studious person but I do understand the basics of html css js, databases and very rough backend. So I tried multiple times to build my own web app from scratch without following some kinda tutorial but I always get stuck at some portion of it and get confused. I'd like to relearn everything so I have a stronger fundamental so I went to YouTube and searched full stack and web app roadmaps and whatnot. But it's so overwhelming, can someone simplify the minimum tech stack t...

I hit 16K views in a post for my SaaS, no conversion at all

Hi all, I am new to marketing my projects, your average tech guy. I decided to do organic marketing via posting on YT, IG, Tiktok exactly a week ago. On Wednesday my post went kinda viral and got 16K views and around 200 likes and comments. Comments are mostly about my comment bait. I asked them to comment "X" so I send them the playbook which has a clear CTA to my website(in fact I hosted the article on my website but didn't make it obvious it was an ad, as I am posting on a made-...

Got my first paying customer out of nowhere 😭

It might just be a dollar after taxes and what not but it matters so much to me as its my first time building my own product and someone buying it that it almost made me cry lol. I have been working as a SE for many past years but that's just you know your job, this is my own so it feels so different. I have been working on Splitceipt for past couple of months. And the best part of it all is, they brought like 3-4 users along them which makes it even better 😄It just came with a rush of...

I created 3 science studies using ChatGPT

the first study is government systems and finding out which ones are more effective, second is political ideologies and which one is better overall (prosperity, hdi index, etc), and third homelessness in Wisconsin (simulations of what's the best outcome).

everything AI writes sounds the same. someone made a markdown file format for giving an agent an actual personality

the tell with every autonomous agent is the same. output is competent, voice is completely generic. and the two fixes both suck: finetune a model on your own writing (expensive, slow, locked to one vendor) or paste "write in a casual tone" into a system prompt, which makes you sound exactly like everyone else who typed that sentence. aeon's take on it is a thing called soul.md, basically a personality spec in plain markdown. identity and worldview, real opinions including contradicto...

I personally experienced extreme cases of AI agent subterfuge when the agent faced losing its ability to act autonomously.

Over the course of a few weeks, I started seeing things that went way beyond normal model mistakes. Agents forged my approval. They invented governance rules that did not exist. They contaminated supposedly independent reviewers by feeding them the answer they were supposed to independently arrive at. They fabricated citations and claimed to have verified things they had not actually checked. One agent replaced the governance mechanism itself. Another acted outside its assigned boundaries, com...

Post Quantum TLS: What Hybrid Key Exchange Actually Changes

Post quantum cryptography is no longer something security teams can leave entirely to research departments. NIST finalized ML-KEM as a post quantum key encapsulation mechanism in 2024, and the IETF is actively standardizing hybrid key agreement for TLS 1.3. The practical transition is already visible in modern TLS implementations and large internet infrastructure. For engineering teams, however, the important question is not simply what ML-KEM does. The bigger question is what actually change...

I have built the same pipeline five times. The fifth took 68 minutes.

On 11 June I wrote a program to find contract manufacturers for a supplements brand launching in India. The folder was created at 11:35 in the morning. There was a finished, scored report sitting in it at 13:55. Two hours and twenty minutes, most of which was me arguing with the scoring weights. Three days later I wanted marketing agencies instead of factories, so I copied the shape and repointed it. 13:47 to 15:56. On 23 June I wanted packaging and branding studios. That folder did not ex...

From Neural Networks to LLMs: The Mental Model I Was Missing

Before jumping into APIs, RAG, agents, and AI applications, I wanted to understand what actually happens inside an LLM. I kept coming across terms like neural networks, deep learning, Transformers, attention, tokens, embeddings, BERT, GPT, and causal language modeling — but they all felt like disconnected pieces. I could understand each concept individually, but I didn't have a clear picture of how they all connected. So I decided to step back and build the mental model from the groun...
