Canva - I used it for simple designs but ChatGPT is better

Grammarly - ChatGPT and Claude are way better, and much more customizable. If I were a human editor I'd be very worried.

On the flip side, using ChatGPT for diagrams made me pay for Mermaid. It might only be a one year subscription.

Proofreaders, perhaps. But spellcheckers are superior, free, battle-tested, and ubiquitous anyway, yet people still can't be troubled to use them. As proof, behold comments on any given HN post.

True, LLMs can convert style — but so far I've found that the edits always pick up an LLM smell.

My pet hypothesis is that genuine upper-echelon writing, editing, and taste-making will become even more valuable than before.

Interesting thread from the other side — I'm building a SaaS invoicing tool right now and this question keeps me up at night. How long until someone just asks an LLM to generate an invoice PDF and skips my tool entirely?

My current bet is that the value isn't in generating the invoice itself (AI can do that), but in the persistent data layer — tracking who owes you, what's overdue, monthly income trends, client history. That's the part that's hard to replicate with a one-off prompt.

But honestly, the line keeps moving. A year ago I would have said "AI can't replace a full dashboard" and now... I'm less sure.

Chegg is a service many students used to get guidance and answers to homework problems for whatever courses they were taking. It was a sinking ship once GPT 4 came out, but GPT 5 was really it's final nail in the coffin.

I don't know any student that really uses it now.

We replaced our CRM with an in-house solution. Since our main use case was simply sending emails to lists, it made more sense for us to manage those lists in Google Sheets and build an LLM-powered workflow for email outreach and nurturing.

Yep. We've canceled some software we could build internally. But biggest win was deploying our own agents to help with the business. So in general, we spend more more money - not less.

Can you tell us more?

Grammarly and Squarespace. I have a Gost Pro newsletter I am replacing next with my own custom solution.

There are a few personal scripts I replaced with an LLM prompt/skill. Can't really think of any subscriptions though.

What about the inpalce corrections when you are typing or do you just copy and paste into a chat?

Not having that is a feature IMO. At work I wrote an .md and asked Rovo (similar to Claude Code) to check it.

In similar news I'll probably stop the tab suggestions in GH Copilot now and just agent all the things.

Are they still in business? They merged with Duolingo, right?

Duolingo is going to teach people wrong so they have to use Grammarly :P
