My customer unsubscribed. But I'm happy

A customer has discontinued using or invoicing service. And I have a smile on my face.They were an agency in the medtech sector, making 7 figures a year. They needed an invoicing solution that wasn't rigid. And they found us.And they subscribed. Despite us being in very very early stages.They put up with the problems with the system in the early days, and patiently provided constructive...

They are just thoughts and feelings

Things come into our heads as thoughts and feelings. That's all. Thoughts and feelings. Nothing more than that.They are not things to do. They are not things to worry about. They don't come into our heads as projects to work on. They don't come into our heads as items to tick/check off. They don't even come into our heads as things to even think about!It is us that decide whether those thoughts...

Hiking's on my list too.

Just spent 4 days in the fjords of Norway. Planning to go back for a longer stay (and hike!)

But nobody's hiring. All AI :)

Thanks for the Ask HN suggestion.

Ask HN: What Do You Do?

Ok so AI is now doing all the jobs. Even the manual ones. And you, and everyone else, are getting a universal basic income that's equivalent to a director level job salary in your location. You don't have to "work" to earn a living.So what do you do now?

Spec and Data

Spec + DataNot a fully formed thought, and apologies for the brain fart, but...This post was inspired by an article on latent.space about how, first, human coding "died". Then now we're going to see the demise of the "pull request".If you're not familiar, a pull request, or "PR", is a request to change some code in software, by introducing some new code that you have written yourself.

Hi all,

I built a simple posture monitor that runs in the browser. Why? Because my neck pain has gotten to epic proportions, and this not making me happy.

Finally put it online today, so if you want to try it out, here it is: https://posturemonitorapp.com.

No installation, no signup, none of that BS. Just go to the URL and start monitoring. Yeah, it's free.

If you do use it, please do let me know what you think. I'd love to know what I can do to improve it.

Thanks!

Quick Thoughts on Agents

So someone mentioned that OpenAI's Deep Search is now better then their research team that was hired for $150k. See https://x.com/blader/status/1886547925612028329AI Agents like Deep Research is allowing (almost) everyone to research anything in detail. I wonder what the implications are...3 quick thoughts:1. The rich will get richer/healthier/smarter. People with money will always have access...

Show HN: Autofill dates and time slots in Notion

https://app.popinvoice.com/datepop

Hello!Merry Christmas and I hope you’re having quality time with your friends, family, and yourself!So I’ve been working on a new feature for my Notion date autofiller, and it is now launched: automatically create date and time slots for each day!This has been a slog, TBH. It's supposed to be a quick build but it took ages! Thanks to overthinking, and over-engineering :). I had to pause and cut...

3 months ago I built and launched ClarifyPDF.com, a "chat with PDF" app, mainly to learn how to build a chatbot, and to learn what's it like to launch a SaaS around this type of GPT app. I share my lessons and observations in this post.

I launched a new “AI” SaaS a week ago. Some numbers and learnings

7 days ago, I launched my new SaaS, ClarifyPDF. You upload a PDF for $1.99 and then chat with it. No signups or subscription. Just a one-time payment.Here are some stats since launch.- Visits: 870- Average time on site: 1 min.- Conversion: 4.8% (42 purchases)- Abandoned carts: 260 (30% - ouch)- Revenue: $44.45- Refunds: 1- Disputes: 1- User feedback: 10- Mailing list signups: 92- Picked up by...

Thanks for that.

What about it being $2 is going to bring abusers?

Thanks everyone for your input. More than anything, it's been really great at making look at the bigger pricing picture.

My conclusion:

I'm not going to put in a free tier, because as @brudgers mentioned below, if they can't spend $1.99 to try it, then they're not my target market.

So, in words I read somewhere else before, instead of downgrading my product, I should upgrade my customers.

I will instead spend time creating a high quality product.

And slowly raise prices as I improve the product.

Thanks again, everyone.

This is what I'm debating too. Thanks.
Thank you. That's just an off-the-shelf template from https://tailwindui.com!
I like the cookie idea. Thanks.
You've put in words what's been in my gut. Thank you.
Hmm, some interesting suggestions there. Thanks!

Captcha is a good one and easy to implement for now. Will do that.

Sorry, to be more precise, "same document" could mean the same content but in different formats. OR just slightly tweaked to result in a different hash each time. Harder to abuse for sure, but still has holes.
BTW, the web app is at https://clarifypdf.com, if you need to see what it is first.

Ask HN: Ideas for offering a free trial without users abusing it?

Hi. Hope you guys can help with a conundrum I'm having.Background:I have a web app that lets people upload a PDF and then ask it questions (one of those "Chat to a PDF" apps). The answers come from OpenAI's API in the backend. I charge $1.99 per upload.There is no signup, but they do have to provide an email address during upload. And I don't want to add signups and logins, etc.The challenge:I...

Thanks for that feedback.

That UX flow seems strange because the screen flow should just be: 1) upload, 2) pay, 3) chat. It shouldn't have asked you to check your email for anything.

Please feel free to email me at alfarez at gmail dot com if you're still seeing this issue.

As for handling large files, I'm using a popular method of breaking down the doc into small chunks and then just sending the relevant chunks to the AI.

How to pick the "relevant" chunks? Use embeddings and search for the embeddings that are "semantically closest" to the question being asked.

I wrote up an outline of this process here: https://farez.me/how-to-create-a-chatbot-with-openais-api-a-...

Only on GPT-3.5 at the moment, so token length is only 4097. Still waiting for GPT-4 API access!

But you can upload up to 10MB in file size.

Launched my side project today: https://clarifypdf.comIt's a simple web app to help you clarify long complicated PDFs by asking it questions. How it works:- Upload a PDF - Ask it questions - It gives you answers, based on the PDF, generated by OpenAI's GPT-3.5 model.Yes, it's not new, but with mine, there's no subscription of signup. Just a one time $1.99 payment per doc. So yes it is a paid...
