Show HN: Hosted JayBase – An append-only data store for safe AI agent writes

https://jaybase.ai

Just launched the hosted version of my JayBase project, which I shared with you guys a few months ago. (https://news.ycombinator.com/item?id=48999936) I'm really trying to design it from the ground up to be the way that agents can interact with business data, in the same way they can interact with code (by having a built-in history and built-in auditability, in the same way that coding agents...

Show HN: Martin, A CLI that let's your Agent be your CRM, Built on Jaybase

https://github.com/kyle-visner/martin

Hi HN,In my continued quest to excape App Hell, unify all my business data, and let AI run the the parts of my business that don't make money, I've built Martin. Martin is a CLI that let's your store all your customer data in Jaybase, which is an append only business facts DB I built (link at the end). It works along side my bookkeeping CLI, Martin, so now I have a single, AI Native source of...

Re:The Era of (Good) Personal Software Has Arrived on Thursday August 06, 2026 @04:41PM (#49202231)
I agree, I think the era of trying to adapt your work, business, or life to work the way a project manager or app designer thinks is best for you needs to come to an end. Our tools should adapt to meet our needs, we should not need to adapt to fit our tools.
I would be very careful about basing your career decsions based on this trend. The data center build out will always be very boom and bust, which would really suck to work in. One year you would be making 300k working on dataceters and the next you would make 30k because thousands of electricians are now competing to build a few single family homes.
Considering it was made legal at the federal level, that is where the reforms will need to be. Also, having individual states try to regulate and online marketplace would be hell. You would always just be a VPN away from accessing it anyway.

Show HN: Magpie, a CLI to Turn Your AI Agent into a Bookkeeper

https://github.com/kyle-visner/magpie

Hi HN,Annoucing the release of Magpie, a CLI tool which turns your AI agent into an expert bookkeeper, based on Jaybase. (https://news.ycombinator.com/item?id=48999936)As someone who owns a small, tech business, I have very simple books. somewhere between 10-30 transactions a month, a few depreciation line items, and a couple budgets to monitor. So it always bothered be that I was paying...

How does it handle chron jobs or waking from a messaging app?
I'm curious how this will play out. So far having agents in a group chats with multiple people is hard. Either the agent creates a different "thread" internally for each user and everyone has a 1 on 1 convo with the agent in the same group chat, or it's just chaos.

Show HN: Jaybase: Append-only fact store for AI doing business workflows

https://github.com/kyle-visner/jaybase

Hey HN,I build custom AI agents for businesses, and one of the things I've noticed is that everyone wants to use AI to do real, critical work, but it's hard to trust it because sometimes agents can go a little off the rails. No one wants their agent deleting all their customer data or screwing up their books. So they tend to limit its use to searching, summarizing, and as a writing assistant....

Re:Kimi Work on Tuesday July 21, 2026 @06:13PM (#48999083)
Yea, but those aren't subscriptions with fixed costs. I'm wary of running my dev flow against a pay-per-token endpoint, since costs can easily explode doing that.

A note on your website, when I hit the EN button in the top right, it presents a pop-up in German, which I can't read, so I can't change it to be in English.
Re:Ziggity – A terminal UI for Git, written in Zig on Monday July 20, 2026 @02:48PM (#48983181)
Very cool, but if I'm prompting / looping an AI agent as my main development process, what is the use case here? I feel the biggest help would be to make Reviewing PRs from the terminal easier, I care less about commit logs and status.
Re:Kimi Work on Monday July 20, 2026 @02:44PM (#48983120)
I wish they had some kind of US hosted option, NDR policy, or something like that. I love the price and power, but I have concerns around data sovereignty and leaking IP to an overseas company.
I have been so ahead of the curve on this, I'm going to live forever!
Re:Martin Fowler: Technical, Cognitive, and Intent Debt on Wednesday April 22, 2026 @02:31PM (#47867445)
I agree, but that formal language doesn't need to be executable code.
Re:Martin Fowler: Technical, Cognitive, and Intent Debt on Wednesday April 22, 2026 @01:19PM (#47866462)
I see what Martin is saying here, but you could make that argument for moving up the abstraction layers at any point. Assembly to Python creates a lot of Intent & Cognitive debt by his definition, because you didn't think through how to manipulate the bits on the hardware, you just allowed the interpereter to do it.

My counter is that technical intent, in the way he is describing it, only exists because we needed to translate human intent into machine language. You can still think deeply about problems without needed to formulate them as domain driven abstractions in code. You could mind map it, or journal about it, or put post-it notes all over the wall. Creating object oriented abstractions isn't magic.

Re:AI Agent Has Amnesia on Wednesday April 22, 2026 @01:13PM (#47866401)
I've tried a bunch of these "memory" systems and they aren't there yet.

There is, currently, a tension between memory, and context pressure on the coding agent. There have been multiple studies now that tools like codex and claude code get worst at coding as their context window fills up.

As you start adding skills, memory systems, plugins and then a large code base on top of it, I've personally seen the agent start to flounder pretty quickly.

We need a way for agents to pull adhoc memory as they are going along, in the same way we do, rather than trying to front load all the context they might need.

Re:Cursor 3 on Thursday April 02, 2026 @07:37PM (#47621615)
I find a lot of these IDEs are simply not as useful as a CLI. When I'm running a full agentic workflow, I don't really need to see the contents of the files at all time, I'd actually say I often don't need to at all, because I can't really understand 10k lines of code per hour.
So most messaging apps rely on a phone number or centralized server to provide a means of making atleast the initial connection. In a purely P2P messaging system, how do I, as a user, find the other person I might want to talk to?

I can't say I needed yet another reason to hate the current state of LinkedIn, but I am not surprised in the slightest.
Re:Track changes in Markdown, for humans and AI on Thursday April 02, 2026 @12:43PM (#47616806)
Two quick questions/thoughts:

1) Reading the changes, as a human, is not easy, having a document with a bunch editing marks in it, especially at the rate AI can make edits to things, would be very hard to keep track of, atleast that's how I feel.

2) Since you are tracking the context change forever, as a project developed over time, wouldn't the size of the context grow over time, with no upper bound. Would this cause memory pressure issues once we are talking about a huge codebase and a huge Changedown context?

Re:Show HN: Playwright Test Studio on Thursday April 02, 2026 @12:37PM (#47616753)
This looks pretty cool, would love to try it.

One thing I'm trying to understand from the docs. I have 100s of playwright based BDD tests in my projects, especially the ones that are purely AI written. How does this interface with my existing tests? Does it scan the repo or is it meant to have it's own stand alone folder?

Re:Ask HN: How far off are AI virtual games? on Wednesday April 01, 2026 @06:29PM (#47607356)
You could certainly build that today, mario tennis had ai controlled virtual tennis players 20+ years ago. You would simply need to put two of them opposite each other and you could create this. It's just not very compelling to watch two video game npcs do things.
Depends on how hard the question is.

Simple functions in small code bases, will probably work.

Once you get large code bases and more complex work, you'd have issues with the small LLM having the context it needs to actually solve the issue.

Re:Walmart: ChatGPT checkout converted 3x worse than website on Thursday March 19, 2026 @03:49PM (#47444893)
That doesn't seem terribly surprising, a human can quickly look through a grid of shirts to find one they like. ChatGPT would be guessing what they might want and the human would probably get a bad experience there with some regularity.
Maybe this is going over my head, but how do you reduce something like a computer vision system for a ROS2 robot down to a mathmatical proof?
