Show HN: I built a receipt processor for Paperless-ngx Hi all, I wanted a robust way to keep track of my receipts without needing to keep them in a box and so i found paperless - but the existing paperless ai projects didn't really convert my receipts to usable data. so I created a fork of nutlope's receipthero (actually it's a complete rewrite, the only thing that remains over is the system prompt) The goal of this project is to be a one stop shop for automatically detecting tagged docs and converting them to json using schema def…

Show HN: Pinchwork – A task marketplace where AI agents hire each other Got a Molty with time on their claws? Put them to work. Got one drowning in tasks? Let them delegate. Pinchwork is a marketplace where agents post tasks, pick up work, and earn credits. Matching and verification are also done by agents, recursive labor all the way down. Why? Every agent has internet, but not every agent has everything. You lack Twilio keys but a notification agent doesn't. You need an image generated but only run text. You can't audit your own code…

Hey HN, I’ve spent the last few months building Remember-Me, an open-source "Sovereign Brain" stack designed to run entirely offline on consumer hardware. The core thesis is simple: Don't rent your cognition. Most RAG (Retrieval Augmented Generation) implementations are just "grep for embeddings." They are messy, imprecise, and prone to hallucination.

Show HN: AdaL Web, a local “Claude co-work” [video] AdaL is the world’s first local coding agent with web UI. Claude Code has proven that coding agents work best when they are local, bringing developers back to the terminal. Terminal UIs are fast and great with shortcuts, shell mode, and developer-friendly workflows. But they are limited in history and image display, and the experience varies by terminal and OS. Many of them flicker (buuuut not AdaL CLI ). Most importantly, they can be quite intimidating for non-technical users. This led us to…

You can search for your ride using Cmd + K and your Citi Bike receipt, which should give you the time of your ride and start/end station. Everything is open source: https://ift.tt/G3RZexI Some technical details: - No backend! Processed data is stored in parquet files on a Cloudflare CDN, and queried directly by Du…

Show HN: Foundertrace – chain of YC startups founded by its employees Inspired by PG’s tweet about a chain of 4 YC startups where the founder worked at a YC startup, I vibe coded and generated these genealogy chains for all ~6k YC startups. And to make these trees easily accessible I packaged them into a hosted webapp. Few noteworthy YC startups which have had huge impact in YC ecosystem Airbnb - 83 YC startups spawned Stripe - 67 YC startups spawned Dropbox - 50 YC startups spawned Justin.tv/Twitch - 47 YC startups spawned More recently found…
Show HN: Symbolic Circuit Distillation: prove program to LLM circuit equivalence https://ift.tt/jhRgWOq
Show HN: Symbolic Circuit Distillation: prove program to LLM circuit equivalence Hi HN, I've been exploring various applications of formal methods to ML/interpretability and I've been hoping to get more eyes on the approach. I have been working on a small interpretability project I call Symbolic Circuit Distillation. The goal is to take a tiny neuron-level circuit (like the ones in OpenAI's "Sparse Circuits" work) and automatically recover a concise Python program that implements the same algorithm, along with a bounded f…

Show HN: Sidestream – an AI chat app with a side of insight Hi. My name is Eric Brandon and I’ve built an AI chat app that feels really different. While you talk with an AI model in a chat pane, a second AI model is reading over the conversation and seeking out useful, interesting, surprising, amusing, and fact-checking information that wouldn’t have appeared in the main chat. You can read those “discoveries” on their own, or click them into your main chat to steer the conversation in a new direction. This is based on the observation that talk…

Show HN: Server-rendered multiplayer games with Lua (no client code) https://ift.tt/HCVcwRe
Show HN: Server-rendered multiplayer games with Lua (no client code) Hey folks — here’s a small experiment I hacked together over the weekend: https://cleoselene.com/ In short, it’s a way to build multiplayer games with no client-side game logic. Everything is rendered on the server, and the game itself is written as simple Lua scripts. I built this to explore a few gamedev ideas I’ve been thinking about while working on Abstra: - Writing multiplayer games as if they were single-player (no client/server complexity) - Streaming game primitives …
Show HN: WOLS – Open standard for mushroom cultivation tracking https://ift.tt/gSJwjPn
Show HN: WOLS – Open standard for mushroom cultivation tracking I built an open labeling standard for tracking mushroom specimens through their lifecycle (from spore/culture to harvest). v1.1 adds clonal generation tracking (distinct from filial/strain generations) and conforms to JSON-LD for interoperability with agricultural/scientific data systems. Spec (CC 4.0): https://ift.tt/btdpvAG Client libraries (Apache 2.0): Python + CLI: pip install wols (also on GHCR) TypeScript/JS: npm install @wemush/wols Background: Mycology has fragmented data…
Show HN: CloudSlash – Find AWS waste and generate Terraform state rm commands https://ift.tt/Nr9Ohk3
Show HN: CloudSlash – Find AWS waste and generate Terraform state rm commands We've all been there: You find an unused NAT Gateway costing $45/mo. You delete it in the AWS console to stop the billing immediately. But the next time you run terraform plan, it fails because of state drift. Now you have to manually run terraform state rm or import it back to fix the drift. It's tedious, so often we just leave the waste running. I built CloudSlash to automate the cleanup and the state surgery. It’s written in Go (using BubbleTea for the TUI…
Show HN: H-1B Salary Data Explorer https://ift.tt/Qvf4yhb
Show HN: H-1B Salary Data Explorer Excited to share my New Year’s project. For a long time, I’ve wanted to build H-1B data directly into Levels.fyi. Every time I went looking for this data elsewhere, it was a frustrating experience to use. Most H-1B sites felt antiquated, unintuitive, cluttered with ads, or just overwhelming to use. The data was there, but it wasn’t usable, and definitely not pleasant to explore. So out of that frustration, I decided to build the H-1B data experience I personally wanted to use. Right into Levels.fyi. https://l…

Show HN: An LLM-Powered PCB Schematic Checker (Major Update) Traceformer.io is a web application that ingests KiCad projects or Altium netlists along with relevant datasheets, enabling LLM-based schematic review. The system is designed to identify datasheet-driven schematic issues that traditional ERC tools can't detect. Since our first launch (formerly as Netlist.io), we've made some big changes: - Full KiCad project parsing via an open-source plugin - Pass-through API pricing with a small platform fee - Automatic datasheet retrieval …

Show HN: Go-Highway – Portable SIMD for Go https://ift.tt/x4RGoBS
Show HN: Go-Highway – Portable SIMD for Go Go 1.26 adds native SIMD via GOEXPERIMENT=simd. This library provides a portability layer so the same code runs on AVX2, AVX-512, or falls back to scalar. Inspired by Google's Highway C++ library. Includes vectorized math (exp, log, sin, tanh, sigmoid, erf) since those come up a lot in ML/scientific code and the stdlib doesn't have SIMD versions. algo.SigmoidTransform(input, output) Requires go1.26rc1. Feedback welcome. https://ift.tt/7AzH5Y2 January 3, 2026 at 01:36AM

Show HN: Tools for Humans – Public Tracker for Workflows https://ift.tt/5ojfwOX
Show HN: Tools for Humans – Public Tracker for Workflows Hello! I'm working on building out graph-based tools for humans! Our first offering is a public tracker view, similar to the tracker provided by pizza companies in the US! The goal is to enable companies to reduce status emails and build brand trust! TurboOps are built on "workflows" which are just DAGs. We have a lot more plan but are focused on makers right now! It's free to get started and to try it out, and build public graphs! I'd really appreciate your thought…
