What it does
Measure trading-card centering down to the millimeter before you send a card to PSA, BGS, CGC, or TAG. Basic mode is fast and bulk-friendly, AI mode does it in one click.
Grade, price and track your trading cards: centering measurement, AI grading, live values for 1,540,000+ Pokémon, TCG, sports and entertainment cards, and portfolio tracking.
Point your camera at a card and get an AI grade with every defect called out , centering measured to the millimeter, and live market values — across 1,540,000+ sports, Pokémon and TCG cards. Then track the whole collection in one portfolio, before you spend $30 to find out what it's worth. Camera scans, AI grading with close-ups, Grade Certificates, price alerts, portfolio and the collector community live in the app. Very strong front — excellent corners, edges and surface. The back carries minor whitening on the top corners and light left-to-right centering drift, which is what holds the overall to a Near Mint-Mint. Grade it, measure it, price it, certify it, track it and talk about it —…from cardcenteringtool.com

This is a free tool that helps you manage and visualize your credit card rewards across different categories. You can input the cards in your wallet and see how they complement each other, spot gaps in your setup, and also see the best card to use for a given merchant. I’m also a founder at OneCard, where we’re building a smart card that’ll eventually handle all of this automatically, routing each purchase to the best card in real-time. Would love feedback from the HN community!

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
