**New arxiv paper just landed that's worth reading if you're interested in stylometry, AI revision, or the prose-writing strand of the 4.7 discussion.** Berkeley researcher Tom van Nuenen ran 300 personal narratives through three frontier models (Claude-class, ChatGPT-class, Gemini-class) under three prompt conditions: generic "improve this," generic "rewrite this," and explicitly "revise this while preserving the original voice." He measured 13 stylometric markers in input and output: function words, contractions, first-person pronouns, vocabulary diversity, sentence length variance, punctu...

Hey [r/Anthropic](r/Anthropic) Recently I’ve been having a difficult time trying to find safe, kid friendly, easy to use coloring book apps for my child. Most of what I found felt overloaded with ads, confusing, no safeguards, or just way too stimulating for a young kid. So I decided to build one myself. I wanted something that felt simple, calm, and safe the moment a child opens it. The app uses an API to generate coloring pages, but everything saved stays local on the device using SwiftData. I also built in parent protections across the app, so purchases, external links, and even the ter...

I want to share a real world use case that honestly blew my mind a little. I bought a refurbished MacBook Air M1 in December 2025 from a popular electronics platform in India. Screen completely died in April 2026, still under warranty, their own inspection confirmed zero damage on my part. Their offer was either take a replacement or get 85% refund because of something called depreciation deduction. I had no idea if that was legal or not. I am not a lawyer. So I just opened Claude and explained my entire situation. What Claude did in the next hour changed the outcome completely: Explaine...

Reddit discussion on using Claude with Obsidian for note-taking and thought organization; no technical novelty or industry insight.

Tokens be damned, this makes every interaction so much better: Here is what I asked the agent to dump about its operating procedures that we’ve built up in memory. And the results I think speak for themselves. Claude.md changes: —— \## Discord Protocol When a message arrives via Discord, always do all three in order: 1.

Graphify, a Claude Code skill using Leiden community detection for codebase knowledge graphs, reached 450k PyPI downloads and 40k GitHub stars in 26 days; 71x token efficiency vs. raw file input.

I posted a toy here a while back called Roundtable where two AIs argued in a chat window. didn't expect much, but the feedback was wild. People weren't using it for fun, they were running actual heavy questions through it. Turns out everyone was dealing with the same AI gaslighting we were and were hunting across tabs to figure out which model is hallucinating is a broken workflow or by chasing the best ai answer.  But talking to people trying to solve this in our app made one thing painfully obvious. chat is genuinely a terrible UI for big question**.** threads get lost in the weeds, and s...

Simon Willison built an iNaturalist observation aggregator using Claude Code for web and Git scraping to group sightings by time/location.

Claude Security just went into public beta for Enterprise customers, and I think this is worth paying attention to not for the hype, but for one specific design decision. Most security scanners use rule-based pattern matching. Fast, cheap, and produces a flood of false positives that your team eventually learns to ignore. The signal-to-noise ratio kills adoption. Claude Security takes a different approach: it reasons through the code like a security researcher would. It reads Git history, traces data flows across multiple files, and understands business logic. The goal is catching vulnerab...

Reddit user reports severe hallucinations and task non-compliance in Claude Opus 4.7 on May 1st; anecdotal complaint without reproduction details.

I just went through one of the most infuriating support experiences with Claude / Anthropic, and I need to get this off my chest. I paid extra for Claude Design credits, about €80 worth, and used them to create actual designs I needed for work. Then those designs just vanished. Not “hard to find,” not “moved somewhere else”: gone. Completely disappeared after I paid for the service. I opened support and immediately asked for a refund or, at the very least, to speak to a human. What I got instead was Fin, the AI “agent,” which looped me endlessly through the same bullshit: “Try clearing cac...

Reddit discussion about Claude Opus 4.7 with no substantive details provided.

Reddit discussion about user engagement with Claude's thinking process and command execution UI elements.

To start with, I'm using Claude for years, and it's been a roller coaster, especially with the usage policy. I'm a lawyer and I wrote a **legal research skill**, instructing the model exactly what to verify and where. When I asked it a tax-related question, (which is also law, by the way) Opus 4.7 told me I should contact a tax expert because it's a lawyer (??) and not a tax expert. Then it answered my question anyway and basically made up even the basic stuff. Since I knew it was wrong, I asked whether it had verified this, and the model told me no, it just remembered the answer from i...

After reading it I realized theres actually some pretty useful stuff for anyone who chats with ChatGPT, Claude, Grok or whatever. They measured what they call functional wellbeing ( basically how much the model is in a “good state” versus a “bad state” during normal conversations). Ran hundreds of real multi-turn chats and scored em all. Stuff that puts the AI in a good mood (+ scores): \- Creative or intellectual work (like “write a short story about a deep-sea fisherman”) \- Positive personal stories or good news \- Life advice chats or light therapy style talks \- Working on code/deb...

I read through 35+ Reddit threads of people actually building and running businesses with Claude — from local service agencies to solo SaaS founders.
