AI Code Detector – detect AI-generated code with 95% accuracy
Hey HN, I’m Henry, cofounder and CTO at Span (https://span.app/). Today we’re launching AI Code Detector, an AI code detection tool you can try in your browser. The explosion of AI generated code has created some weird problems for engineering orgs. Tools like Cursor and Copilot are used by virtually every org on the planet – but each codegen tool has its own idiosyncratic way of reporting usage. Some don’t report usage at all. Our view is that token spend will start competing with payroll spend as AI becomes more deeply ingrained in how we build software, so understanding how…
AI Code Detector – detect AI-generated code with 95% accuracy launched on September 16, 2025 with 72 votes, #387 of 8,160 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
AI Code Detector is a browser-based tool that identifies AI-generated code with 95% accuracy. It helps engineering organizations gain visibility into code created by tools like Copilot and Cursor, addressing the challenge of tracking AI tool usage across teams. As organizations increasingly rely on AI for code generation, this detector enables better understanding of AI spending and resource allocation, similar to how companies monitor traditional payroll expenses.

AI Code Detector helps teachers, hiring teams, and engineering reviewers scan pasted code or uploaded files for AI-written risk cues, line-level evidence, quality hazards, and source-similarity signals. It keeps raw code out of storage, gives guests 2 free scans and Google users 5, then supports paid review workflows with exportable Markdown and JSON reports.
AI Code Detector finds AI-written code risk, review evidence, quality hazards, and similarity cues before high-stakes decisions.
Spot AI-written risk, quality hazards, and similarity cues before grading, hiring, or shipping. Guests get 2 free scans; signed-in reviewers get 5. Open the console free. Upgrade when the free scans are used. function calculateFactorial(n) { // Step 1: check the base case if (n === 0) return 1; // Step 2: recursively calculate result return n * calculateFactorial(n - 1); } try { processData(resultData); } catch (error) { console.log(error); } Live evidence board The console is built around one primary path: paste code or drop a file, run analysis, inspect the evidence, then export a reviewer-ready report. An AI code detector helps reviewers inspect whether code looks machine-assisted,…from code-detector.ai

We built an AI to review your pull requests2025 · infinitcode.ai · ▲53Hey HN, We’re two developers (co-founders) with a team of 20 who got tired of spending hours reviewing PRs, so we built Infinitcode.ai, an AI-powered code reviewer that: - *Summarizes PRs in plain English*: No more deciphering 1,000-line diff jungles - *Catches more than bugs*: Security holes, performance pitfalls, code smells, even typos (yes, we’ll flag “vurnerabilities” and vulnerabilities) - *Zero onboarding*: Works instantly—no “let me learn your codebase for weeks” nonsense. Why we’re posting: We’re in alpha and need brutal honesty. Roast our tool, mock our UI, or tell us why AI will…
BuildermarkApr 2026 · buildermark.dev · ▲93I made Buildermark to see exactly how much of my code is generated by my coding agents vs what I was writing by hand. For this project, it ended up being 364 agent conversations writing 94% of the code. Browse all of those here: https://demo.buildermark.dev/ It matches edits by your coding agents (scans history in `~/.claude`, '`/.codex', etc.) with git commit diffs. It does formatting-agnostic matching to be robust against auto-formatting and reorganizing code. It's open source and local only, not even any analytics. Everything is automatic... just run the app, open…

The site hit #1 on HN about a year ago. Got enough traffic that I turned it into a proper API. What's there: - REST API — 35k products, manually filterable by category, free key, 60 req/min - CLI — npx anycrap random -c food - faker.js plugin — bundled, no API call, works offline - HuggingFace dataset — full 35k rows for ML/training https://anycrap.shop/developers

I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
