Driftless
← Automated drift detection, now available →

Your README is
lying to your users.

Every PR you merge makes your docs slightly more wrong. Driftless reads your code, generates accurate READMEs, and tells you the moment they drift out of sync.

Documentation that stays in sync with your code

Six features built for developers who care about quality docs but don't have time to write them.

Roast My README

Get a brutal letter grade and specific, actionable issues for any public GitHub repo — no login needed.

Smart Code Analysis

Reads your actual package.json, env files, routes, and CI configs — never guesses your stack.

Accurate README Gen

AI generates docs grounded in your real code: exact commands, real dependencies, actual API routes.

Auto PR Creation

Creates a GitHub branch, commits the new README, and opens a pull request — one click.

Doc Drift Detection

Re-analyzes your repo over time and scores README staleness — with a history chart to track trends.

Docs CI GitHub Action

Add a drift check to every push. Fails your CI if README falls below your score threshold — keeps docs honest automatically.

How it works

From code to PR in 60 seconds

No forms to fill. No descriptions to write. Connect your repo and get professional documentation automatically.

Step 01Connect

Connect Your GitHub Repo

OAuth in with GitHub. Driftless fetches your file tree, manifest, env config, and CI workflows — reading your actual code, not just your repo description.

AI Generates Pinpoint-Accurate Docs

AI produces a structured README using only the data it actually found — no invented features, no generic boilerplate, no hallucinated tech.

Testimonials

Loved by engineers worldwide

Join thousands of developers who've stopped writing READMEs by hand.

I was skeptical but the analyzer actually read my package.json and generated commands that work. First tool that didn't need me to describe my own project.

Full Stack Developer · @alexchen_dev

The drift detection is the feature I didn't know I needed. Pushed a breaking change last week and got flagged before any contributors noticed the docs were wrong.

PS

Priya Sharma

OSS Maintainer · @priyacodes

Roasted my README and got a C. Genuinely embarrassing but accurate. Fixed it in 10 minutes with Driftless. Now sitting at 94.

Marcus Webb

Senior Engineer · @marcuswebb

The PR creation is what sold me. Generate → raise PR in one click. I've done this 8 times in two weeks.

Sarah Kim

DevRel Engineer · @sarahbuilds

Finally a tool that understands that README maintenance is infrastructure, not an afterthought. The weekly alerts actually changed how our team ships.

DT

Daniel Torres

Engineering Lead · @dtorresdev

Analyzed 12 repos in one afternoon. Some of my older projects had READMEs so bad I was embarrassed. All fixed now.
