Launching Q2 2026

Never Manually Update
API Docs Again

DocuLens reads your codebase, tracks every git push, and regenerates accurate documentation in seconds — so your team ships code instead of fixing stale README files.

“47% of developers cite poor documentation as their #1 API frustration” — Postman State of the API 2025

Your Docs Are Lying to Your Users

Every stale doc line costs you time, money, and trust

📉

The Documentation Drift

Your API evolves daily, but docs update monthly. Your code says userId is optional — your docs say required. Developers waste hours debugging problems that shouldn't exist.

Average: 6+ hours/week on doc maintenance

🎫

The Support Ticket Avalanche

“This endpoint doesn't work like the docs say.” Sound familiar? Every wrong parameter type, every missing example, every outdated response schema becomes a support ticket your team has to answer.

Cost: ~$23,000/year in wasted developer time

🤝

The Trust Tax

When integration is painful, developers choose your competitor. Your code might be beautiful, but if docs are wrong, nobody sees it. Bad docs = 30% lower API adoption rates.

Lost: 2-3 customers/year from doc confusion

From Manual Chaos to Automatic Sync

Before

You push a breaking change at 4pm. Three weeks later, a customer discovers the docs are wrong. They email support. Support pings engineering. Engineering updates Notion. The cycle repeats infinitely.

After

You push a breaking change at 4pm. DocuLens detects the diff, regenerates the affected docs, and publishes within 5 minutes. The customer never sees wrong information. Support ticket avoided.

Before

New engineer joins and asks “how do I add a new endpoint to our docs?” Answer: “Copy this other page, change the fields, hope you don't miss anything, then ask Sarah to review it.”

After

New engineer pushes code. DocuLens generates the endpoint docs automatically — with curl, JavaScript, and Python examples. No tribal knowledge required. Sarah reviews code, not docs.

Documentation That Writes Itself

DocuLens connects to your codebase and keeps docs perfectly in sync

🔄

Real-Time Git Sync

Push to main, docs update in minutes. Every commit triggers a re-parse of changed files — no manual triggers needed.

Designed to update within 5 minutes of push

💻

AI-Generated Code Examples

For every endpoint, get working examples in curl, JavaScript, and Python. Not templates — actual examples using your real parameter names.

Copy, paste, it works the first time

🎯

Type-Aware Parsing

DocuLens understands your TypeScript types, Python decorators, and JSDoc comments. It knows userId? means optional.

Native support for NestJS, FastAPI, Flask

📊

Change Detection Diffs

Every update includes a visual diff: what was added, removed, or modified. Review changes before publishing.

Catch issues before customers do

🔍

Instant Search

Semantic search across your entire API surface. Type “how do I create a user?” and find the right endpoint immediately.

No more Ctrl+F through 47 Notion pages

✨

Beautiful, Hosted Docs

Clean, responsive design. Syntax highlighting. Dark mode. Custom branding. Ship docs that look as good as your code.

Zero design work required

How DocuLens Works

From zero to auto-updating docs in under 3 minutes

1
🔗

Connect Your Repository

One-click GitHub OAuth — read-only access. Connect your repo in under 60 seconds. We never write to your repository.

2
🤖

AI Parses Your Code

Our AI reads your actual source files — not OpenAPI specs. It extracts endpoints, parameters, return types, and docstrings.

♻️

Docs Stay Updated Forever

Every push to main triggers incremental updates. Changed files get re-parsed, docs regenerate. Never more than 5 minutes stale.

Frequently Asked Questions

What languages and frameworks does DocuLens support?
At launch, we support TypeScript (Express, NestJS, Fastify) and Python (FastAPI, Flask, Django REST). Go and Ruby support is on the roadmap based on demand from our early users.
How accurate is the AI-generated documentation?
Our goal is 95%+ accuracy out of the box. For complex edge cases, DocuLens shows confidence scores and flags sections that may need human review. You can always edit any generated content before publishing.
Is my code secure?
DocuLens requests read-only GitHub access. Your code is processed securely and never stored beyond what's needed for documentation generation. We never access other repositories in your organization.
How is this different from Swagger/OpenAPI?
Swagger requires you to maintain a separate spec file that can drift from your code. DocuLens reads your actual source code — no additional files to keep in sync. If your code changes, your docs change automatically.
What if I already use ReadMe.io or GitBook?
DocuLens can export to standard formats like Markdown and OpenAPI. Many teams use DocuLens to auto-generate content, then publish to their existing documentation platform. Or switch entirely — your choice.
How fast do docs update after I push code?
Pro and Agency plans update within 5 minutes of a git push. Starter plan updates within 24 hours. All updates are automatic — no manual triggers needed.
Can my whole team access the documentation?
Starter and Pro plans include unlimited viewers. Agency plans include 10 editor seats for teams who want collaborative review workflows before publishing.
When does DocuLens launch?
