Stop writing outdated code. DevDoc is a VS Code extension that ensures your AI-generated code is always correct and secure by using a real-time documentation vector store.
Stop using stale AI. DevDoc brings live docs into your code suggestions.
In 2025, a major Next.js vulnerability (CVE-2025-29927) exposed how dangerous outdated AI tools can be. While most coding assistants kept generating vulnerable patterns, DevDoc ensures your code is secure, accurate, and up-to-date—always.
DevDoc is a VS Code extension that combines OpenAI’s GPT-4o with real-time documentation embeddings. Instead of guessing from frozen training data, it pulls live documentation from frameworks like Next.js, Tailwind CSS, and more—so your AI code suggestions actually match today’s APIs, not last year’s.
- 🧠 LLM + RAG: GPT-4o + vector search over live, embedded docs.
- 🧩 Framework-Aware: Understands breaking changes in tools like Tailwind CSS v4 and Next.js middleware.
- 🛠️ Tool Calls: Fetch specific docs, versions, or security warnings when needed.
- ✍️ Diff Viewer UI: Review and apply code suggestions from inside your IDE.
- 🔐 Secure-by-Default: Warns you about known CVEs and deprecated patterns.
