Code Snippet Manager

Your personal library of reusable code.

The Problem

Developers write the same utility functions, regex patterns, and boilerplate code over and over. They know they've solved this problem before—but where? Was it in that old project? A Slack message? Stack Overflow? The code exists somewhere but finding it takes longer than rewriting.

The Solution

A personal code snippet library with semantic search. Save snippets with one click from anywhere, find them instantly by describing what you need in plain English, and access them from your IDE, browser, or mobile. AI auto-tags and suggests related snippets.

How it works:

1

Save snippets

From browser, IDE, or paste

2

AI organizes

Auto-tags, detects language

3

Find instantly

Semantic search by description

Market Research

Developer tools are high-value market. SnippetsLab, Cacher, and others have proven developers pay for snippet management. AI search is the missing feature that makes these tools 10x better.

  • GitHub Gists has 10M+ gists—demand for snippet storage is clear
  • Developers spend 30% of time searching for code (GitLab survey)
  • Raycast snippets feature is one of most-used—validates need

AI Prompts to Build This

1. Project Setup

Create a Next.js app for a Code Snippet Manager. Features: - Dashboard with snippet list (card view, filterable by language/tag) - Add snippet: paste code, add title/description, auto-detect language - Syntax highlighting using Prism or Highlight.js - Search bar with instant results - Folder/collection organization Use Supabase for auth and storage. Include browser extension for quick save.

2. AI Features

Implement AI-powered features: 1. Auto-tagging: When snippet saved, AI suggests tags based on code content 2. Language detection: Automatically detect programming language 3. Description generation: AI generates description if user doesn't provide one 4. Semantic search: Convert search query to embedding, find similar snippets 5. Related snippets: "You might also need..." suggestions Use OpenAI embeddings for semantic search. Store vectors in pgvector.

3. Browser Extension

Build Chrome extension for quick save: 1. Select code on any webpage, right-click "Save to Snippets" 2. Popup shows snippet preview with auto-filled title (from selection context) 3. Quick add tags before saving 4. Keyboard shortcut: Cmd+Shift+S to save selection 5. Floating button on code blocks (GitHub, Stack Overflow) Extension syncs with main app via API. Show confirmation toast after save.
