Your Reddit Saves Are Already a Knowledge Base
You have spent years curating Reddit threads on topics you care about. The missing piece is not more saving - it is a system that lets you search, organize, and query that knowledge from your AI tools.
How it works
Install the extension
Add Readdit Later to Chrome, Brave, Edge, or Arc from the Chrome Web Store. Takes under a minute.
Your saves sync automatically
Every post and comment you have saved on Reddit is imported and kept in sync - no manual work.
Organize, search, and export
Label, filter, search with AI, export to Notion, and let the agent surface what matters.
Most personal knowledge base (PKB) systems start empty and require you to manually add content. Your Reddit saved posts are the opposite - hundreds or thousands of curated entries on topics you genuinely care about, accumulated over years of browsing. The content is already there. What is missing is the structure: search, organization, and a way to connect it to the AI tools where you actually do your thinking.
Readdit Later transforms your Reddit saves into a structured knowledge base. Auto-categorization organizes posts by topic the moment you save them. Semantic search finds content by meaning - describe what you remember and it retrieves the right post. MCP connects the whole library to Claude, Cursor, or Windsurf, so your AI assistant draws on your curated knowledge instead of the open internet. The result is a PKB that builds itself from content you already collect.
What you get
Zero-setup knowledge base
Install the extension, connect Reddit, and your existing saves sync automatically. No manual data entry - your knowledge base is pre-populated with everything you have saved.
AI auto-categorization
Each saved post is categorized by topic automatically. Programming, finance, health, cooking, career - your library organizes itself without manual tagging.
Semantic search across everything
Search by meaning, not keywords. Describe what you are looking for and the AI finds it across your entire save history.
Connect to AI tools via MCP
Add your library as a knowledge source in Claude, Cursor, or Windsurf. Your assistant answers from your curated research - grounded, personal, and relevant.
Daily resurfacing
The For You feature surfaces forgotten saves daily based on your interests. Your knowledge base does not just store - it reminds.
Export to your second brain
Send organized saves to Notion, Obsidian, or Markdown. Integrate Reddit knowledge with your existing PKM workflow.
The problem. The fix.
You have saved 500+ Reddit posts on topics you care about - but they sit in an unsearchable chronological list.
Your Reddit saves are the knowledge base - Readdit Later adds the search, organization, and AI layer on top.
Building a knowledge base from scratch feels overwhelming. Adding entries manually is work you never finish.
Auto-categorization and sync handle organization automatically. No manual entry required.
Your AI assistant gives generic answers because it cannot see the research you have already done.
MCP gives your AI assistant access to your curated knowledge. Answers come from sources you already vetted.
Reddit's 1,000-save limit silently drops the oldest content from your library.
The 1,000-limit bypass preserves your complete save history as a growing, permanent library.
