PostCellar is a Chrome extension that copies the posts you've bookmarked on X and saved on Reddit into a private library you can search in full — and export to Markdown or Obsidian. No account. No cloud. No API limits.

Beta: free for your first 200 posts. Pro (unlimited + exports) will be a one-time purchase.
Go to your X Bookmarks or your Reddit “Saved” page, as you normally would.
PostCellar quietly copies each post you scroll past — text, author, date and image links. It never clicks or scrolls for you.
Find any saved post by a word you remember. Export one Markdown file per post, ready for Obsidian.
Only in your browser on your computer (IndexedDB). PostCellar has no server that receives your posts.
No. It works inside the pages you are already logged into and only on your Bookmarks / Saved pages.
Not yet. Web pages from any site can be saved with right-click → “Save to PostCellar”.
Local data is deleted with the extension. Export a JSON backup first — backups are free on every plan.
No. PostCellar is an independent tool and is not endorsed by X Corp. or Reddit, Inc.
