About Dewey

It ingests from X, Bluesky, LinkedIn, Threads, TikTok, Instagram, Reddit, Mastodon, Substack, and Truth Social, and puts them in a unified library with AI auto-tagging and nested folders. Browser extension (Chrome) and web app only, no native mobile.
Pricing: Free (manual sync, one account), Pro at $10/mo monthly or $7.50/mo annually, Lifetime at $225, and an $8.50 one-off 'Export Pass' that unlocks the export feature for 48 hours without a full subscription.
