Dewey vs Keep
Dewey organises social bookmarks. Keep stores mixed research as Markdown. Both can take private X bookmarks as a source. That overlap is where the confusion starts. Dewey is the social client. Keep is the library the useful posts graduate into. Neither is an X analytics exporter.

Feature comparison
Dewey wins social-network coverage and a UI built for posts. Keep wins Markdown, agent access, and every non-social source. The X bookmark column is not the whole story.

Strengths and weaknesses
Dewey's strength is depth in one category. Keep's strength is putting that category next to everything else you save, in a format agents can read.
What Dewey does well
- One of the only tools that syncs X bookmarks natively

Which one should you pick?
Pick Dewey if…
Your habit is posts, not articles. You want one UI for X, LinkedIn, Bluesky, Threads, TikTok, Reddit, and the rest, with AI tags and nested folders. You accept web plus Chrome, no native mobile, and export gated behind Pro or a 48-hour Export Pass.
Pick Keep if…
You want a searchable Markdown library. Public X posts save on Personal. Private bookmark sync is a $5 add-on. Historical backfill is import-from-file, not a promise to scrape your entire X history. You also save web pages, transcripts, feeds, and files into the same place.
About Dewey
Dewey is a niche tool aimed at one specific problem: saving and organising bookmarks from social platforms. 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 a $50 one-off Export Pass that unlocks export for 48 hours without a full subscription.
About Keep
Keep saves articles, posts, videos, feeds, files, and notes as clean Markdown. You can read the library yourself, search it, export it, or let Claude Code, Cursor, Codex, ChatGPT, and other clients use the same context over MCP or CLI. Starter is free for bookmark saves and a limited note library. Personal is $10/month and adds full-content Markdown, search, sources, automations, and agent access. X bookmark sync is a $5 add-on for automatic private bookmark import.
Frequently asked questions
Not as a clone. Dewey still covers more social networks with a dedicated workflow. Keep saves public posts and can sync private X bookmarks. It does not try to be the best LinkedIn or TikTok bookmark client.
Keep does not scrape your full X timeline. Use a browser exporter, then import CSV or JSON. X Sync can pull new private bookmarks and a capped recent backfill after you connect an account.
Neither, if you only want a file. Dewey's Export Pass is $50 for 48 hours. Keep import is not an exporter. A dedicated Chrome exporter is the cheaper path for CSV or JSON alone.
No. Keep ships Markdown per item, bulk export, MCP, CLI, and an API. That is the usual reason to move a mixed library into Keep even if Dewey remains better at social-only capture.
Not native iOS or Android. Capture is the browser extension, the web app, email, API, and MCP. Dewey is also web plus Chrome, so mobile is not a Dewey win either.
Yes. Stay in Dewey for social triage if that UI is the habit. Export or copy the posts you actually need into Keep when they become research. They only conflict if you expected one app to do both jobs perfectly.
Raindrop is the polished general bookmark manager. It does not sync your private X bookmark list. See Dewey vs Raindrop if the decision is social-only vs classic bookmarks rather than Markdown-for-agents.
Export Dewey as CSV (Pro or Export Pass), keep an untouched copy, then import through Settings, Data, Import in Keep. Spot-check URLs, titles, tags, and dates before you drop Dewey.
