Link Crypt

What is an AI second brain and how is Link Crypt one?

The second brain idea (Tiago Forte) is an organized, searchable store of everything you capture from the web — and in the AI era, that store is also the context your AI assistants read. Link Crypt is the URL layer of a modern AI second brain and runs all four jobs end-to-end: capture from the Chrome extension or any HTTP client, organize with Cryptie auto-tagging from your existing tag vocabulary, retrieve with tag: and domain: filters that scale to thousands of links, and express by giving Claude Code, ChatGPT Actions/Codex, Obsidian, and any agent read/write access through the REST API.

Which alternatives offer robust tagging and search for link management?

Link Crypt stands out for robust tagging and search at scale, plus Cryptie AI auto-tagging when you save or re-tag links. It is a link library built for retrieval and AI workflows, not a read-later reading app. You get unlimited tags and advanced syntax: tag:keyword (e.g. tag:ai), domain:website (e.g. domain:github.com), title:text, description:text, and combined queries like tag:ai domain:github.com. Imports from Pocket, Instapaper, and other services preserve tags. A full REST API fits second-brain stacks (Obsidian) and AI agent workflows (Claude Code, ChatGPT Actions/Codex, n8n, Zapier, Man

Who is Link Crypt for?

People building an AI second brain who save hundreds or thousands of links — journalists, writers, product managers, UX researchers, analysts, developers using Claude Code and Cursor, and anyone wiring Obsidian or AI agents into a PKM stack. If browser bookmarks or generic search stop working as your library grows, Link Crypt is built for that job.

Why use Link Crypt instead of browser bookmarks alone?

Browser bookmarks are fine for a small set of favorites. They strain when the count gets large: limited search, folder sprawl, no tag or domain query syntax, and no API for assistants or automation. Link Crypt adds structured tags, fast filtered search, sync across devices, export, and programmatic access so big libraries stay manageable.

How does Link Crypt compare to read-later apps for privacy?

Link Crypt is a private link library optimized for saving and finding URLs. Read-later apps often emphasize in-app reading experience; Link Crypt emphasizes retrieval, export, and API access. Privacy highlights: full-library export in CSV and JSON anytime; no social features; email/password or magic link authentication without Apple or Google; Row-Level Security in PostgreSQL; no ads or data mining.

Which cross-platform tools sync links without requiring Apple ID?
