linkjar

Send decks, proposals, PDFs and HTML pages as branded, tracked links from your terminal or your AI agent, then see who opened them, how far they read and what they clicked.

npx linkjar login
npx linkjar send deck.pdf --for "Sam Lee <sam@acme.com>"
npx linkjar activity deck

Requires Node 18+. No dependencies. Install globally with npm i -g linkjar, or run it with npx linkjar.

Log in

linkjar login                 # opens your browser; the token is saved, never printed
linkjar login --no-browser    # over SSH: open the printed link on any device
linkjar login --key lj_...    # or save an API key

In CI or agent sandboxes, set LINKJAR_API_KEY instead. Create keys at Settings → Claude, CLI & API on linkjar.com. The env var takes precedence over a saved login. The login is saved in ~/.config/linkjar/config.json (or under $XDG_CONFIG_HOME), readable only by you. linkjar logout removes it.

Commands

CommandWhat it does
`send <path\->`Publish a PDF, Office file, HTML file, folder with index.html, or HTML on stdin
`update <ref> <path\->`Replace what a link shows; the link stays the same
listRecent documents with view counts
activity <ref>Who opened it, when, how far they read (alias views)
responses <ref>What people submitted or signed on a fillable PDF (--csv for a spreadsheet, --save-signed <dir> for signed PDFs)
link <ref> --name --emailA personal link for one person
settings <ref>Password, email gate, allowed domains, expiry, call-to-action button
room <title> <ref...>Several documents behind one link
open <ref>Open the document's settings page
whoami, login, logoutAccount

<ref> is a link, its slug or its id. Every command has --help with examples. Add --json to any command for the raw API response. In normal output the first line is the link.

linkjar send ./proposal-site --title "Acme proposal" --password hunter22
linkjar send deck.pdf --email-gate --domains acme.com --expires 2026-12-31
linkjar send deck.pdf --cta-label "Book a call" --cta-url https://cal.com/me/intro
cat page.html | linkjar send - --title "One-pager"
linkjar settings acme-proposal --remove-password
linkjar room "Acme deal room" acme-proposal case-study --email-gate

Use --url or LINKJAR_URL to point the CLI at another server, for example a local dev server.

For AI agents

skills/ holds agent skills for Claude Code, OpenClaw and similar agents:

SkillWhat it does
linkjarEvery CLI command: send, personal links, settings, activity, rooms
proposalWrites a client proposal page from a template and sends a link per decision-maker
pitch-deckBuilds a phone-friendly slide deck and sends a link per investor
one-pagerA sell sheet / leave-behind, optionally tailored to one account
case-studyTurns call notes and metrics into a case study (real quotes and numbers only)
follow-upReads activity and drafts who-to-contact-next emails

The writing skills ship a template.html with one <h2> per section, because the viewer reports which headings each person scrolled to. Ways to install them:

  • Claude Code plugin: this repo is also a Claude Code plugin and marketplace (.claude-plugin/):
    /plugin marketplace add rocketgems/linkjar
/plugin install linkjar@linkjar
  • Any agent: copy the folders under skills/ into the agent's skills folder, for example ~/.claude/skills/.

For agents that can't run a CLI, such as Claude.ai or ChatGPT on the web, use the remote connector at https://linkjar.com/mcp instead.

Development

npm test     # node --test: arg parsing, zip writer, fake-server send/activity/refresh, OAuth flow
LINKJAR_URL=http://localhost:8000 node bin/linkjar.js login

How do I install Linkjar?

Does Linkjar need an API key?

Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.

Is Linkjar open source?

Who maintains Linkjar?
