Free LinkedIn tools

28 tools, no login, no email. Writers' tools run on a fair-use daily allowance; checkers and calculators run entirely in your browser. Every tool also ships as an installable skill for AI agents. Built by Liftli — the content engine that runs inside the AI you already use.

Every tool, installable by your AI agent

For AI agents

Each tool on this page has a skill twin: a distilled version of the same methodology that your agent runs locally — in Claude Code, Cursor, or any skills-compatible client. Install the whole collection:

Why these tools are free

Each tool here does one step of content work well: a hook, a headline, a score. Liftli is what happens when the steps connect — it runs inside the AI you already use, mines your voice notes, calls and commits for material, drafts in your extracted voice, and waits for your one-tap approval. The tools are free because they're the single-serving versions of things Liftli does on autopilot. If one of them earns a spot in your workflow, you know where the full pipeline lives.
