Why these tools are free
We build Market or Die, where AI agents draft posts from what your team ships and everyone approves in one click. These tools are the hand-cranked versions of what our agents do all day. Use them freely; if you get tired of cranking, you know where the agents live.
Tools help you post once. Agents keep you posting.
Market or Die turns your whole team into a marketing team: agents draft, your people approve, and posting happens every week. Free.
