Rules of the Road

Four rules every tool on this river keeps.

  1. Route 1

    No toll at the gate.

    Every tool is free to start, and none of them asks for a card before you've seen it work.

    Seen atFree UntilTLDMathShow Real CostLocalCSVDraftlineVoloMoney

  2. Route 2

    What you carry stays yours.

    If the work can happen on your device, it happens there. We don't collect what a tool doesn't need.

  3. Route 3

    Post the real distance.

    Honest signposts only. The renewal price next to the promo, and nothing estimated without saying so.

    Seen atFree UntilTLDMathShow Real CostDraftline

  4. Route 4

    One road, well paved.

    Each tool does one job and does it quickly — no maze of features between you and the answer.

  3. The signpost gets a horn

    Switch sound on and the signpost sounds one long blast. The woods now turn with the seasons, the tab notices when you leave, and a wrong turn leaves you up the creek with the way back drawn.

  4. Sheet 01 learns to survey

    The page locks down 16 ft into the Atlas. On the map, a survey readout follows the cursor, the town shows its streets, the river takes a skipped stone, and the uncharted arm keeps surveying.
