They have strict specifications about the types of nails and wood that they can hammer, but they're not documented anywhere. If you send them the wrong type of nails or wood, they'll put them both into an industrial shredder and send you back the dust, because technically the nails have now been integrated with the wood.
Their free plan will let you hammer in 5 nails per month into a single piece of wood, but you can't use a different piece of wood each month. For $30/month you get 50 nails, and up to 5 pieces of wood, or for $60/month you can get 120 nails and unlimited pieces of wood, and two-factor (they'll call you before they hammer in the nails, and ask where you actually want the nails hammered). If you want to have unlimited nails, you have to contact them for enterprise pricing.
They will also sell the measurements of your wood and the nail positions to other carpenters.
