VERDICT

Should I use Anvil?

Anvil is the document infrastructure for AI agents – collect data, fill and sign PDFs over API. Now agents can do real work, in the real world. - useanvil.com

Depends. Buy only if you're a developer team embedding PDF fill, sign, and data collection into a product or AI agent at real volume. Skip if you just need occasional e-signatures — at $425/month entry, it's overkill; use DocuSign or Dropbox Sign instead.

Confidence

Medium. Based on 9 usable public sources; many 'Anvil' search results referred to unrelated products (blacksmith anvils, Anvil Works, World Anvil) and were excluded.
