Alternatives · Markify & Pentonym

A list of similar marks is homework. A verdict is an answer.

Markify is a genuine trademark search tool — it casts a wide net for similar marks, including some common-law sources. The question is what you do with the results. Pentonym turns the search into a decision, and signs it.

Short answer

Markify runs a broad trademark search and returns similar marks for you to interpret, on paid tiers. Pentonym screens US trademarks and returns a three-state verdict — PROCEED, DO_NOT_PROCEED, or CANNOT_DETERMINE — alongside domains, handles, web use and cultural flags, as one signed record, free to start.

The difference

Same starting point, different output

Markify is good at

  • Broad trademark search, including fuzzy matches
  • Some common-law and international sources
  • Depth for practitioners who’ll interpret results

Where Pentonym differs

  • A three-state verdict, not a list to read
  • Five axes — adds domains, handles, cultural
  • An Ed25519-signed, verifiable record
  • Free to start, US-scoped and honest about it

If you’re a trademark professional who wants raw breadth to interpret, a search tool is the right shape. If you’re a founder who wants to know whether to proceed — with the near marks shown, the class weighed, and a record you can keep — that’s Pentonym. Different jobs; we’re honest about which is which.

FAQ

Common questions

Is Pentonym a trademark search tool like Markify?

It uses trademark search as one axis, but the output is a signed decision, not a results list — and it adds domains, handles, web use and cultural checks. It’s scoped to US marks.

Which should a lawyer use?

A practitioner wanting raw breadth to interpret may prefer a dedicated search tool. Pentonym is aimed at the decision moment — a fast, signed screening signal, not a substitute for a full legal opinion.
