News from Riddler. We publish when there is something to say.

  1. The same trip, ten case files

    Ten procedures from the same trip should be findable together, without merging them or renaming them all the same.

  2. A closed case is never reopened

    Closing is a decision. If the matter continues, you open a new case file linked to the previous one, and the closed file stays as it was.

  3. Praxis, from your assistant

    Cursor, Claude, ChatGPT, Grok, or Gemini can read and move your case files — with exactly your permissions.

  4. Where is my file?

    A tracking code, a work inbox, and a history nobody rewrites. What Praxis actually does, from both sides of the counter.

  5. Change the procedure, not the software

    Stages, moves, and forms are things you edit in Praxis, not things you request from a developer.

  6. Documents you can prove

    A signed PDF has to stand on its own. Why Riddler built Sigil around verification, not only the click.

  7. Sigil certifies, Praxis orchestrates

    Riddler’s two products, in one sentence each, and why they exist together.

  8. The site, again

    riddler.com.ar is published again. The public work is Sigil and Praxis; the site now says so.
