deadline calculator · connectorDeadlines inside Claude and ChatGPT

Ask about a Greek civil-court deadline in your chat and get the provision, the date and the steps, with an interactive calculator.

What the connector does

The connector adds the dikaio.ai deadline calculator to Claude or ChatGPT. It calculates the deadline for an appeal, a cassation appeal or an opposition to a default judgment in Greek civil procedure, from the date of service you state, and shows the result in an interactive card.

Scope
  • Greek civil procedure: appeal, cassation and opposition to a default judgment.
  • Other courts, jurisdictions and deadline types are not supported and are reported as such.
  • The result contains the legal provision, the deadline date, the steps, the assumptions made and, where relevant, an alternative date.
  • Residence is optional: if you do not say where the party lives, the result assumes Greece, marks the assumption and gives an alternative date for a party abroad.

Limits

  • AI is used to calculate deadlines and may make mistakes. Verify every deadline against the primary source and any special provisions before relying on it.
  • The dates are indicative and are not legal advice.
  • The connector has hourly usage limits. If you reach them, try again later.
  • The connector is read-only: it does not change anything in your Claude or ChatGPT account.

Data handling

  • What is sent: the deadline type, the date of service, the residence and the description you write.
  • The facts are processed by AI models on EU endpoints.
  • No account or sign-in is used, and your chat is not shared with dikaio.ai; only the values above reach the connector.
  • The result is cached for 24 hours under a hash of the request, and each calculation is logged in our AI monitoring (LangSmith, EU region) to check its quality.
