Czech Name Vocative & Greeting Generator (oslovení, 5. pád)

Czech uses the vocative case (5. pád) when addressing people. "Dobrý den, pane Novák" is wrong, "Dobrý den, pane Nováku" is right. Doing this by hand for a contact list is slow, and AI chatbots are not consistent. This actor returns the correct vocative form for every name you provide.

What you get

For each input name, the actor outputs:

Field	Example (for "Ing. Petr Novák")
titles	"Ing."
firstNameVocative	"Petře"
lastNameVocative	"Nováku"
gender	"male"
greetingFormal	"Vážený pane Nováku"
greetingNeutral	"Dobrý den, pane Nováku"
greetingInformal	"Ahoj Petře"
greetingWithTitle	"Vážený pane inženýre"

Who it is for

• Cold email and outreach to Czech prospects
• Newsletters (Klaviyo, Mailchimp, Brevo)
• CRM clean-up (Clay, Make, Zapier, n8n)
• AI agents that write Czech emails

Input

{
    "names": ["Ing. Petr Novák", "Jana Nováková", "MUDr. Lucie Svobodová, Ph.D."],
    "lastNameFirst": false
}

names — Array of name strings. One per line if using the web UI, or as an array in JSON. Each entry is processed individually.

lastNameFirst — Boolean. If true, treat the first part of each name as the surname (e.g., "Novák Petr" instead of "Petr Novák"). Default: false.

Output example

For input "Ing. Petr Novák":

{
    "input": "Ing. Petr Novák",

    "gender": "male",
    "firstNameVocative": "Petře",

    "greetingWithTitle": "Vážený pane inženýre"
}
