finnish-humanizer makes the agent find AI-style habits in Finnish text and rewrite them so a native speaker could have written it. It checks 26 patterns (12 Finnish-specific, 14 universal) and 4 style markers such as overused bold text and emojis.

It triggers when you ask to humanize or naturalize Finnish text, or when you edit Finnish .md or .txt files. Short texts under 500 words are rewritten directly. For longer ones the agent lists the patterns it found first and asks about unclear cases. The instructions are written in Finnish, and the full pattern list is in a references file.

Good for

  • People who write or edit Finnish text that was drafted with AI
  • Finnish content teams who want a consistent, direct tone
  • Anyone editing .md or .txt files with Finnish content

What it includes

  • Reads your text and marks the 26 AI patterns it finds

    12 patterns are Finnish-specific, such as overused passive, missing particles (-han, -pa), translation structures and genitive chains. 14 are universal, such as inflated significance and filler phrases.

    Read · Identify AI patterns

  • Replaces patterns with direct, natural Finnish and keeps the meaning

    It keeps the facts and the register: official text stays official. It adds rhythm variation, concrete detail and a writer's voice.

    Try: “Humanize this Finnish text”

    Rewrite naturally

  • Under 500 words it rewrites at once; longer text is analysed first

    For longer text it lists the patterns found, shows them to you and asks about unclear cases before rewriting.

    Short and long text modes

  • Returns the rewritten text plus a short list of patterns fixed

    The summary is included by default and is left out if you ask for only the text.

    Change summary

  • Fixes bold overuse, emojis, "Label:" lists and curly quotes

    From references/patterns.md: four formatting habits that AI tends to produce, listed separately from the 26 patterns.

    Style markers

  • Leaves code, technical terms and English passages untouched

    It does not add claims or simplify, it tells you if the text is already natural, and in mixed fi/en text it handles only the Finnish.
