AI tjekker (often called “AI checker” or “AI-detektor” in Danish contexts) is an AI detection tool that scans text to determine whether it was generated or heavily assisted by artificial intelligence models such as ChatGPT, GPT-5, Claude, Gemini, or similar LLMs. These checkers examine linguistic patterns, predictability, sentence variety, and other markers to output a probability score showing how much of the content appears AI-written versus human-authored.
Is AI Tjekker Free or Paid?
AI tjekker tools are mostly freemium. Many provide reliable free access for basic scans—paste Danish or multilingual text, receive an instant AI score and highlights—often without signup or strict daily limits, which suits occasional or moderate use in Danish contexts.
AI Tjekker Pricing
Pricing for AI tjekker varies by platform, with free core detection common and affordable paid tiers for advanced use. Danish-focused tools tend to keep entry-level access very low-cost or free.
Here’s a clear breakdown based on leading examples:
| Plan Name | Price (Monthly / Yearly) | Main Features | Best For |
|---|---|---|---|
| Free / Basic | $0 | Limited words/characters per scan (e.g., 1,200–5,000), AI probability score, basic highlights, Danish/multilingual support, no signup often needed | Students, teachers, bloggers doing quick Danish text checks |
