Finnish Text Analyser

In Finnish, words transform substantially depending on their role in a sentence. Identical surface forms can represent entirely different parts of speech. For instance, kuusi can be the noun for "spruce" or the number "six", and voi can mean the noun "butter" or the verb "can / may".

Finnish Text Analyser allows you to paste continuous Finnish text (from short idioms to full multi-paragraph articles) and instantly see each word broken down. It uses a hybrid morphological engine combining instant client-side dictionary lookup with AI contextual disambiguation to identify the correct part of speech and render character-level inflection diffs.

• 📝 Paste any text (words, idioms, sentences, or full paragraphs) and analyse every word in context.
• 🧠 Context-aware disambiguation accurately distinguishes ambiguous words like voi, kuusi, and vie based on grammatical context.
• 🎨 Colour-coded character diffs highlight base stems (purple), consonant gradations (amber), suffixes (green), lengthened vowels (pink), possessives (indigo), and clitics (cyan).
• 🔗 Click any analysed word to jump directly into Finnish Word Explorer and inspect its complete inflection paradigm.
• 📱 Fast and mobile-friendly with responsive design and zero app installation required.
