Built by a linguist, for linguists

Linguistics Toolkit

Free, interactive tools for phonetics, phonology, syntax, and morphology. Designed for students, educators, and researchers.

No signup. No ads. No tracking. Just tools that help you learn and teach linguistics.

Phonetics & Phonology

Tools for studying speech sounds and sound systems. Explore the International Phonetic Alphabet, compare how languages organize their consonants and vowels, find minimal pairs for teaching, and generate vowel charts for academic papers.

Morphology & Words

Analyze word structure and discover relationships between words. Break words into morphemes, count syllables, find rhymes and homophones — all powered by phonetic data from the CMU Pronouncing Dictionary.

Syntax & Structure

Visualize sentence structure and grammatical relationships. Build phrase-structure trees with bracket notation or drag-and-drop, and export publication-ready diagrams for papers and assignments.

Languages & Typology

Explore how the world's languages are related. Navigate an interactive family tree covering 250+ languages across all major language families, with data on speakers, writing systems, and geographic distribution.

Built by a Linguist

These tools are designed and built with real classroom and research needs in mind — from the IPA chart that plays audio for each symbol, to the morphological analyzer that uses proper linguistic glossing conventions.

Unlike generic online tools, Fixie's linguistics toolkit is purpose-built for academic use. The phoneme inventory data comes from peer-reviewed typological sources, the minimal pairs are curated for ESL/EFL teaching contexts, and the syntax tree builder supports multiple linguistic frameworks. All tools are free, require no signup, and respect your privacy.
