Each Layer is a purpose-built vocabulary for a domain. Your backend picks a Layer, sends a transcript, and gets clean text back — no model training required.
Agronomy is live today. More industries ship as vocabulary is built and validated with domain experts.
domain: agronomyField chemistry & crop brands
Herbicides, insecticides, fungicides, and adjuvant brand names — the words retailers and applicators actually say in the field.
domain: legalFirms, courts & deal terms
Law firm names, practice areas, clause shorthand, and entity names that generic autocorrect has never seen.
domain: medicalDrugs, doses & charting
Medication names, dosages, and clinical abbreviations spoken fast in exam rooms and dictation workflows.
domain: logisticsCarriers, DCs & routing
Warehouse codes, carrier names, and location shorthand from dispatchers who talk in acronyms all day.
Vocab layer is a backend service. Your app never holds the API key — your server does. Pick a Layer by passing its domain slug in every correction request.
Issue a key for your project. Keys are hashed server-side and rate-limited per key.
Pass the domain slug — e.g. agronomy — in your POST /api/correct body.
Pipe ASR output from Whisper, Deepgram, browser speech, or anything that produces text.
