What it brings on-device

No server in the loop. Every example below is computed right now, inside this page.

Small model. Serious accuracy.

Built for keyboards, chat apps and browsers where every kilobyte and millisecond counts.

Fits where big models can’t

Download size of the core and of core + dictionary versus a widely used open transliteration model.

How it works

  1. 1Generate

    A 4-bit character Transformer (the core) proposes spellings. With the dictionary pack attached it also searches a lexicon trie and consonant-skeleton matches, and adds acronym and spelling-variant candidates.

  2. 2Rerank

    A tiny learned reranker scores every candidate with model, lexicon and frequency features.

  3. 3Decide in context

    With the dictionary pack, a compact word-bigram language model chooses the best sentence, e.g. मैं vs में. Without it, each word keeps its top-ranked spelling.
