@fetchitai/engine

Deterministic text cleanup and AI-writing heuristics that run entirely in your process. Your users text never leaves it.

import { clean, applyEdits, toUtf16Offsets } from "@fetchitai/engine";

const result = clean(aiDraft);
// result.edits    auto-safe fixes (invisible chars, look-alike spaces, dashes)
// result.flags    AI-associated wording, for a human to accept or reject
// result.aiReport heuristic score

// apply what a human accepted:
const finalText = applyEdits(aiDraft, accepted, result.edits);

Offsets are code points. For DOM highlighting, convert with toUtf16Offsets(result, inputText). See the repository README for the full CleanResult contract.
