Auto Translation Toggle Checklist

An auto translation toggle should be designed as a reading aid, not as a replacement for the source record. The fastest experience is often “translate immediately,” but the safest experience depends on whether the content is casual, operational, or high-risk.

First, classify the content type. Comments, short posts, onboarding tips, and low-stakes discovery pages can default to translated text. Payment rules, medical notes, legal terms, API errors, product settings, addresses, and source citations should keep the original visible or one tap away.

Second, preserve structure. Do not translate code blocks, IDs, version numbers, file paths, product names, currency symbols, measurements, or exact error strings unless the user explicitly asks. These are anchors for later action.

Third, show translation state. The user should know whether they are reading original text, machine translation, human translation, or a mixed view. A small label is enough, but hiding the state creates false confidence.

Fourth, make reversal cheap. If the button only says translate, add a clear return path: show original, compare, or pin original. Users should not need to reload the page to verify a phrase.

Finally, remember user intent. A traveler may want instant translation; a developer debugging an error may want original-first. The setting should adapt by content type and allow per-language exceptions.
