# Run quality checks on a string set

**Category:** [String Manager](https://help.totalctrl.app/hc/totalctrl/totalctrl-help-center/en-US/categories/strings)
**Updated:** 2026-10-04

## Why run checks

Quality checks catch localization problems before they reach users. Open a set and click **Analyze** to run them across every string and translation.
## Standard checks

- **Missing translation** — a target language has no value for a string.
- **Placeholder mismatch** — a translation is missing or adds variables (like `%s` or `{name}`) compared to the source. Flagged as an error.
- **Length warning** — a translation is unusually longer or shorter than the source, which can break layouts.
- **Untranslated content** — a translation that is identical to the source value.

## AI checks

A separate **AI analysis** runs as a background job and adds **spell check** and **grammar** findings. Start it from the set, then watch the job status; results appear alongside the standard findings when it finishes.
## Working with findings

Each finding has a severity (error, warning, or info) and points to the exact string and locale. You can dismiss a finding once you have handled or accepted it. Re-run the analysis any time to refresh results after edits.
## Find duplicate or similar wording

On a string's detail page, String Manager surfaces semantically **similar strings** in the same set using vector search, helping you reuse existing wording instead of creating near-duplicate keys.
