We’re excited to introduce Text Modifications using AI — a new set of tools that let you rewrite your existing translations using AI, right from the translation interface.
Whether you need to make a translation more formal for a legal document, more casual for a marketing campaign, or shorter to fit a UI constraint, you can now do it in a couple of clicks.
Rewrite Tabs: AI Alternatives at Your Fingertips
When you open a segment for editing, you’ll notice a new row of tabs above the suggestions panel: Suggestions, Formal, Casual, Technical, Shorter, Elaborate, and Other.
Click any preset tab and WebTranslateIt queries all your enabled AI engines (Gemini, Mistral) in parallel, giving you multiple alternative rewrites to choose from. Each result shows which engine produced it — just click one to paste it into your translation.

Results are cached as you work, so switching between tabs is instant. If you edit the translation text, the cache clears automatically and fresh results load when you return to a rewrite tab.
Custom Prompts You Can Save and Reuse
The Other tab opens a dropdown with your saved custom prompts. Choose Custom… to open a dialog where you can describe exactly how you want the text transformed — for example, “Use the informal ‘tu’ form instead of ‘vous’” or “Rephrase as a question.”
You can optionally save any custom prompt with a name. Saved prompts appear in both the Other dropdown and the right-click context menu, making them easy to reuse across segments.
AI Transform from the Context Menu
You don’t need to open a segment to transform it. Right-click on any segment and select AI Transform from the context menu, then pick a preset or enter a custom instruction.

Batch AI Transform
Need to adjust the tone of an entire file? AI Transform is available as a batch operation. Select your segments, choose AI Transform as the operation, pick a preset (or write a custom instruction), select the target language, and run it — all matching translations will be rewritten at once.

Available Presets
| Preset | What it does |
|---|---|
| Formal | Rewrites in a more formal register |
| Casual | Makes text more conversational and relaxed |
| Technical | Adjusts for a technical audience |
| Shorter | Condenses while preserving meaning |
| Elaborate | Expands with more detail |
| Custom | Your own transformation instruction |
