Over 200,000 businesses globally rely on DeepL to handle sensitive legal, technical, financial, and marketing communications. The platform spans three integrated product pillars: DeepL Translator, DeepL Write, and DeepL Voice. DeepL Translator handles instant text translation and full-document conversion—preserving exact typography, embedded images, and page layouts across PDF, Microsoft Word (.docx), PowerPoint (.pptx), and Excel (.xlsx) files up to 100 MB. Through its Customization Hub, teams enforce corporate terminology using Shared Glossaries, Translation Memory, and Shared Style Rule Lists, while interactive Clarify prompts resolve source-text ambiguities. DeepL Write Pro acts as an AI writing co-pilot that refines tone, fluency, and audience adaptation in real time, and DeepL Voice delivers live multilingual captions and speech-to-speech translation for virtual meetings and face-to-face conversations. DeepL offers a Free web and app tier capped at 50,000 characters and one 5 MB file per month, where submitted text may be used to train public models. For strict confidentiality—including immediate text deletion after translation, zero data training, ISO 27001 certification, and SOC 2 Type II compliance—users upgrade to DeepL Pro.

Instead of returning only the rigid synonym lists of a traditional dictionary, it accepts ordinary language as input — turns of phrase, slang, acronyms and partial thoughts — and proposes richer alternatives that fit the intent behind what you wrote. The app lives in a compact Mac window that can be pinned as a floating panel above other apps, so it stays within reach while you write in your editor, browser or chat window. Its results are presented in a leather-textured pane that can be customized across four visual styles, giving the tool a distinctive, desktop-native feel rather than a browser tab. A major part of version 2.0 is flexibility in how the AI runs. The app can use on-device Apple Intelligence models so lookups work offline without sending text anywhere, and it can also draw on fast cloud models such as Cerebras for quicker responses. Reviews praise the design and everyday usefulness while noting that the local model can feel slower than the cloud option, and that antonyms are not yet included. **Pricing & Plans:** Free. The app is listed on the Mac App Store at no cost, with no subscription required. Cloud model usage depends on the model provider arrangements built into the app. - **AI-powered synonym search:** Enter a single term, a phrase, an acronym or slang and get a diverse set of alternative words and similar expressions instead of a fixed dictionary list. - **On-device and cloud models:** Switch between local Apple Intelligence models for offline private lookups and faster cloud models such as Cerebras for lower-latency results. - **Pinnable floating window:** Keep the app as a small floating panel above your other windows so the right word is always a glance away while you write. - **Four customizable window styles:** Choose from multiple leather-textured skins to match the look of your desktop setup. - **Tiny footprint:** A roughly 14 MB download for macOS that starts quickly and stays out of the way. **Strengths:** Natural-language input handles phrases, slang, acronyms and idioms, not just single words; On-device Apple Intelligence support means lookups can work offline; Beautiful, minimal Mac-native interface with four customizable styles; Free to download with no subscription **Limitations:** Local on-device model can respond noticeably slower than cloud models; No dedicated antonyms function, a gap several reviewers have flagged; Requires a recent version of macOS to run [Profile (Markdown)](https://openaitools.app/tool/thesaurus.md) ## Frequently Asked Questions ### How do DeepL and Thesaurus – Powered by AI compare in monthly traffic?
