Lifesaver.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.

A roughly 14 MB download for macOS that starts quickly and stays out of the way.
Thesaurus – Powered by AI rethinks the classic reference tool for the age of language models. 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.
