Filename and exact-word content search, browsing, previews and manual tags. Pro tools need a Probe licence.
Start a seven-day Pro trial
You can deliberately start a seven-day Pro trial in the app. The trial and an active temporary promo grant the same rights as a Personal licence, including commercial use, for one person on up to 3 devices until they end. One trial is available per Windows user and machine; removing a key does not restart or restore it. Promo keys work offline through the displayed date, inclusive in UTC, and are distinct from perpetual gift and purchased Personal keys. Neither the trial nor the promo creates a subscription or an automatic payment. When either expires, the app returns to Free; documents, indexes and downloaded models stay. Pro actions require an active licence, trial or promo. Starting a trial and verifying a promo require no network connection and send nothing over the network. Model downloads are optional and require internet, compatible hardware and sufficient disk space.
