Questions, answered honestly.

No. Riffle analyzes and searches your recordings entirely on your device. Your audio, and everything Riffle derives from it, never leaves your computer. The only times Riffle uses the network are to check your license and to download its analysis models the first time you run it.

Yes. After the first-run setup — activating your license and downloading the analysis models once — Riffle works fully offline. Your license is cached as a signed record on your device, re-checking periodically. If it can't reach the licensing server, premium features keep working through a 14-day grace window, and your Library and files are never locked even past that.

No cloud, no sync, and no account or login inside the app. You buy or start a trial on the web and activate a license key in Riffle. That's it — Riffle is a single-user, local-first desktop app.

Riffle runs on macOS and Windows. There is no Linux build, and there is no mobile app. The installers are signed (and notarized on macOS) so they open without security warnings.

Riffle reads common audio formats including WAV, AIFF, FLAC, MP3, M4A/AAC, and OGG. Files it can't read are skipped and listed rather than stopping a scan.

No. Riffle reads your recordings where they are and never moves, copies, or changes your originals. Deleting a clip removes only Riffle's own record of it; sending the original to your OS trash is your explicit choice, and it stays recoverable. Quick-Capture recordings are saved into Riffle's own data folder.

Riffle keeps your Library — its derived data and settings — in a location it shows you, and you can relocate it. Deleting a clip removes its derived data, and you choose whether to also remove the source file.

Your Library and your files are never locked. Riffle gates premium features behind your subscription, not your own work — so if your subscription lapses, premium features pause while your recordings, organization, and files stay open to you.

Enter your email on the signup page and we send you a trial license key — no credit card. Activate the key in the app and you get the full Riffle for 14 days. Since there's no card on file, nothing charges automatically when the trial ends. The trial is tied to your email, so reinstalling doesn't reset it.

Riffle Pro is $4.99 per month and includes everything Riffle does. Cancel anytime.

Yes. Cancel whenever you like through the secure customer portal on the web. Your access continues until the end of the period you've already paid for, and your Library and files remain yours after you cancel.

Yes — Riffle comes with a 14-day money-back guarantee. On top of that, the free 14-day trial means most people can fully evaluate Riffle on their own recordings before they ever pay.

Checkout is handled securely by a Merchant of Record, which also handles sales tax and VAT for your region, so the right tax is applied automatically at purchase.

Find by Melody returns a short ranked list of best candidates with a confidence score, not a single guaranteed answer. It's designed for clear, mostly single-line melodies — a hummed or played riff — and matches them regardless of key or tempo. When nothing matches strongly, Riffle says so honestly and offers to search by description instead.

Yes. Quick-Capture lets you record a new clip inside Riffle from your chosen input. It's saved locally and analyzed right away, so it joins your searchable Library immediately.

Riffle drags out the actual audio file, so any DAW that accepts file drops works — drop a result onto your DAW's timeline or browser. You can also export a clip, or a trimmed selection, to WAV.

Riffle's interface is available in English, Spanish, French, German, Portuguese, and Japanese. Musical metadata such as key and tempo stays in its standard form across languages.

Riffle runs on macOS 11 (Big Sur) or later and Windows 10 or later (64-bit). The first run downloads analysis models — roughly 1 to 3 GB — stored on your device, so allow disk space for those plus your Library data. Analysis is faster on newer machines; it runs in the background and you can throttle or pause it.

It depends on how much audio you have and how fast your machine is — a large library can take a while on the first pass. It runs in the background newest-first, the app stays usable, clips become searchable as each one finishes, and you can pause anytime. After that, new recordings are analyzed as they arrive.
