Lven Instant transcribes on your own device and types what you said — no rewrite, no word cap, works offline, ships on Linux, free.5–1 · 2 evenLven Instant vs. Windows voice typingWindows voice typing (Win+H) is free but uses Microsoft's online speech recognition. Lven Instant runs on-device — audio never uploaded, unlimited, and also on Linux and Android.5–2Lven Instant vs. DragonDragon is the professional Windows dictation suite with deep voice commands, sold through Nuance's sales team. Lven Instant is on-device dictation for Windows, Linux, and Android, measured about six times faster than you speak, and free.3–0 · 4 evenLven Instant vs. OpenWhisprOpenWhispr is free, MIT-licensed dictation with local models you download in the app. Lven Instant is free too, with a measured engine that sets itself up, an Android app, five devices on one account, and support.3–0 · 1 evenLven Instant vs. SuperDictateSuperDictate is a one-time-purchase on-device dictation app for Mac and Windows.

Ranked lists

Each list answers its question with a product and dates every fact about the alternatives. All ranked lists.

11 rankedThe best speech to text software in 2026, scoredFor live dictation, the best speech to text software in 2026 is Lven Instant: on-device, never rewrites your words, no usage cap, Windows, Linux and Android, measured about six times faster than you speak, and free. The ranking below also covers Mac and iPhone apps, voice control and meeting notes.8 rankedThe best voice to text app in 2026, on any deviceLven Instant is the best voice to text app when the words matter: on your own device, offline, no word cap, never rewrites, and one account covers Windows, Linux and Android. It is free. On a device too small for the model, Lven Cloud does the same job from our servers.7 rankedThe best transcriber app, by the job you need doneTo type your own speech into any app, the best transcriber is Lven Instant: on-device, offline, no word cap, never rewrites, free. To caption what others say: Google's Live Transcribe on Android and Live Captions in Windows 11, both on the device. To turn a recording into text: Otter.6 rankedThe best offline speech to text for WindowsLven Instant is the best offline speech to text for Windows: on the PC, offline after setup, no word cap, never rewrites, and the only app here with a published measurement — about six times faster than you speak at a 3.76% word error rate. It is free. The ranking below covers one-time purchases, open source and voice commands.3 rankedThe best dictation software for LinuxLinux is the platform most dictation apps skip: Wispr Flow, Typeless, Superwhisper, SuperDictate, Whisperstream and Dragon do not ship for it. Three do: Lven Instant, on-device, unlimited, measured, on X11 and Wayland, and free; Lven Cloud, server-side at $3.49 a month billed yearly; and OpenWhispr, free and open source if you manage Whisper models yourself.4 rankedThe best voice to text app for AndroidLven Instant is the best voice to text app for Android when the words matter: it transcribes on the phone, works offline, has no word cap, never rewrites, and types into WhatsApp, Gmail, Chrome or any field through a bubble. It is free. Lven Cloud does the same job on phones too small for the model.8 rankedWispr Flow alternatives, comparedThe best Wispr Flow alternative depends on why you left. The rewriting: Lven Instant types what you said. Privacy: Lven Instant transcribes on your device and uploads nothing. Price: Lven Instant is free; Lven Cloud is $3.49 a month billed yearly against $12. Linux or Android: Lven Instant ships on both.6 rankedThe best free PDF reader for Android without adsFolio PDF is the best free PDF reader for Android for reading, search and copy: no ads, no in-app purchases, no account, about 4 MB, and no Internet permission. For editing, signing or OCR, Adobe Acrobat Reader is a full suite with ads, purchases and an Adobe account; the rest sell in-app purchases.3 rankedThe best live speech translation app for Androidearslate is the best live translation app for Android: the translation plays into your earbuds while the other person keeps talking, with no account, free, and audio sent only to the AI provider on your own key. Google Translate's conversation mode is free but runs turn by turn on the screen through Google's cloud.
