01
See words as you speak
The overlay shows Gemini's running transcript, so you can notice the wrong language, microphone, or name before text is inserted.
Real-time voice typing for Windows
Speak naturally.
Keep your flow.
Hold a key, speak, and release. SenFlow shows the transcript while you talk, then types the finished text into the app you are already using.
Live transcription
Works in any text field
No GPU required
A clear live transcript while speaking, followed by a brief finalisation state.

Designed for daily work
Fast enough to become invisible
SenFlow keeps the interaction short and predictable, while the controls you need remain available from the tray and Settings window.
02
Finish without a long wait
Audio streams during speech. Releasing the key only waits for the final words rather than uploading the entire recording.
03
Recover from interruptions
A short pre-roll captures clipped starts, natural pause handling protects word endings, and failed recordings remain available for retry.
04
Edit selected text by voice
Select text and dictate an instruction to fix grammar, translate, summarise, or rewrite it directly in place.
05
Keep a searchable history
Review saved dictations, batch-transcribe audio, identify meeting speakers, and export SRT or WebVTT captions.
06
Use only what you need
The live interpreter, output styles, custom vocabulary, sound cues, and overlay themes are optional and stay out of the primary voice typing path.

One simple workflow
From speech to text in three steps
Right Ctrl remains the primary shortcut. An optional F13 key supports dedicated voice hardware.
01
Place the cursor
Open any normal Windows text field where you want the words to appear.
02
Hold and speak
Use Right Ctrl or the configured hardware key. Watch the live transcript as you talk.
03
Release to insert
SenFlow finalises the transcript and types it at the current cursor position.
Before you install
SenFlow transcribes with Google's Gemini API, so while you hold the key your audio is sent to Google. It needs an API key and internet access, and there is no offline mode. Google's Gemini API terms state that on the free tier Google may use submitted content, including dictation, to improve their products. Paid-service protections and regional exceptions are described in those terms. Your Google account and billing determine which terms apply. Read the Privacy Policy before dictating sensitive information.
Controls
Shortcuts that stay out of the way
The common actions are available from the keyboard. Everything else remains in the tray menu and Settings window.

Installation
A small, per-user Windows app
The installer does not require an administrator prompt. On first launch, SenFlow validates your Gemini API key before saving it.
- Windows 10 or 11, 64-bit.
- A microphone. SenFlow can follow the Windows default device and return to a preferred device when it reconnects.
- A Gemini API key. Create one through Google AI Studio.
- An internet connection. Transcription is cloud based.
- No GPU or model download. The installer contains everything the desktop app needs.
Operational details
Clear about what it stores
Successful transcripts are saved locally so they can be searched and recovered. Usage counters also remain on your computer.
- Dictation history:
%APPDATA%\SenFlow\scratchpad.db - Preferences:
%APPDATA%\SenFlow\config.toml - History retention: older non-favourites are pruned after 2,000 entries by default; favourites remain until deleted.
- Language support: more than 85 languages with optional automatic detection.
- Elevated apps: Windows blocks text injection into an administrator-level app unless SenFlow runs at the same level.
