BlackSiren Full QWERTY keyboard typing a dialogue draft in the clean Try page
Type locally.Full QWERTY works without an account, network connection, or microphone permission. Voice and refinement stay one action away.

Local QWERTY needs no account or network

Voice starts only when you choose it

AI results stay tied to the active field

One keyboard, four ways to work

Type locally, dictate securely, clean up exact words, or ask for a broader rewrite without leaving the active field.

  1. Type

    Use complete local QWERTY

    Type letters, symbols, accents, and field-specific characters without signing in or sending text to BlackSiren. Shift, Caps Lock, repeated Backspace, and sentence capitalization work on the device.

  2. Speak

    Dictate with protected sessions

    Tap for hands-free recording or hold for push-to-talk. Signed-in requests verify that you are using the approved installed app. BlackSiren does not store your audio or transcript.

  3. Refine

    Polish the wording

    Select text for a focused cleanup. With no selection, BlackSiren can ask before polishing the full accessible field.

  4. Reshape

    Rewrite the message

    Rewrite can make larger wording and structure changes. Revert rewrite restores BlackSiren's short-lived snapshot while the same target remains current.

Illustrative Polish example

Draft

he said can you send the final draft she said yes ill send it after lunch

Polished

He said, “Can you send the final draft?” She said, “Yes, I’ll send it after lunch.”

Polish is designed to add quotation marks, capitalization, apostrophes, and sentence punctuation. Results can vary.

A keyboard that fits how you work

Follow Android automatically or choose from 6 light, 6 dark, and 10 transparent themes. The palette changes across QWERTY and voice layouts; control placement stays predictable.

Designed around boundaries

Local by default. Protected when connected.

QWERTY typing stays on the device. When you start Dictation, Polish, or Rewrite, BlackSiren sends only the audio or text needed for that action and does not retain the content.

    QWERTY text enters the active field without a BlackSiren account or backend request.
