How to Use Transforms (Beta)

Available on: Mac and Windows (rolling out gradually). Polish is also available on iOS with a 10-word minimum.

Transforms rewrite text with AI — change tone, restructure, polish, or run your own custom prompts. Select text anywhere, press a shortcut, and Flow rewrites it in place.

Set up Transforms

Open the Transforms tab in Flow.
Click Try it out to launch the guided demo.
Highlight the sample text in the demo email editor, then press Opt+1 (Mac) or Win+Alt+1 (Windows) to run Polish.
Click Turn on Transforms, which appears only after a successful demo transform.

The opt-in toggle at the top of the Transforms tab controls whether the feature is active. Turning it off grays out the remaining settings and removes the Polish and View Diff shortcuts from your keyboard.

Note: Transform shortcuts don't register until you first visit the Transforms tab, click Try it out, or toggle Transforms on. This keeps international keyboard characters (ñ, ö) working normally before you opt in.

Default shortcuts

Polish: Opt+1 (Mac) / Win+Alt+1 (Windows).
Prompt Engineer: Opt+2 (Mac) / Win+Alt+2 (Windows).
View Diff: Opt+O (Mac) / Win+Alt+O (Windows).

Rebind View Diff from the View Diff shortcut pill at the top of the Transforms tab, or from Settings → Keyboard shortcuts. Rebind Polish and Prompt Engineer only from each transform's card on the Transforms tab; they don't appear in the Settings shortcuts dialog.

Configure a transform

You get up to 9 transform slots: slot 1 is fixed as Prompt Engineer, slots 2–9 are customizable, and a + Create your own card appears whenever fewer than 9 slots are configured. A separate Polish card at the top controls base Polish behavior, with 5 default toggle rules and up to 5 custom instructions of 50 words each.

Click any transform card to open its configuration modal.
Set a name (required for custom prompts).
Write a prompt describing what the transform should do.
Assign a keyboard shortcut.
Add writing samples (optional — see Add writing samples).

Warning: There are no Save or Cancel buttons. Changes auto-save, but a transform saves only once both a prompt and a keyboard shortcut are set. Closing the modal with a required field missing silently discards your changes.

Each modal's Reset button restores defaults for that transform; Reset Defaults on the main Transforms page resets all transform settings after a confirmation step.

Recording and changing shortcuts

Click the shortcut field to record a new key combination. Clicking Cancel (×), pressing Escape, or clicking outside the field exits recording without changing your existing shortcut; Escape does not close the modal.

To remove a shortcut, click the trash Remove shortcut button next to the pencil icon. It appears wherever shortcuts can be edited — the Transforms configure modal, Settings → Keyboard shortcuts, and other shortcut surfaces — when a binding is set and it isn't the action's only shortcut.

Add writing samples

Writing samples teach a transform what your finished writing should sound like, scoped to each individual prompt.

Limits: up to 5 samples per prompt, each 50–500 words. Only samples for the active prompt are sent.
Renaming and deleting: renaming a prompt carries its samples over; deleting or resetting a prompt removes them. Default Polish samples are always preserved.
Storage: samples sync between Mac and Windows. With Privacy Mode on (Share Usage Data off), writing samples and custom transform prompts stay local to that device and are not uploaded or synced. Under enterprise Zero Data Retention policies, samples are kept on-device.

FAQs

Why don't I see the Transforms tab in Flow?

Transforms is rolling out gradually on Mac and Windows. If the tab isn't there, your account hasn't received the rollout — there's no manual opt-in, and access expands over time.

Is Polish available on iOS?

Yes, with a 10-word minimum and 1000-word maximum. iOS Polish supports 5 built-in default instructions (Make text more concise, Replace words for clarity, Fix grammar spelling and punctuation, Add structure to improve readability, Match my existing tone and style) plus your own custom instructions. If you select text, only the selection is polished.

Can I get back to my original text after a transform?

In Scratchpad, the Version history dropdown steps back to any earlier save. Outside Scratchpad, the diff viewer's Undo button reverts the most recent transform.

Why didn't my new transform save?

A transform saves only when both a prompt and a keyboard shortcut are configured, plus a name for custom prompts. If any is missing when you close the modal, the changes are discarded.

I started recording a new shortcut by mistake. How do I cancel without losing my existing one?

Click Cancel (×) while recording, press Escape, or click outside the shortcut field. None of these change your existing shortcut.

Limitations and notes

Transforms is rolling out gradually on Mac and Windows. Up to 9 transform slots are available; slot 1 is fixed as Prompt Engineer.
The Polish bubble on the Flow bar is not shown to all users by default. Polish remains available via keyboard shortcut (Opt+1 / Win+Alt+1) and the right-click context menu, but Auto Apply After Dictation does not — with the bubble hidden, auto-polish cannot be turned on or off.
If you set up Wispr Flow for Notetaker only, the Transforms tab stays locked until you complete dictation setup. The lock is per-device — it may not appear after a reinstall or on a second device.
Desktop accepts 1–1000 words per transform. iOS Polish requires 10–1000 words.
Writing samples and the Translate to English re-polish option are not available on iOS.
Custom transform prompt slots sync between Mac and Windows unless Privacy Mode is on; iOS does not sync custom prompts or writing samples. Base Polish settings do sync.
Transform chips and the Transform bar are only available inside the Scratchpad — elsewhere, use the global keyboard shortcuts.
