Fix your writing
without sending it
anywhere.

Select text in any app. Press one shortcut. Fixly corrects it, rewrites the tone, or translates it — and puts it straight back where it was. Nothing you write ever leaves your computer.

$9.99 once · No subscription · No account · No data collected

Works in Mail · Slack · Gmail · Notion · Word · Docs · Linear · VS Code · Discord · Outlook · and anywhere else you can select text

Private by design

Other writing tools upload
every sentence you touch.
Fixly uploads nothing.

The whole thing runs locally on your own hardware. No API call, no server, no queue, no account, no analytics. Pull out the network cable and it works exactly the same — which means there is no copy of your draft anywhere to be breached, subpoenaed, retained, or trained on.

What leaves your computer

  • The text you selectNever
  • The rewritten resultNever
  • What you typeNever
  • Usage, crashes, analyticsNever
  • The app and its updatesDownload only
  • Your licence checkPurchase only

Those last two are the only network requests Fixly ever makes — and neither carries a single word of your text.

Works fully offline

On a plane, on a locked-down corporate network, in a SCIF. After setup, Fixly never needs the internet again.

Nothing to opt out of

There's no telemetry toggle because there's no telemetry. No privacy policy to trust, because there's no data.

Safe for real work

Client drafts, legal language, medical notes, unreleased product plans, source code. It never gets sent to a third party.

Three shortcuts

That's the whole app.

Fixly sits in your menu bar and stays out of the way until you call it.

⌃⌥P

Rewrite

Fix your own writing without leaving the text field. Pick a style once and it sticks.

  • Grammar fix
  • Polish
  • Formal
  • Casual
⌃⌥⇧P

Translate & Replace

Write in a language you're still learning, then swap your selection for a clean translation. The source language is detected for you.

⌃⌥⇧T

Quick Translate

Read what someone else wrote. The translation appears in a popup beside your selection — your original text is never touched.

16 languages — English, Spanish, French, German, Italian, Portuguese, Dutch, Russian, Chinese (Simplified), Japanese, Korean, Arabic, Hindi, Turkish, Polish, Ukrainian

Four styles

Same meaning. Your tone.

Every style is deliberately conservative — it edits your sentence, it doesn't write a new one.

Grammar fix

hi sam, i has reviewed the proposal and it look good.

Hi Sam, I have reviewed the proposal and it looks good.

Polish

I just wanted to basically say that I think the proposal is really quite clear.

The proposal is clear.

Formal

We can't ship because the API is acting up.

We are unable to ship because the API is experiencing issues.

Casual

Please be advised that the meeting was rescheduled to Friday.

The meeting was moved to Friday.

Getting started

Three minutes, once.

  1. 1

    Install and allow

    Fixly asks once for permission to read your selection and replace it. That permission stays on your machine.

  2. 2

    Finish the one-time setup

    A short guided download prepares everything Fixly needs to work offline from then on.

  3. 3

    Select, press, keep typing

    The setup walks you through every mode with your own text, so the first real one isn't a guess.

Details

Built to be trusted with a sentence.

It edits, it doesn't chat

No prompt box, no conversation, no “Sure! Here's your text.” You get the corrected text and nothing else.

Facts stay put

Names, numbers, dates, currency, URLs, emails, file paths, code, @mentions and #hashtags are protected before editing and restored after.

Structure survives

Paragraphs, line breaks, lists and Markdown come back exactly the way you wrote them.

Instructions aren't obeyed

A question or command inside your selection is treated as text to edit — never as something to answer.

Your shortcuts

All three are rebindable, with conflicts flagged as you record them.

Yours, not a service

No server to go down, no plan to expire. Signed updates arrive quietly in the background.

Questions

Everything you might ask.

Does it really work in every app?
Anywhere you can select and edit text — Mail, Slack, browsers, Notion, Word, your editor. Fixly asks for accessibility permission once so it can read your selection and replace it.
Do I need an internet connection?
Only to install the app, complete the one-time setup download, and validate your purchase. Every rewrite and translation after that happens offline, on your machine.
Is my writing used for training?
No. Your text is never transmitted anywhere, by anyone, for any purpose — so there is nothing to train on, sell, or leak.
Is it the same on Mac and Windows?
Yes — the same shortcuts, the same modes, the same fully local processing. One purchase covers both.
How fast is it?
A typical sentence comes back in about a second, without a network round-trip to wait on.
I got a new machine.
Open your activation link, choose Manage devices, and free the old slot. One purchase covers your next machine.

Better writing.
Nobody else reading it.
