Fixkey
Fixkey is a native macOS writing assistant that rewrites, corrects, translates and dictates text inside any Mac app. A keyboard shortcut replaces your draft with polished writing, so daily writers never leave the window they are already in.
What is Fixkey?
Fixkey is a native macOS writing assistant: a lightweight app written specifically for macOS that adds an AI layer to every window you already type in, instead of adding one more tab to visit. The site condenses the idea into a line—"Type or speak, and Fixkey transforms it into polished writing instantly. Works anywhere on your Mac." The text stays in the app you are working in, with no copying, no pasting and no context switch.
Two shortcuts carry most of the product. Option+S, called the Quickfixer, improves the sentence you are on or whatever you have selected, with no manual selection step. Cmd+Shift+Space opens a popup fixer for paragraphs and longer content. A third, Option+C, converts a line of pinyin into Chinese characters, a workflow Fixkey gives its own page and where it claims a 200% gain in typing speed. All shortcuts are presented as fully customisable.
Dictation sits beside typing: real-time transcription with automatic punctuation and formatting, spoken commands to build structure hands-free, and Voice Polish, which cleans up dictated text automatically. Translation is announced at 180+ languages on the homepage and the customer support page, but at 200+ in the Benefits block and on the ChatGPT comparison page—the site does not agree with itself. Customisation runs deeper than most rivals: a Prompt Editor and a Prompt Picker for your own prompts, plus a personal dictionary you add words to.
The claimed numbers are aggressive: responses under 200 ms, millisecond edits, 80% faster than Notion AI, 60% less response time in customer support, writing 3x faster by voice, and 20,000+ people who improved their writing with Fixkey last year. Against classic checkers, Fixkey argues that it treats a whole sentence or paragraph rather than correcting word by word.
Compatible apps shown on the homepage include Apple Notes, Discord, LinkedIn, Notion, Obsidian, Signal, Slack, Telegram and WhatsApp; Gmail, Microsoft Word, Zendesk and Intercom are cited elsewhere. The publisher is Headstart Ventures UG, in Berlin, and the footer reads Made with love in Europe. Distribution is a direct .dmg download rather than a Mac App Store listing, with an account created on the app subdomain. Product Hunt named it Product of the Day, and t3n, Cult of Mac and Ben's Bites have covered it.

When to use Fixkey / When not to
A quick filter to help you decide if Fixkey is the right fit.
When to use Fixkey
- Mac users who write all day inside other people's apps—email, chat, notes, support tickets—and want the AI where the cursor already is, driven by a shortcut rather than a separate window.
- Non-native English speakers polishing everyday professional messages, an audience Fixkey addresses head-on with its promise to make you sound sharp even when it is not your native language.
- Customer support agents working in Zendesk, Intercom or Gmail, the use case Fixkey builds a dedicated page around, claiming a 60% cut in response time across email and live chat.
- People who would rather speak than type: real-time transcription with automatic punctuation, voice commands for structure, Voice Polish on the result, and 180+ languages announced for voice.
- Pinyin typists producing Chinese characters, converted line by line with Option+C on a page Fixkey dedicates to the workflow, where it claims a 200% gain in typing speed.
When not to use Fixkey
- Anyone who is not on a Mac. There is no Windows, Linux, iOS, Android or web version, and no browser extension: macOS is the only supported platform.
- Buyers who have to clear a legal or procurement review. No terms of service are published at all, no DPA is offered, no subprocessor list exists, no security certification such as SOC 2 or ISO is displayed, and nothing is stated about whether customer data trains models.
- Developers who want to call the engine from their own product. Fixkey exposes no public API and publishes no developer documentation.
- Teams that need central administration, seat-based billing, shared prompt libraries or usage reporting. Nothing of the kind appears anywhere on the site; the single plan is sold to individuals.
- People looking for a permanently free tool. There is a 14-day trial and one paid tier, and no free plan behind it.
How to use Fixkey
A typical end-to-end flow, from setup to results.
- Download the app through the Download for Mac button repeated on every page of the site
- Open the .dmg and install Fixkey on your Mac; there is no Mac App Store listing
- Create an account on the Fixkey app subdomain, with Google or with an email address
- Start the 14-day free trial; no credit card is requested at this stage
- Write or dictate as usual, inside whichever macOS application you already work in
- Press Option+S to improve the sentence you are on, or whatever text you have selected
- Press Cmd+Shift+Space to open the popup fixer on a full paragraph or longer passage
- Press Option+C to convert a line of pinyin into Chinese characters
- Make it yours: build prompts in the Prompt Editor, add words to the personal dictionary, remap the shortcuts; in Obsidian, place the cursor on a bullet and press Option+S, with Markdown, dash, asterisk and numbered lists all supported
- Expect to work the rest out alone: the site publishes no installation guide, no documentation, no help centre and no system requirements, neither a minimum macOS version nor the accessibility permissions this kind of app normally needs
Pros & Cons
Pros
- Works inside the app you are already in: no tab to switch to, no copy-paste, no second window to manage
- Very low claimed latency, with edits announced under 200 ms and described as millisecond responses
- Native macOS build, presented as lightweight and written specifically for the system rather than ported to it
- Voice and text in one tool, with real-time transcription, automatic punctuation and Voice Polish on the dictated result
- Broad announced language coverage, from 180+ to 200+ languages, plus a dedicated pinyin-to-Chinese path
- Genuine customisation: your own prompts, your own shortcuts, your own dictionary
- Low price for an AI subscription at 48 USD a year, roughly 4 USD a month, with a 14-day trial that asks for no credit card, an EU publisher and data announced as stored in Europe
Cons
- macOS only: no Windows, no Linux, no mobile app and no web version, so the tool follows the machine rather than the user
- No terms of service are published at all. The Terms of Service link on the sign-up page returns a 404, which means the sign-up flow asks you to accept a document that does not exist
- A four-paragraph privacy policy with no effective date, no retention period, no data subject rights, no legal basis and no processor list, while PostHog analytics and a Reddit advertising pixel load on every page reviewed without being declared in it
- Nothing is said about whether customer data is used to train models, in either direction, and no model provider or security certification is named anywhere
- The site contradicts itself on commercial points: 180+ languages on some pages against 200+ on others, and a One-time purchase, Pay once, use everywhere pitch on the Notion comparison page against the monthly or annual subscription actually sold on the pricing page
- No permanently free plan, and no support email: the only address published anywhere is robert@fixkey.ai, in the imprint, where it also serves the affiliate programme
- No documentation, no help centre, no changelog and no system requirements, no robots.txt and no sitemap.xml; the homepage's Hacker News link is still a template and the footer copyright is frozen at 2025
Pricing & Plans
Fixkey offers no permanently free plan. Access is sold through a single paid tier, Fixkey Pro, priced at 48 USD per year on annual billing, which works out at roughly 4 USD per month, or at 7 USD per month on monthly billing, amounting to 84 USD over twelve months. The annual commitment therefore saves 36 USD, close to 43%. The monthly figure is not displayed in the static pricing page and is readable only in that page's JavaScript bundle. A 14-day free trial is offered without a credit card. Payment is processed by Stripe. No team, seat-based or enterprise pricing is published, no refund policy is stated, and all prices are quoted in US dollars, with no euro price despite the German publisher.

Data, GDPR & hosting
A consolidated view of how Fixkey handles your data.
GDPR overview
Fixkey is published by Headstart Ventures UG, a German company registered under HRB 199226 and managed by Niklas Jansen, with German law and the Amtsgericht Berlin named in the imprint. The publisher is therefore established inside the European Union, and no Article 27 representative is required or designated. Compliance is claimed in general terms only: data is securely handled and processed under EU privacy regulations, and the company says it complies with EU data protection regulations. The GDPR is never named, and no article is cited. Measured against a complete notice, the policy has no effective date or last-update date, no processing purposes, no legal bases, no retention periods, no processor or subprocessor list, no data subject rights or procedure to exercise them, no data protection officer, no privacy email, no DPA offer and no minimum age. Compliance here is asserted, not demonstrated.
Who owns the data?
Neither document settles this, because only one of them exists. The four-paragraph privacy policy never addresses ownership of accounts, dictations or the text Fixkey rewrites; it claims no licence over that content, but grants the user no assurance either. No terms of service fill the gap: the Terms of Service link on the sign-up page returns a 404. The policy is equally silent on data subject rights—access, erasure, portability, objection—and on any procedure for exercising them. The only privacy channel published is a postal address, Headstart Ventures UG, Gärtnerstr. 3, 10245 Berlin, Germany: no email, no form, no named contact. On ownership, Fixkey's documentation says nothing at all.
Reuse rights
Because no terms of service exist, nothing published restricts what a user does with the text Fixkey produces: no licence grant, no attribution clause, no limit on commercial use appears anywhere. Read strictly, that is an absence of rules rather than a granted permission. On Fixkey's own side, the privacy policy says only that all data is processed and stored on secure servers in Europe, under strict security protocols and enterprise-level monitoring. It enumerates no processing purpose, cites no legal basis, and names no language model provider even though the product runs on LLMs it describes as advanced. Three third parties are nevertheless involved and none is declared: PostHog analytics and a Reddit advertising pixel load on all fifteen pages reviewed, and payment runs through Stripe. The gap between what is declared and what actually loads is the notable finding here.
Data retention & training
Hosting summary
Fixkey makes a single statement about hosting: all data is processed and stored on its secure servers in Europe, under strict security protocols and in compliance with EU data protection rules. That is the whole of it. No country is named, no region is specified, no infrastructure provider is cited and no hosting certification such as ISO 27001, SOC 2 or C5 is displayed. Nothing is published about where LLM inference takes place, which for this product is the part that actually sees the user's text. The publisher is established in Germany and the footer reads Made with love in Europe, which supports the claim without documenting it. One nuance is worth recording: the website itself is served by Vercel, on the anycast address 76.76.21.21, geolocated in the United States on an Amazon autonomous system. That concerns the marketing site, not the processing of user data, and the two should not be confused, but it is the only hosting fact that can be verified independently. Everything else rests on a single unsourced sentence.
Things to keep in mind
Risks and trade-offs to weigh before adopting Fixkey.
- There are no terms of service. The Terms of Service link on the sign-up page points to /terms, which returns a 404, so the account you create is governed by a contract that was never published. Nothing defines what either side owes the other, what happens to your content, or what recourse you have if the service stops.
- The privacy policy is four paragraphs long: no effective date, no retention period, no data subject rights and no procedure to exercise them, no legal basis, no processor list. Meanwhile PostHog analytics and a Reddit advertising pixel load on all fifteen pages reviewed, and payment runs through Stripe, none of them mentioned in that policy.
- Nothing is said about training models on customer data, in either direction, no opt-out is documented, no model provider is named and no security certification is displayed. Anyone pasting or dictating confidential text into a Mac window is relying on silence rather than on a commitment.
- The servers are announced as being in Europe, but no country, provider or hosting certification is named, and nothing is published about where LLM inference actually happens. The site itself is served from a Vercel anycast address geolocated in the United States. That is website hosting, distinct from data processing, but the gap deserves a question before signing.
- The site contradicts itself on two points a buyer would rely on: 180+ against 200+ languages depending on the page, and a One-time purchase, Pay once, use everywhere pitch on the Notion comparison page against the monthly or annual subscription actually billed. The 7 USD monthly price is also invisible in the page source and readable only in the JavaScript bundle.
- The product is designed to remove all friction from rewriting, which is exactly what makes over-reliance easy: when every sentence can be improved by reflex, the habit of drafting, and then of judging your own draft, erodes quietly. That risk falls hardest on the non-native speakers the site targets by name, who may end up with a voice that is fluent, uniform and no longer theirs.
- Disclosure and freshness are weak. The Founder of Blinkist testimonial comes from the managing director of the publishing company, without that link being disclosed; the MacSparky article cited as press coverage is flagged as sponsored in its own URL; the Hacker News link is still a template; the imprint names the Amtsgericht Berlin where the register gives the Amtsgericht Charlottenburg for HRB 199226 B; the footer copyright is stuck at 2025 and a banner is dated Apr 1 with no year. No support email and no minimum age are published.
Setup & Integrations
Technical difficulty
Very low. Setting Fixkey up is a consumer install: download the .dmg, install it on a Mac, create an account with Google or an email address, and start the 14-day trial. There is no configuration, no API key, no deployment and nothing to connect. Day-to-day use rests on three shortcuts, Option+S, Cmd+Shift+Space and Option+C. The only real friction is documentary: the site publishes no installation guide, no help centre and no system requirements, so neither the minimum macOS version nor the accessibility permissions such an app usually needs are stated anywhere.

Should you pick Fixkey?
Fixkey makes a narrow, legible promise and keeps it: it is not one more AI app to open, but a writing layer bolted onto macOS itself. Press Option+S and the sentence under your cursor comes back cleaner, in the window you were already in. Dictation, translation, custom prompts and a personal dictionary sit behind the same reflex. At 48 USD a year, roughly 4 USD a month, the price-to-scope ratio is favourable against most AI subscriptions, and a 14-day trial without a credit card makes the tool easy to judge on your own writing rather than on its marketing.
The reservations are not about the product but about everything around it. No terms of service exist: the link on the sign-up page returns a 404, so users are asked to accept a contract that was never published. The privacy policy runs to four paragraphs with no effective date, no retention rule, no data subject rights and no processor list, while PostHog and a Reddit advertising pixel load on every page without appearing in it. Nothing is said about training models on customer data, in either direction.
The site also contradicts itself where it matters commercially: 180+ languages against 200+, and a One-time purchase pitch on one comparison page against the subscription actually billed on another. Add a copyright frozen at 2025, a Hacker News link left as a template, and a change of ownership claimed by the creator off-site but never announced on it.
The verdict splits cleanly. As a daily tool for a Mac user who writes constantly, Fixkey is well built, fast and cheap. As a purchase that has to survive a legal review, it is not ready: the product is well ahead of its paperwork.
