WriteAmp vs. the alternatives, honestly
WriteAmp is one way to stop retyping the same sentence. This page stacks it against the tools people actually reach for. Not to win. Just so you pick what fits. And yeah.
We’ll tell you where writeamp loses.
“I used CoTypist for a year. Switched because... I dunno, paying monthly for something that lives in my menu bar felt weird? WriteAmp just sits there. Same Tab thing,” says Jonas, a developer in Munich who still keeps both installed for now.
He paid once. Says he’ll probably forget about it. That’s kind of the goal.
At a glance
Prices are approximate public list prices and change; verify on each vendor's site. We intentionally don't name invented figures. “Open-source local” = KeyType, Cotabby, and TabType. Indie one-time options also exist (e.g. MacAutocomplete at $125 lifetime).

WriteAmp vs. CoTypist
CoTypist is the app that put this category on the map, polished, well-liked, and the reason most people know what Mac autocomplete is. If you like CoTypist, you'll feel at home in WriteAmp: same ghost text, same Tab key, same every-app reach, all on-device.
The differences that matter: CoTypist is a subscription, $6/month for one Mac, $9/month for three, billed annually, and its free tier stops suggesting after 100 completed words a day. WriteAmp is $29 once, with unlimited suggestions on up to three Macs; a single year of CoTypist Plus costs more than two WriteAmp licenses (more on the one-time pricing →). WriteAmp also publishes its latency and quality benchmarks, shows you the exact phrases personalization has stored, and labels each language's real support level.
Where CoTypist wins: it's the most mature product in the category, its Pro tier ships a curated model catalog plus Labs features like word alternatives, and the free tier is genuinely free if 100 words a day covers you.
Pick CoTypist if…
You want the incumbent, you're happy on a monthly plan, or its free 100-words-a-day tier is enough for how much you type.Pick WriteAmp if…
You want the same habit without a subscription or a daily word cap, personalization receipts you can read and wipe, and the numbers published.WriteAmp vs. open-source alternatives (KeyType, Cotabby, TabType)
There are free, open-source apps doing the same job, KeyType, Cotabby, and TabType all run local models, suggest ghost text system-wide, and send nothing to a server. We respect these projects; a rising tide is good for the category.
The honest trade is maturity: Cotabby is in beta, TabType is an explicit alpha (“expect rough edges”), and app coverage varies. WriteAmp is notarized by Apple, production-hardened across the apps people actually type in, ships 8 languages with honest labels, and includes encrypted personalization you can audit. The $29 buys the boring parts, compatibility work, benchmarks, support, and maintenance, not the idea.
If cost is the constraint, genuinely: try the open-source options first. Then run WriteAmp's 30-day trial next to them and pick with your own hands.
Pick open-source if…
$29 is too much, you enjoy tinkering and filing issues, or you want to read and modify the code you type through.Pick WriteAmp if…
You want it to just work in every app tomorrow, notarized and supported, with receipts for what it learns.WriteAmp vs. Grammarly
Grammarly is a mature grammar and clarity assistant. Its strengths are real: deep grammar checking, a polished editor-side experience in browsers, and a well-known brand. WriteAmp does not try to be a grammar checker.
Pick Grammarly if…
You want grammar corrections and style suggestions at sentence level, in browsers and docs, and you're comfortable with the privacy trade of sending drafts to the cloud. It's the best-known tool for that job.Pick WriteAmp if…
You want the next-words autocomplete habit in every app, Mail, Slack, terminals, code editors, with nothing leaving the Mac, a one-time price, and personalization you can read and delete.WriteAmp vs. TextExpander
TextExpander is the best tool for exact, repeated boilerplate, signatures, addresses, standard replies, triggered by an abbreviation you choose. That's something autocomplete is deliberately not.
Pick TextExpander if…
You type the same verbatim strings over and over and want them byte-identical every time. For known boilerplate, an expander is more reliable than any predictive model.Pick WriteAmp if…
Your repetitions are near-repeats that vary, "Thanks for the quick turnaround…", "Following up on…", where a model suggests based on how you actually write. Most everyday sentences aren't fixed boilerplate.WriteAmp vs. Raycast AI
Raycast AI is a capable assistant, but it lives inside the Raycast launcher, a different place than the field you're typing in. It's cloud-based and subscription-priced.
Pick Raycast if…
You already live in Raycast and want a general-purpose AI assistant (summary, rewrite, ask) alongside your launcher. Different job.Pick WriteAmp if…
You want suggestions at the caret in the app you're already using, with no context switch, and you want your writing to stay on-device.WriteAmp vs. Apple Intelligence & macOS's built-in predictions
macOS ships free inline predictions in some Apple apps, and on macOS 26+ Apple Intelligence adds an on-device writing engine. Both are private and free, but coverage is patchy and there's no system-wide Tab-to-accept habit across third-party apps.
Pick Apple / built-in if…
You mostly write in Apple's own apps, want the free bundled option, and don't need per-app learning or cross-app reach.Pick WriteAmp if…
You want the same ghost-text habit in Mail and Slack and a browser and VS Code, plus learning you can inspect. Note: on supported macOS 26+ Macs, WriteAmp can itself route through Apple's on-device model, so you can get the WriteAmp habit with the Apple engine underneath. And that mode stays free even after the trial ends.Try it yourself
