SpellBound
SpellBound brings AI writing completion, rewriting, and grammar fixes to any text field on macOS.
Worth the money only if two things are true: you write all day on a Mac, and your drafts can't leave the machine. Offline mode and local processing are the actual product here. If neither applies, Grammarly or ProWritingAid cover more surface for the same monthly spend — just with a cloud round trip.

Skip SpellBound if you need one writing assistant that works across Mac, Windows, and the browser for a team — it is a single-user, macOS-only app with no shared documents or collaborative editing.
The annual plan is $144/yr, which only beats the $19/mo month-to-month rate if you actually stay on the tool for the full year — cancel at month three and you've overpaid versus monthly.
At $19/mo month-to-month or $144/yr (about $12/mo billed annually), SpellBound sits in the same bracket as Grammarly Premium and ProWritingAid. The premium is for Mac-native delivery and local processing, not for more features — if privacy isn't a hard requirement, the cheaper cross-platform options deliver more surface area per dollar.

What is SpellBound?
SpellBound — SpellBound brings AI writing completion, rewriting, and grammar fixes to any text field on macOS. Best for Mac writers producing long-form drafts who want AI help without leaving their editor, Professionals under NDA or internal data rules who can't send drafts to a cloud service, Students on macOS who want real-time grammar and style help while writing. Plans from $144/yr.
SpellBound is a native macOS AI writing assistant aimed at people who type for a living and don't want to bounce into a separate chat window to get help with a sentence. It injects context-aware completions, paraphrasing, rewriting, and inline grammar and style fixes into whatever text field has focus — Mail, Outlook for Mac, Google Docs, Notion, Ulysses, Slack, or Messages. The pitch is one keystroke away, no app switch, no copy-paste round trip. The client list is Mac writers, students, and knowledge workers who produce long-form text across several apps in a single day. Targeted features include custom tone profiles tuned to your own voice, a searchable history of past writing across apps, a floating assistant that trails your cursor, keyboard shortcuts for quick completions and rewrites, multiple AI model support, and multi-language output. The privacy angle is the second sales argument. Offline mode and local data processing let drafts stay on the machine instead of a third-party cloud, which is the feature that matters most to those working under NDA or internal data-handling rules. Scope is narrow and the profile says so. No team workspace, no collaborative review, no browser version, no Windows or Linux build. It sits against Grammarly Premium and ProWritingAid on price, and competes on native Mac injection and local processing rather than cross-platform sync or the wider suggestion coverage a mainstream grammar checker carries.

Behind the verdict
The buying question for SpellBound isn't 'is it good at grammar' — it's 'do I need writing help in places Grammarly doesn't reach.' If your day runs through Apple Mail, Ulysses, and a couple of internal Mac apps, spellBound's system-wide injection is the point. If you live in Google Docs in a browser tab, a browser-native tool gives you the same suggestions with less friction and zero install. We'd reach for this when a draft can't go to a cloud service and you still want completions and rewrites at the cursor. Offline mode plus local processing is a specific combination, and it's rarer than the marketing around most writing tools suggests. Custom tone profiles and searchable writing history are nice for people who write the same kind of document repeatedly. Where it bites: the scope is one user. No team workspace, no review comments, no collaborative editing. Content teams that pass drafts around won't get what they need, and Windows or Linux colleagues are simply out. Pricing sits at $19/mo month-to-month, or $144/yr (roughly $12/mo billed annually). That's the same bracket as Grammarly Premium. You're paying for Mac-native injection and on-machine processing, not for a bigger suggestion engine or cross-device sync. One practical caveat: the vendor site returned a Cloudflare 521 host error on our last check, so we couldn't independently reconfirm current tiers. Confirm price and whether a trial exists on the site before you subscribe. Our figures come from the profile on file, not this month's page. Closest alternative if privacy isn't the driver: Grammarly Premium — broader suggestion coverage, browser and desktop, team plans. If it is: check whether your employer already supplies a local-processing tool before paying out of pocket.

- ↗To Grammarly: export your current drafts from your Mac editors, switch to the browser extension, and you gain cross-platform support and team features you don't get in SpellBound.
- ↗To ProWritingAid: import your documents into its editor or integrations for a deeper style and readability analysis pass than SpellBound's inline corrections.
