Grammarly Keyboard Alternatives

Best for: Lightweight multilingual Android keyboard.

Multiling O Keyboard is a lightweight Android keyboard aimed at multilingual typing, custom layouts, gestures, themes, and compact installation size. It can be useful for users whose priority is language coverage and layout flexibility, but it should be reviewed for maintenance status and device compatibility.

Pricing: Google Play listing indicates a free app; current maintenance and in-app terms should be verified.

Best for: Personalized Android keyboard with AI and theme features.

ai.type is an Android keyboard focused on personalization, themes, prediction, emoji, and local AI claims in its current store listing. Because the brand has historical security and billing-abuse reports, it should be manually reviewed before being promoted as a safe Grammarly Keyboard alternative.

Pricing: Google Play listing indicates free availability; current in-app purchases should be checked manually.

Best for: Predictive mobile keyboard with swipe typing and themes.

Microsoft SwiftKey is a customizable mobile keyboard for users who mainly want fast typing, prediction, swipe input, themes, and multilingual support rather than Grammarly-style writing coaching. It can be a practical alternative when the goal is replacing the default keyboard, but it is not a full grammar editor.

Pricing: Free to download; Microsoft account features and service behavior should be checked in current support pages.

Best for: Default-style Google keyboard for fast mobile typing.

Gboard is Google’s mobile keyboard for Android and iOS, with glide typing, voice typing, handwriting, emoji search, GIF support, and language tools. It suits users who want a polished everyday keyboard, but it is closer to a typing utility than a dedicated grammar and tone assistant.

Pricing: Free app; availability and features vary by platform and device.

Best for: Open-source Android keyboard with language packs.

AnySoftKeyboard is an open-source Android keyboard focused on customization, language packs, themes, gesture typing, and privacy-oriented input. It is a stronger fit for users who want a community-maintained keyboard than for users who need Grammarly-style AI rewriting or advanced grammar feedback.

Pricing: Free and open source; confirm app-store build freshness before recommending to managed-device users.

Best for: Legacy predictive keyboard with significant safety review needs.

TouchPal was a long-running mobile keyboard known for prediction, swipe typing, emoji features, and themes. Because the product has a history of adware and Play Store removal reports, it should not be presented as a routine Grammarly Keyboard alternative without a fresh safety and availability review.

Pricing: Current official pricing and official distribution could not be confidently verified.

Best for: Keyboard technology and SDK platform with prediction features.

Fleksy is now positioned mainly around virtual keyboard technology, SDKs, prediction, swipe input, and white-label keyboard experiences. It may still be relevant for users comparing typing engines, but consumer app availability should be checked carefully before listing it as a direct Grammarly Keyboard replacement.

Pricing: SDK and commercial terms should be verified with Fleksy; consumer app availability may vary.

Best for: Legacy customizable Android keyboard with adaptive themes.

Chrooma Keyboard was an Android keyboard known for adaptive colors, themes, gestures, emoji support, and prediction. Recent official availability was not confidently verified, so it should be treated as a legacy candidate rather than a primary recommendation until the official source and update status are checked.

Pricing: Current official pricing and availability are unclear.

Best for: Linux accessibility on-screen keyboard.

Onboard is a Linux on-screen keyboard designed for users who cannot easily use a physical keyboard, including tablet and accessibility workflows. It is not a Grammarly-like writing assistant, but it can be relevant for Linux users comparing input methods rather than grammar correction tools.

Pricing: Free and open source.

Best for: Minimal Android keyboard with few permissions.

Simple Keyboard is a minimal open-source Android keyboard for users who want only basic typing, small size, minimal permissions, and no ads. It deliberately omits many convenience features such as emoji, GIFs, spell checking, and swipe typing, so it is best positioned as a privacy/minimalism option.

Pricing: Free and open source.

Best for: Portable Windows on-screen keyboard launcher.

On-Screen Keyboard Portable wraps the Windows built-in on-screen keyboard for portable use from the PortableApps.com platform. It is an accessibility and fallback input utility, not a mobile keyboard or grammar checker, so it should be grouped separately from Grammarly-style writing tools.

Pricing: Free PortableApps utility.

Best for: Legacy GIF keyboard concept.

PopKey was a GIF keyboard concept for sending animated GIFs from mobile conversations. Current official availability is unclear, and it does not overlap much with Grammarly’s grammar, tone, or writing-assistant features. Consider replacing it with a maintained GIF keyboard if this category is still needed.

Pricing: Current pricing and official availability could not be verified.

Best for: Compact predictive keyboard for small screens.

Minuum Keyboard is a compact keyboard concept built around a tiny, predictive layout for phones and other small screens. The official site is still reachable, but current app-store availability and maintenance status should be checked before treating it as an active Grammarly Keyboard alternative.

Pricing: Current pricing and availability are unclear.

Best for: Multilingual grammar and style checking.

LanguageTool is a multilingual grammar, spelling, and style checker available through web, browser, desktop, and developer options. It is a closer Grammarly alternative than most keyboard apps when the user’s priority is writing quality rather than keyboard layout or swipe typing.

Pricing: Free and Premium options exist; browser-extension availability and limits should be verified.

Best for: English grammar, rephrase, and writing assistant.

Ginger is an AI-powered writing assistant for grammar, spelling, punctuation, rephrasing, synonyms, and style improvement. It is a strong comparison point for users who want English writing help across browsers, desktop tools, and mobile apps rather than just a replacement keyboard.

Pricing: Free entry points exist; verify current premium terms on Ginger pages and app stores.

Best for: Grammar and spelling help for Microsoft workflows.

Microsoft Editor provides spelling, grammar, and style suggestions in Microsoft 365 web apps and through browser workflows. It is not a phone keyboard, but it is relevant for users who want a Grammarly alternative for web writing, Word, Outlook, and Microsoft account-based workflows.

Pricing: Basic features are free; advanced features may require Microsoft 365.

Best for: AI keyboard for grammar, tone, and paraphrasing.

CleverType is an AI keyboard that offers grammar correction, paraphrasing, translation, tone changes, and writing assistants directly from the keyboard. It is worth comparing for users who specifically want mobile AI writing help rather than a general predictive keyboard.

Pricing: Free access is advertised; verify subscription and in-app purchase details before publishing.

Best for: Privacy-oriented mobile keyboard with large-key layout.

Typewise is a mobile keyboard for Android and iPhone that emphasizes fewer typos, large keys, customization, and privacy-oriented typing. It is more of a keyboard replacement than a grammar editor, but it can fit users who want a different typing experience from Grammarly Keyboard.

Pricing: Free app availability exists; confirm Pro or subscription terms on current listings.

Best for: Offline open-source Android keyboard.

HeliBoard is a privacy-conscious open-source Android keyboard based on AOSP/OpenBoard. It does not use internet permission, which makes it relevant for users who prefer offline typing and transparency over cloud grammar checking or generative AI features.

Pricing: Free and open source.

Best for: Customizable open-source Android keyboard.

FlorisBoard is a free and open-source Android keyboard focused on modern design, customization, and privacy. It is still described as beta, so it should be positioned as a promising privacy-first keyboard rather than a mature Grammarly-style writing assistant.

Pricing: Free and open source.

Best for: Simple open-source Android keyboard.

Fossify Keyboard is an open-source Android keyboard from the Fossify project, which continues the privacy-focused Simple Mobile Tools style. It is better suited to users who want simple, transparent typing than to users who need AI rewriting, grammar coaching, or advanced cloud suggestions.

Pricing: Free and open source.
