Gboard is a brilliant general-purpose keyboard — autocorrect, swipe typing, predictions, GIF search. But its AI features stop at suggestion bars. Revert is purpose-built around AI: it reads the whole conversation, rewrites your draft in any tone, translates in real time, and learns your personal writing style. Many people keep both — Gboard for plain typing, Revert when they need AI help.
Microsoft's SwiftKey added a Copilot button that opens a chat overlay. That's still app-switching with extra steps. Revert keeps you in the conversation: tap and your reply appears inline. SwiftKey is owned by Microsoft and routes through Copilot; Revert runs partly on-device and routes the rest through its own proxy, with no analytics SDKs.
Apple Writing Tools is great if you live inside Apple apps. The catch: many third-party messengers — WhatsApp, Slack, Telegram, dating apps — don't expose the Writing Tools menu, or expose only a stripped-down version. Revert is a keyboard, so it works the same in every app. It also adds tone rewrites, translation, AR lenses, and personalisation that Writing Tools doesn't offer.
Google Magic Compose is genuinely useful — but it only works inside Google Messages on Android. If most of your chat happens in WhatsApp, Instagram DMs, or Slack, Magic Compose can't help. Revert works everywhere a keyboard works.
Many people already use ChatGPT to draft replies — they just do it in a separate app. The workflow: copy the message, switch to ChatGPT, paste, wait, copy the reply, switch back, paste. Revert collapses that to one tap inside the keyboard. You stay in the conversation; the AI comes to you.
Siri, Google Assistant, and Bixby can dictate or send messages, but they don't help with tone, translation, or context-aware suggestions while you type. Revert handles all three — and works silently inside the keyboard for situations where speaking out loud isn't an option.
