Frequently asked questions

What's the main difference between KOPY and Grammarly?

KOPY is an iPhone keyboard built specifically for fast message replies in apps like Tinder, WhatsApp, Slack, and LinkedIn. Grammarly is a broader AI assistant. KOPY optimizes speed and in-app flow, while Grammarly is better for wider standalone AI tasks.

Can't I just use Grammarly for message replies?

You can, but it usually requires app switching, prompt writing, and copy-pasting the result back into your chat. KOPY removes those steps by generating replies directly where you type, often in under 2 seconds, with mode and tone presets already tuned for messaging.

Is KOPY powered by Grammarly?

KOPY is an independent AI reply product and can use multiple model providers behind the scenes. The key point is workflow: KOPY is designed around keyboard-native replies and context modes, not around a standalone assistant interface that needs manual prompting for every message.

Which is better for writing cleaner replies quickly?

For writing cleaner replies quickly, KOPY is usually faster because it stays inside your iPhone keyboard and gives one-tap tone control. If you need long-form writing, deep analysis, or complex multi-step reasoning in a dedicated assistant interface, Grammarly can be a better fit.

Which is cheaper?

KOPY Pro starts at $12.99 per month with a free-to-start option. Competing assistants often have higher premium tiers around $20 per month depending on provider and plan. The best value depends on whether your main job is mobile replies or broader assistant workflows.

Can I use both?

Yes. Many users keep a general-purpose assistant for research and long writing, then use KOPY for high-frequency mobile replies across messaging and work apps. The workflows complement each other: one for depth, one for speed inside your iPhone keyboard workflow.
