Frequently asked questions

How does KOPY work with Twitter/X?

KOPY runs as an iPhone keyboard inside Twitter/X. Copy the incoming message, switch to KOPY, choose mode and tone, then generate. In under 2 seconds you get a draft tailored to timely public-thread engagement, and you can edit every line before sending.

Will Twitter/X or the other person know I used AI?

No. Twitter/X does not add an AI badge to text generated through KOPY. The reply is inserted as normal keyboard input. KOPY provides draft assistance only, and you keep full control over edits, timing, and the exact final message you send.

What's the best tone to use in Twitter/X?

Start with Insight for a reliable baseline, then adjust by context. If the thread is tense, pick Neutral or Disagree. If momentum is low, use Continue or Question. KOPY's 40 style combinations let you shift voice quickly without retyping from scratch.

Does KOPY work in Tweet replies and thread conversations?

Yes. If Tweet replies and thread conversations uses the iOS keyboard input field, KOPY works there too. That includes regular chats and most threaded inputs. You keep one consistent flow across apps instead of context-switching to a separate assistant and manually prompt-writing each reply.

Is my conversation data private?

KOPY is designed for minimal retention. Message text is processed only to generate a reply and is not stored as a permanent conversation log by KOPY. You review and edit everything before sending, which keeps sensitive communication in your control.

Is KOPY free for Twitter/X?

Yes, KOPY is free to start on Twitter/X. You can test the keyboard workflow immediately before upgrading. Paid plans increase usage and flexibility, but the core benefit is available right away: faster replies, lower friction, and less overthinking on iPhone.

Why is KOPY better than manual typing for Twitter/X?

Manual typing often breaks down when tone mistakes in visible conversations is the bottleneck. KOPY reduces that friction by turning thread stance, audience sensitivity, and reply precision into a usable draft in seconds. You spend less effort on phrasing and more effort on intent, timing, and relationship quality.
