FlirtCopilot suggests ten replies at a time. When someone copies one, that is a vote: out of ten options, it is the one they were willing to send. We looked at more than 12,000 of those copied replies from the last 90 days. Four things stood out.
1. There is no killer line
We expected a leaderboard of killer openers. There is none. Across more than 12,000 copied replies, no single line was copied by five or more different people, and almost every copied line is unique. The replies that get copied are the ones that mention the other person's actual message, bio, photo or joke. The generic line loses to the specific one, which is the whole reason a reply written from the real conversation beats a list of pickup lines.
2. The reply people choose is one text bubble long
The median copied reply is 86 characters, roughly 15 to 17 words. Half of all copied replies fall between 70 and 106 characters. Only 10% are shorter than 58 characters, and only 10% run past 136. That is one bubble on a phone: long enough to say one specific thing and ask one thing back, short enough to read without scrolling.
| Copied reply length | Characters |
|---|---|
| Shortest 10% | under 58 |
| Lower quarter | 70 |
| Median | 86 |
| Upper quarter | 106 |
| Longest 10% | over 136 |
3. Half of them ask something
49.5% of copied replies contain a question. The pattern that shows up over and over is a specific callback followed by an easy question: notice one thing in their message or profile, react to it, then hand them the next move. Only about one in four copied replies contains an emoji, and about one in eight opens with the other person's name.
4. Sweet beats funny, by a lot
Every request carries the tone the person asked for. Lines written in a sweet tone were copied almost three times as often as funny ones, and funny was the least-copied tone of all. Two honest caveats: people choose the tone themselves, so part of this is who picks sweet versus who picks funny; and funny is the hardest thing to write for someone else, human or AI.
What to take from this if you write your own
- One bubble. Aim for 70 to 106 characters. If it needs scrolling, cut it.
- Specific beats clever. Mention the thing they actually said or showed. The generic line is the one nobody chose.
- End on an easy question. Half of the copied lines do. It hands them the next move.
- Warm over funny. Sweet lines were copied almost three times as often as funny ones. A joke is the hardest thing to land in one line.
- Use their name sparingly. About one in eight copied lines opens with it; more than that reads like a form letter.
- An emoji is optional. One in four copied lines has one; three in four do not.
How we counted
Window: 30 June to 28 September 2026: more than 12,000 replies that people copied from FlirtCopilot's suggestions. Test traffic, crawlers and our own team's usage are excluded. "Copied" means the person tapped copy on a suggested line; we cannot see whether it was sent.

In this data the median copied reply was 86 characters, about 15 to 17 words, and half fell between 70 and 106. One text bubble.
People clearly think so: 49.5% of the replies they copied contained a question. A question hands the other person an easy next move.
Sweet. Sweet lines were copied almost three times as often as funny ones, the least-copied tone. People choose the tone themselves, so part of this is who picks which tone, but the gap is large.
