Here is the whole thing in one sentence: the click interval is the gap of time between one automatic click and the next.
That's it. That is the concept. A one-second interval means a click every second. A thirty-second interval means a click every thirty seconds. If you can read a kitchen timer, you already understand click intervals, and you can probably stop reading here. But there is a bit more worth knowing if you want to set a sensible one rather than a silly one.
Seconds, or milliseconds?
Most auto clickers let you set the interval in seconds. Some also offer milliseconds, which is where people occasionally trip up. A millisecond is a thousandth of a second, so an interval of 100 milliseconds is ten clicks a second, which is a lot of clicks and usually not what a normal human wants.
If your clicker is firing like a tiny angry woodpecker, check whether you set 100 thinking it meant seconds when the box was actually reading milliseconds. Nine times out of ten, that's the culprit.
Fixed interval vs random interval
A fixed interval is exactly the same gap every time. Click, wait ten seconds, click, wait ten seconds, forever. Reliable, but robotic. It has the rhythm of a metronome, and nothing in real life clicks with the patience of a metronome.
A random interval varies the gap between a minimum and a maximum that you choose. You might say "somewhere between twenty and forty seconds", and the clicker picks a fresh, slightly different gap each time. It is a small thing, but it looks far more like a person idly clicking and far less like a machine keeping perfect time. There is a longer look at why that matters in what a random interval auto clicker is.
For most purposes, random is the nicer default. A metronome is great for practising the piano and not much else.
So what number should you actually pick?
This is the bit people really want, and the honest answer is that it depends entirely on why you're clicking.
If you just want to stay active
If the goal is keeping a computer awake or a chat status green, you do not need many clicks at all. You only need enough activity to land inside the app's idle window. Slack, for instance, gives you roughly ten minutes before it marks you away, so a click every thirty to sixty seconds is already wildly more often than you need. A generous, relaxed interval is the sensible choice here. There is no prize for clicking the most.
If you're doing a repetitive task
Some people use auto clickers for genuinely repetitive jobs, like advancing through a slideshow or a long list. There the interval matches the task: as fast or as slow as the work needs, which might be a click every few seconds. Set it to the pace you'd click at yourself if you had the patience.
Minimum and maximum, not one magic number
This is where a random interval gets practical. Rather than one figure, you set a floor and a ceiling: a minimum gap and a maximum gap. The clicker then wanders between them.
Set them close together, say 25 and 35 seconds, and you get a steady but non-identical rhythm. Set them wide apart, say 10 and 90 seconds, and it feels much more casual and unpredictable. Neither is wrong. It is a dial you turn to taste, and you'll land on your own preference within about a minute of playing with it.
What about "left click interval"?
Same idea, narrower label. The left click interval is just the time between one automatic left click and the next. Since the vast majority of people only ever need left clicks, the click interval and the left click interval usually end up being the exact same setting. Do not overthink it.
Where Green Dotter fits
Green Dotter keeps this deliberately simple. You set a minimum and maximum interval in seconds, and it clicks at a randomised gap somewhere in between, in a safe area you choose. No milliseconds to fat-finger, no metronome, and you start and stop it yourself.
It is free for Mac and Windows, runs locally, and does exactly one job well: controlled clicking on a natural schedule. If you're still deciding whether a clicker or a mouse mover suits you, mouse jiggler vs auto clicker lays out the difference.
FAQ
What does click interval mean?
The click interval is the gap of time between one automatic click and the next. A one-second interval means a click every second. A thirty-second interval means a click every thirty seconds. It is simply how often the clicking happens.
What is a good click interval?
It depends on the job. If you just want to keep a computer or a chat status active, a long interval is fine, for example a click every thirty to sixty seconds. For faster tasks people use much shorter intervals, but for presence there is no need to hammer the mouse.
What is a random click interval?
Instead of clicking on the exact same beat every time, a random interval varies the gap between a minimum and a maximum you set, for example somewhere between twenty and forty seconds. It looks more natural than a perfectly regular click and avoids a robotic, metronome-like rhythm.
What does left click interval mean?
It is the same idea, applied specifically to left clicks: the time between one automatic left click and the next. Most people only need left clicks, so in practice the click interval and the left click interval are the same setting.
A note on workplace policies: how you handle presence depends on your role, your tools, and your employer's policies. Before relying on any presence or automation tool, make sure you understand what is allowed on your work device.
