Social posting automated to look human
A scheduler that queues captioned images to Instagram, LinkedIn and Facebook twice a day at randomised times, so a feed never looks machine-run.

An automation that takes captioned images and schedules them to Buffer channels for Instagram, LinkedIn and Facebook, two posts a day, at a randomised time inside a morning and an evening band rather than the same minute each day. It removes a recurring manual task without producing the metronomic posting pattern that makes an account look automated.
The problem
Posting twice a day by hand is a small task that never finishes, and it gets skipped on the days it matters. The obvious fix, a fixed-time cron job, is visibly robotic: a feed posting at 09:00:00 every single morning reads as a machine, which is the opposite of the intent.
What we built
- 01
Pick a random time inside a morning band and an evening band for each day, so the cadence is regular but the timestamps are not identical.
- 02
Hand off to Buffer rather than to each platform's own API, so one integration covers Instagram, LinkedIn and Facebook.
- 03
Keep captions with their images as the input, so the content decision stays human and only the scheduling is automated.
- 04
Run unattended, because an automation that needs a daily check has not removed the task.
What it does now
- Two posts a day go out without anyone remembering to send them.
- Timestamps vary, so the account does not read as machine-run.
- One integration serves three platforms.
What people ask about this work.
Why randomise the time an automated social post goes out?
Because an identical timestamp every day is the clearest signal that an account is automated. Randomising inside a band keeps the cadence you want while removing the pattern, and it costs nothing to implement.
Is it better to automate through a scheduler like Buffer or each platform's API?
A scheduler, usually, when you post the same material to several places. One integration covers Instagram, LinkedIn and Facebook, and you inherit its handling of each platform's quirks and policy changes. Direct platform APIs are worth it when you need something the scheduler does not expose.
