Frequently asked questions

Does it add hashtags?
Yes, captions include a small set of relevant hashtags. You can edit or remove them before posting.
Is this Instagram Caption Generator really free?
Yes. You get free generations every day without creating an account. With a free Postsor trial you can generate for all 34+ channels at once and schedule posts directly.
How is this different from ChatGPT?
Every platform has its own length limits, tone and format. This generator applies platform-specific rules, so the output is ready to publish — not a generic draft you still have to rework.
Can I schedule the generated content?
Yes. Create a Postsor account, connect your channels, and schedule generated posts to publish automatically — or let weekly Autopilot plan your content for you.
