Frequently asked questions
Do these generators use AI?
They use template-based generation, not large language models. That means results are instant, free, and offline, but you may want to personalise the output before posting.
Are the hashtags up to date?
The hashtag generator returns evergreen, niche-specific hashtags rather than trending tags. For trend-chasing, supplement these with what you see in the platform's trending tab.
Will Instagram or Twitter flag these captions as spam?
No. They're generic captions you can personalise. Posting copy-paste content across many accounts is what triggers spam filters. The captions themselves are fine.
