Got a question? Slide into our DMs
Tap a question and we'll answer it in the chat. You can also type your own.
Are the tools really free?
Yes. Every tool is free with no limit on uses. The site is supported by ads, so there's no paid plan for the basics.
Do I need an account?
No. Open any tool and start typing. There's no sign-up, email or trial.
Which platforms do you cover?
Instagram, YouTube, TikTok, LinkedIn and Facebook. Vote for the next one if yours is missing.
Do I need to connect my Instagram or TikTok?
No. You type in your own text or numbers. We never ask for a login and can't see private analytics.
Do you save what I type?
No. Calculators and generators run in your browser and nothing you type is sent to us.
Will the hashtags make my posts go viral?
No tool can promise that. Relevant tags help your post show up in search and topic feeds. Reach still depends on the content, timing and your audience.
How accurate are the money calculators?
They give a range based on the rate you choose. Real earnings depend on audience country, topic and the monetization program, so treat every result as an estimate.
How often do you update image sizes?
We check them every month and when a platform announces a change. Each size shows the date we last reviewed it.
