Common questions
- Are these X tools really free?
- Yes. Every tool on this page is free to use with no login and no signup. Most of them run in your browser and do not upload what you type. Tools that need a server, like the AI tweet generator, say so on their own page.
- Do I need to connect my X account?
- No. None of these tools ask for your X login. You paste a post or a link, or type in your own numbers, and the tool works from that.
- Do these tools work for Twitter?
- Yes. Twitter became X in 2023, and these tools follow the current X rules: character counts, the 1500 x 500 header size and the creator payout requirements.
- Which tool should I start with?
- If you want to earn from X, start with the X payout calculator and the monetization requirements checker. If you want better posts, run your draft through the AI detector and the cutoff preview before you publish.
