Questions about these tools

Are DemandBird’s tools free?
Yes. Every tool on this page is free to use. Some let you save your results or get a weekly email by entering your address, but you do not need to pay or start a trial.
Do I need an account to use them?
No. The tools run in your browser. A few offer to save your work to a DemandBird account, but that is optional.
Which tool should I use?
It depends on the job. Use the cost calculators to compare Hootsuite or Buffer pricing, the engagement rate calculator to benchmark a post, the post grader and formatter to improve LinkedIn posts, and the repurposer to adapt one post for every platform.

Most cover the major networks: LinkedIn, X, Instagram, TikTok, Threads, and Bluesky. Each tool lists the platforms it supports on its card.
