Content Drifter combines all these tools with AI-assisted content generation, scheduling, and multi-platform publishing. Create a week of content in minutes.
Start for $0Which of these are deterministic
20 of the 46 tools here put a model between what you type and what you get back. The other 26 are deterministic: the previews, the formatter, the size guides, the counters and the calculators return the same answer for the same input every time, which is what makes them worth checking a real post against. We say which is which because nobody else in this category does, and because a generative tool cannot honestly promise the second thing. We count that split from the grid above as this page renders rather than typing it, so it cannot drift from what is actually listed.
Comparing scheduling tools, not just using one?
These tools are free and need no account. If you are further along and actually choosing what to run your social media on, we keep honest side-by-side breakdowns, including what Content Drifter does not do. Start with Buffer, Hootsuite, Later or SocialBee. If you are weighing software against a person, the AI vs hiring a social media manager breakdown is the one to read, and Tribescaler users need a new home since it shut down.
Frequently asked questions
Are the Content Drifter tools really free?
Yes, and most need no account at all. They run in your browser and are deliberately built to be useful on their own rather than as a teaser, which is why things like the post previews and the size guide are complete rather than limited.
Which free tool should I start with?
If you write for LinkedIn, the post preview and the text formatter save the most time, because LinkedIn truncation and the lack of native bold are the two things people get wrong most. If you design carousels, start with the carousel size guide.
Do I need to sign up to use them?
Not for the tools themselves. Signup only matters when you want the workspace: AI-assisted drafting in your brand voice, scheduling, approval and publishing to 9 platforms. That has a free forever plan too.
