Why we give these away

Most of what a social media team does every week is not creative work — it is checking. Checking whether a caption will fit. Checking which image size a platform wants. Checking whether an engagement rate is any good. Checking that a campaign link is tagged so the traffic can be traced back.

None of that needs a subscription, so none of it is behind one. These pages are the same reference data our own product runs on — the character limits, the pixel specs, the crop ratios — pulled out and made usable on their own.

ReachXpand is the paid part: it learns your brand from your website, writes and designs the posts, publishes them across every platform on a schedule, and answers customer enquiries in your own voice. See how it works when checking things by hand stops being enough.

Questions

Are these tools really free?
Yes. Every tool on this page runs entirely in your browser, needs no account, and has no usage limit. We do not see what you type into them — nothing is sent to our servers.
Do I need a ReachXpand account to use them?
No. There is no sign-up, no email wall and no trial to start. ReachXpand is a paid product, but these tools are not part of it.
Can I use them for client work?
Yes. Use them for your own brand, for clients, in a course or inside an agency deck. If they are useful, a link back to the tool page is appreciated but not required.
Is my data stored anywhere?
No. The calculations happen in JavaScript on your own device. Nothing you enter is transmitted, logged or stored.

Stop checking. Start publishing.

ReachXpand writes the caption, designs the image at the right size for every platform, schedules it, and replies to the comments it brings in.
