Everything RobinReach does
The free tools are the start. Here is the rest.
RobinReach plans, writes, publishes and measures your posts, and it publishes to 13 networks. Pick a chapter or let the reel play: each scene is a real feature, shown with example data.
A caption is typed, an image is attached, all 13 networks are selected and the post goes live on each of them.
Posts fill a month calendar, one is dragged to Thursday and a new post is added on Saturday.
A short brief becomes a caption for each network and a matching image.
A new Instagram Reel is picked up and posted again to TikTok, YouTube and other networks.
A reach chart, engagement totals, top posts and a best times grid.
Comments from several networks arrive in one list and one of them gets a reply.
A comment with the keyword MENU triggers a direct message with a link.
A link in bio page on a phone, with buttons and the latest posts.
A client opens an approval link, reviews a post and approves it.
A chat asks the assistant to plan and schedule the week. It checks the best times, schedules the posts, and the week fills up on the calendar.

Questions
AI post generator questions
How do I write a social media post with AI?
Type what the post is about, choose the network and a tone, and press Write my post. You get a finished caption you can copy straight away, with hashtags and a call to action where they fit.
Is the post generator free?
Yes. You can write 5 posts a day without an account and 15 a day with a free RobinReach account.
Which networks does it write for?
Instagram, Facebook, X, LinkedIn, TikTok, YouTube, Pinterest, Threads, Bluesky, Mastodon and Google Business Profile, plus a general option that isn't tied to one network.
Can I choose the tone?
Yes: professional, casual, friendly, humorous, inspirational, educational, conversational, authoritative or general. A topic area, such as Food and cooking or Marketing and growth, shapes the wording too.
Does it add hashtags?
It asks for three to five relevant hashtags, and adds emojis and a call to action where they fit. If hashtags are all you need, the free hashtag generator is built for that.
Does it stay within the character limit?
The tool asks the AI to stay within the limit of the network you pick (for example 280 characters for X) and shows the character count next to the result. AI can run over, so check the count before you post.
What happens to the topic I type?
It's sent to OpenAI to write your post, and we don't add it to any account or show it to anyone else. Avoid typing anything confidential.
Can I post it straight from here?
Not from this page: you copy the post and paste it where you publish. With a free RobinReach account you can schedule posts to 13 networks from one calendar.

A post generator that knows the network
Staring at an empty box is the slowest part of posting. This generator turns a topic into a finished caption for the network you pick, in the tone you ask for, so you start from something to edit instead of a blank page.
- Draft a caption for a launch, a sale or an announcement
- Get unstuck when you have a topic but no words
- Try the same idea in a different tone for each network
- Fill your content calendar faster
It's made by RobinReach, the social media scheduler. When the post is ready, RobinReach schedules it to every network you use from one calendar.
AI can get facts wrong. Read every post, check names, prices and dates, and make it sound like you before you publish. Generated posts are drafts.
