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
Prompt optimizer questions
How does the prompt optimizer work?
You write a prompt and choose a mode. An AI rewrites it following that mode's goal, for example adding a role, constraints and an output format, and lists the changes it made. You then copy the new prompt into ChatGPT, Claude or any other tool.
Is the AI prompt optimizer free?
Yes. You can optimize 5 prompts a day without an account and 15 a day with a free RobinReach account.
Does it work with ChatGPT, Claude and Gemini?
Yes. The result is plain text, so you can use it in ChatGPT, Claude, Gemini, Copilot, an image generator or any other AI tool. It isn't tuned to one model.
Which mode should I choose?
Beginner for a simple, clearer prompt. Advanced for the most structure and detail. Creative for images, stories and style. Technical for code and data. Marketing for copy that has an audience and a call to action.
How long can my prompt be?
Up to 500 characters, and at least 10. For a longer prompt, optimize the main instruction and add the rest by hand.
Will the optimized prompt always give a better answer?
Not always. It's a stronger starting point: clearer and more specific. Run it, read the answer and keep adjusting, because only you know exactly what you want.
Is my prompt kept private?
It's checked by OpenAI's moderation service and rewritten by OpenAI, and we don't add it to any account or show it to anyone else. Keep passwords, keys and confidential details out of prompts.
Is there a way to skip writing prompts?
Inside RobinReach, RobinGen writes social media posts from a short idea, so you don't have to write the prompt yourself. A free account includes it, with a monthly allowance.

Better prompts, better answers
An AI can only work with what you give it. A vague prompt gets a generic answer, while a prompt that says who it's for, what to include and how the answer should look gets something you can use. This optimizer does that rewriting for you, in the style that fits the job.
- Turn a vague request into clear instructions
- Add a role, a format and constraints
- Prepare a prompt for an image generator
- Write a prompt for code or data work
It's made by RobinReach, the social media scheduler that posts to every network from one calendar.
An optimized prompt is a stronger starting point, not a guarantee. Run it, read the answer and keep adjusting.
