Most scheduling tools take one post and put the same words on every network. PostSiete does the opposite: you write one idea, and it produces a native draft for each platform — a different length, a different opening, a different assumption about who is reading — previewed exactly as it will...

Questions & Answers

As answered by people managing PostAnything and PostSiete.

What makes your product unique?

PostAnything's answer

Most schedulers expect you to arrive with a finished post. PostAnything starts one step earlier: you can bring literally anything — a rough idea, a photo, a video, a product page URL, a YouTube video, a PDF, a voice memo, a trending topic, or a competitor's post to remix — and it turns that into platform-ready posts for Facebook, Instagram, LinkedIn, Pinterest, X, Threads, Bluesky, TikTok and YouTube. Each platform gets its own version with the right tone, format and character limits, media is automatically resized for each one, and everything is scheduled and published through the official APIs. It's the content creation and the publishing in one tool, instead of an AI writer plus a separate scheduler.

Why should a person choose your product over its competitors?

PostAnything's answer

Three reasons. First, it does more of the work: tools like Buffer and Hootsuite schedule what you've already written and resized, while PostAnything writes the posts, tailors them per platform and resizes your media too. Second, it's priced for small businesses and creators, starting at $15/month, with a free trial that includes every feature — no credit card and no time limit. Third, each post counts once no matter how many of the 9 platforms it goes to, so you're not paying per channel. If you're currently using ChatGPT to write captions and then copy-pasting them into each app, PostAnything replaces that whole routine.

How would you describe the primary audience of your product?

PostAnything's answer

Solo creators, small business owners and e-commerce sellers who know they should be posting consistently across platforms but don't have the time or a social media person to do it. We also serve freelancers and small agencies managing social media for several clients, with a multi-brand workspace so they can switch between clients in one click.

What's the story behind your product?

PostAnything's answer

I've been building social media automation software for around 20 years, including a line of posting tools for Pinterest, Instagram, TikTok and Threads. Over that time the same complaint kept coming up from customers: posting wasn't the hard part anymore — coming up with content for every platform, rewriting it for each one, and resizing images was. When AI got good enough to write content that doesn't sound robotic, I built PostAnything to solve the whole problem in one place: give it anything you've got, and it handles the rest, all the way to publishing.

Which are the primary technologies used for building your product?

PostAnything's answer

PHP, MySQL, ChatGPT, ffmpeg for video processing, and the official APIs of each social platform for publishing.
