Postiz alternative: SyncBooster
SyncBooster is a Polish app where you create posts by chatting with an AI assistant and publish them from that same chat to Facebook, Instagram, LinkedIn and Google. Postiz also has an assistant you can talk to - that needs saying plainly. The difference is who each tool was built for: Postiz is an open-source product for developers, and the thing it advertises ("connect any AI agent") needs your own AI subscription, an API key and setup. It is English-only, bills in US dollars, and the invoice comes from a Hong Kong company. Below is an honest comparison: what each tool does better, and who it is for.
SyncBooster or Postiz - how they differ
Honestly: where we win, and where Postiz is better. As of July 2026.
| Feature |  SyncBooster |  Postiz |
|---|---|---|
| How posts get created | Chat is the whole interface - you create posts by talking to an assistant, like talking to a colleague. In Polish, from minute one. | Also a conversation - Postiz has a built-in assistant (Smart Agent) on every plan, in English. The full version of that promise, driving the tool from any AI agent, only unlocks after technical setup. |
| Publishing straight from the conversation | Yes - from the chat to every connected profile | Yes - you can ask the assistant in the conversation to schedule a post |
| Works without technical knowledge | Yes - create an account, connect your profiles and write to the assistant in Polish. Nothing to install, no second AI subscription needed. | Partly - the built-in assistant on a paid plan works right away, but what Postiz advertises ("connect any agent: Claude, ChatGPT, Cursor") needs your own AI subscription, an API key and wiring the two tools together. The free version means standing the app up on your own server. For a non-technical person that is usually a wall. |
| A photo turned into a finished post | Yes - the AI reads your photo and writes a post around it for every platform | No - Postiz generates AI images and video, but there is no "drop in your own photo and get a finished post" path |
| AI for content included in the plan | Yes - AI is the heart of the app and every plan has it; you only pay for what you actually generate | Partly - the assistant is on every plan, but AI images and video have a monthly cap that depends on the plan. If you drive Postiz with your own agent, you pay for that subscription separately. |
| Polish language and support | Yes - the app, the assistant and help are all in Polish | No - the site, the app and the documentation are English-only, and support runs through Discord |
| Where you publish | Partly - Facebook, Instagram, LinkedIn and Google Business Profile (4 networks) | Many more - 30 channels: alongside Facebook, Instagram, LinkedIn and Google also X, TikTok, YouTube, Pinterest, Reddit, Discord, Slack and developer communities |
| Open source and your own server | No - SyncBooster runs only as a cloud service | Yes - this is a real strength of Postiz: the code is open, so you can host it on your own server for free and change it however you like |
| Stats for published posts | Partly - basic data about your posts | Yes - reach, likes, comments, shares and engagement across every connected channel |
| VAT invoice from a Polish company | Yes - a Polish entity, prices in zloty with a VAT invoice | No - the contracting party and invoice issuer is Gitroom Limited of Hong Kong, billing is in US dollars, and any disputes go to the Hong Kong courts |

Both tools let you talk to an AI.
How SyncBooster works
Drop in a photo from a job, a dish, a product or an event and write one sentence about the post. SyncBooster turns it into ready-to-go versions with a preview for every platform - you just approve them.
That's all it takes to get a ready post for every platform.
The whole SyncBooster app is a chat with two assistants
No dozens of tabs and panels. One assistant teaches the app about your business, the other creates and publishes posts every day.
Onboarding Assistant
Teaches the app about your business
- Interviews you about the company and analyzes your website
- Sets your brand tone, target audience and post-writing rules
- Builds the knowledge base: offer, pricing, FAQ and certificates
- Goes online to get to know your business even better and see what your competitors are doing.
When to use it
Changing your pricing or adding a new service? Just tell it. The more detail you give about your business, the richer the posts the Social Media Assistant writes later.
Social Media Assistant
Creates and publishes posts
- Turns a short note and a photo into a ready post - one per platform
- You refine it in chat: make it shorter, fewer emoji, sound more confident
- Publishes and schedules on Facebook, Instagram, LinkedIn and Google
- Goes online to check current events or dig deeper into the topic it is writing about.
When to use it
Day to day. Drop in a photo or video and one sentence of context and you get a finished post for every platform. Over time it learns your edits, so it sounds more and more like you.
And on top of that, SyncBooster Studio: AI image generation and a publishing calendar.
Publish posts and reels on every platform
Publish instantly or schedule posts for when your audience is actively thinking about your offer.

SyncBooster is built for posting right here, right now
Drop a photo of your work, a dish, a product or an event into the chat, write one sentence about what the post should say, and get ready-to-publish drafts for every platform.

What our users think
See how SyncBooster helps businesses like yours.
We are really very satisfied with using this app. It is a huge help in running social media - definitely one of the best things we have implemented.
We have pages in both Polish and English, and the AI creates posts in both languages without any issue. One sentence or idea is enough for the AI to create a long, professional post or reel. The content is refined and ready to publish.
A big plus is the full publication automation - the app adds photos itself and publishes content across all social media, with the option to set a specific day and time. Our profiles are regularly updated and constantly active.
The app saves enormous amounts of time and truly elevates the level of marketing in our company.
Natalia NiedolistekMarketing & Social Media Specialist - Top Racing
My job is to keep the crews busy, not write Facebook or Instagram posts. It used to be a struggle - now it's my main tool for filling the calendar.
A client cancelled on Saturday, and thanks to this app I had a post with a graphic about the open slot in 2 minutes. The phone rang in the morning - the crew went to work as usual. Zero downtime, full calendar.
Michal KorwekFounder of Under Pressure - pressure washing
When I found this app, I immediately knew it was exactly what we needed. Everything works incredibly simply - almost like using Messenger. I upload photos of a sushi set, type “set 9,” approve the suggestion, and within moments I have ready-to-post content for all our social media channels. Brilliant in its simplicity.
Since we started using SyncBooster, we’ve noticed a clear increase in interest in our restaurant and more new guests coming through the door.
