Postsy alternative: SyncBooster
SyncBooster is a Polish app where you write one sentence to an AI assistant and get a ready post for Facebook, Instagram, LinkedIn and your Google Business Profile in about 30 seconds - any time you want. Postsy is also a Polish product with AI, but it works differently: the system generates a fixed number of posts per week according to your plan, and you approve the ready drafts in a panel instead of writing to AI whenever you actually need something. Below is an honest comparison: what each tool does better, and who it is for.
SyncBooster or Postsy - how they differ
Honestly: where we win, and where Postsy is better. As of September 2026.
| Feature |  SyncBooster |  Postsy |
|---|---|---|
| How posts get created | Chat is the whole interface - write one sentence to the assistant any time and get a ready post immediately. | Partly - the system generates posts automatically on a schedule from your plan, and you approve them in a panel or tweak them with one command to the AI Assistant. |
| Post quota | No fixed cap - generate new posts whenever you want, within your monthly token budget. | Partly - every plan has a fixed number of posts per week; more posts means a higher-tier plan. |
| Publishing straight from the conversation | Yes - write "publish" in the chat and the post goes out to every connected profile. | No - posts wait in a panel and go out at a set time only after you approve them. |
| Short AI-generated videos | No - AI video generation is in development. | Yes - on the Firma and Studio plans, AI creates short, few-second videos for your posts. |
| Where you publish | Facebook, Instagram, LinkedIn and Google Business Profile - all already active. | Partly - Facebook, Instagram and LinkedIn are active; TikTok and Google Business Profile are announced as "coming soon". |
| Multiple brands on one account | Yes - multi-brand support starts as early as the Biznes plan, and higher plans scale further. | Partly - managing several businesses on one account is only available on the top Studio plan. |

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. Once you approve them, they go out to all your connected profiles. On top of that: topic and competitor research, plus managing several businesses from one panel. It works best when you want to show a product or a finished job fast, or announce a free slot.
Who Postsy is for, and who SyncBooster is for
Choose Postsy if
- you want a fixed, predictable number of posts every week and just want to approve them
- you care about short AI-generated videos already on the lower-tier plans
- Facebook, Instagram and LinkedIn are enough, and TikTok and Google Business can wait
- you run a handful of businesses that fit into Postsy's top plan
Choose SyncBooster if
- you want to write to the AI assistant whenever you actually have time, without waiting for a schedule
- you need Google Business Profile today, not "coming soon"
- you run several brands and want room to grow without switching tools
- you do not need AI video generation yet, and photo-to-post is enough
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.
