Spreenity alternative: SyncBooster
SyncBooster is a Polish app where you write one sentence about a post to an AI assistant, and it writes the caption, picks hashtags, and publishes to Facebook, Instagram, LinkedIn and Google. Spreenity is also a Polish, cheaper content calendar, but its AI is limited to suggesting post topics - you write the rest of the content yourself. Below is an honest comparison: what each tool does better, and who it is for.
SyncBooster or Spreenity - how they differ
Honestly: where we win, and where Spreenity is better. As of September 2026.
| Feature |  SyncBooster |  Spreenity |
|---|---|---|
| Who writes the post content | AI does - one sentence of context gets you a ready caption, hashtags, and a version tailored to each platform. | Partly - AI only suggests topic ideas (a monthly limit depending on the plan), and you write the actual post content yourself. |
| How posts get created | Chat is the whole interface - you talk to the assistant like a colleague. | No - it is a calendar with a form for scheduling posts, with no AI chat interface. |
| Publishing straight from the conversation | Yes - from the chat to every connected profile. | No - you publish from the calendar after preparing the content manually. |
| A photo turned into a finished post | Yes - the AI reads your photo and writes a post around it for every platform. | No - no such feature is described; you add photos yourself to a post you schedule. |
| Where you publish | Partly - Facebook, Instagram, LinkedIn and Google Business Profile (no TikTok). | Partly - Facebook, Instagram, Google Business and TikTok (no LinkedIn). |
| A real free plan | Yes - no credit card, ongoing, with a limited monthly token allowance. | No - the cheapest plan is paid; the 14-day trial requires a credit card. |

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.

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.
