How to use AI for post descriptions and hashtags

AI works best when you don't treat it like a magic button, but like a quick sketchpad. Give it a good photo, an OLX ad or a saved public link, a clear goal and a few specifics, and it will be much easier to get the main description and versions tailored to Facebook, Instagram and Google. With TikTok, treat the result as common content to be checked along with the material and required settings before publishing.

Start with one goal for your post

AI for descriptions and hashtags is available on all Spreenity plans: Starter, Growth, Pro and Premium. Monthly limits are 5, 35, 150 and 350 proposals, respectively, and credits renew with a new billing period.

Before you start generating, answer a simple question: what is this post supposed to do? A post that is supposed to sell a service is written differently, a post that is supposed to remind you about a free date, and a post promoting a specific advertisement is written differently.

  • I want to show a product or service.
  • I want to attract messages or calls.
  • I would like to remind you about a seasonal offer or promotion.
  • I want to promote a specific ad or offer.

Choose the best starting point

You can start with a photo, your own OLX ad or a saved link. If you are adding several photos, choose the one that best explains the post without additional explanations. It is usually a photo of the product, the effect of the service or the most readable frame from the offer.

The rule of thumb is simple: if you have several photos, set position #1 to the one that best shows the topic of the post. If you start with a link, write down only the public http/https address and add a short intention, e.g. "show weekend promotion" or "encourage people to book". Only then generate content.

Give the AI ​​some specifics, not just a topic

The weakest results usually come from a very general entry such as "write a description of a beauty salon". A short set of specifics works much better: who the offer is for, what makes the service stand out, what the tone should be and what the recipient should do after reading the post.

  • Who is this post for: new customers, regular customers, people from the area, companies.
  • What is worth emphasizing: price, date, effect, convenience, location or limited availability.
  • What should the tone be: more specific, light, expert or sales-oriented?
  • What action do you want to trigger: message, call, click or save.

A ready-made example of entering AI

Instead of just writing "make a post about coffee", give the AI ​​a small brief. It can be short, but it should include the recipient, offer, tone, channels and an element that cannot be omitted.

  • Write a short description for a small cafe in Poznań. Topic: weekend set of coffee and cake to go.
  • Recipients: people from the neighborhood who drop by after work or while walking.
  • Tone: warm, specific, without excessive promises.
  • Prepare the main version, a shorter version for Instagram and 5-7 local or thematic hashtags.

Such an example does not have to describe a real company. It just needs to clearly show the context. AI prepares an editable draft, and the decision to publish or schedule it is yours.

Generate from a saved link when the link is the base of a post

If the starting point is an offer, blog entry, product card or announcement, save the public link from the dashboard using the "Save link" action. Spreenity checks that the address is a safe public http/https link and then stores it as material for a later draft.

  1. Save the link and add a short post intent if you want to direct the result.
  2. In composer, select the saved link from the saved links panel.
  3. Click generate to get an editable sketch for selected channels.
  4. Correct the text manually, check the links and only then publish or schedule a post.

In the wizard, you can select a saved link, add material and prepare a description for publication.

Generating from a saved link does not automatically publish the post, does not reserve a publication limit and does not add external photos. The AI ​​credit goes off only after the proposal has been generated correctly and technically accepted, and the result still goes to the regular editable fields of the post.

Treat the result like a good first draft

The best posts usually don't happen with just one click. AI is supposed to save you time at the start, but it's still worth doing the finishing touches your own way. Shorten too long sentences, remove generalities and add 1-2 details that sound like your business, not like a universal advertisement.

  • Leave only one main message.
  • Add specific details: district, date, type of service, offer variant.
  • Remove sentences that you wouldn't normally write yourself.
  • Match the tip to the channel: on Facebook you can leave a link in the description, on Instagram a "link in the profile" works better, on Google a specific button or a short local prompt, and on TikTok check the common description, material and required settings.

Checklist before publishing an AI draft

Before publishing, read the proposal as if it were written by a new person in the company. It is intended to speed up the work, but it still requires your assessment, especially when it concerns price, deadline, availability or terms of the offer.

  • make sure your sketch doesn't promise results you can't deliver
  • remove generalities and add one detail known only from your offer
  • compare price, date, hours and service name with current information
  • make sure the link is public, starts with http or https and matches the post content
  • match the tip to the feed before clicking publish or scheduling

Match the version to the place of publication

The same topic does not have to sound identical everywhere. Facebook may get a slightly more complete description with a link, Instagram a shorter description with hashtags, and Google Business Profile a local message with a clear step: reservation, purchase, contact or check details. TikTok may use shared content, so make sure your description matches your content and required channel settings before posting.

  • On Facebook, leave more context if it helps you understand the offer.
  • On Instagram, watch your first sentence, photo and hashtags.
  • In Google, write locally: what, where, when and what the customer should do next.
  • With TikTok, check the common description, video material, and required selections before publishing.
  • If you add a link, use a site that is public and relevant to the content of the post.

Choose hashtags based on the topic, not wholesale

When it comes to hashtags, more doesn't mean better. It's better to choose a few relevant ones than to post a long wall of random tags. Good hashtags help organize the topic of the post and suggest what the offer is about.

  • Combine 2-3 industry hashtags with 2-3 more specific ones related to the offer.
  • If you operate locally, also add hashtags related to the city or district.
  • Remove too general hashtags if they don't say anything about your post.
  • If you also post on Instagram, stick to the 30 hashtag limit.

A simple diagram that saves time

  1. Select a photo, OLX ad or saved link that best shows the offer.
  2. Set one goal for the post and briefly name your audience.
  3. Generate a proposed main description and version for selected channels.
  4. Improve your texts so that they sound like your brand and match your specific offer.
  5. Publish right away or schedule a post for a convenient time.

If you want to do it faster, in Spreenity you can combine your photo, main description, feed versions and hashtags in one place, then publish your post immediately or set it to be published later.
