AI ad studio and Facebook group poster

AI writes the ads.
It posts them like a person.

Describe your business once. It finds who to reach, writes the Facebook ad copy, renders the ad creative, works out which groups those people are in, and posts to every one of them with different wording, a different photo and a different rhythm. So your posts keep getting shown.

Bulk posting is free, 500 posts a month, no card. The AI ad studio starts at $19 a month, and every account gets 20 AI ad creatives to try.

The AI marketer

One sentence about your business. A finished campaign out the other end.

Every other AI marketing tool hands you a paragraph and stops. The paragraph was never the slow part. Finding the audience, making the images, writing forty different versions and getting them published without being throttled is the slow part, and that is what this does. The full loop, week by week.

  1. 1Business

    You describe it once

    Real facts, prices, service area, proof, and any brand images. Stored once, read by every generation afterwards.

  2. 2Audiences

    It works out who buys

    Named segments with pain points, desires, objections and the words those people use themselves, researched against live web results.

  3. 3Ad creatives

    It writes and renders the ads

    Per audience: a hook, a body with spintax, a first comment, and an image rendered with the exact words the copy asked for.

  4. 4Groups

    It finds where they are

    The finder turns an audience into candidate Facebook groups. You cut the list, and it saves as a set you reuse every week.

  5. 5Posting

    It posts like a person

    Different wording, a different photo and a different gap for every group, inside your hours, stopping the moment anything looks wrong.

    How the poster works
AI ad creatives

It writes the words first, then renders the picture around them

Most image generators are asked to imagine an advert, and they produce a handsome scene with melted lettering across it. Here the copy model decides the angle, writes the hook and the body, and then writes the exact words that go on the image and where each one sits. Only then does the image model run, and it is placing known words rather than inventing them.

What comes back is a finished ad: a creative, the post it belongs to, the first comment carrying the link, and spintax already woven through the text. How the ad creative generator works.

  • On-image text written verbatim, in reading order
  • Your brand imagery and product shots feed the render
  • A batch of creatives per campaign, so no group sees the same image twice
  • Every one editable, replaceable or deletable before anything posts
AI audience research

A demographic is not an audience

Women 30 to 45, suburban, values convenience. It feels like research and you cannot write one sentence from it. A usable segment is a situation: the moment a person is in, what is going wrong for them right now, and the words they would use complaining about it to a friend.

That is what the targeting stage returns, grounded on live web results about your actual market rather than the average of every marketing article ever written. Each segment also carries the phrases those people would search Facebook by, which is what the group finder runs on. What a segment contains, field by field.

Why this matters

Facebook rarely deletes bulk posts. It stops showing them.

Meta describes its own approach as remove, reduce, inform. Content that breaks a rule gets removed. Everything that merely looks like spam gets reduced: the post stays on your profile, it stays in the group, it looks completely normal to you, and it is shown to a fraction of the people it would otherwise reach. Nothing tells you it happened, which is why people call it a shadowban.

That is the whole problem with bulk posting, and it is the reason an AI ad generator on its own is worth very little. Twenty perfect ads are worthless if they land as twenty identical-looking posts inside four minutes. Every setting in Serious Poster exists to keep you out of that bucket, and the full guide to Facebook shadowbans covers how to tell whether you are already in it.

Same post, same group, one difference
Link in the post bodydistribution reduced
Link in the first commentshown normally

The same text in every group

Near-identical copy across many groups is the cheapest possible thing to detect, and the most common reason a campaign quietly stops being shown.

Spintax plus a pool of separate posts, so no two groups get the same wording.

Posting faster than a person could

Twelve groups in four minutes is not a rhythm a human hand produces. A fixed interval between posts is even easier to spot than a fast one.

Randomised gaps, bursts with long breaks, and posting hours you set.

An outbound link in the post body

Posts that send people off Facebook are consistently shown to fewer of a group than posts that keep them on it.

The post goes up clean and the link follows as the first comment.

The same photo attached every time

Images are fingerprinted. Forty posts carrying one identical file group themselves together whether or not the text varies.

Media sets and a batch of generated creatives, each post drawing its own.

Arriving and posting instantly

A real visit scrolls, pauses and produces keystrokes. A page that loads and submits a finished post in the same second did not have a person behind it.

Dwell time, feed scrolling, and text typed character by character.

Members hiding or reporting you

Negative feedback is weighted heavily, and hitting the same group over and over is the fastest way to earn it.

A per-group cooldown and daily caps, so you are never the person flooding a feed.

None of this is a guarantee, and anyone selling you one is lying. It is the removal of the specific things that are known to cost you reach.

One plate, every colour

Write a post once, or let the AI write it, and mark the parts that should vary. Every send picks its own combination, so no two groups get the same wording. How to write spintax that reads like a person, or have it written for you.

Hey everyone, just listed a clean 2 bed in Riverside. DM me if you want details.

Three steps, then it runs itself

  1. 1

    Install the extension

    It posts through the Facebook session you are already signed in to. No password, no API key, nothing to get approved.

  2. 2

    Generate or write a campaign

    Let the studio produce the ads, or write your own. Either way you end up with a template: texts, first comments, media, groups and pacing.

  3. 3

    Press start, walk away

    Close the popup. It keeps running in the background, survives a browser restart, and tells you when it is finished.

The full walkthrough of posting to multiple Facebook groups

The one that matters most

Your link goes in the first comment

A link in the body of a group post sends people off Facebook, and posts that do that are shown to fewer of the group. Serious Poster puts the post up clean, waits a randomised minute or two, then leaves the link as the first comment underneath. On its own this usually does more for you than every other setting combined, which is why the AI writes the first comment as its own piece of text rather than leaving you to paste one.

Lead Radar

The best lead in the group is the person already asking

Somebody posted three hours ago wanting exactly what you sell, got two useless answers, and will hire whoever replies well and replies first. While the extension works through your groups it reads those same feeds for your buyer-intent keywords and saves every match, with the author, the text, the group and a link straight to the post.

The AI drafts the reply. You edit it and send it yourself, on Facebook, by hand. It never messages anyone, never comments for you, and never collects a contact list. How to work group leads properly.

AI ad generator

Audiences, copy, hooks, first comments and a rendered creative per ad. Each finished ad lands as a template you can post immediately.

Write with AI, free

In the dashboard editor and in the extension popup. Describe a post or paste one you already like and get it back with spintax woven in. Not metered.

Lead Radar

While it posts, it reads the same feeds for buying intent and saves the matches. It drafts the reply. You send it yourself, by hand.

Group finder

Scan the groups you already belong to, or let an audience suggest the ones you are missing. Save either as a reusable list.

Media sets

Generated creatives and your own photos in one pool. Each post draws its own attachment, so a campaign never ships forty copies of one image.

Human pacing

Dwells on the page, scrolls the feed, types character by character, then waits a randomised few minutes. No fixed interval anywhere in the run.

Templates that stick

Everything saves together, including your timing settings. Load it next week and it is exactly how you left it.

It stops when told

The moment a block, checkpoint or rate warning appears, the run halts and says so. Pushing through a warning is how a one-day limit becomes permanent.

Pricing

Posting is free. The paid plans are the AI studio, metered by what it makes rather than by seats or campaigns. No contract, cancel in two clicks.

Straight answers

What does the AI actually do?

Four things. It researches your market and returns named audience segments. It writes the ads for each of them, with the hook, the body, the spintax and the first comment. It renders an image for every ad, with the on-image text it wrote. And it drafts replies to the leads that Lead Radar catches. Everything it produces is editable, and nothing gets posted until you press start.

Can AI write and post my Facebook group posts for me?

Yes, with you approving in the middle. The studio generates the posts and the images, you read them and fix anything wrong, and the extension publishes them across your groups on a randomised human schedule. There is no mode where it writes and posts unattended, which is deliberate rather than missing.

Do the AI images have readable text on them?

Usually, because the words are decided before the picture. The copy stage writes the exact on-image text and a full scene description, and the image stage is told to place those words rather than invent them. You see every creative before anything is posted.

Is the AI free?

The post writer and the spinner are free and unmetered on any signed-in account. The heavier studio, which does audience research and renders creatives, is what the paid plans meter, and a free account gets a one-off credit of 20 ad creatives and 3 audiences to run it properly once.

How much does it cost?

Posting is free: 500 posts a month on a free account, unlimited on a paid one, with every pacing control included either way. Starter is $19 a month for 40 AI ad creatives and 15 audiences. Pro is $69 for 150 creatives and 50 audiences. No contract, cancel in two clicks.

Will this get my Facebook account banned?

Nothing can promise that, and anyone who does is selling you something. What it does is remove the patterns that get reach reduced: identical text, fixed intervals, instant posting, links in the post body, one image everywhere, and running through the night. Start slow, use warmup on a new account, and leave the safety stop on.

Do you need my Facebook password?

No. It works inside the browser you are already signed in to. We never see your credentials and there is nothing to enter.

How would I know if my reach is already reduced?

Usually you cannot know directly, and that is rather the point of it. The tell is a post that looks completely normal on your own screen while getting a fraction of the views, reactions or replies that the same kind of post used to get in that group.

Does it find groups for me?

It suggests them. It can read the groups you already belong to and hand them back as a list, and it can turn an AI audience into candidate groups using the search terms that audience carries. You accept or drop each one, and it never joins a group on your behalf.

What is Lead Radar?

A feed scanner. While the extension works through your groups it reads those feeds for posts matching your buyer-intent keywords, then saves each match with the author, the text, the group and a link. The AI drafts a reply. You edit and send it yourself on Facebook, because automated outreach under your own name is how accounts get restricted.

What if Facebook changes their layout?

The extension carries fallback selectors and we ship updates through the Web Store. If posting does break, it stops and tells you rather than quietly doing nothing.

Can I run more than one Facebook account or several clients?

Yes. It follows whichever Facebook account that browser profile is signed in to, so use a separate Chrome profile per account. The studio holds each business separately too, with its own audiences, brand imagery and group lists, which is what Pro is really for.

How many Facebook groups can I post to at once?

As many as you belong to, though the useful answer is fewer than that. The tool paces a run across hours rather than minutes, holds a cooldown per group and respects a daily cap you set, because thirty groups at full reach beats sixty groups at a fifth of it.

Do I have to use the AI?

No. Write everything yourself and the poster works exactly the same. The two halves are joined at one seam, which is that a generated ad becomes an ordinary template, so you can use either half alone without noticing the other exists.

Generate a campaign. Post it properly.
