Today: 14 posts for 6 clientsGenerate the whole day · 46 credits
Example screen with made-up agency clients.

15 clients. 15 voices.
300 posts a month.

Every client has their own brand book, language and colours. ChatGPT doesn't know any of it, and Canva doesn't write. So agencies still make every post by hand — and can't take on a new client without hiring.

01 · GENERIC

AI writes like AI, not like your client

The same exclamation marks, phrases and hashtags for a bakery and a law firm. You rewrite every caption.

02 · SAMEY

Every client looks the same

The same templates for every client. Mix the posts up and you can't tell whose is whose — and the client notices first.

03 · SLOW

Planning takes days

8–30 posts per client per month, Excel plans in ten different shapes, and topics that start repeating after three months.

WHO IT'S FOR

For everyone who has to post — not just agencies

One Postaja, three ways of working. Pick yours.

Businesses and individuals

Posting on your own? Postaja is your marketing department.

A hair salon, a restaurant, a farm, a coach or your personal profile. No agency needed and no hunting for ideas every day: upload what you have about yourself and Postaja writes posts in your voice.

Solo · €39 / monthTry it for 7 days
Freelancers

Running a few clients on your own.

Every client keeps their own voice and look, and you use one tool instead of six. More clients without more hours.

Agencies

5–30 brands, one team.

A month of posts for every client in one afternoon, ads in every size and an AI persona for video.

HOW IT WORKS

Four stops from brand book to post

Set up your first brand in 20 minutes. Have your first week of posts the same day.

  1. 1

    Upload what you already have

    Brand book in Word or PDF, price list in Excel, decks, logo, past posts. Postaja reads them verbatim and builds the brand's knowledge base.

  2. 2

    Import a plan or ask for ideas

    Any Excel, CSV, Word or PDF plan — it recognises the columns itself and keeps your copy verbatim. For empty days it suggests ideas you haven't used yet.

  3. 3

    Generate the whole day in one click

    Captions, images, carousels, animations and ads for every brand at once. The credit cost is on the button before you click.

  4. 4

    Review, download, publish

    Platform-style previews, a ZIP with a folder per post and the caption in caption.txt. Publish by hand and mark it done — the dashboard shows what's still open today.

QUALITY

Writes like your client, not like ChatGPT

Same task, same client. The difference is what Postaja knows about the brand: voice, rules, facts from the knowledge base and past posts.

WHAT YOU GET

An answer to every agency objection

Postaja is built for many brands at once. Every client is separate: their own brand book, rules, look and memory.

Brand DNA

Brand book, rules, examples and a knowledge base from PDF, Word, Excel and PowerPoint files. Every post records which brand-book version it used.

Team and roles

Owners and editors, each sees only their own organization. Invite teammates; an extra member is €9 a month.

Each client's own look

No shared templates. Postaja derives the visual identity from the client's logo and past posts and keeps it consistent.

Import any plan

Keep the client's plan as it is. AI recognises the columns, code reads the values — dates and copy stay exact.

180-day memory

Every idea is checked against the brand's last 180 days. Similar topics get a warning, repeats are never suggested.

Ad sets in every size

One ad, every placement. A ZIP with a folder per size and copy.csv with copy variants for your ads manager.

Animations and AI persona

Bring any image to life for Reels. An AI influencer with the same face every time — images and 5 or 10-second videos.

No cost surprises

Credit cost on the button before you run, a monthly spend cap and cost per brand on the dashboard.

Works with Claude

Postaja is an MCP server: send brand books, price lists and logos from a Claude chat straight into the right brand.

Every size the network asks for — pixel-exact

Postaja checks sizes, safe zones, caption length and hashtag counts before a post is marked ready.

PROOF · 4 BRANDS, 1 PERSON

Postaja posts for its maker's own brands every day

Four brands, four voices, three networks. Content for LinkedIn, Instagram and X is made in Postaja and published by one person — no team.

AGENCY PILOT

30 days of posts for 3 clients. €99.

The Studio plan for three of your clients. We import their brand books, plans and past posts together — you test on real work, not demo data. Switch to yearly and the €99 is deducted.

Founding customers

The first 20 customers get free onboarding of every brand (€149 per brand), a direct line to the founder and a say in the roadmap. We never cut the base price.

The 8-out-of-10 guarantee

Upload the brand book, at least 3 past posts and a plan for one client. If in the first 30 days fewer than 8 out of 10 posts go out without a manual copy edit, we refund your subscription and set up your brands for free.

The risk is ours. All you put in is one hour for the import.

FAQ

What agencies ask on the first call

Does Postaja publish directly to the networks?

Not yet. You download a ZIP with every file and caption, publish, and mark the post as published in Postaja. Direct publishing and scheduling are coming as an add-on.

I'm not an agency. Is Postaja for me?

Yes. The Solo plan is for businesses and individuals who post on their own — a salon, a restaurant, a coach or a personal profile. Upload what you have (website, price list, a few past posts) and Postaja writes in your voice. You can try it for 7 days.

What is a credit, and what if I run out?

A credit is a unit of AI usage: a caption costs 1, an image 2, a persona video 25 or 40. You get a warning at 80 % and can buy 500 credits for €25 or 2,000 for €80. Nothing is charged without your OK.

My client has no brand book. Now what?

Upload what you have: website, price list, logo, past posts. If you like, we set the brand up for you in 48 hours (€149 one-off, free for founding customers).

Can anyone else see my clients' data?

No. Every organization is isolated, and automated tests check this on every change. Files are kept in private storage in the EU with time-limited access.

Which languages does it write in?

The language you set for the brand and channel — Slovenian, Croatian, English and others. The app itself is in Slovenian and English.

Is there a lock-in?

Cancel the monthly plan any time; it runs to the end of the period. The yearly plan costs 10 months and includes free onboarding of every brand.
