One turns a written line into an image, at no cost, and Microsoft itself says it is licensed for personal, non-commercial use. The other writes the carousel, the Reels script and the caption with a CTA that do not exist yet. What each one solves, where each one stops and what the licence changes when the account belongs to your business, with the official pages read on 5 October 2026.
Both show up in searches from people who want to post more on Instagram, and they cover different halves of the same post: Designer handles the image, ZapPost handles what is written on it.

The rows are split between what only one of them does and what both deliver, each in its own way.
Designer's five rows are image work, and it does that work without charging. All of them start after you have decided what the post will say.

|---|---|---|
| Only ZapPost does | ||
| Builds the carousel screen by screen, with the text already split | ||
| Writes the Reels script and the caption with a CTA from the subject you pick | ||
| Matches your niche's voice, without you explaining the business on every post | ||
| Is sold to people posting on their own business account | ||
| Only Microsoft Designer does | ||
| Turns a written line into an image, with the free Microsoft account | ||
| Erases objects by brush or auto select, removes the background and upscales to 4K | ||
| Builds cards, invitations, collages, frames and banners in the same place | ||
| Creates a brand kit with logo, colour palette, font and brand voice, one saved at a time | ||
| Works inside Word and PowerPoint through the Copilot icon | ||

The licence row carries the most weight here, and it is not buried in fine print. The sentence "Designer is licensed for personal, non-commercial use with your Microsoft account." appears twice in the body of the official FAQ page, in the same tone as every other answer. One of them sits in the brand kit section, which talks about a personal brand for a book club, a family reunion and a recreational sports club. If the Instagram account you feed sells a service, that is the first thing to settle.
Microsoft Designer has no pricing table of its own. The official page answers the question in one line, "Yes, Designer is free to use. A subscription may be required for those who want to create more frequently.", and heavy use lands on a Microsoft 365 subscription. ZapPost charges one amount.
What exists is a 7-day guarantee. The card goes in right at the start.
The post ready on the spot, in your niche's tone, no commitment. Billed monthly; cancel anytime.
The same Studio, with premium personalization and priority support. You pay the 6 months at once.
Signing in with a Microsoft account is enough, and the page itself says those accounts are free and take a few minutes to set up. Projects are saved to the cloud and count towards the same storage quota as the rest of your account: the page warns that going over it may stop you saving new files and even sending and receiving email.
In the official AI credits and limits table, last updated in September 2026, image gen shows up as standard usage on those two plans. AI credits are deducted as you use AI across several apps, Designer alongside Word, Excel, Paint, Photos and Notepad, so the balance is not reserved for Designer alone.
These are the two upper steps of the same table, and there image gen becomes extensive use. The page warns twice, in a highlighted note, that "AI benefits are only available to the subscription owner and cannot be shared with others", and says limits vary by feature, entry point and system conditions, and may change over time.
Microsoft Designer's price shows up on our card as pricing on request, because Microsoft publishes no figure for it, and ZapPost costs US$19.00 a month on the single plan, or US$11.50/mo, billed every 6 months on the six-month one. Comparing the two by the number leads to the wrong conclusion, because what limits Designer does not show up in money. It shows up in the licence Microsoft spells out on the official page, and in the AI credits you share with the other Microsoft apps if you ever subscribe to 365.
Two things worth checking before you hand your posting routine to either one. Designer has no project recycle bin: the official page says that once a project file is deleted it cannot be recovered, and the images you upload go to your OneDrive. And the Microsoft 365 AI benefit stays with the subscription owner, according to the same page, so counting on a plan shared at home does not cover you. On ZapPost the card goes in on day one, with a 7-day guarantee, and cancelling happens through Hotmart.
Microsoft Designer's side comes first on purpose, because a comparison that only praises its own side helps nobody decide.
Microsoft writes twice, on the same page, that Designer is licensed for personal, non-commercial use. We give no legal advice, and what we can point at is where to read: the terms of use for the web app and the mobile apps, which that page links. ZapPost is sold to people posting on their own business account.
The picture came out well and the caption is still empty. In Studio you pick the format, say what it is about, and get the text written on the spot. That is the step before any editor, and no image generator covers it.
It sits in a note on the official page: because of the underlying image creation technology, any text in the generated image may not be in the requested language or may have spelling errors. A carousel is made of sentences your client reads, screen by screen, and in ZapPost those sentences are written as text.
You do not explain what your business does on every post. That is what separates copy that would suit any company from copy that speaks to your client.
In Designer, creating more frequently runs through a Microsoft 365 subscription, and credits there are deducted as you use AI across several Microsoft apps. On ZapPost the plan is one amount a month, with no balance in the middle.
You describe the scene in words and get options to pick from. If what blocks your week is having no image at all to work with, Designer solves that and finished text does not.
A Microsoft account is enough, and those are free. The official page says in plain words that Designer is free to use. On ZapPost the card goes in on day one, with a 7-day guarantee, and there is no free tier.
Erasing an object with a brush or an auto selection, removing and blurring the background, adding a frame, upscaling to 4K. None of that exists in ZapPost, which never opens the image.
Birthday cards, party invitations, collages and banners come out of the same place. ZapPost's delivery is built for Instagram and does not cover those uses.
The official page says images created with Designer's editing features carry metadata in the C2PA standard, so people can tell AI was involved. That is the honest way to record it, and ZapPost delivers no image to mark.
ZapPost solves the part that usually blocks people first, and Microsoft Designer solves the part that comes next. One takes care of the text existing, written and split by screen; the other takes care of the image existing, within the use its licence allows. Someone who opens the app on Tuesday morning, looks at the good-looking image they generated yesterday and closes it without posting has the first kind of problem, and no image writes the first screen.
The difference between the two shows up in which part of Tuesday is still yours.
There is no blank canvas. In exchange, what arrives is text: to draw or retouch an image, you still need an image tool.
Before step 1 you decide what the post will say, and that step is not on the list. It is the one that makes plenty of people close the app.
You can use both. ZapPost writes the week's content and Designer comes in when the image is missing: the photo you never took, the background that has to go, the frame for the promotion invite. One covers the text, the other covers the image, each within the use that fits it.
No. ZapPost generates no images, opens no files for editing and has no layers. It generates the carousel, the Reels script and the caption with a CTA in Studio, in your niche's voice, the moment you ask. Anyone who needs an image still needs an image tool, and Designer does that without charging, within the personal use its licence describes.
The official FAQ page says, in two separate places, that Designer is licensed for personal, non-commercial use with your Microsoft account. The sentence reads "Designer is licensed for personal, non-commercial use with your Microsoft account." We give no legal advice, and what we can point at is where to look: that same page links the terms of use for the web app and for the mobile apps, which are the documents that decide your case. Worth settling before your posting routine depends on the tool.
Partly. On its canvas you can ask for text suggestions and have existing text rewritten, and the official page describes that feature. What comes out of it is a loose sentence inside the design. Deciding the subject of Tuesday's post, which angle of your service becomes a carousel and what each screen says is still yours. ZapPost delivers that part written and split, with the Reels script and the caption alongside.
It is, and the official page answers it like this: "Yes, Designer is free to use. A subscription may be required for those who want to create more frequently." Light use costs nothing, and creating frequently runs through a Microsoft 365 subscription. The official AI credits and limits page explains that credits are deducted as you use AI across several apps, Designer among them, and warns twice that AI benefits stay with the subscription owner and cannot be shared with others.
It does not come back. The official page warns that Designer has no recycle bin and that a deleted project file cannot be recovered. Projects are saved to the cloud and count towards the same Microsoft storage quota as the rest of your account, and the same page says going over that quota may stop you saving new files and even sending and receiving email. Images you upload to Designer live in your OneDrive.
No. It delivers the content finished and you download and post it with your own hands. Designer does not publish either: it hands you the image at the size you chose. Anyone who wants a post going out on its own at a set time needs a scheduling tool, and the comparisons hub has both kinds side by side.
From the official Designer FAQ page and the official AI credits and limits page, both opened on 5 October 2026, and from the ZapPost pricing page. Designer publishes no pricing table of its own, which is why our card shows its price on request: what exists is the free Microsoft account and the 365 subscription for people who create frequently.
The Microsoft Designer alternatives page lists four editors with the price and the limit of each one, and the differences show up fast there: VistaCreate declares a free plan in its official table, Pixlr delivers layers and masks inside the browser, and Canva and Adobe Express sell the largest template libraries of the four. And the comparisons hub puts ZapPost side by side with each of them.
By Pedro, ZapPost. The Microsoft Designer licence, features and limits were read on the official FAQ page and the official AI credits and limits page on 5 October 2026, and the ZapPost plan on the pricing page. Rules and prices change without notice: if the date above looks old, check the source before deciding.
Picking the tool is the easy part. The hard part is having content ready on Tuesday morning, when the day already started tight.
