Will the posts sound like me?

Yes. Viuz learns how you write from the posts on your profile and from the voice settings you give it. Every draft also lists the sources it used, and you can edit any line.

Do I need design skills?

No. Every post starts from a ready-made layout in your colors and fonts. Write one line or pick one of your ideas, and the slides come out designed. You can still change any text.

Does it work for my kind of business?

Yes. Viuz learns from the brand you connect, whether you are a coach, a restaurant, a shop or a software company. Colors and voice are set for each brand.

Does it work on my phone?

Yes. You can review, edit, approve and schedule posts from your phone's browser. There is no app to install.

Are there extra costs per image or per post?

No. Images, slide design and posting are included. Your plan comes with 50 AI-made posts a month.

Do I still control what goes out?

Yes. You can review and edit every post before it goes out, or send it to a teammate or client to approve. If you turn on autopilot, you choose whether it posts for you or asks you first.

Which networks does it post to?

Instagram, TikTok, Threads, X and LinkedIn. Viuz posts to each one for you. On LinkedIn it posts to your personal profile, not to a company page.

How do I know the facts in a post are right?

Each post lists the sources Viuz read and the facts it used, so you can check them. Later it also shows how the post did.

Will my posts look AI-made?

We work so they don't. Layouts are designed by people, colors and fonts come from your brand, and captions are cleaned of common AI habits, like em dashes.

Can I cancel anytime?

Yes. Cancel from your dashboard, no support ticket needed. Your plan stays active until the end of the period you paid for: the month on monthly billing, the year on yearly billing.

Can one subscription cover more than one brand?

Yes. One brand is included, with all its Instagram, TikTok, Threads, X and LinkedIn accounts. Add as many brands as you want for $7 a month each. Each one has its own colors, voice and topics.

How does pricing work?

You start with a 7-day trial. Your card goes on file, nothing is charged for 7 days, and you can make 10 posts to try it. Cancel before day 7 and you pay nothing. After that it is one plan, Studio: 50 AI-made posts a month and every feature, paid monthly or yearly at the price above. One brand is included; extra brands are $7 a month each on monthly billing.

Will this replace me?

No. Viuz makes the posts that are easy to repeat: carousels, captions and your posting calendar. It does not film you. For Reels, it writes the script and the shot list, and you record it.

Postgrain schedules Instagram. Viuz designs the post and posts it.

Postgrain is a scheduler for Instagram, with direct messages and Insights. Viuz makes the carousel in your brand from one line and publishes it to five networks.

The difference is the post itself

As of October 2026, Postgrain describes itself as a platform to manage Instagram profiles: unlimited scheduling for Feed, Stories and Reels, direct-message management, unlimited team members and Instagram Insights. The pages we read list no feature that designs the post, and its terms describe an Instagram-only service. Viuz gives you finished carousels, single images and Stories in your colors, fonts and handle, plans the week with a reason for each post, and posts to Instagram, TikTok, Threads, X, and LinkedIn (your personal profile).

Based on each product’s public pages, read in October 2026. "Partial" means it does part of this: Postgrain posts to Instagram only.

A scheduled file vs a designed post

A post you make, then schedule. You bring the finished images and caption, and Postgrain schedules them to Instagram.

When Postgrain is the better pick

You only post on Instagram

If Instagram is the only place you publish, the four other networks Viuz adds will not matter, and Postgrain does Feed, Stories and Reels scheduling without limits.

You answer direct messages

Postgrain manages direct messages next to scheduling. Viuz has a comment inbox but no direct-message inbox today.

You want to try without handing over a card

Postgrain says it does not ask for card details for its free trial. Viuz asks for a card up front and charges nothing for 7 days.

Common questions

Does Postgrain publish to networks other than Instagram?

Not on the pages we read: its terms describe a platform for managing Instagram profiles, and its price page lists Feed, Stories and Reels. Viuz publishes to Instagram, TikTok, Threads, X, and LinkedIn (your personal profile).

Does Postgrain design the posts?

No feature that designs the post is listed on its price page. You bring the images and caption. Viuz designs the carousel, single image or Story from a one-line brief, in your colors, fonts and handle.

How do the prices compare?

Its prices are in reais: for one profile R$ 29,90 a month, or R$ 20,83 a month on the annual plan (R$ 249,90 a year), with a discount as you add profiles. Ours are in the card above.

Can I try either one before paying?

Yes. Postgrain offers a free trial without asking for a card, which its terms of use put at up to 7 days. Viuz starts every plan with a 7-day trial: your card goes on file, nothing is charged for 7 days, and you get 10 generated posts rendered in your brand.
