Updated 8 October 2026.
Why choose Postdom over Sintra AI
- It makes the finished post. Postdom turns your website into ready-to-post videos, slideshows and single images in your brand, built from real clips and photos with native text boxes. Sintra's Soshie writes posts, scripts and strategy; its site does not say it makes video.
- It posts what you approve. Approved posts go out on official APIs to nine platforms, at set times in your time zone. Nothing posts until you approve it.
- It learns your taste and earns autopilot. Every approve, edit and skip shapes the next posts. Once 9 of your last 10 posts of one type are approved without edits, Postdom offers to post that type for you.
- A person on screen without filming. In Postdom's study of 2,138 TikTok posts, product brands' videos with their usual person on screen drew 2.51x their usual views, and videos with no person drew 0.42x. On paid plans, an AI persona is how Postdom puts the same person on screen in every video, with no camera.
- See it before you pay. Free makes 1 post a month from your own website, with no card. Sintra shows no free plan (Sintra pricing page, checked 8 October 2026).

Sintra counts credits shared across 12 helpers. Postdom counts posts, and a post only counts when you approve or schedule it. Sintra's price buys writing help across the business; Postdom's buys finished posts that go out for you. The two numbers do not line up one to one.
Making the content
Sintra AI: you ask Soshie in chat, and it writes post ideas, captions, scripts and strategy, finds trends and gives advice on your brand image. Its site does not say Soshie makes the video itself.
Postdom: social formats that already work on TikTok and Instagram. Your For You feed fills with finished posts built from real clips and photos with native text boxes, music and optional voiceover. The Create section has Videos, Slideshows, Single images and Remix.
Approval and posting
Sintra's pricing page does not describe an approval step. Its home page says Soshie can schedule social posts. Postdom lets you approve, edit or skip each post, and nothing posts until you approve it.
Postdom schedules what you approve at set times in your time zone, with quiet hours overnight. The AI label is on by default for TikTok, Instagram and YouTube posts.
Postdom posts to nine platforms in total. Videos go to TikTok, Instagram, YouTube, Facebook and LinkedIn. Slideshows go to TikTok, Instagram, Facebook and LinkedIn.
Where Sintra AI wins
- A lower monthly price on its 12-month plan: $15.60 a month for all 12 helpers, against Postdom's $39 Starter.
- Wider scope: helpers for email, customer support, sales, SEO and more beside social.
- A bigger customer base: its home page claims 40,000+ business owners in 100+ countries.
Postdom is still our pick for a small business that wants posts made and posted for it. Sintra helps you write; Postdom hands you finished videos, slideshows and single images in your brand and posts the ones you approve.
Where Postdom wins
- Finished short-form posts. Videos, slideshows, single images and remixes of trending formats, all in your brand and all made for TikTok and Instagram.
- Formats people save. In Postdom's study of 1,278 TikTok posts, photo slideshows drew 51 saves per 100 likes, 4.5 times the rate for videos. Postdom makes both.
- A consistent face, no camera. AI personas are on paid plans. You make one from 3 to 5 photos of yourself, or describe one, and every persona video carries the platform's AI label.
- Earned autopilot. Postdom offers to post a type without review only after 9 of your last 10 were approved without edits.
- Start free, no card. Free makes 1 post a month and connects 2 accounts on any platform. Sintra shows no free plan.
- API and MCP on every plan. Your own AI agent can post through Postdom's REST API and MCP tools, including from Claude and ChatGPT.

Sintra AI review
Our Sintra AI review, from its own site on 8 October 2026: Sintra is a bundle of 12 AI helpers that work from one shared memory of your business. Soshie is the social media helper. It writes post ideas, captions, scripts for Reels, TikTok and YouTube, X posts and social strategy, and it finds trends.
What it does well: a lot of help across the business for a low price on the 12-month plan, and one memory shared by every helper. What it does not show: finished video, a full list of platforms it posts to, or a free plan.
Who it suits: a business owner who wants a writing partner for many jobs. Who it does not suit as well: a small business that wants short-form videos made and posted without doing the production itself.
