Getting started
The Studio tools

How billing works
Credits are charged avant each generation. If the AI hits a technical error, your credits are automatically refunded. No credits are lost if there is a server problem.

AI automatically extracts title, date, time and priority. Dated tasks appear in the calendar. Filter by status: all, in progress or done.

FAQ
How do I connect my YouTube channel?
Go to Account → YouTube section and click "Connect YouTube". Secure login via OAuth 2.0.
Do my credits expire?
Credits bought in packs never expire. Each purchase is a one-time payment.
Puis-je utiliser Postvanta sans credits ?
Yes! Scheduling, the calendar, tasks, drafts and media uploads are completely free. Only AI Boost (6 credits), content generation (1 credit) and publishing (1 credit) consume credits.
How does AI Boost work?
Boost analyses your content and generates an optimised title, SEO description, relevant tags and an audience estimate. Cost: 6 credits.
Is automatic publishing available?
For YouTube, yes. For TikTok and Instagram, posts are drafts for now.
How do tasks work?
Write in plain language (e.g. "Tuesday 3pm film the video") and Postvanta automatically extracts the title, date, time and priority. Free.
