POST-BASE is an AI-native social media command center. Compose once, let AI generate captions, images and short-form video, then schedule and cross-post to 9 platforms from a single dashboard.
POST-BASE brings content creation, AI generation, scheduling and analytics into one tab. Write a post once and publish it to TikTok, TikTok Business, Instagram, LinkedIn, Facebook, YouTube, Pinterest, Bluesky and X — with per-platform text tweaks and multiple accounts per network. What sets it apart from traditional schedulers: built-in AI UGC video generation, AI image generation, and AI caption writing tuned to each platform. Plan a week on a drag-and-drop calendar, then track reach and engagement across every account.

What do DR4, DR3 and the model difference mean?
DR4:
Ahrefs' newer model. It gives more weight to links from sites with organic search traffic and rates a subdomain on its own links.
DR3:
The previous model, shown in the Ahrefs app until 1 December 2026.
Model difference:
DR4 minus DR3 for the same domain. The models calculate differently, so this is not growth or a drop; the “since” lines compare each model with itself.
