PostOnce
Claude connectorCommunityWrite, schedule and publish posts to Instagram, TikTok, YouTube, LinkedIn, X, Threads, Bluesky, Facebook and Pinterest, then check how they…
PostOnce lets Claude publish to your social media accounts through each platform's official API. Connect your accounts once in PostOnce, then ask Claude to post.
- Post one idea everywhere: Claude writes a native version for each account (length, first line, hashtags, format) and sends them in one request.
- Schedule posts or a whole content calendar, or save drafts to finish later.
- Publish images, carousels and video: Claude uploads the media and attaches it.
- Check delivery: each platform's status and live post URL.
- Set up automatic crossposting, for example every new Instagram Reel also goes to TikTok, YouTube Shorts and Facebook.
- See what's working: views, likes, comments, shares and saves for your TikTok, Instagram, YouTube and Facebook posts, compared with each account's usual numbers.
- Change or cancel a scheduled post.
Platforms: LinkedIn (profiles and company pages), Instagram (Business or Creator), TikTok, YouTube, X, Threads, Bluesky, Facebook Pages and Pinterest.
Nothing is published unless you ask. Sign in with OAuth; no API key needed. Requires a PostOnce account (free for 7 days, no card).
