PostOnce
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).
