Chat33 is an audited TikTok Content Posting partner. Videos up to 4GB and photo carousels publish directly to your profile, in the same queue as Instagram, YouTube, X, LinkedIn, and Facebook.
Free plan available · No credit card required
Big files, photo posts, and the consent screen TikTok requires, without leaving the composer.
Publish straight to your profile, or drop the video into TikTok's drafts and finish it in the app. Both are one toggle in the composer, not two different products.
Anything over 500MB is split and sent through TikTok's chunked upload automatically. No proxy in the path, no timeout halfway through a long render.
Up to 35 photos in a single post. Images TikTok won't accept get converted before upload instead of failing on you at the last step.
The dashboard is one way in. There's also a REST API, an n8n node, and an MCP server, so an editing pipeline or an AI assistant can publish for you.
Checked before the upload starts, so a post never fails halfway through for a reason you could have known.

Videos over 500MB switch to TikTok's chunked upload on their own. You pick the file; Chat33 picks the route.
TikTok has strict requirements for third-party publishing. Rather than leaving them to you, Chat33 reads them from your account and enforces them as you type.
Your real options
Privacy levels and duet, stitch and comment availability come from your own TikTok account, not a hardcoded list.
Commercial disclosure
Flag your own brand or a paid partnership, and the post carries TikTok's disclosure label.
AI-generated label
Mark a video as AI-generated and it goes out with TikTok's AIGC label attached.
Checked at publish time
A scheduled post revalidates against your account before it goes out, so a changed setting fails loudly, not silently.
Authorize once with your TikTok account. Chat33 refreshes the token on its own, and tells you if the connection ever needs your attention.
Chat33 reads your account's real options from TikTok, so you only ever pick a privacy level, and comment, duet or stitch setting, your account actually allows.
Post now, or put it on the calendar next to your Instagram, YouTube, X and LinkedIn posts and let it go out on its own.
Render, upload, and schedule without a person in the loop.
Connect your account and queue your first video in minutes.
