cometpost

Live on Threads and Instagram · YouTube, TikTok and X coming soon

Social scheduling your AI agent can use.

cometpost lets an AI assistant draft, schedule and publish your posts through scoped credentials and an MCP server. You can require that it only creates drafts for you to approve. Prefer to do it yourself? There is a normal dashboard composer too.

API & MCP

Let your AI agent do the posting

cometpost exposes a public HTTP API and an MCP (Model Context Protocol) server. That means an AI assistant you already use can draft, schedule and publish through your connected accounts, with your authorisation, instead of handing you text to paste somewhere else. Both are included in every paid plan.

MCP server

Point an MCP-capable client — an AI assistant, an IDE assistant, your own agent — at cometpost and it gets typed tools for scheduling and publishing. No scraping, no browser automation, no sharing your platform passwords with a bot.

Public HTTP API

A REST API covering the same operations as the interface: list connected accounts, create a draft, set per-platform overrides, schedule, check status, cancel. Scoped API keys, so a key can be limited to the accounts and actions you choose.

You stay in control

Agent access is a credential you issue and can revoke. When you create it you decide whether the posts it creates can be scheduled or can only be saved as drafts that you approve first, and which accounts it can reach.

Within platform rules

Agent-scheduled posts go through exactly the same official APIs and the same platform permissions as posts you make by hand. Automation is not a way around a platform's terms, and cometpost does not treat it as one.

Platforms

Where cometpost publishes

Each integration uses the platform's official public API and the permissions the platform grants for content publishing. Two platforms are live today. The rest are marked Coming soon and are not available yet. YouTube is built and waiting on Google's review; each of the others goes live only once that platform has approved our API access, which is the platform's decision, not ours.

  • Threads Live Text posts with images or video.
  • Instagram Live Feed images, carousels and Reels on Instagram professional accounts.
  • YouTube Coming soon (pending Google review) Video uploads.
  • TikTok Coming soon Video posts with a caption and privacy level.
  • X Coming soon Text and media posts.
What it does

One composer, no copy-paste

Posting the same thing to several places means several logins, several upload screens and several slightly different sets of rules. cometpost collapses that into a single workflow without pretending the platforms are identical. You can drive it from the dashboard or from an agent.

Compose once

Write the caption, attach the video or images, add hashtags and links in one editor. The draft is the single source of truth for every destination.

Tailor per platform

Override the caption for a single platform. Overrides are per-platform and optional — leave them alone and the shared version is used.

Schedule and forget

Pick one time for everything or a different time per platform. cometpost queues the post and publishes it on schedule — you do not need to be online.

See what happened

A per-post status log: published, pending, or failed with the reason the platform gave. Failed publishes can be retried without rebuilding the post.

Validate before you post

Each platform has its own limits on caption length, file size, aspect ratio and duration. cometpost checks the draft against them up front instead of failing at publish time.

Your accounts stay yours

Every connection is a standard OAuth authorisation you grant and can revoke from the platform's own settings at any time. cometpost only ever asks for the permissions it needs to publish what you scheduled.

How it works

Four steps, then it runs itself

  1. Connect your accounts

    Authorise cometpost on each platform you want to publish to, using that platform's own login screen. cometpost never sees or stores your platform password.

  2. Compose your post

    Upload your media and write your caption once, or let your agent create the draft. Choose which connected accounts this post should go to.

  3. Customise per platform

    Adjust anything that should differ, such as the caption. Anything you don't override stays as the shared version.

  4. Schedule it

    Publish now or set a time. cometpost handles the upload, the platform's processing delay and the retry if a platform is briefly unavailable, then records the result.

Pricing

Priced by connected accounts, not by posts

A Channel is one connected account on one platform. Plans differ by how many Channels you can connect. Posts are unlimited on every plan, and the public API and the MCP server are included on every plan, Free too. Prices are in US dollars and apply once paid plans open.

Who it's for

Built for people who publish the same thing in several places

Developers and agent builders

You want publishing as an API call or an MCP tool, not a browser window — and you want it to run on official platform APIs so it does not break or get you banned.

Solo creators

You make one post and it belongs on several platforms. You would rather spend that hour making the next one.

Small teams and agencies

A handful of accounts across several platforms, a content calendar, and a need to see what actually went out and what failed.

Status

Where the product actually is

cometpost is a young product. We would rather tell you plainly what works today than dress it up.

What is true today

  • You can sign up, connect accounts and publish to Threads and Instagram.
  • YouTube is built and waiting on Google's review. TikTok and X are coming soon. None of the three is available yet.
  • The Free plan is open now. Paid plans are not on sale yet; see Pricing.

What we are not claiming

  • No customer numbers, testimonials or case studies — there are none yet.
  • No press coverage or partner logos.
  • No integration is listed as live before the platform has approved our API access.
  • No mailing list. This website sets no cookies and uses cookieless, privacy-focused analytics that count visits without tracking you across sites.

FAQ

Questions we expect

Does cometpost read my messages or my followers?

No. cometpost requests the permissions needed to identify which account you connected and to publish content you have authored and scheduled. It does not read direct messages, does not export follower lists, and does not collect data beyond what the granted permissions require. This is set out in detail in the privacy policy.

Do you use my content to train AI models?

No. Content you upload or compose is used to publish that content to the platforms you chose, and for nothing else. We do not use customer content to train machine-learning models, and we do not sell or license it.

How do I disconnect an account?

From inside cometpost, or from the platform's own connected-apps settings. Revoking access there immediately stops cometpost from publishing to that account. Instructions for each platform are on the data deletion page.

What happens if a platform changes or revokes its API?

The integration for that platform stops working until it can be fixed, and we will say so. Platform APIs are outside our control; this is stated plainly in the terms of service rather than buried.

Is scheduling with a bot against the platforms' rules?

Publishing through a platform's official content-publishing API, with permission the account holder granted, is a supported use of those APIs. What is not allowed is spam, bulk duplicate posting, impersonation and working around rate limits — those are prohibited by cometpost's terms as well as by the platforms.

What will it cost?

Free is $0 for 2 Channels and 3 video uploads a month, with no card, open to the first 500 workspaces. Paid plans are not on sale yet. They will be Starter at $14 a month for 15 Channels, Growth at $29 for 50 and Scale at $59 for unlimited, with annual billing at two months free ($140, $290 or $590 a year). Posts are unlimited on every plan, and the API and MCP server are included in every paid plan. For early access to a paid plan, email hello@cometpost.app.

Where is my data stored, and can I delete it?

Account data and OAuth tokens are stored encrypted with our hosting and database providers. You can delete your account and all associated data at any time — the data deletion page gives the exact steps and our response time.
