We've shipped first-class comments support in the API, so AI agents can now read, write, and resolve comments on your drafts.

 Ask an agent: "Show all my drafts with open comments." Have it resolve the basic copy fixes and surface the editorial decisions worth a human eye.

. You leave a comment: "Hook is too soft." An agent replies in the thread with two rewrite options. You pick one. The edit applies. The thread resolves.

. Set up an agent to review each new draft and leave comments on weak hooks, factual claims, voice mismatches, repetition. You could trigger this with a tag like Agent Review.

/v2/social-sets/{social_set_id}/drafts/{draft_id}/

: list threads on a draft. Filterable by status and platform.

: create a span-anchored or post-level thread.

PATCH /comment-threads/{id}/comments/{comment_id}

DELETE /comment-threads/{id}/comments/{comment_id}

If using our MCP via Claude or ChatGPT, you're already up to date.

If using our Skill, ask your agents to self-update the typefully skill.

Comments API for agents

You can now choose who can reply to X posts published with Typefully.

Keep replies open to everyone, or limit them to accounts you follow, accounts you mention, verified accounts, or subscribers.

Use the new reply settings before publishing to decide what kind of conversation you want around each post.

Choose Who Can Reply to Your X Posts

Typefully is now available in Claude's official connector directory.

Claude can work across every account in your Typefully workspace.

 It can turn notes and ideas into drafts for all your platforms, schedule or queue posts, pull analytics, and work through comments.

Everything happens through Typefully, so your workspace, permissions, drafts, and publishing workflow stay in one place. Every draft lands in Typefully, ready for you to review and polish before it goes out.

The connector is available to all Typefully users. 

Typefully Is Now an Official Claude Connector

High-resolution videos posted to X through Typefully now publish at full 1080p instead of getting compressed to 720p.

This applies automatically as long as the X account you're publishing to has an active X Premium subscription. No settings to change, just upload your video and publish as usual.

1080p Video Publishing on X

 to show every social set in your workspace at once. Your brand account, the founder's account, your teammates, all in one view.

This becomes the "who says what and when" view. If your team ships content together, the whole plan finally lives in one place.

Here’s a full walkthrough of the new experience: 

It also introduces a highly requested state: 

Drafts with a date and time on the calendar that will not publish until you or the account owner confirms them.

So now you can sketch out your week first, then confirm each post when it's ready.

For teams, this is how a launch comes together: plan the brand post, the founder's take, and the employee amplification on the same day, then let each person confirm their own.

You can focus the calendar by social set, team, campaign, status, tag, or platform, so a busy month can become one launch, one campaign, or everything waiting for review.

To make it easier to get your work done in Typefully, we’ve redesigned the navigation into three modes in Typefully. 

New Calendar for Teams and Planned Drafts

Notes are great for quick ideas, links, quotes, and smaller updates around your longer posts.

Now they can live in the same calendar as the rest of your social content, so launches, follow-ups, and everyday posts are easier to plan together.

To get started, add Substack Notes as a new platform in your social set.
