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 responds in the comment 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.

Draft Comments API for agents

Your Substack Notes in Typefully can now mention people and include a video.

 and the first couple of letters of their name. Typefully suggests matching Substack profiles, and the person you pick gets linked when the note goes out.

 to a note, up to 15 minutes long. Substack takes either one video or up to 6 images per note, so the two can't be mixed.

Cross-posting from X or LinkedIn? Your video now comes along instead of getting dropped. If something doesn't fit in the note, like extra images, Typefully tells you what was left out before you publish.

Connecting Bluesky to Typefully no longer needs an app password.

, and you're connected. Typefully never sees your password, and you can revoke access from Bluesky.

, not just Bluesky's own servers. That includes self-hosted servers, providers like Eurosky, and custom-domain handles. If moving your account to another server broke your connection, you can reconnect it now.

Already connected with an app password? Your account keeps working, so there's nothing to do. If you reconnect it, you'll use the new sign-in.

Easier Bluesky Sign-In, Now with Custom PDS Support

 in the Writing Assistant sidebar. It reads every open comment together, revises the posts they point at, and tells you which comments it left for you, like questions only you can answer.

. Typefully updates your draft and resolves the comments those edits addressed.

Changed your mind? Undo brings back your original text and reopens every comment.

You can also ask the Writing Assistant to resolve specific comments, like "resolve Thomas's comments."

Address Feedback with Typefully's Assistant

You can now add polls to your LinkedIn, Threads, and Mastodon posts in Typefully, not just X.

Write a poll once and the options carry over to every platform in your draft that supports polls. Each platform keeps its own settings, like how long the poll runs. If you set up something a platform won't accept, like too many options or an option that's too long, Typefully flags it before you publish.

 the poll has its own question (up to 140 characters), 2–4 options (up to 30 characters each), and runs for 1 day, 3 days, 1 week, or 2 weeks.

 the post text is the question, with 2–4 options (up to 25 characters each). Polls run for 24 hours.

 the post text is the question, multiple-choice polls are supported, and option count, length, and duration follow your server's limits.

Polls are available on every plan, including Free. As on X, a post with a poll can't include images or video.

Polls on LinkedIn, Threads, and Mastodon

Quote posts are no longer just for X and LinkedIn. You can now quote posts on Bluesky, Mastodon, and Substack Notes too.

Paste the link to the post you want to quote into your draft.

Click the button on the link preview to convert it into a quote.

Quotes also work in thread finishers, so the last post in your thread can point readers back to the first.
