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.
