Everything you would do in Poplar, from the chat.
Poplar's writer drafts from your brand voice, past posts and strategy, and asks one question rather than invent a fact.
Save drafts, edit them, preview them as they will look, and see what is already scheduled.
The assistant shows the post and the exact time; nothing is scheduled until you confirm.
Send a draft to a teammate or client for approval, and see what is waiting on whom.
Ask how posts performed and which ones worked, from the numbers Poplar collects.
Read your Poplar strategy and the post ideas it has ready for you this week.

Does the assistant write the posts, or does Poplar?
Poplar does, when you ask for a post. Your assistant hands the brief to Poplar's writer, which uses your brand voice, the posts you have published, your strategy and what Poplar knows about your business. If a post would need a detail only you know, Poplar asks one question first instead of making it up.
Can it post without me?
No. Every post goes through Poplar's scheduler, and scheduling is two steps: the assistant shows you the post and the exact time it will go out, and nothing is scheduled until you say yes. If your workspace requires approvals, those still apply. You can take a post back off the calendar until it sends.
Which networks can it post to?
Every account connected in your Poplar workspace: LinkedIn (personal profiles and company pages), X, Instagram, Facebook, Threads, Bluesky, TikTok and YouTube.
What does it cost?
Connecting an assistant is included in every Poplar plan, with the same 7-day free trial. Your assistant's own plan is separate.
