About the AI assistant

Try asking: "Write 3 Farcaster posts about our weekend offer, check them against the Farcaster rules and schedule them for Friday at 10 am." It checks things like this first: Max 320 bytes of text (emoji and some letters use more than 1 byte). Up to 2 photos or videos, added as links. Optional channel in Settings. Follow-up comments become replies.

Tips for Farcaster

  • The limit is 320 bytes, not characters. Emoji and some letters use more than 1 byte, so check the counter.
  • Add up to 2 photos or videos. They are added as links.
  • Cast into a channel by adding its id in the settings, without the slash.
  • Postozo posts through Neynar with your own signer. Create it in the Neynar portal and approve it in the Farcaster app.

Short enough for the byte limit, with a clear ask. This is sample text to show the format, not a real customer post.

Checklist before you schedule a Farcaster post

  • The text is under 320 bytes for Farcaster.
  • No more than 2 photos or files are attached.
  • The first comment or thread parts are written, if you want them.
  • The channel sits under the right customer, so approval rules apply.
  • A time is picked, or the post uses the next free slot.

How approval, AI and reports work on Farcaster

Approval. If the Farcaster channel belongs to a customer with approval turned on, every post waits for a yes. The client sees a preview on a review link and can approve, ask for changes or comment. A post that is changed after approval goes back for a new yes.

AI. The AI assistant can fit a post to Farcaster, keeping it under 320 bytes, in your brand voice. It can also translate it, suggest a first comment and write alt text for pictures. Nothing changes until you accept.

Analytics. Farcaster shares results with apps like Postozo, so you can see numbers for each published post on the analytics page. Links in your posts can also be shortened to count clicks.

Bulk upload. Plan many Farcaster posts in a spreadsheet and upload them as a CSV file with bulk upload: up to 500 lines, each checked against Farcaster's rules before anything is created.

Client reports. Farcaster numbers go into client reports you share as a link, save as a PDF or email every week or month.

Client accounts. A client can connect their own Farcaster account from a client connect link, filling in Signer UUID, Neynar API key on the link page, so no password changes hands.

Check a draft against the Farcaster limit with the free Farcaster character counter, or count for every network at once with the social media character counter.
