Nostr scheduler: publish notes to Nostr on schedule

Post to Nostr without being online at the time. You connect with your Nostr private key; Postemi stores it encrypted, signs your notes with it and sends them to five public relays at the time you set. A Nostr key cannot be revoked, so use one you are fine sharing with Postemi.Beta: New in Postemi and not yet tested with many accounts. Tell us if something does not work.

  • 5 public relayseach note goes to all of them
  • nsec or hex keystored encrypted
  • 30 platforms and appsincluding Nostr, in one calendar
Works with any AI or agent

Signed with your key

Notes are signed as you, so they show on your profile in every Nostr app.

Public relays

Each note goes to relay.damus.io, nos.lol, relay.primal.net, relay.snort.social and offchain.pub.

Pictures as links

Pictures and videos are added to the note as links, which most Nostr apps show inline.

One calendar

Nostr sits next to your other channels, so nothing is planned twice.

Plan, schedule and measure your Nostr content from one place

Notes with pictures and replies, signed with your key and sent on schedule.

Frequently askedquestions

Is it safe to give Postemi my private key?
Postemi stores it encrypted and only uses it to sign your notes. But a Nostr key cannot be revoked: anyone who has it can post as you for good. Use a key you are fine sharing, for example a separate key just for posting.
Can I choose the relays?
Not yet. Postemi sends every note to the same five public relays.
What if no relay confirms a note?
Postemi reports it and does not send it again, because a relay may still have taken it. Check your profile before posting again.
Is there a free trial for Nostr?
Yes, every new account starts with a 7-day free trial. We ask for a card to start the trial, but we don't charge anything during it. After that the Basic plan is available from $19 a month, and you can cancel anytime.
