Schedule and publish to Nostr
Write once and send a note to your relays, now, on a date or through a queue. SPREVA checks the 8,000 characters and your media before it sends.
What you can publish
Notes
Text, optionally with up to 4 images or a short video, sent to your relays.
What SPREVA checks before it publishes
Every post is checked against these limits for each Nostr account you picked, in the editor and again right before it goes out, so a problem shows up while you can still fix it.
- Text
- 8,000 characters
- Media per post
- Up to 4 images or short videos in one note, mixed together
- Image size
- 25 MB per image
- Video size
- 200 MB per video
- Alt text
- 1,000 characters per image or video
Checked against SPREVA and Nostr's documentation: September 2026.
How connecting works
Nostr connects with the private key for your account, pasted once: an nsec1... key, or its 64-character hex form. There is no sign-in page to go through.
Add your own relays, comma or newline separated, or leave the field blank and SPREVA finds your relay list itself, or falls back to a small set of well-known ones. Your key is never shown again after you paste it.
What SPREVA adds
Photos and video hosted for you
A Nostr note carries no attachments of its own, so SPREVA uploads your images and video to a media host first and drops the link into the note, where any Nostr app can show it.
Hashtags, written or added
A #hashtag already in your text is picked up on its own. Add more that should not clutter the text itself, and they go out on the note too.
Alt text from your library
The description saved on an image or video in Media goes out as its alt text on Nostr, unless you set your own for that note.
No double notes after a timeout
If a relay's answer gets lost, SPREVA sends the exact same note again on retry, and a relay that already has it recognises it as the one it already has, instead of adding a second one.
And as on every network: its own text for any account, an approximate preview, publishing now, on a date or through a queue, and a retry for only the accounts that failed.
Questions about Nostr
Can I schedule Nostr notes?
Yes. Publish now, choose a date and time, or add the note to a queue that fills your next free slot.
Which relays does SPREVA send my notes to?
Your own, if you add them when you connect, or the ones SPREVA finds you already use. Leave the field blank for a small set of well-known relays instead. A note goes out to up to 8 relays at once.
Can I add hashtags to a Nostr note?
Yes, two ways: write #hashtag in your text, or add extra ones that will not show in the text itself. Both go out as hashtags on the note.
Does deleting a Nostr note remove it everywhere?
SPREVA asks every relay it sent the note to, to remove it, but a relay can keep its own copy anyway, and anyone who already saved the note keeps theirs too.
