NIBB — a writing gym for your brain
You send your body to the gym. Where do you send your brain?
What this is
One prompt appears each day. You write on it for ten minutes. There is only one prompt on earth that day, so someone in Seoul and someone in Nairobi answer the same question. When you finish, the square opens and you can read what everyone else wrote.
We do not fix your writing
NIBB never rewrites a sentence for you. It only shows you where a reader snags. The plainness score is computed by rules inside your browser — it is never sent to a server, and no AI is involved. It works with the network off.
What is missing on purpose
No likes, no stars, no ranking, no view counts, no comments. There is one mark: ◆ — a single sentence a reader chose to keep.
Price
The first three days are free. After that it is $14.89/month for one person, $39.89/month for a family of up to four. Your card never touches our servers; Polar handles payment as merchant of record.
