Start writing

A sentence the writer typed, “Lisa looked at her watch and crossed the street.”, is selected and sent to Describe. The proposal keeps it word for word and adds detail around it: “The rain had thinned to a mist that hung under the streetlights. Lisa looked at her watch and crossed the street. Ten past nine. Tom had said nine, and Tom was never late.” Describe, 9 to 33 words, 24 added; the writer accepts it.

Beside it, Lisa stands under a streetlight in light rain on Mercer Street, looking at the watch on her raised wrist, beside Café Mercer with its shutter half down; the café clock reads ten past nine.

See it work.

The ProseSpun writing page: the writer selects their sentence, Describe proposes detail around it with the additions marked in mint, and after Accept the paragraph keeps the sentence word for word.

The ProseSpun writing page: a // beat under the writer's line. Draft proposes three sentences and the writer drops one and keeps two; Compose proposes a plan of three blocks, the writer reorders it, and each block is written and accepted in turn.

The ProseSpun writing page: the writer types a sentence naming the depot, the deck at the foot of the page offers a drafted card for it, and after Add the depot's mention becomes a card link.

Questions

What is ProseSpun?

ProseSpun is a fiction writing app for people with more story than sentences. You write a line the plain way, select it, and ask for more: Describe adds detail around it, Dialogue writes the spoken lines a moment needs, Rewrite says it another way. You see exactly what changed before anything touches your page.

Does ProseSpun write my story for me?

No. You write the story; ProseSpun proposes. Every suggestion arrives with the changes marked and the word count before and after, and nothing is added to your page until you accept it. You can also discard it or try again.

Do I need to be a good writer to use it?

No. ProseSpun is built for people who have ideas but aren't sure of their sentences. Write it plain, keep what reads better. Describe keeps your own sentences word for word and adds detail around them, so your line is never lost.

How does it keep a long story consistent?

Every person, place and thing your story names gets a card with a summary, traits and the other names the prose uses. ProseSpun drafts cards from what you write and waits for you to add them, keeps summaries of every scene and chapter, and tracks what is true of each character as of the scene you're in.

Is my writing private?

Your stories are private to your account and are not used for advertising. Deleting your account deletes them. The privacy page says exactly what is stored and why.

How do I start?

Sign up with an email address, name a story and start writing. You don't have to set anything up first: cards fill in from what you write.
