Feldar is a writing app for novelists. Your chapters, your scene plans and your story world live in one workspace, beside the page you are writing. When you want help, Feldar can suggest the next lines, rework a passage or give you a first read, and nothing changes in your manuscript until you accept it.
Free to start with 500 credits, no credit card. In your browser or on macOS.
Most novelists keep a book in pieces: the draft in one app, the plan on index cards, the world in a notebook, feedback in an email thread. Feldar keeps those pieces together, so the plan, the world and the prose can inform each other.
Every page in Feldar has an outline. Describe what happens next, choose how many scenes you want, and Generate scenes lays them out with a title and a short description each. Rewrite them, delete what doesn't fit, or add your own.
When the plan is right, write the chapter yourself with the scenes beside you, or press Draft Page for a first pass at the word count you set.
How scene planning works
Characters, locations, items, factions, plot beats and notes sit on one board as cards, joined by labelled links such as Part of, Causes or Opposes. Branch from a card to start a related one: a sister for your detective, the town where she grew up.
When Feldar helps you write, it draws on these cards, so its suggestions use the names, places and history you have already set down.
More about the Canvas
Select a passage and choose Polish, Deepen or Enhance, or tell Feldar what you want in plain words, like "Slow this down." The rewrite arrives in a card with the changed words marked. Apply it, or keep what you had.
At the end of a paragraph, Continue from here writes the next lines in blue. They stay only if you accept them. Paste a sample of your own prose into Voice & Style and the suggestions follow your rhythm rather than a generic one.
How Feldar's AI works for novelists
Lens, in Chat, gives your page six readers: Critic, Cheerleader, Poet, Editor, Plotter and Reader. Ask one of them, or let them debate and sum up.
Reader reactions takes the audience you pick, such as fantasy readers or a book club, writes a short reader report and marks the moments that landed, or didn't, in the margin of your manuscript.

Checks reads the page for five kinds of problem: grammar and spelling, clarity and readability, repetition and word choice, dialogue transitions, and point of view. Each issue is marked in the text with a suggested fix.
Opening Checks never touches your prose. You accept a fix, ask for another, or discard it.
