Inkbreaker is a deliberate practice platform for writers. You complete short, targeted exercises, get feedback on your prose metrics, and track your skill progress over time. Think of it as a gym for writing craft, not a tool that writes for you.

No. The engine is fully deterministic. Same input, same output, every time. Your writing is never sent to a language model and never used for training. The only AI in the product is a content moderation filter that flags unsafe submissions before they reach the community.

Each exercise gives you a prompt and a constraint. You write directly in the editor and submit when you're done. The same engine that powers Prose Grade then scores your submission against benchmarks for your writing type. You earn XP toward specific skills, and your report card updates automatically.

If you submitted the same text twice, the scores should be identical. The engine is deterministic. If the numbers changed, the text changed. Check whether autocorrect, smart quotes, or a small edit affected your submission.

Every metric has a description on the submission result page. Click the info icon next to any metric for the methodology note and the research citation behind it. The /why page covers the engine end to end if you want the long version.

Skills are specific craft abilities like Hook, Tension, or Clarity. Each exercise targets one or more skills. When you submit, you earn XP toward those skills. Enough XP moves you up through six levels: Apprentice, Developing, Practiced, Skilled, Refined, and Master.

Prose Grade is a free tool that runs the Inkbreaker analysis engine on any passage you paste in. No account needed, nothing saved. It shows you readability, sentence variety, vocabulary range, passive voice, adverb density, and more, scored against benchmarks for whichever writing type you select.

The queue matches your request automatically with writers whose skill focus and XP in your genre fit your piece. You don't pick your reviewer and your reviewer doesn't pick you. Each request fans out to several candidates at once so you aren't waiting on one person.

The queue shows where your request sits. If it says "Finding a match," the system keeps looking and adds new reviewers to the pool as they become eligible. Requests stay open for up to two weeks. After that we mark the request unmatched and you can try again.

Yes. The reviewer's username is shown when feedback is delivered. Peer feedback on Inkbreaker is not anonymous. Writers who consistently leave specific, helpful feedback earn a Trusted Reader marker on their profile.

Rate it honestly using the two questions on the feedback page. Was it specific to your piece? Did it help you see something you'd missed? Your rating shapes who the queue surfaces in the future. If feedback was abusive or violated the community guidelines, use the report button.

Free includes the full editor, every exercise tier (beginner through experienced), full prose metrics on every submission, XP and skill progression, peer feedback, your Report Card overview, publishing, and the community. Pro adds metric history and trend analysis across submissions, advanced writing modes for poetry, screenwriting, technical writing, and copywriting, series, version history, folder organization, and export. Pro is $9 a month or $65 a year. Your first 30 days are Pro automatically. No credit card required.

Free accounts can submit three exercises per day. The count resets at midnight UTC. Quick Writes count the same as full exercises. Pro is unlimited.

Your Report Card tracks your progress across all the exercises you’ve completed. The Overview tab shows your skill progression grouped by writing type. The Analytics tab (Pro) shows deeper metric trends, domain progression, and benchmark comparisons over time.

Fiction, Nonfiction, Poetry, Copywriting, Journalism, Technical Writing, Screenwriting, Blogging, and Worldbuilding. Each type has its own skill set and benchmark targets, so your feedback is calibrated to what good writing actually looks like in that domain.

Exercise submissions are saved to your account and visible only to you by default. Pieces you publish are visible publicly on your profile. Drafts are never public. Nothing you write is used to train AI models. See our Privacy Policy for full details.

You can delete your account from your account settings page. Deleting your account permanently removes all your data including submissions, pieces, and skill progress. This cannot be undone.

Go to Billing in the nav menu. You can cancel your subscription there at any time. You'll keep Pro access until the end of your current billing period.

No. Your first 30 days are Pro automatically, no card required. You can add a payment method any time before the trial ends if you want to keep Pro after.
