Hey Sumo-lings,

Mykyta here from AIWriteBook. And a new update we did today, on 28.10.2026.

I read every review and question on this page. Two complaints kept coming back. Nonfiction chapters had facts you couldn't check, and some were just made up. One of you called it "the research trap", which stung because it was fair. The other one: "I know my stuff, I just can't get it into a book."

Here's what we built for both.

1. Internet research for nonfiction

Before, the AI wrote from what it already knew. That's where the invented facts came from. Now it reads before it writes.

- Click "Research my topic online" on the Details step. It reads about 20 real pages on your topic. Give it a couple of minutes.

- You see every source with its title and link. Don't trust one? Delete it. Don't like the batch? Hit "Search again".

- Chapters are written from those sources, and the reference list cites them (APA, with URLs). You can click through and check every claim yourself.

- Sources don't count against your 10-file upload limit.

- Free on your first book. After that it's 100 credits a run, and if it finds nothing usable you pay nothing. It runs on our keys, so BYOK won't make it cheaper.

2. Expert Book

For coaches, consultants, and anyone whose book is basically already in their head. One rule: everything in the book comes from you. It doesn't invent anything.

- Throw in what you already have: PDFs, Word docs, slides, a YouTube talk, a podcast episode, a call recording, messy notes.

- Then it interviews you, but only about the gaps your material doesn't cover. Voice or text, skip what you want. Takes about 15 minutes.

- You read the start of chapter one before you spend a single credit.

- Unlocking a book costs 2,500 credits, once. Everything after that is included for that book: every chapter, rewrites, the editor, print PDF and EPUB, cover, KDP keywords and categories, metadata, marketing copy.

- No material of your own? Use regular Nonfiction with internet research instead.

3. Book Editor

It's out of beta. It reads the whole manuscript first, so names, places and facts match from chapter 1 to the end.

- You get a 30-point review for your genre, an editor's letter, and a "fix this first" list.

- Line edits and proofreading come in one pass. Accept or reject each change.

- Got a Word file from somewhere else? Drop it in at /app/tool/book-editor.

- The first page is free. After that it's 15 credits per 1,000 words, charged once per book. Re-runs on that book are free.

Most of this came straight from this page and the public roadmap (aiwritebook.com/app/public-roadmap). Keep the questions coming, I answer all of them myself.

Hey Sumo-lings!

Mykyta here, co-founder of AIWriteBook. The three most requested things from this page and our public roadmap are all live now. Here is how each works.

1. Bring your own OpenRouter key (Tier 3 and 4)

The most asked question on this page, and the most upvoted roadmap item. We went with OpenRouter because one key gets you basically every model that exists, including new ones the day they appear.

• Left sidebar, "Your Own API Keys". Paste your key from openrouter.ai/settings/keys. We verify it live before saving, store it encrypted, and you can replace or remove it anytime.

• Chapters, outlines, covers, and chapter images run on your key.

• Any OpenRouter model can write your chapters: on the chapter step, open the model picker, expand "All other models", and search. We test the model against your key before you commit to it.

• A BYOK action costs a flat 1 credit instead of the full price (a chapter is normally 15+).

• If your key fails mid-generation (out of funds, rate limited), we fall back to our keys and charge the normal price rather than losing your chapter. Custom models are never silently swapped - generation stops and tells you.

• You can also add an ElevenLabs key for audio, which matters for the next one.

2. Audiobook Studio (Tier 2 and up)

Turns a book already on the platform into a finished audiobook. Your chapter text is the script - nothing to upload.

• Open /app/tool/audiobook, pick a book, choose from 25 voices (American, British, Australian, Swedish accents), each with a preview.

• Multi-voice: the Studio detects your characters and who speaks each line, proposes a cast, and you adjust it. Up to 10 voices per book, with optional automatic emotion tags.

• It renders chapter by chapter. If one paragraph comes out wrong, you re-record just that paragraph.

• Export: retail (-19 LUFS) or streaming (-14 LUFS) mastering, 128/192/256 kbps, as merged MP3 with chapter markers, ZIP of per-chapter MP3s, or M4B with embedded chapters and cover art. Everything runs on ElevenLabs v3.

• Pricing: 1 credit per 12.5 characters, x1.2 for multi-voice. No length cap. With an ElevenLabs key connected, a render batch costs 1 credit.

• Voices are English accents; non-English books narrate fine with them.

3. Your library, organized (every tier, free)

The top roadmap item by vote weight, asked right here too: series folders, categories, a way out of the single flat book list. The dashboard now has:

• Series: assign a book to a named series from the "..." menu on its card. It shows as one collapsible group in reading order with a number badge per book.

• Tags: create any tags via the "+" chip in the toolbar, assign as many per book as you want, filter with one click on the chips above the grid.

• Archive: hides old drafts without deleting them; a toggle brings them back. Archive is reversible, deletion is not - archive instead of deleting.

• Search by title, sort by newest, oldest, title, or progress.

• We ran a one-time pass that grouped books that obviously belong to the same series. Fixing a wrong guess is two clicks on the card menu.

Series here is visual organization; shared characters and locations across a series is its own roadmap item, open for votes now.

The public roadmap is at aiwritebook.com/app/public-roadmap - all three of these came straight off it. Keep voting, it clearly works on us.
