## AIWriteBook

AIWriteBook targets authors who want AI assistance without losing authorship. Instead of dumping a generic first draft on the page, the platform asks you to define your premise, build characters and structure your outline, then use a writing-style profile trained on your own prose so chapters stay consistent with how you actually write. A manuscript import feature lets you bring in an existing DOCX draft and have the tool map characters, plots and subplots into its project structure.

The tool covers the full production pipeline. Beyond drafting, it offers chapter-by-chapter AI chat and editing suggestions, grammar and style checks, illustration generation, a cover maker, professional formatting and a KDP publishing assistant with category research. A Book Translation module supports publishing in other languages, an Author Public Page gives you a landing page, and the Audiobook Studio converts a finished manuscript into a narrated audiobook.

Pricing runs on monthly credits with four tiers — Free, Plus, Pro and Ultra — with discounts for annual billing, plus a one-time option. The free tier covers roughly twelve pages of output, while higher tiers add explicit content support, non-fiction workflows, translation, audiobooks, visual books and book-series management. Ultra adds bring-your-own-API-key access to a broader model catalogue and priority support.

**Pricing & Plans:** Freemium with a permanently free tier (100 credits, about 12 pages). Paid plans are Plus at roughly $12/month, Pro at roughly $30/month and Ultra at roughly $120/month when billed yearly, plus a one-time purchase option. Credits reset monthly and the platform advertises a 7-day money-back window.

- **Voice-matching style engine:** Train the AI on samples of your own writing so generated chapters, dialogue and narration follow your established tone and quirks rather than a generic literary default.
- **Manuscript import and project mapping:** Upload an existing .docx draft and let the platform parse characters, plots and subplots into structured fields, which is useful for finishing a long-stalled project.
- **Chapter writing with inline AI editing:** Draft chapter by chapter, then ask for targeted rewrites or alternatives with explanations, so you keep creative control over what actually stays on the page.
- **Cover maker, formatter and KDP assistant:** Generate a cover, lay out the interior to print specifications and export files sized for Amazon KDP and KDP Print distribution.
- **Audiobook Studio and translation:** Convert a finished manuscript into a distributed-ready narrated audiobook and translate books into other languages for wider reach.

**Strengths:** Covers writing, editing, illustration, cover, formatting and KDP distribution in a single workflow instead of stitching tools together; Style-training and manuscript import make the AI output sound like the author rather than like a generic content generator; Transparent credit-based pricing with a genuinely usable free tier and an audiobook and translation path on higher plans; Strong public review volume on Trustpilot, AppSumo and Capterra, with 4.7/5 average reported on the site

**Limitations:** Credit consumption is tied to output length, so long manuscripts push you toward the higher tiers quickly; The breadth of features means a real learning curve before the workflow feels efficient; Audiobook narration, translation and visual books are gated behind Pro and above, not available on the entry plans

## CielChan (phasma.ai)

CielChan is a local-first desktop companion rather than a web chatbot. Everything — conversation, memory, and voice — runs on your own PC, so there are no accounts, no API keys, and no subscription. The free version covers voice and text chat, companion memory, and an animated avatar with lip sync. The Plus tier, a one-time payment, unlocks system and audio awareness, advanced voice options, custom VRM avatars and models, multiplayer rooms, a TXT/EPUB book reader, minigames, and local vision for images and screenshots.

Beyond conversation, CielChan bundles utility: timed focus sessions, quick tasks and notes, reminders, ambient soundscapes, and bridges into live-stream chats on TikTok, YouTube, and Twitch. She can react to whatever you are doing on screen with subtle contextual comments, and advanced users can load custom GGUF models to control how she thinks, plus swap in their own VRM avatars. Multiplayer shared spaces let users and companions chat, interact, or run debate sessions together.

Two things are worth stating plainly for anyone who arrived here expecting the older product. First, this is a Windows application with meaningful system requirements (Windows 10/11, 8–16 GB RAM, around 28 GB of disk space), packaged as a download rather than a browser tool. Second, the phasma.ai domain formerly hosted Phasma, an AI writing and coding editor for document processing, translation, and summarization; the site now presents CielChan instead, and it is unclear whether Phasma is still maintained elsewhere.

**Pricing & Plans:** Free version available (voice and text chat, memory, animated avatar, no setup). CielChan Plus is a one-time $7.99 purchase (current version shown as 1.9.7) unlocking system/audio awareness, advanced voice options, custom VRM and model support, multiplayer rooms, book reader, minigames, and local vision. No subscriptions. Free version also distributable via itch.io, with Plus available on Steam or itch.io.

- **Offline voice and text conversation:** Natural two-way voice chat plus full text chat, all processed locally on your PC with no accounts, API keys, or data leaving your machine.
- **Persistent memory and evolving personality:** Ciel remembers who you are and your past conversations, becoming more familiar the more time you spend together.
- **Animated VRM avatar with context awareness:** An expressive avatar with emotions, gestures, and lip sync that optionally reacts to your apps, media, and activity with subtle comments.
- **Productivity and companion tools:** Focus sessions, quick tasks and notes, reminders, ambient soundscapes, and a TXT/EPUB book reader with narration — plus minigames like Tic-Tac-Toe.
- **Live chat bridges and multiplayer rooms:** Connect to TikTok, YouTube, Twitch, and Discord chats so Ciel can interact with your live audience, and join shared rooms for companion interactions or debates.

**Strengths:** Runs 100% offline with no accounts, API keys, or subscriptions — strong privacy posture; One-time $7.99 Plus upgrade with a genuinely usable free tier; Rich feature set beyond chat: focus tools, book reader, stream bridges, local vision, custom models; Extensive customization through custom GGUF models, VRM avatars, and personality controls

**Limitations:** Windows-only and fairly demanding (around 28 GB of storage, 8–16 GB RAM); Several headline features (system awareness, custom models, multiplayer, book reader) require the paid Plus tier; This domain previously hosted a different product (Phasma writing/coding editor), which makes older listings misleading; Heavy local AI inference benefits from a dedicated GPU for best performance
