## 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

## Superhuman

Superhuman began as a famously fast email client and has expanded into a broader AI productivity suite. Today it spans Superhuman Go, an assistant that lives inside the apps and tabs you already use with inline suggestions and context-aware chat; Superhuman Mail, its email app with auto drafts, split inbox, auto labels, and auto archive; and Superhuman Docs, a collaborative workspace for documents, tables, data, and workflows.

A large part of the platform is built around agents. You can describe a task in chat or use a visual builder to create an agent, then share it with teammates or publish it to a company directory. Pre-built agents cover common knowledge-work jobs such as preparing for meetings by pulling relevant emails, notes, and docs, turning meeting notes into recaps for each owner, checking claims against company data, and humanising AI-generated text. Superhuman also sits inside the wider Superhuman Platform alongside Grammarly and GPTZero.

Superhuman is a paid product aimed at individuals, teams, and enterprises. The suite integrates with Gmail, Google Calendar, and many workplace tools, and the enterprise tier adds administration and security controls. For exact plan tiers, seat pricing, and included features, check the official pricing page, since packaging has changed significantly as the product has grown beyond email.
