## Claude

Claude is Anthropic's flagship AI assistant, renowned among software engineers, writers, and enterprise analysts for its natural prose, low hallucination rates, and sustained agentic execution. While the legacy directory slug still references 2023's 'Claude 2', both the Claude 2 and Claude 3/3.5/3.7 generations have been fully retired. As of late 2026, claude.ai runs on the Claude 5.5 generation—led by Claude Opus 5.5 (released September 2026), Claude Sonnet 5.5 for rapid everyday tasks and coding, and Claude Haiku 5.5—supporting up to a 1-million-token context window, 128K output tokens, and adaptive extended thinking.

Inside the web, desktop, and mobile apps, Claude functions as a full production workspace rather than a simple chat box. Users organize persistent knowledge bases with custom instructions in Projects, render and edit live React applications, SVGs, mermaid diagrams, and formatted slide decks side-by-side in Artifacts, and connect external SaaS tools via the open Model Context Protocol (MCP) and native web search. Paid subscribers also gain access to Claude Code—Anthropic's terminal and IDE agent capable of autonomous multi-file engineering across entire codebases—and Claude Cowork for collaborative enterprise task execution.

Anthropic structures Claude's 2026 pricing around compute capacity and team governance. The Free tier offers daily access to Sonnet 5.5, while Claude Pro ($20/month or $17/month billed annually) unlocks Opus 5.5, extended thinking, Projects, and entry-level Claude Code access. Heavy individual builders can upgrade to Claude Max at $100/month (5x Pro capacity) or $200/month (20x Pro capacity), while organizations can mix Team Standard seats ($20/seat/month annual) and Team Premium seats ($100/seat/month annual with 5x capacity and full Claude Code access) or adopt usage-based Enterprise contracts with audit logs and SCIM.

**Pricing & Plans:** Free tier ($0); Claude Pro at $20/mo ($17/mo billed annually at $200/yr); Claude Max at $100/mo (5x Pro usage) or $200/mo (20x Pro usage); Team Standard at $25/seat/mo ($20/mo annual) and Team Premium at $125/seat/mo ($100/mo annual); Enterprise from $20/seat/mo + API usage.

- **Claude 5.5 Model Family & Adaptive Thinking:** Combines frontier Claude Opus 5.5 and high-speed Sonnet 5.5 with configurable extended thinking, up to 1M-token context windows, and 128K-token outputs.
- **Claude Code & Claude Cowork Included on Paid Plans:** Pro, Max, and Team Premium plans bundle Claude Code for autonomous command-line software engineering, test execution, and repository-wide refactoring.
- **Interactive Artifacts & Document Generation:** Renders live interactive web apps, visualizations, spreadsheets, and formatted PowerPoint decks in a dedicated workspace panel alongside the chat.
- **Projects & Model Context Protocol (MCP):** Grounds conversations in shared project knowledge bases and connects directly to local filesystems, GitHub, Slack, and internal databases via MCP.
- **Constitutional AI Safety & Enterprise Governance:** Trained on Anthropic's updated 2026 Constitution with strict privacy guarantees, SSO, SCIM provisioning, and HIPAA-ready healthcare configurations.

**Strengths:** Top-tier coding, bug-fixing, and agentic planning performance powered by Claude Opus 5.5 and Sonnet 5.5; Natural, nuanced writing style that avoids the repetitive clichés common in competing LLMs; Claude Max ($100/mo 5x and $200/mo 20x) and mixed Team Standard/Premium seats provide clear scaling for heavy Claude Code users; Open Model Context Protocol (MCP) ecosystem enables deep, standardized connections to local tools and enterprise data

**Limitations:** No native photorealistic image or video generation inside claude.ai (limited to SVGs, code charts, and diagrams); Free tier does not include Claude Code and hits 5-hour rolling message limits quickly during long-context chats; Pro users ($20/mo) who rely heavily on Opus 5.5 or Claude Code can still exhaust their 5-hour rolling window and require Max ($100/mo)

## 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
