## 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)

## StackAI

. What StackAI is

StackAI is an enterprise AI agent platform aimed at IT and enterprise architecture teams. It provides the building blocks to turn a manual, time-consuming process into a working agent in minutes: a visual canvas for composing agents and multi-step flows, modules for storage, vision, text-to-speech and speech-to-text, and code steps in Python or JavaScript when you need custom logic.

Agents are only as useful as the systems they can touch, so the platform ships with 500+ enterprise integrations that let an agent read, write and execute tasks inside your existing CRM, ticketing, document and collaboration tools. Knowledge bases can be grounded in your own material through document upload, web scraping, Google Drive and Notion connectors, with readers for PDF, Word and PowerPoint. Because it is model-agnostic, each step can route to whichever LLM performs best for that job.

Governance is the differentiator. StackAI is certified to SOC 2 Type II, HIPAA, GDPR and ISO 27001, offers SSO, access control and audit logs, and supports human review at critical decision points. It can run multi-tenant, in your VPC or fully on-premise. The company announced that it has been acquired by Asana, adding human-agent workflow management to the picture. Pricing is a $0 Free plan with 500 runs per month, 2 projects and 1 seat, and a custom Enterprise tier for teams that need unlimited scale, dedicated engineers and regulated deployment options.

**Pricing & Plans:** StackAI has a $0 Free plan that includes 500 runs per month, 2 projects and 1 seat with community support. The Enterprise tier is custom-priced and includes a custom number of runs and seats, unlimited projects, all features and data loaders, dedicated infrastructure and solution engineers, on-premise and VPC deployment, access control, SSO, and SOC 2 / HIPAA / GDPR compliance.

- **No-Code Agentic Workflows:** Assemble agents and multi-step flows on a visual canvas with modules for agents, storage, vision, text-to-speech and speech-to-text, then add Python or JavaScript logic when you need it.
- **500+ Enterprise Integrations:** Connect agents to 500+ enterprise systems so they can read, write and execute tasks inside your CRM, helpdesk, document stores and collaboration tools.
- **Knowledge Bases and Data Loaders:** Ground agents in your own material with document upload, web scraping, Google Drive and Notion connectors, and document readers for PDF, Word and PowerPoint.
- **Security, Governance and Deployment Choice:** Deploy in multi-tenant cloud, your own VPC or on-premise, with SSO, role-based access control, audit logs and human review at critical decision points.
- **Model-Agnostic LLM Routing:** Choose the best-performing model for each step of a workflow instead of standardising on a single provider.
- **Ready-Made Agent Templates:** Pre-built agents for SOW intake, service desk replies, anti-money-laundering screening, call compliance extraction and internal L&D Q&A.

**Strengths:** Visual no-code builder gets agents from process to production quickly; 500+ enterprise integrations let agents act inside existing systems; Model-agnostic routing across leading LLMs; SOC 2 Type II, HIPAA, GDPR and ISO 27001 certifications

**Limitations:** Advanced capabilities such as on-prem, VPC deployment and SSO are Enterprise-only; The free plan is tight at 500 runs per month, 2 projects and a single seat; No public self-serve mid-tier pricing between Free and Enterprise; Enterprise focus means more setup and governance overhead than a lightweight automation tool
