In February 2026, Anthropic shipped something that mattered more than a model bump: plugins for Claude Cowork, its agentic workspace, with a legal plugin leading the release. Interest in Anthropic new AI tools — February 2026 legal plugin coverage above all — spiked for a simple reason: this was the moment Claude stopped being a chatbot with an API attached and started behaving like a domain specialist. Below is the release timeline, what each piece means if you are deciding what to pay for, and the third-party ecosystem that has grown up around the platform.
Anthropic new AI tools: February 2026 legal plugin timeline
The release only makes sense read as a sequence. Each step tells you something about where the platform is heading — and about whether the piece in front of you is a product, a packaging change, or a bet.
- February 2026 — Cowork gets plugins. Anthropic introduced plugins for Claude Cowork that bundle skills, connectors, slash commands, and sub-agents, so Claude can operate like a domain expert for a specific role or team. The legal plugin, with contract review among its skills, was the headline act.
- February through spring — adoption. By Anthropic's own account, legal professionals became the most engaged Cowork users of any knowledge-work function after the February launch.
- May 2026 — Claude for Legal. The single plugin grew into a full offering: twelve practice-area plugins (commercial law, corporate law, employment law, privacy, intellectual property, and litigation, plus tooling for law students and legal clinics) and connectors to more than twenty widely used legal platforms.
The pattern is the story: ship one vertical plugin, watch engagement, then expand hard where it lands. Legal happened to be first. If you work in another document-heavy field, the February release is a preview of how Anthropic will likely arrive in your industry too.
What the legal plugin is — and what it is not
It is not a standalone app with its own price tag. A Cowork plugin is packaging: a bundle of skills, data connectors, slash commands, and sub-agents delivered through the Claude platform itself. Turning Claude into a contract-review assistant means picking a Claude plan and enabling the plugin, not buying new software from a legal-tech vendor.
That framing matters for anyone evaluating tools right now. The announcement-level detail — agentic legal workflows, contract review, practice-area bundles — is public. Granular specifics such as per-plugin benchmarks are not something to shop on yet. The concrete, comparable numbers live one level down, in the platform's plans, which is where a real decision gets made.
The platform underneath: what Claude costs and carries
Claude spans advanced reasoning, vision analysis, code generation, multilingual processing, and API access, with a model lineup — Opus, Sonnet, and Haiku tiers — carrying a 200K context window. That context size is exactly what long-contract work leans on: a full agreement, its amendments, and the relevant policy can sit in a single conversation. For teams with compliance requirements, Anthropic runs on AWS and GCP, holds SOC 2 Type II certification, and offers HIPAA compliance options — the kind of checklist items a firm's IT review will ask about before any plugin gets switched on.
| Claude plan | Price |
|---|---|
| Free | $0 |
| Pro | $17/mo annual ($20 monthly) |
| Max | from $100/mo (5x or 20x usage) |
| Team Standard | $20/seat/mo annual ($25 monthly) |
| Team Premium | $100/seat/mo annual ($125 monthly) |
| Enterprise | $20/seat + API usage |
A solo reader curious about the legal-plugin story can start at $0 and see how Claude's plans and features stack up before committing anything; a firm evaluating Cowork for a whole practice group is realistically looking at Team or Enterprise seats. The lightest entry point of all is Claude for Chrome — a free way to put the assistant to work through natural-language instructions, reachable via the web or the API.
The third-party Claude ecosystem
Anthropic's own releases are only half of what shipped around Claude in 2026. A layer of independent tools has grown up around Claude Code and the browser, and several of them solve problems the official releases do not touch.
Claude Skills Hub — find skills instead of writing them
Claude Skills Hub is a curated third-party marketplace for Claude Code skills: modular extensions you browse, discover, and download rather than build yourself. Categories run from creative and dev work to design, productivity, communication, and office tasks, and the community can submit skills of its own. Concrete examples include comprehensive PDF manipulation (text extraction, document merging), creating and editing Word documents and PowerPoint presentations, testing local web apps with Playwright, and generating status reports or newsletters. If the February plugins showed what packaged expertise looks like officially, this directory is the community-run version of the same idea.
runCLAUDErun — put Claude Code on a schedule
runCLAUDErun is a native macOS app that automates Claude Code CLI commands: schedule tasks at specific times, at intervals, or in response to system events, without hand-writing cron jobs. Everything runs locally on the Mac and executes in the background, with task history and logs for review, plus automatic updates. Typical jobs are recurring code reviews, scheduled content generation, automated data-analysis workflows, and reports generated from a standing prompt.
Claudebin — share what a session actually did
Claude Code stores session data locally in a format that is not human-readable, which makes "look at what the AI did here" surprisingly hard. Claudebin, an open-source tool, exports full sessions — message threads, file reads and writes, bash commands, MCP calls — into navigable web viewers at a shareable URL. That turns a terminal session into something you can link in a pull request, embed in documentation, or resume on a different machine. Installation is a one-click plugin, fitting neatly into the same plugin vocabulary Anthropic introduced in February.
AIPex — automation in the browser you already use
AIPex is a free, open-source AI browser extension that adds automation to an existing browser instead of asking anyone to migrate to a new one. It covers natural-language control, tab grouping and management, and page-content interaction and data extraction — asking questions of open tabs, pulling summaries, running research across multiple sources. Pricing stays light: a $0 free tier, Basic at $4.49, and Standard at $10.
Which of these do you actually need?
The February 2026 legal plugin is the signal; the buying decision is more mundane. A legal team drawn in by the plugin story is really choosing a Claude Team or Enterprise seat and switching a capability on. A developer who lives in Claude Code gets more immediate value from the ecosystem layer: Claude Skills Hub for ready-made capabilities, Claudebin for making sessions reviewable, runCLAUDErun when the same prompts should run on a schedule. A reader who mostly wants AI to handle browser drudgery can skip the platform question entirely and start with AIPex at $0.
And if legal is not your field, the timeline is still worth remembering. Anthropic's play in 2026 — one vertical plugin in February, a full practice-area suite by May — is a repeatable motion. The next "legal plugin" moment will probably look exactly like this one, just wearing a different industry's name.
