Complete Guide to 85 Use Cases for Claude: Most Tasks Don't Need the Most Expensive Model

Overview of Claude’s Use Cases

Anthropic has recently organized and released 85 clickable Claude use case templates, spanning 12 categories including workplace, learning, finance, law, marketing, and research. Each scenario specifies the recommended model and necessary feature combinations (like web search, connectors, and extended thinking), allowing users to directly access the corresponding Claude conversation.

Model Usage Data

In the 85 official scenarios, the model usage distribution is as follows:

Model	Number of Scenarios	Percentage	Purpose
Sonnet 4.5	~50	60%+	Daily tasks
Sonnet 4.6	11	13%	Interactive visualization, education
Opus 4.5	~8	9%	Complex reasoning, legal finance
Opus 4.6	4	5%	High-difficulty cross-file analysis
Haiku 4.5	6	7%	Quick browser automation

This data reveals that over 60% of work scenarios can be effectively handled by Sonnet 4.5. The Opus series is only necessary for niche scenarios requiring deep reasoning, such as legal contract analysis and financial stress testing. In other words, if you primarily use Claude for writing documents, organizing information, or generating materials, there’s no need to invest in Opus. Instead, allocate your budget towards Connectors and Extended Thinking for greater productivity.

Overview of 12 Categories

The 85 scenarios are divided into 12 categories, covering nearly all task types a knowledge worker might encounter:

Category	Number of Scenarios	Typical Tasks
Workplace	17	Brand material generation, market research, progress reports, cross-tool daily reports
Personal Life	~8	Travel planning, personal budgeting, daily decision-making
Learning & Education	~8	Interactive course design, learning material generation
Finance	~5	Financial modeling, investment analysis, stress testing
Sales	~6	Competitive analysis, sales pitches, proposal comparisons
Legal	4	Contract review, compliance checks, clause comparisons
Research	~7	Literature review, data extraction, experimental design
Marketing	~8	Cross-platform content rewriting, SEO optimization, event planning
Life Sciences	4	Paper interpretation, clinical data analysis
Human Resources	5	Resume screening, interview question bank, onboarding processes
Browser Automation	6	Web data extraction, form auto-filling
Non-Profit	5	Grant applications, impact reports

The workplace category has the highest number of scenarios (17) and is the most universally applicable.

In-Depth Analysis of Three Recommended Scenarios

Anthropic has highlighted three particularly versatile use cases:

Scenario 1: Generate Your Weekly Work Priorities in One Click

Target Audience: All office workers using calendars and emails.

By authorizing Claude to connect to your Google Calendar and Gmail, it will automatically read your schedule for the week, scan relevant email threads, and identify:

Which meetings need preparation
Which tasks have deadlines
Which emails have not been replied to

Finally, it outputs a prioritized to-do list.

Technical Configuration: Sonnet 4.5 + Extended Thinking + Connectors. No manual sorting needed; open Claude on Monday morning, and within five minutes, know what to focus on for the week.

Scenario 2: Daily Travel Itinerary Auto-Generation

Target Audience: Travelers who dislike planning.

Input your destination, duration, preferences (cultural tour / food exploration / relaxing vacation), and activity limitations (e.g., walking no more than 20,000 steps daily). Claude will:

Search the web for the latest attraction information and operating hours
Compile a detailed daily itinerary
Highlight transportation methods and important notes
Support ongoing dialogue for itinerary adjustments

Technical Configuration: Sonnet 4.5 + Web Search + Extended Thinking.

Scenario 3: One Content Piece, Automatically Adapted for All Platforms

Target Audience: Content creators and marketers.

Provide a long article to Claude, and it can automatically rewrite it into:

Instagram posts (short copy + hashtags)
LinkedIn articles (professional tone + structured formatting)
Email newsletters (summary + call to action)
Twitter/X threads (within 280 characters)

The tone, length, and structure are all automatically adapted for each platform. If paired with the Google Drive Connector, it can directly access your content library to batch rewrite historical articles.

Technical Configuration: Sonnet 4.5 + Extended Thinking + Connectors.

Insights from the 85 Scenarios

1. The Truth About Model Selection

Anthropic’s own scenario design has provided the answer: Sonnet 4.5 is the main model, while Opus appears only in a few scenarios requiring deep reasoning. For most people in most jobs, choosing Sonnet is sufficient. Save your budget for Connectors to allow Claude to connect with your calendar, email, cloud storage, and project management tools, as this will significantly enhance efficiency compared to upgrading models.

2. The Lever for Efficiency Improvement Lies in Connections

Upon examining these 85 scenarios, the true source of transformative change is not the model itself, but Connectors—which enable Claude to read your emails, calendar, document libraries, and Slack messages, then automatically summarize, analyze, and generate outputs.

Model capabilities set the lower limit, while data connections determine the upper limit.

3. Official Guidance on Usage

These 85 scenarios essentially serve as an official user manual. Each scenario is ready to use with a click, eliminating the need to write prompts yourself. If you’re new to Claude or want to explore more applications, browsing this scenario library and using it as needed is more efficient than any tutorial.
