1. Why Claude Excels at Work — The Essentials

It may look similar to ChatGPT, but Claude has several decisive differences:

200K Token Context — Can analyze documents equivalent to 600 A4 pages at once
Artifacts Feature — Edit documents, code, and tables instantly in a separate window
Projects Feature — Upload internal company documents and have conversations that remember context
Lower "Hallucination" Rate — More likely to admit when it doesn't know (advantageous for business document work)

This guide is written based on Claude 3.5 Sonnet / Claude 3.7 Sonnet, and most features can be utilized even on the free plan.

3. Practical Tips to Get 200% Out of Claude

✅ Tip 1: Quality Improves When You Define the Role Clearly

Instead of simply saying "write an email," setting a role like "write as a PR expert with 10 years of experience" makes a noticeable difference in results.

✅ Tip 2: Specify Output Format

Specifying format like "5 bullets," "table format," or "1 A4 page" reduces post-processing time.

✅ Tip 3: Use XML Tags to Separate Inputs

When inserting multiple materials, Claude recognizes XML tags well:

<meeting_minutes>
[Content]
</meeting_minutes>

<request>
Please extract only action items from the above meeting minutes.
</request>

✅ Tip 4: Use Follow-up Edits Like "Shorter," "More Formal"

If the first result isn't satisfactory, don't start over — continue with modification requests like "make the previous result more concise / in a friendlier tone / in English". Since it understands the context, it's much more accurate.

✅ Tip 5: Build a Team Knowledge Base with Projects (Paid)

With Claude Pro or higher, using the Projects feature lets you upload company guidelines, glossaries, and style guides to get context-appropriate results without explaining each time.

⚠️ Common Mistakes

Too Short Requests — Providing context yields much more useful results than "create a marketing plan"
Using Without Fact-Checking — Latest statistics, laws, and specific company information must always be verified
Entering Sensitive Information — Don't input customer personal information or original confidential contracts
