    Claude AI · Fitted Claude

    Claude’s privacy practices are more nuanced than most users realize — and Anthropic buries the details across multiple support pages. This guide consolidates everything you need to know: what data is collected, how long it’s kept, who can see it, and what you can do to protect your privacy.

    What Data Claude Collects

    When you use Claude.ai, Anthropic collects:

    • Conversation content: Your messages and Claude’s responses
    • Uploaded files: Documents, images, and PDFs you share in conversations
    • Account information: Email, name, and payment information (for paid plans)
    • Usage data: How you interact with the interface, features used, session timing

    How Long Anthropic Keeps Your Data

    By default, Anthropic retains conversation data for up to five years from the date of the conversation. You can delete individual conversations or request full account deletion through the Claude.ai interface, which will remove your data from Anthropic’s systems on an expedited basis.

    Is Claude Used to Train Future Models?

    This is the question most users want answered clearly. Here’s the breakdown:

    Consumer Accounts (Claude.ai free and paid plans)

    By default, Anthropic may use conversations from consumer accounts to improve its models. You can opt out of this. Go to Settings → Privacy → Data Usage in Claude.ai and toggle off “Allow my conversations to be used for training.”

    Business and API Accounts

    Anthropic does not use API or enterprise customer data for model training by default. Business customers can also access zero-data-retention (ZDR) options, where conversation data is not logged or stored beyond the immediate session.

    Who Can Access Your Conversations?

    • Anthropic employees: Can access conversations for safety review, legal compliance, or quality improvement purposes — governed by internal access controls
    • Third parties: Anthropic does not sell conversation data to advertisers or third parties
    • Law enforcement: Anthropic will comply with valid legal requests (subpoenas, court orders) as required by US law

    Privacy Best Practices

    • Opt out of training data use in Settings if you use the consumer interface for sensitive work
    • Use API or enterprise accounts for work involving confidential client information
    • Don’t paste genuinely sensitive data (SSNs, financial account numbers) into any AI interface
    • Delete conversations containing sensitive information after use
    • Consider Claude for Teams or Enterprise for business use cases requiring formal DPA agreements

    Frequently Asked Questions

    Does Claude sell my data?

    No. Anthropic does not sell conversation data to advertisers or third parties.

    Can I opt out of Claude training on my conversations?

    Yes. Go to Settings → Privacy → Data Usage in Claude.ai and toggle off “Allow my conversations to be used for training.”

    Is Claude HIPAA compliant?

    Anthropic offers HIPAA-eligible configurations for enterprise customers. Standard consumer Claude.ai accounts are not HIPAA compliant. Contact Anthropic’s enterprise team for healthcare-specific compliance arrangements.

  • Claude Context Window Explained: From 200K to 1M Tokens

    Claude Context Window Explained: From 200K to 1M Tokens

    Last refreshed: May 15, 2026

    Model Accuracy Note — Updated May 2026

    Current flagship: Claude Opus 4.7 (claude-opus-4-7). Current models: Opus 4.7 · Sonnet 4.6 · Haiku 4.5. Claude Opus 4.7 (claude-opus-4-7) is the current flagship as of April 16, 2026. Where this article references Opus 4.6 or earlier models, those references are historical. See current model tracker →. See current model tracker →

    Claude AI · Fitted Claude
    Updated April 2026: Claude Sonnet 4.6 and Opus 4.6 now support a 1 million token context window at standard pricing. Haiku 4.5 supports 200,000 tokens. The information below has been updated to reflect current specs.

    Claude’s context window is one of its most practically important technical specifications — and one of the least well understood. This guide explains tokens and context windows, how Claude’s compare to competitors, and strategies for working effectively within context limits.

    What Is a Context Window?

    A context window is the total amount of text a model can process in a single session — everything it can “see” and reason about at once. Context is measured in tokens. As a practical rule: 1,000 tokens ≈ 750 words.

    Claude’s Context Windows

    Access Method Context Window Approx. Words
    Standard Claude (all plans) 1,000,000 tokens (Sonnet/Opus), 200,000 (Haiku) ~750,000 words (Sonnet/Opus)
    Enterprise Claude 500,000 tokens ~375,000 words
    Claude Code 1,000,000 tokens ~750,000 words

    What Fits in 200K Tokens?

    • A full-length novel (~100,000 words)
    • 100-200 typical business emails
    • 10-15 long research papers
    • An entire small codebase (5,000-10,000 lines)
    • A year’s worth of meeting notes from a small team

    PDF and Document Token Costs

    • PDFs: 1,500-3,000 tokens per page
    • Plain text: ~1 token per 4 characters
    • Images: 1,000-4,000 tokens per image
    • Code files: 500-2,000 tokens per file

    Strategies for Long Contexts

    • Extract before uploading: Only upload relevant PDF sections, not full documents
    • Use Projects for reference material: Store knowledge base docs in Projects rather than re-uploading every session
    • Auto compaction (Claude Code beta): When coding sessions approach limits, Claude automatically summarizes history to continue

    Frequently Asked Questions

    How many pages can Claude read at once?

    With 200K tokens and ~1,500-3,000 tokens per PDF page, roughly 65-130 pages while leaving room for conversation.

    Does Claude forget things in long conversations?

    Not within the context window. In very long conversations approaching the limit, older content may be truncated.

  • Claude vs Perplexity: Research Engine vs Reasoning Partner

    Claude vs Perplexity: Research Engine vs Reasoning Partner

    Last refreshed: May 15, 2026

    Claude AI · Fitted Claude

    Comparing Claude to Perplexity is a category error — they’re not trying to do the same thing. Perplexity is a real-time research engine. Claude is a reasoning partner. Understanding the distinction helps you build the most effective research workflow.

    What Perplexity Does Best

    • Real-time information: Searches the live web, summarizes current events with source links
    • Source citation: Every claim has source links for verification
    • Quick research: Fast sourced answers for “what is X” and “what happened with Y”
    • Academic research: Academic mode searches peer-reviewed papers

    What Claude Does Best

    • Deep reasoning: Complex multi-step analysis and strategic thinking
    • Document synthesis: Upload a 200-page report and ask for analysis — Perplexity cannot do this
    • Writing quality: Significantly stronger long-form writing
    • Code: One of the best coding models. Perplexity is not a coding tool.
    • Private documents: Works with confidential content you upload

    The Hybrid Workflow (Best of Both)

    1. Perplexity first: Rapid research, current information, source discovery
    2. Claude second: Synthesis, analysis, writing. Take what Perplexity found and reason through the implications

    At $20/month each, running both costs $40/month — worth it for professionals who research and write regularly.

    Frequently Asked Questions

    Should I use Claude or Perplexity for research?

    Use Perplexity for finding current information with sources. Use Claude for analyzing, synthesizing, and writing. Ideally, use both — Perplexity first, Claude second.

    Does Claude have real-time web access?

    Not by default. Claude has a knowledge cutoff and doesn’t browse the web in real time unless connected via MCP or specific integrations.

    Claude AI · Fitted Claude

    DeepSeek emerged as the most disruptive AI development since GPT-4 — a Chinese lab producing frontier-quality models at dramatically lower cost. In 2026, it’s a genuine competitor to Claude in several categories. But the comparison isn’t only about performance. Privacy and data sovereignty matter. This guide covers all three dimensions.

    Performance Comparison

    Benchmark Claude Opus 4.6 DeepSeek
    SWE-bench (coding) 80.8% ~49% (V3), higher for R1
    GPQA Diamond 91.3% Competitive
    Math reasoning Top tier R1 leads on pure math
    Context window 200K tokens 128K tokens

    Claude leads on real-world software engineering and long-document reasoning. DeepSeek R1 is competitive or superior on pure math. For most professional use cases, Claude holds the performance edge.

    Pricing Comparison

    DeepSeek’s API pricing is 10-20x cheaper than Claude’s — roughly $0.27-0.55 per million input tokens vs Claude’s $3-15. For high-volume API applications where cost is the primary constraint, DeepSeek is a serious consideration. The consumer interface is free vs Claude’s $20-200/month paid tiers.

    The Privacy Question

    DeepSeek is a Chinese company. Its data handling is subject to Chinese law, which includes requirements to provide user data to Chinese government authorities under certain circumstances. Multiple national governments have restricted DeepSeek on government systems. For professionals handling confidential client data or sensitive business information, the data sovereignty difference between Anthropic (US-incorporated) and DeepSeek (Chinese-incorporated) is material.

    Choose Claude If You…

    • Handle confidential professional, legal, or medical data
    • Need highest performance on software engineering tasks
    • Require long-document analysis (200K vs 128K context)
    • Need US-based data handling

    Frequently Asked Questions

    Is DeepSeek as good as Claude?

    Competitive on math and logic. Claude leads on SWE-bench software engineering, long documents, and writing quality.

    Is DeepSeek safe to use?

    For general consumer use, immediate risk is low. Professionals handling sensitive data should consider DeepSeek’s Chinese data jurisdiction carefully.

  • Claude Extended Thinking: When and How to Use It

    Claude Extended Thinking: When and How to Use It

    Last refreshed: May 15, 2026

    Claude AI · Fitted Claude

    Extended thinking is Claude’s most powerful reasoning mode — and the one most people never use correctly. This guide explains what extended thinking does, when it genuinely improves outputs, how to enable it, and when you’re better off with a standard prompt.

    What Is Extended Thinking?

    Extended thinking gives Claude a dedicated reasoning phase before generating its final response. Claude works through a problem on “scratch paper” before writing its answer — exploring multiple approaches, identifying errors in its own reasoning, and building a more deliberate chain of thought. In Claude 4.6 models, this is called adaptive extended thinking — Claude dynamically adjusts how much thinking it does based on problem complexity.

    When Extended Thinking Genuinely Helps

    • Complex math and logic problems requiring step-by-step reasoning
    • Multi-step coding tasks with many interdependent components
    • Strategic analysis requiring weighing many variables
    • Difficult research synthesis where accuracy matters most
    • Any task where “think step by step” would help — extended thinking does this automatically

    When Extended Thinking Is Overkill

    • Simple factual questions with clear answers
    • Routine writing tasks (emails, summaries, short copy)
    • Format conversion or data transformation
    • Tasks where speed matters more than depth

    How to Enable Extended Thinking

    In Claude.ai: Look for the thinking toggle before sending your message. Available on Max tiers and higher.

    Via API: Pass "thinking": {"type": "enabled", "budget_tokens": 10000} in your request. Higher budget_tokens allows more thorough reasoning but increases latency and cost.

    What You See During Extended Thinking

    Claude shows a collapsed “thinking” section before its response. Expand it to see the reasoning chain — useful for verifying logic or understanding how Claude approached a problem. The thinking section is exploratory and may contain dead ends; this is normal.

    Frequently Asked Questions

    Does extended thinking always give better answers?

    No. It improves accuracy on complex reasoning tasks but adds latency. For simple tasks, standard mode is faster and just as accurate.

  • Claude Memory: How It Works and How to Configure It

    Claude Memory: How It Works and How to Configure It

    Last refreshed: May 15, 2026

    Claude AI · Fitted Claude

    Claude’s memory feature changes the product from a stateless chatbot into something that actually knows you. Without memory, Claude starts from zero every conversation. With memory configured, Claude builds a growing knowledge base about you that it draws on automatically. This guide explains how it works and how to get the most from it.

    How Claude Memory Works

    Claude’s memory is an auto-synthesized knowledge base. Approximately every 24 hours, the system reviews recent conversations and extracts facts, preferences, and patterns worth remembering — then stores those as structured memory entries. Memory is separate for Projects vs. standalone conversations — each Project has its own memory space.

    What Claude Can Remember

    • Your name, role, and professional context
    • Preferred communication style and tone
    • Ongoing projects and their context
    • Tools, frameworks, and workflows you use
    • Output format preferences
    • Things you’ve asked Claude not to do

    How to Configure Memory

    In Claude.ai, go to Settings → Memory. You’ll see auto-generated memory entries. You can review, edit, delete, or manually add memories. You can also instruct Claude directly: “Remember that I prefer bullet points” or “Don’t forget my target audience is non-technical executives.”

    Memory vs. Project Instructions

    Project instructions are static — written once, apply to every conversation. Memory is dynamic — evolves as Claude learns. Use Project instructions for consistent role context. Use memory for personal preferences and evolving project context.

    CLAUDE.md for Claude Code

    For Claude Code, place a CLAUDE.md file in your project root. Claude Code reads it at the start of every coding session. Use it for: project architecture, coding standards, common patterns, known issues. This is the most powerful memory tool for developers.

    Frequently Asked Questions

    Does Claude remember everything I say?

    No. Memory synthesizes and stores key facts and preferences, not verbatim conversation logs. It’s selective — designed to capture what’s useful.

    Can I delete Claude’s memories about me?

    Yes. Go to Settings → Memory in Claude.ai to view and delete any memory entries.

  • Can Claude AI Generate Images? Complete Capabilities Guide

    Can Claude AI Generate Images? Complete Capabilities Guide

    Last refreshed: May 15, 2026

    Claude AI · Fitted Claude

    The most common question new Claude users ask: can Claude generate images? The direct answer is no — Claude cannot create images from text prompts. But Claude’s actual image-related capabilities are extensive and genuinely useful. This guide covers everything Claude can and cannot do with images.

    What Claude Cannot Do: Image Generation

    Claude is a text-based AI model. It cannot generate, create, or render images of any kind. Use these tools instead: Midjourney (best quality artistic/photorealistic), DALL-E 3 (via ChatGPT), Adobe Firefly (strong for commercial use), Stable Diffusion (open-source, runs locally), or Imagen (via Gemini).

    What Claude CAN Do With Images

    Image Analysis and Description

    Upload any image and Claude analyzes it in detail — describing content, identifying objects, reading text, interpreting charts, and answering specific questions about visual content.

    Text Extraction from Images

    Upload a photo of a document, whiteboard, or screen and Claude extracts and transcribes the text — including handwriting, unusual fonts, and partial visibility.

    Chart and Data Interpretation

    Upload a chart or visualization and Claude interprets the data, identifies trends, extracts specific values, and explains what the visualization shows.

    SVG Generation

    Claude generates SVG graphics — scalable vector graphics written as code that render as visual output. Useful for diagrams, icons, and simple visualizations. This is code-based, not AI image generation.

    Image Generation Prompts

    Claude writes excellent prompts for image generation tools. Describe what you want and ask for “a detailed Midjourney prompt” — Claude understands the syntax and conventions of major image tools.

    Frequently Asked Questions

    Can Claude make images?

    No. Claude cannot generate images. Use Midjourney, DALL-E, Adobe Firefly, or Stable Diffusion.

    Can Claude read or analyze images I upload?

    Yes. Claude analyzes photos, screenshots, documents, and charts on all Claude plans.
