Why this matters
Default Claude is mid Claude
Open the Claude desktop app for the first time and you get a chat box. That's it. No memory, no context, no idea who you are, no knowledge of your tools. Every conversation starts from zero. So every conversation feels like talking to a brilliant stranger.
The 5 settings below are how you stop doing that. 20 minutes to flip them all on. After that every response is faster, more personal, and shaped around your actual life.
These work on the Claude desktop app (Mac, Windows) and on Claude.ai in the browser. Some require a Pro or Max plan to unlock fully.
Move 1
Fill in the personal context box
Settings → Profile → Personal Preferences. There's a text box. It's empty. Almost nobody fills it in. The people who do get responses that feel custom-built every time, because Claude loads that text into every conversation.
Treat it like introducing yourself to a brilliant new assistant on day one. Tell them what you do, what you're working on, how you like to communicate, and the things they need to know to be useful. Edit the bracketed parts below and paste it in.
Personal context template
About me: [Your name]. [Your role / job title]. [City or timezone if you talk about scheduling a lot.] What I do day-to-day: [1-3 sentences on the actual work. What you build, who you serve, what success looks like.] What I'm working toward: [Your top 2-3 goals or projects right now. Be specific. "Grow my newsletter to 10k" beats "grow my audience."] How I communicate: [Casual or formal. Brief or detailed. I like step-by-step or big-picture. Direct feedback or softer framing.] How I want you to respond by default: [Length preference. Whether to ask clarifying questions before long answers. Tone. Format defaults like bullets vs prose. What NOT to do (e.g. "no preamble, no em-dashes, no 'let me know if you want anything else'").] Tools I use a lot: [Whatever comes up often. Notion, Linear, Figma, your stack, your workflow tools.] Things to remember about me: [Anything that would change your answer if you knew it. Allergies if you ask cooking questions. Family context if life-planning comes up. Specific values or hard rules.]
Pro move: if you don't know what to put, ask Claude to interview you. "Interview me with 7 questions to fill out my personal context box. Ask one at a time." Then paste the output into the box. 5 minutes, done.

Turn on memory
Settings → Features → Memory. Flip the toggle.
Without memory, every conversation is a clean slate. You repeat yourself constantly. With memory on, Claude builds a running understanding of who you are across sessions. The project you mentioned last Tuesday is still there on Friday. The way you explained your business in May is still loaded in November.
You can see what Claude remembers (and edit or delete entries) at any time in the Memory settings. So you stay in control, you just stop having to re-explain yourself every session.
If you don't see the memory toggle, you're likely on the free plan. Pro and Max unlock it. The Pro upgrade pays for itself the first week you stop re-explaining context.
Worth knowing: memory works best when you occasionally tell Claude "remember that I..." for things worth keeping. The auto-extraction is good. The manual hint is better.

Create a custom writing style
Claude has 3 built-in writing styles (Normal, Concise, Explanatory). They're fine. They're also generic. The real unlock is custom styles, which you can build from samples of your own writing.
To create one in the desktop app: click the style picker in any chat → Create custom style → paste 1-3 samples of your writing → Claude generates a style instructions block.
But you can do this better by running the prompt below first in a fresh chat. It extracts your patterns more precisely than the built-in flow, and you can paste the output straight into the custom style box.
Style extraction prompt
I'm pasting 3 samples of my writing below. I want you to extract the patterns and write me a "custom style" instructions block I can paste into Claude's Custom Style settings so every response sounds like I wrote it.
Look for:
- Sentence length and rhythm
- Vocabulary level and any specific words I lean on
- How I use punctuation (em-dashes, parentheticals, lists)
- Tone (formal, casual, direct, warm)
- Structure (do I open with a hook, bury the lede, use headers)
- Anything I never do (specific words, phrases, patterns I avoid)
Output a single instructions block under 200 words, written as direct rules to follow ("Use short sentences. Lead with the result. Avoid words like X, Y, Z.").
Here are my samples:
---
[Paste sample 1]
---
[Paste sample 2]
---
[Paste sample 3]
--- Tip: use samples that represent the kind of writing you want Claude to produce, not random emails. If you want Claude to write LinkedIn posts in your voice, paste your 3 best LinkedIn posts. Garbage in, garbage out.

Set up projects for everything you do regularly
Projects are dedicated workspaces inside Claude. Each one has its own context (a system prompt you write once), its own file uploads, and its own memory thread. You stop having to re-explain context for the same recurring task.
The mistake most people make is creating one or two projects and never using them. The fix is to seed 5 starter projects on day one, even if some are skeletal. The friction of creating a new project later is what kills the habit.
Here are the 5 to create right now. For each one, write a short system prompt describing your role, your goals, and what you want Claude to do by default.
Work
Your job description, current quarter goals, team structure, the 3-5 people you collaborate with most, your manager's priorities, the products or accounts you own.
Content
Your brand voice doc, your niche, your top 5 performing pieces, your content pillars, who your audience is, the platforms you publish on.
Money
Your income sources, your monthly burn, your savings rate, your financial goals, the apps you use (Mercury, YNAB, whatever), your tax situation at a high level.
Personal Growth
The skill you're trying to build right now, the books you're reading, the people whose work you study, your weekly habits.
Side Projects
What you're building, who it's for, the current blocker, the tech or tools involved, your launch timeline.
Pro move: upload 2-3 reference documents into each project. For Work, drop in your job description and last quarter's plan. For Content, your brand voice doc and top-performing pieces. Claude treats uploaded files as always-available context inside that project.
Move 5
Connect your tools
Settings → Connectors. This is where Claude stops being a chat box and starts being an assistant that can actually do things in your accounts.
Don't connect everything. Start with these 4. They cover 90% of daily use and they're the safest to leave on always-allow.
Google Drive
Claude can read any doc, sheet, or slide you point it at. Killer for "summarize this 40-page PDF" or "look at last quarter's deck and tell me what to update."
Gmail
Triage your inbox, draft replies in your voice, search across threads. Pair with the writing style step and replies sound like you.
Google Calendar
Schedule context. Claude can see your week and answer "when am I free for an hour next Tuesday" without you copy-pasting your calendar in.
Notion (or your notes app)
Your second brain becomes Claude's second brain. Project docs, meeting notes, reference material, all queryable in chat.
About "always allow": when Claude asks for permission to read a file or send an email, you can approve once or always. Always-allow saves you 20 clicks a day. The tradeoff is Claude can act on those connectors without re-asking. For read-only stuff (Drive, Calendar) this is fine. For write actions (sending emails, deleting files) think twice and keep the per-request prompt on.
After the basics: the next connectors worth adding are Notion (or your notes app), Linear (if you ship product), and Slack (if you live there). Skip the rest until you have a specific use case.
