Start a conversation — Claude already knows you

Open any conversation. Claude pulls your context automatically — role, constraints, active projects. Already there.

First time? Tell Claude about yourself during the conversation, then say "Cache it" — your info is saved for every session from then on.
The magic shortcut
Two words.
Everything saved.

Say "Cache it" in any Claude conversation. It's saved. Next session, Claude already knows.

A typical session with Claude
Say it. It sticks.
The conversation ends. The context doesn't. Every decision, constraint, and preference you tell Claude can be saved in two words.
You
I'm working on a B2B SaaS onboarding flow. We're using React + Supabase. The design system is our own, not shadcn. Keep suggestions within those constraints.
Claude
Got it — React + Supabase, custom design system. No shadcn suggestions. Let's look at your onboarding flow...
You
Cache it
Claude
✓ Saved to CacheTank — React + Supabase stack, custom design system constraint, B2B SaaS onboarding project. Claude will remember this next session.

Works mid-conversation

Say "Cache it" any time — not just at the end. Saves the relevant context right then.

Instant next session

Everything saved is already loaded in your next conversation. Claude walks in knowing.

Same two words, anywhere

Claude Desktop, Claude.ai, any MCP tool. One shortcut everywhere.

Files, not magic

Structured files you can review any time. You know exactly what Claude sees.

What changes
Claude stops asking.
Starts knowing.

Every session — Claude already knows.

Code review

Stack, patterns, lint rules — already loaded. No setup questions.

"Looks clean — keeping it in your existing pattern with the custom design system."

Writing & content

Voice, tone, what's published — every draft calibrated to how you write.

"Keeping the contrarian tone you prefer — softened the opening per your style notes."

Strategy & planning

Active projects, constraints, prior decisions — skips the briefing entirely.

"Given the March deadline and your team of two, here's what's realistic..."

Research & analysis

No recapping. Claude knows what you already know and builds from there.

"You've already ruled out X — building on the remaining options from your notes..."

Team context

Shared team URL carries brand, decisions, initiatives. Every teammate's Claude already knows the company.

"Matching your brand tone from the team context — here's the draft..."

Switching tools mid-task

Researched in Perplexity, now in Claude? CacheTank bridges the gap. Claude picks up where you left off.

"Based on the research context in your CacheTank, here's the next step..."
Not just at the start

Ask Claude to check
your CacheTank
mid-conversation.

Ask Claude to pull anything from your CacheTank at any point — not just at session start.

Brand voice mid-draft

Found it. You prefer: direct over formal, no jargon, short sentences, contrarian framing where it fits. Applying that now — here's the draft:
You
Nice. Cache it — add "no em dashes" to the style rules
