Context Is the New Competitive Advantage

Never start from empty.

Your context, ready before the first word.

The problem

They don't
know you yet.

Every session starts cold. You re-explain. They forget. One URL ends that.

Every time you switch tools, you start as a stranger. CacheTank ends that.

World's First

Five things nobody else can say.

We checked. Thoroughly.

The only AI context product that uses zero AI.

What you saved is what gets served. No middleman. No mystery.

Works with every AI on earth. No plugin. No permission.

If it can read, it knows you. That's literally it.

The only context that gets smarter the more you use it.

Notes become patterns. Patterns become principles. Automatically.

Nothing to install. Nothing to configure. Nothing to break.

Your grandma could set this up. Respectfully.

When the next AI tool launches, you're already there.

Platform-neutral by design. Not by partnerships we haven't signed yet.

Where it works

Use it everywhere.

Claude remembers you — inside Claude. ChatGPT remembers you — inside ChatGPT. Switch tools? Stranger again. CacheTank is the one layer that follows you everywhere.

New tool every week. Context travels with you.

Any MCP-compatible tool

If it speaks MCP, it speaks CacheTank.

Their memory is theirs. Yours is yours. One URL — no starting over when you switch.

Tested with Gemini, Perplexity, ChatGPT Plus, Grok, and Claude (via MCP). ChatGPT Free users: use Copy Context from your URL page — works perfectly.

How it works

Three steps. That's it.

Save

Say "Cache it" in Claude, or click the extension. Filed instantly.

Your URL

One link. Always current. Always yours.

Connected

Every AI already knows your situation.

Your personal context URL

cachetank.com/ctx/you

Your info. Your style. Yours forever.

Get your URL

How it's organized

Your files.
Structured.

Not AI. An organized file system. Save once — works everywhere.

Filed, not dumped.

Clean categories — who you are, what you're building, how you work. Right info, right place.

Organized by default

Preferences that actually stick.

Your style, tools, constraints — saved once, available in every session.

Save once, use everywhere

Your files. No black box.

No algorithm. What you save is what gets served. Predictable. Yours.

Transparent by design

"Cache it" — two words. Done.

Say it in Claude or click the extension. Filed automatically. No folder picking.

Instant, organized saves

Your knowledge. Your edge.

Own what
you know.

The tools will eventually fix their own memory. ChatGPT memory stays in ChatGPT. Claude's context stays in Claude. The moment you switch — and you do switch — you start from zero.

CacheTank is the one layer that crosses all of them. Not locked to any platform. Not lost when the next tool launches. Yours, permanently.

Your knowledge compounds

Every save makes the next session smarter.

One URL. Every tool.

Your info travels with you. No re-explaining, ever.

No walls between tools
