About Cachejay
We built Cachejay because our AI kept waiting on us
AI made it possible to work on more things at once and finish each one faster. It also made the slow part obvious: us. Every chat started with pasting the thread, re-explaining the project and digging up what was agreed. Cachejay is the fix we wanted for ourselves.
Draft the follow-up to this morning’s pricing call.
Happy to. A few questions first:
- Which project is this for?
- What did the client agree to on the call?
- Can you paste the email thread?
- Is anything still open from last time?
Waiting on you
01More, faster
AI gave everyone more projects
With ChatGPT, Claude, Cursor and Codex, one person can run several projects in a day: a feature in one repo, a proposal for a client, a launch plan, three calls. Each one moves faster than it used to. There are simply more of them, and they switch more often.
02The bottleneck
The model waits on the person
The AI can write the draft in seconds. Before that, someone has to tell it what’s going on, and that someone is you: which project, what the client said, what was decided last week, who you owe what. The more AI you use, the more of your day goes to briefing it.
03The fix
A cache for the human
Computers stopped waiting on slow memory by keeping a cache. Cachejay does the same for you: what you saw, said, decided and promised, captured on your Mac as you work and kept current, so any AI app reads it in one go instead of asking. That’s the human cache.
What we believe
A tool that sees your workday has to earn that. These are the rules Cachejay is built on.
No bot in your calls
Calls on Zoom, Meet, Teams and FaceTime are heard on your Mac and transcribed. Nobody gets an invite from a bot, and no audio is kept.
Yours unless you share it
Only you can read your memory. A team sees only the projects each person chooses to share; screen text stays private.
Secrets stay out
Password managers, Keychain Access and private windows are never read, and passwords and keys are masked before anything syncs.
New beats old
A project’s status is rewritten as work comes in, and to-dos tick themselves off with a reason. An out-of-date memory is worse than none.
Any AI app
ChatGPT, Claude, Cursor, Codex, Gemini CLI, Windsurf, VS Code and Zed read the same memory. Switch apps and nothing is lost.
Nothing to wire up
No logins to your email or CRM. Cachejay learns from what passes through your screen, your calls and your agent sessions.
Nothing joins your calls. Your Mac hears them, and they’re transcribed.
About that much memory. It only looks for changes while you’re at the keyboard.
On the Mac, Claude Code, Claude Desktop, Cursor, Codex, Gemini CLI, Windsurf, VS Code and Zed connect directly.
A month after 14 free days, no card. The AI that writes your notes is included. Pricing.
Who makes it
Small and independent
We use Cachejay every day to build Cachejay, so most of what changes comes from hitting the same walls you do.

Questions
Why was Cachejay built?
AI apps made it possible to work on more projects at once and get each one done faster. They still start every conversation knowing nothing, so the person ends up pasting threads, re-explaining projects and remembering what was agreed. Cachejay keeps that context current so the AI can read it instead of waiting on you.
What does “the human is the bottleneck” mean?
The model can draft, code or research in seconds, then waits on you for the context: which project, what the client said, what you already tried. That waiting, multiplied across every chat and every project, is the slow part of working with AI.
What is the human cache?
Everything an AI app would need to know about your work to help without asking: what you saw, what was said on your calls, what you decided and what you owe people, kept up to date. More on the human cache.
Is Cachejay an AI agent?
No. It keeps the context. ChatGPT, Claude, Cursor and Codex do the work with their own tools, and they start already knowing what you know.
Who makes Cachejay?
Cachejay is built independently, by people who use it every day to build it.
