Holdfast is one record that Grok, ChatGPT and Claude all read from. Save your facts, rules and decisions once. Every AI you connect starts with them.

// Sound familiar?

You pay for more than one AI. You're still the cable between them.

Without Holdfast

  • Re-explain the business to every new chat
  • ChatGPT doesn't know what you told Claude
  • Last week's decision is gone
  • Switching AI means starting again

With Holdfast

  • Facts, rules and decisions saved once
  • Every connected AI reads the same record
  • Decisions kept with the reason why
  • Switch AI and your record comes with you
// How it works

Three steps. No terminal.

We set it up together

A short chat, then I set up your trial with you so it works first time.

Connect your AIs

Claude Desktop in one click. ChatGPT and Grok with a link I set up for you.

Save what matters

Facts, rules and decisions go in once. See every memory, who saved it, and undo it.

// What you get

One shared record

Grok, ChatGPT and Claude read the same facts, rules and decisions.

"Not on record"

A check that matches what the AI says against what you saved, so guesses get flagged.

Your data stays yours

The Holdfast file stays on the machine running it. Export it any time.

Full history

Every memory shows who saved it and when. One click to undo.

Team version

Up to 5 people, with shared or private memories.

A person who answers

You deal with me, not a ticket queue.

// Straight answers

What it can't do

Can it force the AI to follow my rules?

No. It reminds each AI of your rules when it connects. It can't make a model obey.

Is anyone using it?

Two testers today. No paying customers yet. I'd rather say that than pretend.

Can I download it myself?

Not yet. I set up every trial with you.

What does it cost?

The 7-day trial is free. Ask me the monthly price when we talk.

Try it free for 7 days.

Tell me which AIs you use and what you keep repeating. I'll tell you honestly if it fits.
