Small tools, each built for one job.

PRIME

Turning Claude into an assistant with a great memory

Claude doesn't remember yesterday, so you spend the start of every session retelling it. PRIME writes down each decision, rule, and correction as it happens, in a plain text file in your own folder, and the next session starts from that record. Works in Cowork and Claude Code.

BylineProof

The writer stays the author.

BylineProof learns your voice from your real writing, asks you for the story instead of making one up, and reviews each draft against 34 known signs of AI writing. Every flag ends with a choice, and keeping what you wrote is one of them.

Claude's memory knows you. PRIME keeps the record.

Keep Claude's memory on. It learns who you are. PRIME writes down each decision, rule, and correction in your project, with the date, so weeks later you can just ask.

YouDo you remember when we talked about delivery for the bakery site? I can't remember what we decided.
ClaudeYes. On October 14 you set the delivery fee at $5, then corrected it to $6 that afternoon. The $6 line is the current one. That same day you also set the order page to pickup only for now, so delivery isn't on the site yet. Want to turn it on?

For companies

AI guardrails and governance

Your people are already using AI tools. Somebody has to decide what company information can go into them, what can't, and who checks the work that comes out.

Diakryon works with leadership teams to write those rules down and get them used. Every engagement is scoped to the company in front of us, so we start with a conversation, not a package.

Questions we help answer
  • Which AI tools are approved here, and for what work?
  • What information never goes into one?
  • Who reviews AI-assisted work before it leaves the building?
  • What happens when someone gets it wrong?
About

Diakryon

Dennis Winten, founder of Diakryon, on the beach at Cannon Beach, Oregon

I run more than a dozen projects through Claude every week, and every morning I was explaining yesterday all over again, from memory, and getting it wrong. So I built PRIME for myself. Now I can ask "what did we decide about that?" and get the answer that actually happened. That turned Claude into an assistant with a great memory.
