Universal AI logbook

Record anything. Ask it later.

Engrayn turns lab notes, project updates, maintenance fixes, customer calls, and everyday observations into a searchable memory organized by topic.

Why it matters

Forgotten context quietly turns into repeated work.

Engrayn is built around the small details that usually disappear: the reason a decision changed, the last fix that worked, the personal note you meant to remember, or the customer context someone has to reconstruct later.

500+

If a 10-person team forgets just one useful decision each week, that becomes more than 500 loose ends to rediscover every year.

15 min

A quarter hour spent rebuilding context does not feel expensive once. Repeated across projects, calls, chores, and handoffs, it becomes a hidden tax.

1 place

Work notes and personal observations do not need separate memory systems. The topic is different, but the capture habit is the same.

How it works

One capture pattern for every kind of work.

The landing page stays simple. The signed-in app is where users save entries, filter timelines, and ask questions against their own Supabase-backed data.

Choose a topic

Pick Lab, Project, Maintenance, Customer, Personal, or Other, then name the exact thread you are tracking.

Save the entry

Write what happened. Engrayn summarizes the note, extracts useful tags, and stores it with your account.

Ask later

Search your saved history with simple questions like "show maintenance notes" or "what changed on the rebrand?"

Subscriptions

Pricing based on the memory you want to keep.

Plans are organized around active topics and API access, so Engrayn can be both a personal logbook and a memory layer for agents, scripts, and AI apps.
