A memory that never resets

brainbox is persistent, portable memory for your AI tools. One private graph of what you know — read and written by Claude, Cursor, ChatGPT and your own scripts. Independently benchmarked, portable across vendors, and yours to export.

Live, and in use.

Two products live in production — one with a paying client — and a flagship in early access. Everything we claim is measured, not asserted — the quality numbers come from independent benchmarks you can read.

Portable AI Memory
brainbox

A memory that never resets. One private graph of what you know — read and written by every AI tool you use, from Claude to Cursor to ChatGPT to your own scripts. Portable across vendors, and yours to export.

Sign Language Interpreter
Ishara

Real-time Kenya Sign Language to text and speech, running entirely in the browser — no app, no server, no internet required. Built for the 300,000 Deaf Kenyans other tools forgot.

Research-first. Product-second.

We don't build tools and then look for problems. We study systems, find the structural gaps, and build only what closes them.

01
Observe independently

Every system tells you two stories — what it reports and what's actually happening. We build tools that listen to both.

02
Measure the gap

The distance between what you expect and what you see isn't error. It's information. Our products are built to surface that gap and make it actionable.

03
Ship what works

Offline-first. Self-hostable. Designed for the places where reliable infrastructure doesn't exist yet — because that's where the work matters most.

The research behind the product

brainbox's memory claims come from the same convergence method we publish on — independent measurement, stated honestly. Our first paper, Measured Forgetting, is out, with an open benchmark and statistically significant results.

Measured Forgetting — published

The forgetting research behind brainbox, turned on context management for local LLMs. V2 beats V1 on all 7 models tested (sign test p = 0.008) — with an open-source benchmark and algorithm. Read the paper →
