Kep

private ai infrastructure for regulated firms

Private AI for UK regulated industries — law firms and accountants first. Each client gets a dedicated machine in their own office running a local AI model, so there is no cloud path between their documents and anyone outside the firm. We're placing the first machines with a small founding cohort; the online demo lets anyone try it on a fictional law firm.

Local LLMOn-premiseMac StudioUK GDPR
  • One dedicated machine per client — nothing shared between firms
  • Documents never leave the office; works without the internet
  • Full-disk encryption, mandatory
  • Law firms first: matters, deadlines, clause library, conflict checks
  • Fixed fee, not per seat — Pro (Mac Studio) from £399/mo; Standard from £269/mo (in testing)
  • Live demo on a fictional law firm — no sign-up

Project Brain

persistent memory for claude code

Free, open-source Claude Code skill that gives the AI persistent, navigable memory of your projects — their stack, decisions, pitfalls and what's already been done. It reads a small index first and drills into one topic only when needed, so the model stops forgetting, stops mixing projects up, and stops re-reading huge docs into context every session.

Claude CodeSkillMarkdownOpen SourceMIT
  • Small index loaded eagerly — topic detail read on demand
  • Status carries the outcome: verified / failed / in-progress
  • Versioned, not overwritten — the trail of what changed survives
  • One brain catalogs many projects on one server, or a single repo
  • Plain markdown you can read, edit and commit yourself
  • Open-source (MIT) — no sign-up, no payment, no account

Skill Airlock

temporary skills for claude code

Open-source Claude Code skill and CLI that treats agent skills as temporary capabilities, not permanent installations. It finds skills in a local index of sources you choose, audits them in quarantine before they touch your machine, asks you, uses them, and removes them when the task is done.

Claude CodeSkill + CLIPythonOpen SourceMIT
  • Offline search: the query is never stored or sent
  • Static audit of scripts and Markdown, with file:line evidence
  • Verdicts CLEAN / OK / REVIEW / BLOCK, and you decide
  • Modes: once (nothing installed), temp (expires), keep (pinned to a commit)
  • Context budget: token cost and skills unused for 30 days
  • No telemetry, no accounts, no server
