Brand system by Plumage for the founder's Lokii. The logo and the website are the founder's design. Part of [Our work](https://plumage.studio/work) by [Plumage](https://plumage.studio).

Tagline: "Learn anything. Remember everything."

## Introduction

Lokii is an AI retention system for studying, in private beta. You upload notes, textbooks, PDFs or lectures; it maps the material as a knowledge graph, predicts what is fading per concept, routes each item to a technique (memory palace, spaced recall, teach-back) and schedules reviews before the predicted dip. It is built first for medical students, exam-heavy university programmes, bar, CFA and CPA candidates, and professionals in fast-moving fields.

The fox, the wordmark and the website are the founder’s. The logo is redrawn clean in flat colour, not redesigned, and the colour, type and voice are taken from lokii.ai first, so the logo and the site are one brand.

Lokii should feel like the smartest friend in the library: a warm, slightly mischievous fox standing in front of real memory science. Every surface pairs one playful fox moment with one calm, exact fact, so students facing exams they can’t afford to fail trust it.

## Marks

The fox comes first and the word follows it, in the founder’s proportions. Use the lockup wherever there is room for both; the wordmark alone where the fox is already on screen; the fox alone for the app icon, the profile picture and stickers. The two ear-dots over the i’s are the wordmark’s own detail: never swap them for plain round dots, and never redraw, respace or reorder the lockup.

## Colour

- **Paper** #FFFFFF: Main ground of the site and the app; the fox’s white muzzle.
- **Mist** #F3EEFF: Soft lilac ground for sections, cards and the memory palace floor (already on lokii.ai).
- **Ink** #0F0D1A: Wordmark letters, headlines and body text (lokii.ai’s text colour).
- **Slate** #6B7280: Body text on lokii.ai (Inter 18 px).
- **Lokii Purple** #A855F7: The fox’s fur and the brand colour: the second headline line, buttons, the path through a palace.
- **Lavender** #CDA6F7: The fox’s inner ears: tints, charts, illustration light.
- **Den** #4A1590: The fox’s outline: small text on lilac, icons, dark mode ground.
- **Ember** #FF7A2F: A fox’s real colour, used once per screen at most: a streak, a due review, a sticker.

## Type

## Voice

Lokii speaks as lokii.ai already does: a sharp study partner who has read the research. Warm, exact, never cramming.

The site names its science plainly, from Ebbinghaus in 1885 to Murre and Dros in 2015, and keeps its sentences short. Every surface pairs one playful fox moment with one calm, exact fact.
