Lineu — Turn Questions into Sparks

Lineu is an AI companion for continuous thinking and learning. It captures meaningful moments from your AI conversations and turns them into Sparks — ideas, insights, and directions worth revisiting.

Instead of letting valuable thoughts disappear after each chat, Lineu helps you keep them, organize them, and explore them further — directly inside your AI-powered workflow.

✨ What is a Spark?

A Spark is a captured moment of thinking.

It can be:

A key insight
A piece of knowledge
An emerging idea
A direction worth exploring further

Sparks are created directly from your AI chats and stored as structured, actionable cards.

🚀 Features

🔹 Capture Sparks from chat

Create Sparks directly from your AI conversations using a simple command.

No context switching. No manual note-taking. Your thinking stays uninterrupted.

🔹 Two visual modes

Switch between two visual modes depending on how you think:

Focus mode — stay in the flow while exploring
Review mode — step back and reflect on your Sparks

🔹 Save, tag, and organize

Save Sparks that matter to you.

Add tags to categorize and filter Sparks, making it easy to revisit ideas later and build your personal knowledge map.

🔹 Dive deeper

Some Sparks deserve more attention.

Select any Spark to dive deeper — explore more detailed explanations, related ideas, and new directions, powered by AI.

A question doesn't have to end with an answer.

🧠 How it works

🌱 Philosophy

Lineu is not a productivity tool.

It's a thinking companion.

We believe the most valuable part of an AI conversation isn't just the answer — it's the moment where understanding begins.

Lineu exists to preserve those moments.
