Example answers, shortened to fit a 1.14 inch screen.

Answer

The short version.

Direct answers in one or two sentences. No filler, just the answer, spoken back right away.

Best for
Quick facts, definitions, calculations, unit conversions.
Style
Fast, factual, to the point. This is Donna’s default mode.

Example on the pen: you ask “How many ounces in a pound?” and the screen shows “16”

School

Helps you find it yourself.

Donna uses the Socratic method. Instead of handing over the answer, she asks guiding questions that take you through the problem step by step.

Best for
Homework help, test prep, concept mastery, critical thinking.
Style
Questioning, encouraging, step by step.

Example on the pen: you ask “What is 15% of 80?” and the screen shows “What is 10% of 80? Start there.”

Research

The long version.

Detailed, well-structured responses with depth and nuance, for when a quick answer is not enough: full explanations, comparisons and analysis.

Best for
Research papers, deep dives, comparisons, complex subjects.
Style
Thorough, structured, analytical.

Example on the pen: you ask “Causes of World War I?” and the screen shows “Militarism, Alliances, Imperialism, Nationalism”

Creative

Ideas you did not ask for.

A brainstorming partner that makes unexpected connections and offers new angles on whatever you are working on.

Best for
Writing prompts, brainstorming, storytelling, thinking differently.
Style
Imaginative, playful, surprising.

Example on the pen: you ask “Give me a story idea.” and the screen shows “A lighthouse keeper who is afraid of the dark.”

Language

Practice out loud.

A language tutor you can talk to. Donna answers in your target language, with translations and pronunciation tips. Spanish now, more languages coming.

Best for
Language learning, translation practice, vocabulary, conversation.
Style
Bilingual, educational, encouraging.

Example on the pen: you ask “Spanish for library?” and the screen shows “biblioteca”

Founders

110 pens. That is the whole first run.

Every product starts with a first batch. Ours is 110 pens. They are built before our production molds exist, so we assemble and test every one by hand in Illinois. We stopped at 110 because that is how many we can build ourselves and still check personally before it ships.

Why it exists. The money from this run helps pay for the production molds that every later pen will be made with. Your order is part of why there will be more of them.

What it means. Founders are the first people to believe in it. Your feedback goes straight to the people who built your pen, and it shapes every version after.

Logan Holby, founder. Mundelein, Illinois.

How does Donna answer?

Hold the AI button and ask your question out loud. Donna works out the answer, says it through the pen’s speaker and shows it on the color screen.

Does it still write when the battery is empty?

Yes. The ink is an erasable cartridge in a real ballpoint, so the pen writes with or without power.

How does it connect?

The pen connects wirelessly to the Nexus Pen app. There are no pairing codes.
