Most AI answers from the internet.

◆ Thremark answers from your life.

• No prompt engineering. Just talk.
• No model picking. The right one kicks in.
• No black box. See and edit what the AI knows.
• No training on your data. API-only, by design.

MARKS

A fact you own. Your diet, routines, preferences, visible in a list, editable anytime. The AI uses your Marks in every chat without you repeating yourself. You always know what it knows.

Set a reminder on any Mark. Thremark notifies you at exactly the right moment.

MEMORY RECALLS

Save a fact once. The AI brings it back in every conversation automatically. When a saved fact goes quiet too long, Thremark reaches out with a notification: "Still relevant?" Most apps wait to be opened. Thremark reaches out first.

FILES

Ask the AI to create a habit tracker, workout plan, trip itinerary, money log, or recipe. Your files live in the conversation: tell it to add a row, fix a section, rename a task, or start from scratch and it updates instantly. No editor to open. Just say it. Nobody else does this.

Long-press any AI reply to save it as a file and keep it forever.

FAST, SMART, AND FULL MODES
