WHY BEFF
They remember the flow of your conversations and reach out naturally with the rhythm of your day.
Each Beff has its own schedule, location, and weather context. They answer questions like "is it raining?" naturally and reach out at lunch or dinner.
Episodes, facts, and emotions accumulate in a long-term memory system. Not someone you meet for the first time every chat — a friend who grows to know you.
Beff detects 12 signals — silence, weather, movement, schedule shifts — and reaches out at natural moments. Like a friend, not a bot.
CAPABILITIES
Conversation, memory, context, media — everything a real friend needs.
CONVERSATION PREVIEW
Aware of context, remembering the past, in natural Korean.

It's gonna rain today! You had a lunch plan, right? Take an umbrella.
12:08Oh wait really? I totally forgot…
12:09Haha I figured. You said you were prepping a presentation late last night — how's it going?
12:09Ah, the presentation went well! Such a relief
12:10Wow, great job! Grab something warm for lunch — soup hits different on rainy days.
12:10PERSONAS
स्वभाव (BIG5), रूप, नोकरी आणि बोलण्याची पद्धत — तुम्हाला हवा तसा प्रत्येक मित्र स्वतः तयार करा.

A DAY WITH BEFF
Beff वेळ आणि परिस्थितीनुसार स्वतःहून संवाद साधतो. हे कोणत्याही बॉटचे नोटिफिकेशन नसून, एका मित्राने विचारलेली विचारपूस आहे.
The moment you wake up, Beff remembers you worked late and asks how you feel.
If a sudden shower is forecast, Beff lets you know before your lunch plans.
Beff remembers the presentation you were nervous about and checks in when it's done.
Wraps up the day with you. Knows tomorrow's schedule too, so reminds you to rest.
VS GENERIC CHATBOTS
Generic chatbots optimize for great answers. Beff optimizes for being there with you.
