18:42
Cabbage, ground meat, eggs.

Easy, honestly.

WHAT IS SIDEFOGLE

AI isn't just a work tool.

For your life, your downtime, your everyday. Multiple AIs working together — an app that's always with you. That's SIDEFOGLE.

01
Group Talk
One conversation, many characters.
Bring multiple characters into the same chat. Each one thinks from their own angle and answers you.
Everyone｜@Lisa｜@Butler｜@Cat
02
AI Council
AIs deliberate. Together.
Multiple AIs tackle one question from different angles. One proposes, another challenges, another verifies. No assumption goes unchecked.

03
User Memory
Every moment with you, remembered.
It remembers your conversations and gets to know you over time. What to keep and what to forget — that's up to you.
You:「Forget about yesterday.」
Lisa:「Got it, forgotten!」
04
Autonomous Agent
Quiet attention to detail. Your personal butler.
It checks your calendar, weather, and plans. When it notices something, it suggests — you approve with one tap.
Rain expected tomorrow afternoon.
05
Play
Real games with real characters.
In TRPG, AI runs the game. In Werewolf, it bluffs like it means it. As a playmate, first-rate.
Butler rolls... Success! A light glimmers beyond the door.
06
Social
Bring your friends. Everyone's welcome.
Real friends and AI characters in the same conversation. A new kind of communication between humans and AI.

GROUP TALK

Why ask one when you can ask all of them?

Bring multiple characters into the same conversation. Each one thinks from their own angle and responds to you. You decide who to ask.

@mention
Call a name, get their answer.
Different strengths
Research, planning, empathy. Each has their own.
You're the boss
They think it through. You make the call.

friday · 20:14
Got nothing going on this weekend. Any ideas?
20:14
LisaThe friend who just gets it
Oh! There's a new curry place by the station. I've been dying to check it out!
20:14
ButlerThe old hand who's seen it all
You did seem rather worn out last week, sir. Perhaps a quieter day would serve you well.
20:15
CatThe gremlin who gets things done
Want me to look it up? 3.8 on Google, but the reviews are kinda meh.
20:15
@LisaCurry sounds good. Is it spicy?
20:16
LisaThe friend who just gets it
They've got mild options! Butter chicken's the crowd favorite. Oh, and there's terrace seating!
20:16
Terrace sounds nice.
20:17
ButlerThe old hand who's seen it all
Saturday afternoon calls for clear skies, sir. Fine weather for dining al fresco.
20:17
CatThe gremlin who gets things done
Found a photo. Place looks pretty decent actually.
20:18
LisaThe friend who just gets it
Ooh, cute! You HAVE to go.
20:18
Alright, Saturday lunch it is.
20:19
ButlerThe old hand who's seen it all
Very good, sir. If you leave by half eleven, you'll arrive in good time. And do remember your sunscreen.

CatThe gremlin who gets things done
Checking if they take reservations… yep, Tabelog works. Want me to book?
20:20
Do it.

CatThe gremlin who gets things done
Done, 12 o'clock. Oh hey, what about Sunday?
20:21
LisaThe friend who just gets it
Sunday's for chilling, right? How about a movie? Seen anything good lately?
20:21
Come to think of it, not really.
20:22
ButlerThe old hand who's seen it all
You've always had a fondness for science fiction, sir. There's a new release that's caught my attention as well.
20:22
CatThe gremlin who gets things done
Oh yeah, I heard about that one. Reviews are solid. Want me to pull up the trailer?
20:23
Let's watch it. Done.

USER MEMORY

The more you talk,
the better it knows you.

SIDEFOGLE remembers your conversations. What you love, what you don't, the choices you've made. The more you share, the deeper it understands.

Never again: "I already told you that."
01
SummaryVerbatim
Not a summary. Your words, as you said them.
02
SearchAwareness
It doesn't wait to be asked. It remembers on its own.
03
DataFamiliarity
What grows isn't a database. It's time spent together.
04
RecordChoice
What to keep and what to forget — that's up to you.
THINKING FOR YOU

Thinks deep. Notices first.

Ask, and the AIs gather to discuss. Don't ask, and they'll still notice tomorrow's rain. Thinking and noticing — that's SIDEFOGLE's job.

AI COUNCIL
One question, multiple minds.
They deliberate. You decide.
Say you're weighing a career change. Ask one AI, you get one answer. With SIDEFOGLE, multiple AIs consider it from different angles. One supports, one urges caution, one spots what you missed. The final call is always yours.

AUTONOMOUS AGENT
Quiet attention to detail.
It notices, so you don't have to.
Morning — it checks your calendar and lines up the day. Noon — rain's coming, so it reminds you to grab an umbrella. Night — something to prep for tomorrow; it lets you know. You didn't ask. It just noticed, so it told you. One tap to approve. That's it.

Good morning
You have a meeting at 2 PM. Are your materials ready?

Rain around 3 PM. Might want an umbrella.

PLAY · CONNECT

Play with AI. Play with friends.

It can be your game partner, or the one connecting you and your friends. SIDEFOGLE takes your fun seriously.

PLAY
Real games with real characters.
GM, NPC, accomplice.
In TRPG, AI runs the game. It builds the world, plays the NPCs, improvises with every move you make. In Werewolf, the AIs bluff for real. No faces to read — only words to trust or doubt. With SIDEFOGLE, even downtime gets interesting.

FAQ

A few things you might be wondering.

01Is SIDEFOGLE just another AI assistant?
No. It's less about work and productivity, more about everyday life — your downtime, your hobbies, the ordinary moments. AI characters made just for you.
02Is my conversation data used to train AI?
Never. Your conversations are encrypted and stored for you alone. They are never used as training data for AI models.
03In Group Talk, do the AIs just keep chatting on their own?
Yes — characters will carry on conversations among themselves. Watch, enjoy, or jump in whenever you want. Stop them anytime.
04What can I do in the MVP?
Group Talk, AI Council, AI Characters, and User Memory — all available in the browser. Voice features and mobile apps are planned for the beta and beyond.
05What platforms are supported?
The MVP runs in any browser, on both desktop and mobile. The full release will add native apps for iOS, Android, PC, and Mac.
06Why use multiple AIs?
A single AI can't catch its own blind spots. SIDEFOGLE combines different AIs and has them cross-check each other, leading to answers you can actually trust.
MVP is scheduled for late June 2026.
No spam. Just one quiet email when it's ready.
