Human judgement,
at scale.
Sidechat gives your business a named AI agent that learns your operations, connects to your tools, and gets smarter every week. Not a chatbot. An operating system — built on the science of when AI should lead and when you should.
Good decisions compound. So do bad ones.
When your AI gets each decision even slightly more right, quality compounds multiplicatively across every downstream step. That's Compound Intelligence.
The key: matching the right judgment to the right task. Human where humans are better, AI where AI is better. Our peer-reviewed framework makes the match measurable.
Compound decision advantage over a single business quarter.
Decision quality compounds multiplicatively. A system that gets each step 9% more right doesn't end up 9% better — over a quarter of real decisions, the gap is 100×. That's the math behind Compound Intelligence, published in our peer-reviewed framework.
An AI agent that runs your
operations — and knows when to ask you.
Your Sidechat agent handles CRM, research, scheduling, communications, and document management. It connects to your tools, learns your business over months, and gets measurably better every cycle.
It maps your judgement.
Sidechat audits your operation and identifies which decisions should be yours and which should be the agent's. No guesswork.
It works where you work.
Slack. Email. WhatsApp. Browser. Your agent keeps the same context everywhere — start a conversation in Slack, finish it over email.
It compounds every week.
Month 1 is good. Month 3 is better. Every cycle, the agent learns your contacts, processes, and preferences. Tasks that needed your review last month run autonomously this month.
From setup to autonomous.
We configure your workspace. Link tools, set permissions, onboard your team.
Your agent handles real tasks — drafts, scheduling, research — with your review.
Workflows run end-to-end. The agent learns your preferences, contacts, and patterns.
Compound intelligence. What took your team hours now runs autonomously in minutes.
Set up in minutes. Lives inside your business.

We built the first AI platform with a theory of when AI should — and shouldn't — act.
Sidechat founder Le Zhang published a framework that cracked a paradox: why does human-AI collaboration create massive value sometimes and destroy it other times?
The answer: it depends on whether the human's judgement exceeds the AI's on that specific task. Right match — intelligence compounds. Wrong match — errors compound.
We call it Compound Intelligence. It's not a slogan — it's peer-reviewed math. And every Sidechat agent is built on it.
The foundational research behind Sidechat's Compound Intelligence methodology.
Real reactions from real users.
“I would pay $2,000/mo for this. It integrated my calendar, Outlook, and Notion — I was astonished.”
“It’s crazy. It really is like you wrote some custom software.”
“I would probably pay like $500 a month for this.”
“It’s so smart... very very fast, very easy.”
“I actually do like that it shows what it’s doing.”
“side.chat is literally helping me teach myself SQL.”
“Dude side chat onboarding is so clean. I named my guy Itachi.”
“My teammate helped me organize my Drive into folders.”
“My teammate came back with 6 categories of starred stuff. Useful.”
“WOW. Thank you — I needed this.”
“I just asked it to do so and it figured it out.”
“Claude couldn’t — it didn’t have write capabilities.”
“Sidechat agents are more personalized and have more agency.”
See exactly where AI is helping your business — and where it's hurting.
The Compound Intelligence Assessment maps your entire operation in one session. Which decisions create value. Which ones destroy it. Where to deploy agents. Where to keep humans. Clear, specific, actionable.
For qualified operators. Because once you see the map, the next step is obvious.
