A second brain for your whole team — in every AI you use
ExpertAnd gives every AI you use — Claude, ChatGPT, Cursor, Slack — one shared brain: your context, your own custom tools, and the judgment of your best people.
It learns from every expert review, so it gets better every week. And it's model-agnostic — your context moves with you to whatever model wins next. We set it up with you, live in two weeks.
Start with your website — free, instant, live. Then add docs, sheets, and your experts.Onboarding 10 founding companies this quarter.
Your context, tools, and learnings live above the model, connected over MCP. Switch clients — Claude today, ChatGPT or Cursor tomorrow — and everything you've taught it comes along. Nothing to migrate. Nothing left behind. Click the tabs, or just watch:
Draft a proposal for Acme Corp — they want the enterprise tier for 250 seats.
→ pricing_lookup enterprise · 250 seats · $48/seat/yr✓
→ brand_voice loaded — brand-guidelines.pdf✓
→ case_studies 2 matched — fintech✓
Here's the draft. I used your current enterprise pricing — $48/seat/yr with the 15% annual commitment discount — your standard security and compliance section, and the Meridian Bank case study, which is the closest match to Acme's profile…
sources: pricing_matrix.xlsx · brand-guidelines.pdf · case-studies/meridian.md
The app changes. Your context, tools, and learnings don't.
Any tool can route its output to the right person before it goes out — your CMO for campaigns, your GC for contracts. They approve, edit, or reject in one click, from Slack or the web.
Every edit is captured as a rule the tool follows from then on. The same correction never has to be made twice — that's how output quality compounds instead of resetting.
Draft → Expert review → Rule learned → Better next draft
“Acme Corp Proposal — Enterprise, 250 seats. Our platform offers 40+ features including…”
“Don't lead with the feature list — open with the ROI story for fintech.”
Saved as a rule in proposal_generator — applies for every teammate, in every AI client, from now on.

Claude · ChatGPT · Cursor · Slack · any MCP client
Every AI can read your documents now — and the outputs still come back generic. Because documents don't contain the way your best people actually work: which case study to lead with, when to hold the price, what legal will never sign off on. That judgment lives in heads, habits, and a thousand private chat threads. Everyone uses AI their own way, and the best of it dies there.
ExpertAnd captures both: your knowledge & the know‑how to use it — turned into tools anyone can run, in any AI, that learn from every expert review.
Explain your company once. Every teammate, every AI surface, works from the same living context.
Every expert review becomes a learned skill. Your tools compound instead of resetting.
Custom tools and connections for your business, launched on Claude, ChatGPT, Cursor — everywhere at once.
Your context, prompts, and tools aren't locked to a model. When a better one ships, your brain moves with you.
Personal memory layers
Give one developer's agent a brain. Powerful — but your company isn't one person, and nobody else benefits from what it learns.
All-in-one AI workspaces
Ask your whole team to move into yet another app, locked to their models. Adoption stalls, and the context stays behind when you leave.
ExpertAnd
One shared brain for the whole company, inside the AI your team already uses, on any model. Set up for you — learning from day one.
We turned Lenny Rachitsky's podcast into a live MCP tool: hundreds of hours of expert knowledge from the best product leaders — organized, structured, and ready to query from Claude or ChatGPT.
This is exactly what we do with your company's knowledge. It's public — connect and ask it anything.
Public MCP tool — connect from any client

“AI finally solves the attribution problem that plagued previous software.”
“Track LLM costs on freemium as marketing costs, not expenses to reduce.”
“Identify expensive services that AI makes affordable, then unbundle them.”
And hundreds more insights from top product leaders.
From scattered documents to your company's own MCP server — custom tools, live everywhere your team works, without changing how they work.
Step 1 / 4
PDFs, images, Google Docs, spreadsheets, entire websites — bring it all in. ExpertAnd organizes your files into structured, tagged knowledge bases that evolve as you add more. New documents, updated playbooks, fresh expertise — always reflected.

PDF, DOCX, images, sheets — anything
Step 2 / 4
Knowledge that just sits there is useless. Chain your pricing logic, brand voice, and case studies into one tool that works the way your best person does — and now everyone runs it. Your domain experts build tools directly, no code. For the founding cohort, we build your first five with you.
Step 3 / 4
Route outputs to the right person before they go live. Your CMO approves marketing copy, your GC reviews legal language. Every review teaches the tool — approval rates compound over time.

Step 4 / 4
Your tools and knowledge bases are instantly available in Claude, ChatGPT, Slack, and any MCP-compatible client. One deployment. Every surface your team uses.
No per-platform configuration. No copy-pasting context. One source of truth for your entire organization.
When an expert approves, edits, or rejects an output, the system analyzes the delta — what changed and why. That loop captures latent knowledge: the judgment in your best people's heads that never made it into any document. It accumulates as learned skills — tone, formatting, facts to include, mistakes to avoid — so month three is meaningfully better than month one.
In Claude, ChatGPT, Slack — wherever you work. No extra steps, no new habits.
Every expert edit is analyzed and turned into a rule the tool applies next time.
Tools converge on the judgment of your best people — and stay there as things change.
Learned skills
From marketing to legal to customer success — every team produces better work when AI understands your business.
On-brand content, proposals, and campaigns that match your voice and positioning.

Proposals, competitive analyses, and pricing quotes grounded in your actual data.
“Draft a proposal for Acme” → pulls pricing, case studies, and positioning
Contracts and compliance docs using your templates, clauses, and approved language.
“Draft an NDA” → uses your template, jurisdiction rules, and standard clauses
PRDs, feedback analysis, and specs that reference your roadmap and research.
“Write a PRD for search” → references roadmap priorities and user research
Accurate customer answers from your knowledge base and product docs.
“Help with billing issue” → pulls pricing tiers, refund policy, past resolutions
Reports, process docs, and workflows built on your SOPs and data sources.

Build and test in your own sandbox before sharing anything.
Share a tool with your whole org the moment it's ready.
Each Slack bot or agent only gets the tools it needs.

Turn what your best people know into composable tools any agent can call. Shared knowledge, guided workflows, review gates — all connected through MCP.
Your agents pull from the same structured knowledge base your team uses. Always current.
Chain knowledge and logic into callable tools: pricing_lookup + brand_voice + case_studies = one function any agent can use.
Route agent outputs through human review gates. Experts approve, edit, or reject — every action audited.

This isn't self-serve software you have to figure out. For our founding cohort, we do the heavy lifting — and you get a system your team is actually using within two weeks.
45 minutes with the founders. We map your highest-value use case and show the platform live — with your documents, not a canned demo. If it's not a fit, you leave with a plan anyway.
We take your documents, playbooks, pricing, and brand guidelines and structure them into living knowledge bases. We interview your best people and capture how they actually decide.
We build five custom tools around your use case and connect them to Claude, ChatGPT, and Slack. Your team starts using them inside the AI they already use — nothing new to learn.
Weekly working sessions for your first month, then continuous improvement: new tools as needs emerge, review workflows tuned to your org, and a system that learns from every expert review.
