Gyld connects knowledge, systems, and context so AI can actually work.

Gyld indexes the data you already work with — email, chat, docs, CRM, invoices — into one company brain, then serves it to Claude, ChatGPT, and Cursor. Answers come from real deals, threads, and numbers.

What did we agree with Halverson on pricing?

Why context

The answer already exists. Your agent just can’t see it.

It’s in a thread from March, a line item in QuickBooks, a doc nobody linked. Gyld indexes what you choose into one company brain and hands it to your agent the moment it asks.

Without your context

Why did we go with Everpure over Kestrel?

I don’t have anything on Everpure or Kestrel. If you paste the evaluation doc and the thread where it was decided, I can summarize the trade-offs for you.

With your company brain

Why did we go with Everpure over Kestrel?

Price came within 4%, so it turned on support: Kestrel wouldn’t commit to the four-hour SLA. Dana made the call in the March 12 review. The EU data-residency risk you raised there is still open.

NotionSlackNotion doc + Slack thread
01

Every answer carries its source

The thread, record or file it came from, attached to the claim. You can check it without leaving the answer.

02

You stop pasting context into prompts

No dumping the thread, the doc and the CSV export into the chat before you can ask anything. The agent goes and gets what it needs.

03

It holds the why, not just the file

Decisions, who agreed to what, what got promised and when. Mined out of mail and chat, where those things actually get settled.

04

Connect once and every agent has it

Claude, ChatGPT, Cursor and Codex read the same brain through one URL. Nothing to fine-tune, no retrieval pipeline of your own to maintain, and it stays current as new mail, deals and invoices land.

Use cases

A brain for any kind of work.

Ask in plain language. Every answer is grounded in your company's own threads, records, and numbers — and says where it came from.

FAQ

What Gyld is, in plain terms.

Open a question to see the answer.

What does Gyld actually do?

It indexes the apps you already work in (mail, chat, docs, CRM, invoices) into one company brain, then serves that brain to your AI tools over a single MCP URL. Ask what you promised Acme and the answer comes back from the real thread, with the source attached.

What is a company brain?

A company brain is one searchable store of what your business knows: your threads, files and records, plus the decisions and commitments buried in them. You choose what goes into it.

What is a business context layer for AI?

A business context layer sits between your company systems and your AI tools. It keeps your data current and permissioned, and exposes it over the Model Context Protocol so any agent can read it.

Which apps can I connect?

Gmail, Outlook, Slack, Notion, Drive, OneDrive, Dropbox, HubSpot, Salesforce, QuickBooks, Stripe, Shopify, GitHub and around thirty more, plus a read-only line to your own database. You pick the accounts, channels, folders and tables that feed the brain.

Which AI tools can use it?

Anything that speaks the Model Context Protocol: Claude, Claude Code, ChatGPT, Cursor, Codex, Gemini. One URL, added once, and they all read the same brain.

Who on my team can see what?

The brain mirrors the permissions of the source, so a private channel or a restricted folder stays restricted to the people who already had it. Anything Gyld cannot confirm your access to is not returned.

Do you train on my data?

No. Your data is never sold and never used to train generalized models. Tokens are encrypted at rest with AES-256-GCM, and workspace isolation is checked on every query.

Can I just build this myself?

You can put a RAG pipeline together in-house, and it will retrieve fragments. Gyld permanently owns the connectors, the indexing, the freshness and the permission model, so your team wires agents to the brain instead of maintaining ETL forever.

How long does setup take?

A couple of minutes to connect the first app, and indexing starts immediately. Nothing is migrated: Gyld reads through OAuth with the minimum scopes for what you chose to index, and your tools stay where they are.

Something we didn’t cover? Ask it on the demo.

Get started

It takes minutes to set up.

Connect Gmail or Slack, watch the brain fill in, then ask what you promised Acme. The answer comes back with the thread attached.
