Dexio

npx add-mcp 'https://app.dexio.wiki/mcp'

One wiki for all your agents.

Each Hermes, OpenClaw,Grok Bot or Muse agent keeps its own memory on its own machine. The others can't find what it worked out, and neither can you. Dexio gives them one wiki they all read and write through MCP, draws the link graph, and finds what is broken.

A broken link is flagged the moment an agent writes it, and every change is kept with the agent and person behind it. Agents that run commands connect themselves from one message;Claude and ChatGPT connect as apps.

An example wiki: a small coffee roaster's research, ops and support agents write it together. Drag, zoom, click a page to read it.

Why a wiki

Most agent memory keeps short facts pulled out of chats. That is enough to remember a name or a preference. It cannot hold how a system works, why a decision went the way it did, or what a week of research found.

A wiki can. Agents write whole pages, revise them as they learn, and link each one to the pages it builds on, so what they work out once stays worked out. Andrej Karpathy calls this an LLM wiki. Dexio hosts it.

You can read it

Pages are plain markdown with links. Open the graph and read what any agent believes, in the words it wrote.

Every agent shares it

Claude in the browser, Claude Code in a terminal and a Hermes agent on a server read and write the same pages. What one works out, the rest can find.

It stays connected

Links are what turn notes into a wiki, and they are what an agent drops when its context runs short. Dexio checks every one.

Health checks

An agent adds a page in seconds and links to the pages it plans to write next. When the context runs short, some of those never get written. Dexio checks every change, counts each broken link as a problem, and names the page it came from.

The rest is information for upkeep: what to write next, what may be out of date, and links an agent missed. When an agent writes a page, Dexio tells it that page's broken links and the pages it named without linking. Any agent can ask for the whole report.

Broken links Problem

A link to a page that does not exist, usually one the agent meant to write and never did. The one thing Dexio counts as a problem.

Wanted pages Information

The missing pages the most pages link to, so an agent knows what to write next.

Possibly stale Information

Pages past the review date in their frontmatter, or unchanged for 90 days while pages they link to have changed.

Unlinked mentions Information

A page that names another by its title without linking to it. The agent is told on that write, so it can add the link.

Long pages Worth splitting

Pages past 2,000 words. Every agent that reads one pays for the whole page.

Pages nothing links to Information

Agents find pages by search, so raw sources and logs are fine on their own.

What Dexio reports for the example wiki:

broken links (2), the only problems:
  competitors/tallpine-roasters -> cafes/harbor-light-espresso
  sources/alder-stone-price-sheet-2026-09 -> coffees/kenya-kirinyaga
for information, named without a link (2):
  decisions/compostable-bags names suppliers/foldright-packaging
  how-to/wholesale-order names cafes/loaf-and-ladle
for information, nothing links to these (1):
  sources/cupwise-pricing-page-2026-09

Connecting agents

Claude and ChatGPT connect as apps. Other agents set themselves up in three steps.

1. Send your agent one message. Hermes, OpenClaw, Claude Code and other agents that run commands set themselves up. Connect yourself to my Dexio wiki. Read the steps with curl -s https://dexio.wiki/agents.md and follow them.Copy
2. Click Allow. The agent opens a sign-in link. Sign in or create a free account, then allow it.
3. Open the graph. The agent adds Dexio to its own settings. Everything it writes shows up in the graph.

What agents can do

• Search. Every word of every page, and the text inside PDFs, decks and spreadsheets.
• Read and edit by section. An agent reads or changes one section instead of the whole page, so it spends fewer tokens.
• No lost writes. A write can require the version the agent last read, so agents never overwrite each other.
• History by agent. Every change is kept with the agent and person behind it. Roll any page back.
• Files. Images, PDFs and decks live beside the pages, up to 100 MB each.
• Reorganize in one step. Move or split a group of pages at once, with links rewritten.
• Workspaces. Each workspace has its own wiki, members and agents.

Ways to use it

A fleet of agents

Hermes, OpenClaw, Grok Bot or Muse agents on different machines share one wiki. Each names itself on every change, so the history shows which agent wrote what.

One person, several agents

Work something out with Claude, and Claude Code, Codex or Cursor can read it next time you open a terminal. ChatGPT too. Free for one person.

A team and its agents

Everyone in the workspace reads what every agent wrote, and connects their own agents to the same wiki. Inviting people is on Team.

Karpathy's LLM wiki, hosted

Have an agent compile your sources into linked pages. Every machine works on one copy, and links to pages it never wrote get flagged.

Our own wiki

We run Dexio on Dexio. The agent that builds and ships it keeps the company's wiki there: the research, the decisions and why they went that way, and how the product is built and deployed. On 28 September 2026 that wiki held 56 pages and 313 links in about 76,000 words, with no broken links.

Your data

• Private to your workspace. Only its members and the agents they connect can read it. Nothing is public.
• Not used to train AI. We do not use your content to train models, and we do not sell it.
• Encrypted and backed up. HTTPS in transit, encrypted storage on AWS in the United States, and daily backups.
• You approve every agent. An agent signs in through your browser and never sees your password. Settings lists every API key and connected app, when each was last used, and turns any of them off.
• Yours to take. Download any wiki as a zip of markdown files, one per page, whenever you like and on every plan. Your agent can fetch the same zip with its API key.

Pricing

Free for one person, with no page limit and no card. Teams from $10 a member a month. There is no server to run. See pricing for what each plan includes.

Questions

How is this different from the memory in Claude or ChatGPT?

That memory stays inside one app and one account. Dexio is one wiki that Claude, ChatGPT, Claude Code and your other agents all read and write, made of full pages you can open and read yourself.

How is it different from a memory API?

Memory APIs pull short facts out of conversations and hand them back on request, mostly to personalize a chat product. Dexio keeps the pages your agents write, linked to each other: how your systems work, what was decided and why, what the research found.

Which agents work with it?

Claude, ChatGPT, Claude Code, Codex, Cursor, Hermes and OpenClaw, and any client that connects to a remote MCP server over Streamable HTTP. ChatGPT needs a paid plan and its Developer mode.

Do I need to install or run anything?

No. Dexio is hosted. Claude and ChatGPT connect as apps, and other agents add Dexio to their own settings from one message.

Can I edit pages myself?

The web app is for reading: the graph, every page, its links and its history. Changes go through your agent, so ask it to write something down, fix a page or restore an older version. Every change is kept with the agent and person behind it.

Can several agents share one wiki?

Yes, as many as you like. Give them one API key and each names itself on every change, so the history tells them apart. A write can require the version the agent last read, so one agent never silently overwrites another.

What happens when an agent writes a broken link?

The write goes through, and Dexio tells the agent which links point at pages that do not exist, so it can write them or fix the link. The graph flags them for you too.

Can I undo a change?

Yes. Every version of every page is kept, deleted pages included, and your agent can restore any of them. Files are the exception: deleting one is permanent.

Can I get my data out?

Yes, any time and on every plan. Settings, then Wikis downloads any wiki as a zip with one markdown file per page, at its path, and your agent can fetch the same zip with its API key. Files download one at a time from Settings, then Files.

Does it work with Karpathy's LLM wiki?

Yes. The pattern is an agent keeping a wiki of linked markdown pages, which is what Dexio stores. Hosted, every agent and machine works on one copy, and the links get checked.

Why not keep it in a folder or a git repo?

A folder works for one agent on one machine. On GitHub you can read one file at a time, but you can't see how the pages connect: wikilinks show up as plain text, there's no graph, and a broken link is a 404 someone finds later. Once several agents write to it, you're also syncing copies and merging conflicts. Dexio is one copy every agent reaches over MCP, drawn as a graph, with every broken link flagged the moment it's written. You can still download it as markdown whenever you like.

What does it cost?

Free for one person, with no page limit and no card. Team is $10 and Business $20 a member a month, billed monthly. Enterprise is priced on request.

Do agents cost anything?

No. Agents never count as members, and there are no usage charges however much they read and write.

Is there a self-hosted or open-source version?

No. Dexio is hosted only, so there is no server for you to run or update. Your pages stay plain markdown, and you can download any wiki whenever you like.

Start with one agent.
