MyContext
Get started

Save it once.
Dex
remembers the rest.

MyContext is shared memory for you and your AI agents. The plans you agree with Claude Code, the decisions you reach with Codex and the answers worth keeping from ChatGPT live next to the links, notes and files you save — every version kept. Dex, the librarian who lives in it, reads and files it all, so the next agent picks up where the last one stopped.

For agents

Connect your agents

Claude Code, Codex, ChatGPT and other MCP clients read the same context and save their plans back — after you approve them in your browser.

Read https://mycontext.work/llms.txt and connect to my MyContext vault through the MCP server. Start the OAuth flow and ask me to approve access in my browser.

Why MyContext

Four promises, kept from day one.

What you read and what you work out with your agents adds up to years of context. These are the terms Dex keeps it under.

It's free

Free, and generous with it.

Your first 1,000 entries cost nothing — every feature included. A small plan unlocks more room later.

See pricing

Bring your data

Import everything you've already saved.

Bookmarks files, Karakeep exports, Pocket CSVs and OPML. Your folders stay folders; Dex starts reading straight away.

How import works

Own your data

It's yours. Private by default, portable by design.

Private by default. Export everything as JSON or delete it for good, any time.

Read our privacy promise

Built for agents

Every agent starts where the last one stopped.

Claude Code, Codex and ChatGPT connect through our MCP server. They read your context in one call, save plans and decisions back, and every edit is kept as a version you can roll back — once you approve access.

How it works

Three steps. The middle one is not your job.

  1. 01

    Save

    Paste a link, drop a file, use the extension — or tell your agent to save the plan you just agreed on.

  2. 02

    Dex reads

    Tags, the right folder and a semantic index in seconds, a TL;DR whenever you ask — and every later edit kept as a version.

  3. 03

    Find or ask

    Search by meaning or #tag, ask Dex, or let any connected agent pick up where you left off.

What Dex does

A librarian who has read everything you and your agents keep.

Everything below is included on the free plan. Nothing is locked behind a paywall.

Every link is fetched and cleaned into a reader view; notes, PDFs, images and voice notes are read too, and the full text stays searchable. Want the gist? Press Summarise for a TL;DR on the spot — written only when you ask, so nothing is spent on what you never open.

Every save lands in the folder it belongs to, with three to six tags that reuse the ones you already have. Rename or merge a tag once and it changes everywhere; move anything back and Dex remembers.

Ask “what did we decide about pricing?” and Dex searches, opens the right files and replies with citations to your own vault — never the open web.

Ask Claude Code, Codex or ChatGPT to save the plan you agreed on, a decision and why, or a summary of the session. It lands as Markdown in the folder it belongs to, and every change is kept as a version — who made it, when and what changed — so you can compare, roll back and hand the work to the next agent.

Mark a passage in any article, note or PDF. “Explain this” gives a grounded answer from the surrounding text — simpler, in context, or in Dex's own words.

Follow any site's RSS, Atom or JSON feed: new posts are saved, tagged and filed like everything else. Reading time and resume-where-you-left-off on every card, and Tonight's picks when you have 30 minutes.

A browser extension for Chrome and Firefox, an app you can install on your phone, and a share button that saves from any other app.

Your agents connect natively through MyContext's MCP server, with secure sign-in and explicit approval. One call gives them your rules, profile and folder map; every vault is a file system they already understand — people, projects, meetings, decisions — so they search and read your context, follow your skills, and write Markdown and HTML back without overwriting each other.

Questions

The things people ask before they move in.

Short answers here; the long ones live on the pricing, import, agents and privacy pages.

Is this a bookmark manager?

Saving links is one part of it. MyContext is shared memory for you and the AI agents you work with: the plans you make with Claude Code, the decisions you reach with Codex and the answers worth keeping from ChatGPT live in the same private vault as your links, notes and files. Dex reads and files all of it, and every agent you connect reads the same context.

Can my agents save the plans and decisions we work out together?

Yes. Connect Claude Code, Codex, ChatGPT or another MCP client and ask it to save the plan, the decision and why, or a summary of the session. It's written as Markdown into the folder that fits — projects/, decisions/, meetings/ — read and indexed by Dex, and every later edit is kept as a version with who made it and when, so you can compare or roll back. You can also paste a conversation into a note, or save it from the extension.

What does “built for AI agents” mean?

MyContext has a live MCP server at mycontext.work/mcp. A compatible agent discovers sign-in automatically, you approve access in your browser, and it can then load your rules and context in one call, search, read and write the vaults you can access, and follow the skills you've written down. The REST API remains available for scripts and shortcuts.

What counts as an entry?

An entry is one thing you've saved: a link, a note, a PDF or image, a page saved from the browser extension, or a post pulled in by a feed you follow. Tags, folders, highlights, Dex's summaries and the files Dex writes for you (folder indexes and the daily activity log) never count.

Is MyContext really free?

Yes. While MyContext is in beta everyone is on the Free plan and nothing is paywalled. When Plus launches, Free keeps every feature and its 1,000-entry allowance — it isn't a trial that expires.

Can I import from Karakeep, Pocket or my browser?

Yes. MyContext reads browser bookmark files (Chrome, Firefox, Safari, Edge, Brave, Arc and any browser that exports Netscape HTML), Karakeep JSON exports, Pocket CSV exports, OPML feed lists and plain lists of links. Duplicates are recognised and your folders arrive as folders in Files.

Who can see what I save?

Only you and the agents you approve, unless you choose to share a folder, note or page with a link — and every link expires when you say. Your vault isn't visible to other users or to search engines. Dex processes your entries to produce tags, a search index, the summaries you ask for and answers — nothing is sold, and there are no ads.

Can I leave and take everything with me?

Yes. Settings → Import & export gives you your whole vault as one JSON file — links, notes, tags, folders and any summaries Dex wrote — at any time. You can also delete anything permanently, whenever you like.

How is this different from Karakeep, Pocket or Raindrop?

MyContext started as an AI-native rebuild of the open-source Karakeep idea and grew into memory your agents share. Every entry is read, tagged, filed and indexed by meaning the moment it's saved; you can ask questions across the whole vault and get cited answers; and the same vault is open to your agents through MCP, with a version history of everything they write.

“Pick up the auth plan we made in Claude Code yesterday.”

Say it to Codex, ChatGPT or Dex and each finds the same plan, the decisions behind it and every version since — because they all read the same vault.
