How Contexel works.
A few minutes to set up. Then just talk to your AI.
Get started
Contexel is one memory for all the AI apps you use. Tell one of them something once, and the others, and the people you share with, can find it later.
- Sign in to Contexel. You start with a private workspace of your own.
- Add Contexel to your AI app. In Claude or ChatGPT, add a custom connector and paste the address
https://contexel.ai/mcp. Then sign in with your browser when the app asks.
That's it. Ask your AI to remember something, then ask about it later from any connected app.
Tip: tell your AI to use it. It makes saving and lookups more reliable. In Claude, open Settings, then Instructions for Claude. In ChatGPT, open Settings, then Personalization, then Custom instructions. Paste this: When I ask you to remember something, also save it to Contexel. Before you answer a question about me, my family, or my work, check Contexel.
Connect your AI app
Every app uses the same address, so they all share one memory. Pick yours for the steps.
Using Cursor or VS Code? Add Contexel in one click. The app opens and asks you to confirm, then you sign in with your browser. The link holds only the address, never a key.
Any other app that supports MCP, the standard way AI apps connect to outside services, works the same way: add https://contexel.ai/mcp and sign in. The console's Connect tab shows the exact settings for each app.
Using it
There's nothing new to learn. Talk to your AI as usual.
- "Remember that..."Your AI saves it to Contexel.
- Ask a question.When the answer depends on something you saved, your AI looks it up and answers from what you saved.
- "That's out of date..."Your AI fixes the memory. The old version stays in its history.
Sharing
Memories live in workspaces. Your private workspace is yours. Create a shared one for your team, a client or your family, and choose who gets in.
- Can edit.Their AI can look things up and save or change memories.
- Can view.Their AI can look things up, but can't change anything.
Your data
- Encrypted, in the United States.Every organization's data is encrypted at rest with a key dedicated to it, from the moment it is created, and stored on our own servers in the United States. Contexel manages the key so search can run, which means we can technically access your data.
- Never sold, never used for training.We never sell your data, never use it for advertising, and never use it to train AI models.
- Yours to take.Download every memory as plain text files from the console, any time.
Please don't store passwords, health information or payment card details. The privacy policy has the full detail, and the security page explains how it is all protected.
For IT admins
Contexel signs people in through their browser with standard OAuth (email, Google or GitHub), so there are no shared keys to hand out. Access is set per workspace and per person. Every change is recorded. The details reviewers ask for are below.
Tools and what they can change
Each tool is labeled for the app as read-only or as one that changes memory, so apps can ask before anything is saved. None reach outside Contexel.
| Tool | What it does | Changes memory |
|---|---|---|
get_context | Looks up the memories that bear on a question or task, each with who saved it, where it came from and when. | No |
search | Lists the memories that match a topic. | No |
fetch | Reads one memory in full. | No |
status | Shows what is saved and whether search is up to date. | No |
digest | Catches you up on what changed since a day or your last visit, and who saved each change. | No |
remember | Saves a note, decision, rule or lesson, in plain words. | Adds |
observe | The older name for remember, kept so existing setups still work. | Adds |
correct | Fixes a memory that is wrong, or removes one that no longer applies. Earlier versions stay in the history. | Yes |
suggestions | Shows the changes waiting for your decision, and accepts or rejects one when you say so. | Yes |
A note saved with remember is filed as written, unless your organization has AI distillation and the workspace owner left it on: then the note is sent to Anthropic to be filed into a lasting memory.
These are the everyday tools every connection gets. For the full set of 25, add ?tools=all to the address. The extras include explain (why a memory did or didn't come back), cite (exact quotes from a memory), audit (finds conflicting, stale or unlinked memories) and my_settings (reads or changes your own time zone; your AI app asks you before a change). Sharing, workspaces and billing stay in the console.
Who can do what
A workspace's owner creates it, invites people, chooses their access (Can view or Can edit) and can delete it. Can edit saves and changes memories directly, with no approval step, so give it only to people you fully trust. Access tokens, for apps that can't sign in with a browser, use the same two levels. Organization admins can reach any workspace in their organization. Every time they do, it is recorded in the activity log, and when it is someone's private workspace, its owner is told who opened it and when.
How answers are chosen, and which memory wins
Your AI gets only the memories that clearly match the question, each whole, with who saved it, where it came from and when. Each answer says how many loose matches were left out, and says so when nothing fits. When two memories disagree, a memory saved as a required rule outranks a preference, and a newer memory can replace an older one, which stays in the history. These rules apply within a workspace, never across two.
Data handling, AI distillation and the activity log
- Where it lives.Amazon Web Services in Oregon, over HTTPS, with each organization's data kept separate.
- Secrets are blanked.Common secrets such as API keys, tokens and passwords in connection strings are replaced before anything is saved, as a safety net.
- AI distillation.Off unless we turned it on for your organization; until then notes are filed word for word on our own servers and nothing is sent anywhere. When it is on, notes go to Anthropic, an outside AI provider, to be filed into tidy memories. Anthropic doesn't train on them, every send is logged, and a workspace owner can turn it off in the workspace's settings.
- Activity log.Saves, approvals, exports and access changes, kept for 6 years in a log that shows if anyone has altered it. It holds IDs, counts and times, never your content.
Ask support@contexel.ai for an export of your organization's activity log.
Export and deletion
"Download my data" in the console gives each person every workspace they can read as plain text files. Owners can delete a workspace, and privacy@contexel.ai deletes a whole account on request.
