Capabilities

What your assistant can do

Find the right files, check the source, and leave with a useful export or a workflow draft to review.

Find the document you remember

Search by sender, filename, subject, and date. On Pro, describe what you remember and search by meaning across extracted, indexed attachments.

search

Extract exactly the fields you need

Request fields from supported PDFs, scans, images, and office files. Results include source excerpts and page references so you can check missing or uncertain values.

extract_fields

Prepare a handoff with the originals

Keep a selected collection, review extracted details, and prepare a CSV or Excel export with source references. Retrieve original files with separate download permission.

export_collection

Separate repeats from revisions

Identify exact duplicate files in a collection, even when names differ. Compare extracted fields in selected documents with both sources and uncertain values visible.

compare_documents

Draft an automation by describing it

Say what should happen to future attachments. The draft lands in Dioveo for you to review, adjust and activate.

You stay in control

Every assistant asks for approval on a Dioveo screen that lists its permissions. Sensitive values are redacted by default, and access can be revoked.

Setup

Connect it in three steps

Every assistant needs the same thing: Dioveo's server URL. Paste it where the assistant asks for a connector or MCP server, then approve the access when Dioveo asks you.

Claude

Web, desktop and mobile

  1. 1In Claude on the web, open Customize, then Connectors, and click the plus button.
  2. 2Choose “Add custom connector”, name it Dioveo, paste the server URL, and click Add.
  3. 3Click Connect next to Dioveo and approve the permissions on the Dioveo screen.

Connectors added on the web are also available in Claude desktop and mobile. Team and Enterprise workspaces may require an owner to add the connector first.

Using another assistant? If it accepts a remote MCP server URL with OAuth sign-in, the same URL works.

Safeguards

What it can and cannot do

The limits are the point. Each one holds whether you ask from Claude, ChatGPT, or anything else.

  • You approve every connectionEach assistant is approved once, on a Dioveo screen that names it and lists exactly what it asked for. Your Google credentials never reach it.
  • Nothing in Gmail changesSearching and reading never modify your emails or files. Your mailbox stays exactly as it is.
  • Sensitive values are redactedRecognized bank details, identification numbers and similar values are hidden by default. Releasing them takes an explicit confirmation that Dioveo records without copying the values into its audit log.
  • Document text stays in your cacheText read from a document is kept for reuse for up to 12 months. Ask the assistant to clear it, or delete your account, and it is gone.
  • Automations wait for youAutomations arrive as drafts in Dioveo. Nothing runs until you review and activate it.

Included in your plan

Attachment metadata search is included on Free and Pro. Search by meaning is a Pro feature for extracted, indexed attachments, with separate indexing and query limits. Reading raw document text for the first time uses one document read from your monthly allowance: 10 on Free and 500 on Pro. Structured field extraction uses the included monthly AI processing allowance. Identical completed requests are cached, and a failed document read is refunded.

Prompts

Things to ask once it is connected

Choose a prompt and adapt the dates, senders, and selection to your Gmail. Search by meaning requires Pro and extracted, indexed attachments. Review uncertain fields before using them.

  • “Find invoice attachments received from 1 April to 30 June 2026. Let me review the selection, put the selected files in a collection, flag exact duplicates and uncertain fields, and prepare an Excel export plus the originals.”
  • “Search my extracted, indexed attachments for the document about replacing a laptop battery that arrived between March and May 2026. Show me the relevant passage and who sent it. Tell me if any attachments in that period are not indexed.”
  • “Check my selected collection for exact duplicate files. Compare the original invoice with the revised one, show changed extracted fields with both sources, and flag anything uncertain. Keep all originals.”
  • “Compare these two supplier quotes for price, currency, delivery date, and payment terms. Cite both documents and flag anything you cannot verify.”
  • “Collect my attached EV charging invoices for August 2026. Extract provider, date, energy, total, and currency where supported by the source, then export a review sheet.”
  • “Find the attached receipt for my washing machine bought in 2025. Show the purchase date and product details from the source, then retrieve the original.”
  • “Find the attached hotel, rail, and rental receipts for my Lyon trip from 8 to 12 June 2026. Let me review the selection, then export the documents and a spreadsheet with source references.”
  • “On Pro, search my indexed English, French, and Arabic invoice attachments for office equipment. Show the relevant source passages, preserve the original currency, and tell me about missing search coverage.”
  • “Draft a workflow that saves future invoices from [email protected] to my chosen Google Drive, OneDrive, or Dropbox folder. Let me review and activate it in Dioveo.”

FAQ

Frequently asked questions

Which assistants work with Dioveo?
Dioveo has setup guides for Claude, Claude Code, ChatGPT, Codex and Cursor. Any other client that supports remote Streamable HTTP servers and standard MCP OAuth can use the same server URL.
Is it included in my plan?
Yes. Attachment metadata search is included on Free and Pro. Search by meaning is a Pro feature for extracted, indexed attachments, with separate indexing and query limits. Reading raw document text for the first time uses one document read from your monthly allowance: 10 on Free and 500 on Pro. Structured field extraction uses the plan's included monthly AI processing allowance. Identical completed requests are cached, and failed document reads are refunded.
Can an assistant change, send or delete anything?
Your assistant can create collections, prepare exports, retrieve selected originals with separate permission, and save workflow drafts. It cannot send email or label or delete Gmail messages. A workflow draft does nothing until you review and activate it in Dioveo.
What happens to sensitive information?
Dioveo redacts recognized bank details, identification numbers, birth dates, addresses, contact details, and strongly identified health or payroll data by default. Unredacted values are returned only when you explicitly confirm that release, and the confirmation is recorded without copying the values into the audit log.
What is MCP?
The Model Context Protocol is the open standard assistants use to call outside tools. Dioveo runs an MCP server, so any assistant that speaks it can use your attachment index once you approve it.
How do I disconnect an assistant?
In Dioveo, open Connections and revoke it under AI assistants, or remove the connector inside the assistant. Access ends at its next token refresh, within 15 minutes.
Does it work on my phone?
Claude's mobile apps use the connectors you added on the web. Adding one happens on the web or the desktop app.
