Deck
Deck is an AI assistant that lives at its own email address. CC it on a thread, forward it a file, or hand it a recurring routine. No app, no plugin, and it replies only to you.
What is Deck?
Deck is an AI assistant published by Deck, Inc. that does not live in an app or a browser tab: it lives at an email address of its own. You pick a name in the settings, and the assistant is issued an address such as june@agent.hellodeck.ai. From then on you work with it the way you work with a colleague - you CC it on a thread, you forward it a file, or you write to it directly. Crucially, it answers only you. Even when it sits on the CC line of a conversation with clients or teammates, its reply never reaches the rest of the thread.
Three building blocks carry the product. The Email Assistant is the address itself, handling forwards, threads and direct questions. Scheduled Tasks are routines that run hourly, daily, on weekdays, weekly or once, and email you the output - a brief of the day's meetings, a weekly read on an account, a watch on a competitor. Vigil is the proactive layer: set to Medium or High, it surfaces deals that have gone quiet, prep you have not booked, or a birthday on next week's call.
It works with any email provider - Gmail, Outlook, iCloud, a work address - because forwarding is the only protocol involved. Nothing is installed: no plugin, no extension, no mandatory permission. Inbox access is optional and stays off until you connect Google Workspace or Microsoft 365 yourself. A web workspace at app.hellodeck.ai holds the inbox, contacts, projects and tasks, and optional integrations bring in Notion, HubSpot, Fireflies and Granola.
The assistant accepts PDF, Word, Excel, PowerPoint, plain text and Markdown - up to 100 MB on direct upload, 25 MB by email - and returns drafts, summaries, briefs and native Word or PowerPoint files. A library of ready-made routines covers morning briefs, competitor watches, price alerts, board prep and weekly reviews. A dedicated vertical, Deck Finance, targets investment and deal teams with IC memos, model tie-outs, diligence summaries and deal-term extraction. The publisher claims setup takes about two minutes and the first reply comes back in under thirty seconds.
What it does
- Follows any thread you CC it on and privately flags what needs your attention
- Reads forwarded emails and attachments, then files them against the right project
- Drafts replies in your own writing style, ready for you to review and send
- Runs scheduled routines - morning briefs, weekly digests, overnight monitoring - and emails you the result
- Researches companies, people, competitors, prices, RFPs and grants on request or on a cadence
- Produces native Word documents and PowerPoint decks from your files and notes
- Watches your work proactively with Vigil and nudges you about stale threads and approaching deadlines
When to use Deck / When not to
A quick filter to help you decide if Deck is the right fit.
When to use Deck
- Founders and small-business owners who run the company from an inbox and have no assistant
- Sales, partnership and customer-success teams chasing follow-ups across dozens of live threads
- Investors, deal teams and finance departments preparing memos, tie-outs and recurring reports
- Lawyers, paralegals and contract managers juggling document review across several matters
- Realtors, property managers and other client-facing professionals drowning in transaction email
When not to use Deck
- Anyone who wants the assistant to answer clients or colleagues directly, since it only ever writes back to you
- Teams needing a mobile app or a browser extension, as Deck runs over web and email only
- Organisations that require a signed DPA, a named EU representative or a stated hosting country
- Developers looking for a public API and developer documentation, which the product does not publish
- Non-English-speaking users, since the interface, the site and the documentation exist only in English
How to use Deck
A typical end-to-end flow, from setup to results.
- Create an account at app.hellodeck.ai/sign-up - no credit card is requested

- Turn on Vigil and set the monitoring level to Medium or High
- Set up auto-forwarding from Gmail or Outlook if you want threads routed to it without thinking
Pros & Cons
Pros
- Nothing to install and nothing to learn: CC and forward are gestures everyone already uses
- Works with any email provider, from Gmail and Outlook to iCloud and a plain work address
- Mailbox access is optional and revocable, and the assistant never writes to anyone but you
- The publisher states plainly that customer data trains neither its own models nor any third-party model
- A permanent free plan and a 14-day Pro trial with no credit card make trying it cost-free
- Entry pricing at 14 USD a month sits well below the category's enterprise tiers
- Scheduled routines and a ready-made routine library turn recurring work into background work
Cons
- The publisher is opaque: no postal address, no named founders, nothing beyond the name Deck, Inc.
- No Data Processing Agreement, no Article 27 EU representative and no data protection officer
- No hosting country or region is disclosed; data residency is only an enterprise talking point
- SOC 2 is asserted in the footer with no report, no stated type and no trust centre
- Pricing contradicts itself: the site says 14 and 29 USD with a 14-day trial, the help centre says 34.99 and 29.99 USD with a 7-day trial
- Only six documented integrations, no public API and no developer documentation
- No mobile app, no browser extension, English only, and the assistant address can never be changed

Data, GDPR & hosting
A consolidated view of how Deck handles your data.
GDPR overview
Every page footer claims SOC 2 and GDPR compliance, and the privacy policy (effective 31 July 2025, last updated 14 July 2026) does carry real substance: a named list of ten service providers, a detailed cookie table with retention periods, a consent banner that loads analytics and advertising only after acceptance, a full CCPA/CPRA section, and an explicit paragraph acknowledging that users in jurisdictions such as the European Union hold additional access, rectification and erasure rights. The gaps are just as clear. There is no Article 27 EU representative, no data protection officer, no published or offered Data Processing Agreement, and no hosting country or region is disclosed. Governing law is Delaware, with exclusive jurisdiction in Delaware courts. The minimum age is 16. All rights requests go to a single address, support@hellodeck.ai.
Who owns the data?
The terms are explicit: you keep ownership of everything you upload. By submitting content you grant Deck, Inc. a limited, non-exclusive licence to process, store and display it, and that licence is restricted to delivering the service itself. The publisher's own documentation adds that data sits on encrypted infrastructure scoped to your account, so nobody else sees what you put in. Deck states that customer data never trains its models or any third-party model. Access can be narrowed: the assistant sees only what you forward or CC unless you deliberately connect a mailbox. Deleting a project cascades to its files and chats, and account deletion is requested by email to support.
Reuse rights
You may reuse your own content freely: ownership stays with you, and nothing in the terms restricts what you do with the drafts, briefs, reports, Word documents or PowerPoint decks the assistant returns. Deck's own licence runs the other way and is narrow, covering only processing, storage and display for the purpose of running the service. Deck's material is treated separately: the software, trademarks and designs belong to the publisher or its licensors, and may not be copied, modified or redistributed without permission. The privacy policy states that personal information is never sold, that uploaded documents are processed only to produce the outputs you asked for, and lists the vendors involved, including OpenAI for generation and Vercel for hosting.
Data retention & training
Hosting summary
Deck names no hosting country and no hosting region anywhere on its site, in its terms or in its documentation. The privacy policy identifies Vercel as the hosting provider and OpenAI as the generation provider, alongside eight other vendors, but stops there. The enterprise demo page lists "compliance and data residency" as a discussion topic without committing to any jurisdiction, and the Deck Finance FAQ adds that enterprise customers can deploy inside their own infrastructure - which implies that the standard offer does not let you choose where data sits. On the technical side, the site's domain resolves to a United States address on an Amazon anycast node, though that describes the marketing site rather than the application backend. Security claims stay qualitative: administrative, technical and physical safeguards in the policy, encrypted infrastructure scoped to the account in the help centre, and a SOC 2 badge in the footer with no report attached. Anyone with a data residency requirement will have to raise it with sales.
Things to keep in mind
Risks and trade-offs to weigh before adopting Deck.
- An assistant that drafts in your voice makes it easy to send replies you have not really read
- Handing over follow-up memory can quietly erode your own grip on who is waiting on what
- Connecting Gmail or Microsoft 365 grants broad access - decide deliberately rather than by habit
- Content is processed by a third-party model provider named as OpenAI, which matters for confidential material
- No DPA, no EU representative and no disclosed hosting country leave European compliance unresolved
- The publisher's identity is thin - no address, no named officers - so recourse is hard to assess
- The site's own interactive product guide warns not to share sensitive information with it
Setup & Integrations
Technical difficulty
Very low. There is nothing to download, no plugin and no extension, and no permission is mandatory. Three steps are enough: create an account, name your assistant to be issued its address, and send it a first email or CC it on a thread. The publisher claims about two minutes to set up and a first reply in under thirty seconds. Optional OAuth connections to Google, Microsoft, Notion, HubSpot, Fireflies or Granola take a few clicks each. Only the advanced options - auto-forwarding rules, webhook-driven context, scheduled snapshots - call for a comfortable user, and none of them are required.

Should you pick Deck?
Deck answers a real problem with an unusually simple idea: instead of asking you to open another app, it takes an email address and behaves like a colleague you copy in. Everything that follows from that choice works in its favour. There is nothing to install, it fits any mail provider, mailbox access stays optional, and the assistant never writes to anyone but you - a boundary that matters when the thread contains a client. Around that core, scheduled routines and the Vigil monitoring layer turn recurring work into something that simply arrives, and native Word and PowerPoint output means the result is usable rather than merely readable.
The reservations are about the publisher rather than the product. Deck, Inc. discloses no postal address and no founders. SOC 2 and GDPR compliance are claimed in the footer, but there is no report, no stated audit type, no Data Processing Agreement, no Article 27 EU representative and no hosting country. The privacy policy does name ten processors, including OpenAI and Vercel, which is more than many peers offer, yet a European controller would still be short of what a procurement review normally requires. The help centre also contradicts the site on price and trial length, which suggests documentation that has drifted.
The company is young - the domain was registered in July 2025 and first archived a month later - and no funding is publicly attributable to it. That argues for caution on anything sensitive, not for staying away: with a permanent free plan and a 14-day trial without a card, the cost of forming your own opinion is nothing. Try it on ordinary work first, and settle the compliance questions before it touches confidential material.
