Pros

Competitor

Pros

Windows Search X1 Search indexes email, cloud drives, and chat platforms in one place, while Windows Search mainly focuses on local files. Power users handling PST archives and M365 data get faster, more granular filtering. The refine columns and preview pane make large inboxes easier to navigate.
Copernic Desktop Search X1 Search connects deeply with Slack and Microsoft Teams, giving broader collaboration coverage. Its fast-as-you-type engine feels more responsive with very large mail archives. Many professionals prefer its preview quality and metadata filters for handling complex searches.
dtSearch Desktop dtSearch targets legal and technical users, but X1 Search offers a simpler interface for everyday business workflows. It balances speed and usability, making it easier for non-technical staff to search Outlook, Gmail, and cloud drives without complex query syntax.
Everything (Voidtools) Everything excels at file name search, yet it doesn’t index email or cloud content. X1 Search covers attachments, archived mail, and collaboration chats, making it more suitable for knowledge workers managing both local and cloud-based information.
Lookeen Compared to Lookeen, X1 Search provides broader cloud integrations and Slack support. Users handling both Google Workspace and M365 environments benefit from its unified indexing and consistent preview experience across data types.

Cons

Competitor

Cons

Windows Search Windows Search comes built into the OS at no extra cost, while X1 Search requires a paid license. For users who only need quick local file lookups, the added features may feel unnecessary and more complex than the default option.
Copernic Desktop Search Copernic can feel lighter for strictly desktop-based searches. X1 Search’s broader integrations and indexing depth may demand more system resources during initial indexing, especially on older machines.
dtSearch Desktop dtSearch offers highly advanced Boolean and proximity search controls suited for legal discovery. X1 Search focuses more on usability, so power users needing complex query scripting may find fewer specialized options.
Everything (Voidtools) Everything delivers near-instant file name results with minimal system impact. X1 Search, while broader in scope, requires indexing emails and cloud data, which can take time to set up and maintain.
Lookeen Lookeen integrates tightly with Microsoft ecosystems and may feel more native for Outlook-heavy environments. X1 Search adds cross-platform breadth, but organizations fully standardized on Microsoft tools might not use all its integrations.

Reviews

  • G2 Review (Rating: 4.5/5): Users like how X1 Search pulls results from Microsoft 365, Google Workspace, Slack, and local files into one “lightning-fast” interface. The “fast-as-you-type” search and full-fidelity previews help them find emails, chats, and documents instantly without jumping between apps.
  • Capterra Review (Rating: 4.6/5): One reviewer with 72,000 files said the indexing engine delivered “instantaneous results” and kept the index size to 758MB with no visible performance hit. Others like that X1 finds old emails or even a specific sentence buried in thousands of files, though a few mention the price and occasional surprise search window pop-ups.
  • softwarefinder.com Review: All 9 verified customers gave 5 stars, with perfect 10/10 scores for ease of use, value for money, and customer support, and a 9/10 for functionality, showing consistently high satisfaction across the board.
  • mcleanco.com Review: An IT professional described X1 Search as “Easy & effective” and highlighted it as a “Great way to search,” giving it a 9/10 likelihood to recommend.
  • PCMag Review (Rating: 4/5): The reviewer liked the easy setup and how it quickly finds any file or email, even across Gmail, Yahoo Mail, SharePoint, and Box. The price tag and the extra yearly fee for premium support raised some hesitation, but the search experience felt far more sophisticated than Windows Search.
