## Glean

Glean addresses a problem most enterprises hit after their first wave of AI adoption: models are powerful but isolated from the context of the business. The platform builds an enterprise context layer by indexing and understanding content across the tools a company already runs on, then uses that grounding to improve both answer quality and efficiency. Because fewer irrelevant tokens need to be sent to a model, the same question costs less to serve.

The product surface spans four areas: enterprise search, an AI assistant for everyday work, an agent platform for automating long-running processes, and Glean Protect for security and governance. Administrators also get model routing and an AI gateway, letting them decide which models handle which requests without rebuilding integrations. Everything inherits the access permissions of the source systems, so answers stay within each employee's existing rights.

Glean serves large organisations across finance, healthcare, retail, technology, and government, with published customers including Booking.com, Zillow, and Ericsson. It holds SOC 2 Type II, ISO 27001, ISO 42001, HIPAA, GDPR, and TX-RAMP Level 2 attestations, and reports 275+ connectors, 40+ supported language models, and 99.9%+ uptime on core services.

**Pricing & Plans:** Contact for pricing. Glean is licensed to organisations based on seats, connectors, and deployment scope, and is evaluated through a demo rather than self-serve purchase.

- **Permission-aware enterprise search:** Ask a question in plain language and get a cited answer assembled from documents, tickets, wikis, and messages across every connected system, with permissions respected.
- **Agent builder and orchestration:** Reusable agents handle multi-step workflows such as onboarding, account research, or incident follow-up by orchestrating actions across business apps.
- **Model routing and AI gateway:** Glean automatically picks and routes requests to the right model and reasoning level, giving teams access to 40+ LLMs through a single governed gateway.
- **Grounded content and analysis:** Draft on-brand documents, summarise meetings, analyse data, and create content grounded in company context rather than generic model knowledge.
- **Governance and observability:** Administrators get usage controls, spend visibility, audit logging, and compliance-ready governance for every AI interaction.

**Strengths:** Answers cite source systems and inherit their permissions, which removes the main blocker to enterprise-wide rollout; One platform covers search, assistant, and agents instead of three separate vendors; Model routing and token efficiency directly reduce the cost per AI query at scale; 275+ pre-built connectors shorten integration work considerably

**Limitations:** Enterprise pricing is quote-based, so budget planning requires a sales conversation; Full value depends on connecting many internal data sources, which takes IT effort; Smallest teams may find the platform more than they need

## Spamdrain

Spamdrain is an independent antispam service operated by Spamdrain AB, a company based in Gothenburg, Sweden. Rather than replacing your email provider, it attaches to the accounts you already use and screens incoming messages, so you keep your familiar address while gaining a filtering layer. The team says it has been refining its filtering technology since 2004, which shows in how quickly the system reacts to new spam campaigns.

Setup is intentionally simple: connect an email account, and Spamdrain starts judging new messages. Anything it accepts is passed through to your inbox, anything suspicious is held back, and occasionally you review the quarantine and confirm or override decisions. Those corrections train your personal filter, so results improve the longer you use it.

The service covers the platforms most people actually use, including iPhone, Android, Mac, Windows, Office 365 and general IMAP/POP mailboxes. It blocks spam, phishing links, malicious attachments and automated bulk mail, with a free 14-day trial so you can test it against your own inbox before paying.

**Pricing & Plans:** Free 14-day trial, then a low-cost paid subscription that Spamdrain describes as costing less than a cup of coffee. Exact plan prices are shown after sign-up or on the pricing page.

- **Multi-platform email coverage:** Works with iPhone, Android, Mac, PC, Office 365 and general IMAP/POP accounts, so one filter protects every device that reads the same mailbox.
- **Phishing, virus and spam blocking:** Every new message is analysed before delivery, and suspicious senders, malicious links and infected attachments are stopped instead of reaching you.
- **Adaptive personal filter:** Each time you mark something as spam or confirm it is legitimate, the filter learns your preferences and gets more accurate over time.
- **Reviewable quarantine:** Held messages are not lost. You can open your Spamdrain account, inspect what was blocked, and release false positives with a click.
- **Newsletter control:** Separate the newsletters you want from the bulk mail you never signed up for, so only the senders you care about get through.

**Strengths:** Simple setup: connect an account and filtering begins immediately; Covers iOS, Android, macOS, Windows, Office 365 and standard mail providers; Filter improves with your own corrections, not just global rules; Free 14-day trial lets you test on real mail before subscribing

**Limitations:** Pricing details are not fully published without going through sign-up; Quarantine still requires occasional manual review to avoid losing legitimate mail
