## 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

## Serif

Serif builds AI agents that take over the repetitive but fiddly parts of running a business: collecting documents, answering routine questions, chasing paperwork, and keeping follow-ups on track. You point the platform at real work, it learns how your team handles it, and then it runs the task continuously. When an agent encounters something outside its instructions — an unusual request, a missing document, an ambiguous clause — it routes the job to the right person rather than guessing. The result is automation that reaches completion instead of stalling halfway through a multi-step process.

The platform organizes this around three stages: diagnose, train, and run. Diagnosis surfaces workflows worth automating, training teaches agents how your business operates, and running puts the work on autopilot. Typical deployments cover document collection and processing (requesting, reading, and verifying files until a job is complete), compliance intake and quoting, complex support, accounting and tax tasks, real estate closing files, law firm engagement letters and questionnaires, and insurance claims packet collection. Agents work 24/7 across email threads, shared inboxes, and document attachments.

Security is treated as a first-class requirement. Serif states that your email is never used to train models and never stored on its servers, that everything the platform learns is encrypted at rest, and that its practices are audited by a third party. It publishes SOC 2 Type II, CASA Tier 2, HIPAA, and GDPR compliance claims. The product also offers a standalone personal email assistant and a free inbox report as an entry point, with paid plans for teams that need shared inboxes and full automation.

**Pricing & Plans:** Paid subscription with a free starting point. Serif offers a free inbox report and a downloadable personal email assistant, while shared inbox and full agent automation capabilities are sold on paid plans. Specific tiers and per-seat pricing are shown on request or at signup.

- **Email & Document Workflows:** Agents read email threads, pull attachments, run lookups, apply your policies, and write replies automatically, covering tasks from routine answers to multi-step document chasing.
- **Document Collection & Processing:** Serif requests paperwork, reads what comes back, checks it against what you actually need, and keeps following up until the file is complete — ideal for closings, claims, and intake packets.
- **Human-in-the-Loop Escalation:** When an agent is unsure how to proceed, it routes the job to the right person for review, so automation handles volume while judgment stays with your team.
- **Shared Inbox & Team Tools:** Manage addresses like info@, support@, billing@, and closing@ from a shared inbox, with email management, autoresponders, and customer service agents built in.
- **Enterprise-Grade Security:** Email is never used to train models or stored on Serif's servers, learning is encrypted at rest, and the platform meets SOC 2 Type II, CASA Tier 2, HIPAA, and GDPR standards.

**Strengths:** Handles full multi-step email and document workflows, not just drafting replies; Transparent security posture: no model training on your email and no email stored on its servers; Escalation keeps human judgment in the loop for ambiguous cases; Covers a wide set of industries including legal, insurance, real estate, and accounting

**Limitations:** Specific pricing tiers are not published on the homepage and require contacting sales or signing up; Best value requires committing to the platform's workflow model and training agents on your processes; Automation depth depends on how well you define and document your own rules
