## 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

## Instafill.ai

Instafill.ai tackles one of the most tedious parts of paperwork: filling out the same PDF and Word forms over and over. You upload a flat PDF or a .docx template, and the platform's LLM-based extraction engine detects the fields, groups related inputs intelligently, and pulls answers from source documents, emails, or saved profiles. The result is returned in roughly 25 to 60 seconds per form, with a visual editor for reviewing and correcting values before export.

The platform stresses explainability and control. Every filled field can show its source and reasoning, style-replication learns from your corrections so future forms match your formatting, and version-aware prefilling extracts values from an older copy of a form to populate a new one. Large batches are handled with concurrent field processing, and tables and repeating row structures get dedicated structured-data handling.

Security is positioned for regulated industries: field-level AES encryption at rest, multi-provider authenticated login with optional two-factor authentication, complete multi-tenant workspace isolation, and a choice of data residency region. Instafill also ships developer-facing tooling, including a REST API, an MCP server for Claude and ChatGPT, and native n8n and Zapier integrations.

**Pricing & Plans:** Instafill.ai offers a free entry point (sign-up to try), paid subscription tiers, and enterprise plans that require contacting sales. Specific per-plan rates are not published on the homepage, so check the pricing page for current figures.

- **LLM-based field extraction:** Automatically detects and maps every field in a flat PDF or Word form, using semantic understanding rather than rigid templates.
- **Explainable fill results:** Each filled field can display its source and the reasoning behind the value, making verification fast and auditable.
- **Batch and table processing:** Runs concurrent parallel field filling and handles structured row data, so multi-form packets and repeating tables are completed together.
- **Claude and ChatGPT MCP integration:** An MCP server lets you fill PDFs from inside Claude Desktop, Code, or ChatGPT, plus n8n and Zapier automations for wider workflows.
- **Security and data residency:** Field-level AES encryption at rest, optional two-factor authentication, workspace isolation, and a choice of data residency region.

**Strengths:** Works on flat documents, not just already-fillable PDFs; Reports explainable field-level sources for easy review; Batch mode and table handling suit high-volume paperwork; MCP server plus n8n and Zapier integrations fit existing automations

**Limitations:** Detailed per-tier pricing is not shown on the landing page; Accuracy still benefits from human review on complex or ambiguous forms; No native mobile app experience is highlighted; Advanced workflow features target teams rather than casual single-form users
