Top picks

Glean

Work AI platform for enterprise search, assistants, and agents

Toolglade's take: Glean is one of the strongest enterprise Work AI platforms available, but it is a serious, sales-led enterprise purchase with 100-seat-class minimums, not a tool a small team casually adopts.

Hebbia

AI built for the rigor of finance, law, and enterprise research

One of the most credible enterprise-grade AI research tools for finance and law, but it is a top-down, contact-sales platform with no self-serve tier, so it only makes sense for firms with real document-heavy workloads and budgets.

Dust

Build and deploy AI agents on your company knowledge

Dust is one of the more mature enterprise agent platforms, with strong data connectors, governance, and real adoption. The main thing to watch is cost predictability: its 2026 move to credit-based pricing means spend scales with model and tool usage, so heavy agents can get expensive. It is best suited to teams that want shared, governed agents on company data rather than individuals looking for a personal assistant.
