Glean alternatives: choose around the knowledge problem you have.

Start with the job, not the shortlist

An alternatives search can make unlike products look interchangeable. Before comparing vendors, write down the problem in plain language. Is your team unable to find existing information? Is the information out of date? Or does it live in someone’s head and need to be captured first?

Glean describes an enterprise AI platform that connects company sources, maps context, and supports search and agents. That is a useful baseline, but your evaluation should reflect the work you need done.

Guru: evaluate knowledge ownership and verification

Guru documents designated verifiers, verification states, and automated quality checks through Knowledge Agents. It also offers search across connected sources.

Consider it when your main challenge is agreeing who maintains answers. In a demo, ask the person who would own that work to update a policy, change its review state, and explain how an employee can see whether it is current.

Notion: evaluate a shared place to write and maintain knowledge

Notion’s wikis support page owners and verification. That gives teams a way to organise authored knowledge and make maintenance responsibilities visible.

Consider this route if the priority is building a writing habit around a shared handbook. Ask who will create the content, how they will know it needs an update, and whether the team will return to it during daily work. A well-designed workspace still needs someone to supply the experience it should contain.

Sirca: evaluate company context and expertise capture

Sirca combines connected company information with Knowledge Interviews. Employees answer focused questions, approve their words, and contribute knowledge that authorised colleagues and connected AI tools can use.

It is worth evaluating when the gaps are partly undocumented experience: handovers, decision rules, account history, and process exceptions. Confirm your required connectors, permissions, and usage limits. Do not assume a smaller shortlist means every product has equivalent source coverage.

Use the same test for every vendor

Choose five real questions and gather the evidence a correct answer would need. Include a straightforward lookup, a question spanning two sources, outdated guidance, restricted information, and something currently known only by an employee.

Let the intended users judge the results. Record how long it takes to find a usable answer, whether the source is clear, and what still requires manual effort. Ask for full commercial terms including implementation, seats, usage, support, and renewal. Avoid deciding on an impressive demonstration alone.

• Can the team inspect the source behind the answer?
• What happens when two sources disagree?
• Can someone without permission retrieve restricted information?
• Who keeps content current after the initial setup?
• How will knowledge that has never been written down enter the system?
