Shared context for AI tools
Glean vs BaseThread: enterprise search vs curated context
Glean vs BaseThread compared. Glean indexes everything and answers in its own UI. BaseThread distills the signal and feeds it to the AI tools you already use.
Glean and BaseThread get put side by side because both promise to make your company's knowledge useful to AI. They go about it in opposite ways. Glean indexes everything and gives you a place to search it. BaseThread distills the signal into a curated context layer and feeds it to the AI tools you already use. Once you see the difference, picking is easy.
What Glean does well
Be fair. Glean is a strong product for the buyer it targets.
- Search across every app. It connects to your whole tool sprawl and answers questions across all of it from one place.
- Passive coverage. You do not curate anything. It crawls, indexes, and connects on its own.
- Built for large orgs. Governance, scale, permissions, and an enterprise motion to match.
If you are a thousand-person company and the problem is "our knowledge is scattered across a hundred apps and nobody can find anything," Glean was built for exactly that.
Where Glean is a different shape than you might want
The same design choices that make Glean powerful for a large org make it a particular fit, not a universal one.
- It is a destination. Glean answers in Glean. People go there to search. It is not primarily about feeding your Claude Code, Cursor, or ChatGPT the context they need as they work.
- It indexes everything. A searchable copy of all your data is a different thing from a deliberate, curated context. More is not always better.
- It is an enterprise deployment. Six-to-twelve-week rollouts and enterprise pricing are a real commitment, aimed at IT, not a small team that just wants its AI tools aligned.
What BaseThread does instead
BaseThread starts from a different question: not "where can people search our knowledge" but "how do the AI tools we already use share our team's context."
- Curated, not scraped. It distills the signal from connected tools into a context graph, structured the way your company works (Company, Products, Teams, Projects, You), with three streams running through it: Activity, Decisions, and Tasks.
- Read by your existing tools. Claude Code, Cursor, ChatGPT, and any MCP client read that context over MCP, local or remote, so it shows up where you already work.
- Scoped, not firehose. Context is scoped to the right team or project, not a flat index of everything.
- The signal, not a dump. Integrations with tools like Notion and HubSpot distill what matters rather than copying everything wholesale.
The wedge is simple. Glean builds a searchable copy of everything in a box you query. BaseThread distills the signal into a curated graph and feeds it to the tools you already use. A curated layer your tools read, not a destination you go to.
Glean vs BaseThread
| Glean | BaseThread | |
|---|---|---|
| Core model | Index everything (search) | Distill the signal (curated graph) |
| Where you use it | Glean's own UI | Your existing AI tools, over MCP |
| Scope | Everything you query | The right team or project |
| Data shape | A searchable copy | A curated context layer |
| Captures decisions | No | Yes, an Activity, Decisions, and Tasks record |
| Setup | Enterprise deployment (weeks) | Connect a tool, read over MCP |
| Built for | Large enterprises | Teams that want their AI tools aligned |
Which should you pick?
- Large org that wants one search box over all its apps: Glean is built for that, and the ranked field of Glean alternatives covers the other search options.
- A team that wants its AI tools to share the same context without a separate search destination: that is BaseThread.
They are not really competing for the same minute of your day. One is a search surface. The other is the context your tools read before they answer.
The one-liner
Glean is where you go to search your company's knowledge. BaseThread is the curated context your AI tools already read, so the answer shows up in the tool you are using, not in a separate box.
TL;DR
Glean is enterprise search: it indexes everything across your apps and answers in its own UI, built for large orgs, deployed over weeks. BaseThread distills the signal from connected tools into a curated, scoped context graph and feeds it to the AI tools you already use over MCP, with an Activity, Decisions, and Tasks record. Glean is a destination you go to. BaseThread is a curated layer your tools read. Pick search if you want a box; pick BaseThread if you want your tools aligned.
Enterprise search vs curated context your AI tools read, side by side.

Frequently asked questions
What is the difference between Glean and BaseThread?
Glean is enterprise search: it indexes everything across your apps and answers questions in its own UI. BaseThread is a curated context layer: it distills the signal from your connected tools into a scoped context graph and feeds it to the AI tools you already use, like Claude Code and Cursor, over MCP. Glean is a place you go to search. BaseThread is context your existing tools read.
Is BaseThread a Glean alternative?
It solves a related problem from a different angle. If you want one searchable box over all your company's apps, Glean is built for that. If you want your AI tools to share your team's context without sending people to a separate search product, that is BaseThread. Some teams could even use both, Glean for company-wide search, BaseThread for the context that feeds their AI tools.
Does BaseThread index all my data like Glean does?
No, and that is the point. BaseThread does not build a searchable copy of everything you query in its own box. It distills the signal from connected tools into a curated graph, scoped to the right team or project, curated not scraped, and feeds that to your AI tools over MCP.
How long does each take to set up?
Glean is an enterprise deployment, commonly six to twelve weeks with IT involvement. BaseThread is in closed beta and built to be lighter: connect a tool, let it distill the signal, and your AI tools read the curated context over MCP. Request access to try it with your team.
