Glean vs Sunsama

Glean is an enterprise work AI platform that indexes a company's apps, documents and conversations and lets employees search, ask questions and run agents over that knowledge. It was founded in 2019 in Palo Alto by former Google search engineer Arvind Jain, who previously co-founded Rubrik, and it raised a $150 million Series F at a $7.2 billion valuation in June 2025.

The platform has three layers: Glean Search, a ranked enterprise search; Glean Assistant, a chat assistant grounded in company data; and Glean Agents, which automate multi-step work from natural-language instructions. Underneath sit 275+ connectors, an Enterprise Graph that maps people, content and activity, and permission enforcement that mirrors each source system in near real time. It also offers APIs and MCP support. Pricing is not published; it is sold per seat through sales, with demos instead of a self-serve trial.

Glean fits large organizations with knowledge scattered across Slack, Google Drive, Confluence, Jira, Salesforce and code hosts. It is overkill and likely too costly for small companies, and results depend on clean permissions in source systems. Microsoft 365 Copilot is the natural rival for Microsoft-centric firms, ChatGPT Enterprise offers broader general AI with connectors, and Notion AI covers search well if Notion is already your wiki.

Glean announced in December 2025 that its annual recurring revenue had passed $200 million, doubling in nine months. When evaluating, run a pilot on your messiest knowledge sources and test permission boundaries with a few restricted documents.

Sunsama is a daily planner for professionals who juggle tasks across many tools. It is built around a guided ritual: each morning you review your calendar, pull tasks from Asana, Trello, Linear, Jira, Notion, ClickUp, Todoist, GitHub, Gmail, Outlook and Slack into today's list, estimate how long each will take and drag them onto your calendar as timeboxes.

As you plan, Sunsama totals your estimated time and warns when you have taken on more than fits in your working hours, which is the core of its approach to sustainable work. Focus mode shows a single task with a timer, a daily shutdown ritual reviews what got done and what moves to tomorrow, and weekly planning and reviews connect daily work to bigger objectives. Calendar sync works with Google, Outlook and iCloud. There is a single paid plan, billed monthly or at a discount annually, with a free trial but no free plan.

Sunsama fits knowledge workers, managers and freelancers who want calm, intentional days and a single view of work scattered across tools. Planning takes a few minutes each day by design, it is not a team project management tool and the price is high for a personal app. Motion automates scheduling with AI instead of manual planning, Akiflow offers a similar task inbox with time blocking, and TickTick is a cheaper all-round planner.
