Glean vs Todoist

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.

Todoist is a task manager made by Doist, a fully remote company founded by Amir Salihefendić, who started Todoist as a side project in 2007. It is known for fast natural-language input, a clean design and apps on almost every platform, including web, Windows, macOS, Linux, iOS, Android, smartwatches and browser extensions.

Typing a phrase such as 'pay rent every 1st at 9am' creates a recurring task with the right date, and projects, sections, sub-tasks, labels, priorities and saved filters organize everything. Board and calendar layouts, two-way Google Calendar sync and task durations put work into time. Integrations connect Todoist with Gmail, Slack, Outlook and automation tools. The free Beginner plan covers five personal projects; Pro adds reminders, the calendar layout, many more projects and filters and an AI assistant that helps break tasks down; Business adds a shared team workspace with roles and templates. Doist also makes Twist, an asynchronous team messaging app.

Todoist suits individuals and small teams that want a reliable, cross-platform task list that stays out of the way. It is not a full project management tool, with no dependencies or resource planning, and the free plan's reminders and filters are limited. TickTick adds habits and a Pomodoro timer at a similar price, Things is a calm Apple-only alternative, and Asana or ClickUp fit teams that need full project management.
