Glean vs Perplexity AI

Glean connects your company's apps, documents, and permissions into one enterprise search and Work AI platform. Employees ask questions in natural language, get answers grounded in Slack, Google Drive, Jira, Confluence, Salesforce, and hundreds of other sources, then automate follow-up work with assistants and agents. The system respects existing access controls so people only see what they are already allowed to view.

Generic AI chat tools send broad prompts to models without your org chart, ticket history, or doc permissions baked in. Glean indexes enterprise context once, maps relationships in an Enterprise Graph, and claims a 30% reduction in token usage compared with off-the-shelf MCP tools because less irrelevant text reaches the model. That matters when every department is spinning up agents on the same data.

IT, engineering, sales, support, and HR teams at companies like Booking.com, Zillow, and Samsung use Glean to find answers faster, build no-code agents, and cut internal support tickets. Deployment is demo-led: you request access through Glean's sales flow rather than self-serve signup.

Perplexity AI answers questions by searching the live web and citing the sources it used. Ask in plain language and you get a synthesized reply with inline links to pages, reports, and data feeds rather than a chatbot guess. The free tier covers everyday search; paid plans add deep research, premium data sources, and access to multiple frontier models.

Where ChatGPT and Claude answer from memory, Perplexity treats every query like a research brief: it pulls fresh pages, shows which source backed each claim, and lets you pick between models like Sonar 2, GPT-5.6 Terra, Gemini 3.1 Pro, and Claude Sonnet 5 for different tasks. The newer Computer feature goes further, handing off multi-step projects so Perplexity can build documents, apps, and polished deliverables on a schedule.

Analysts, students, and operators in finance, legal, and tech use it for earnings breakdowns, competitor scans, and cited briefs they can share with a team. Connectors link Gmail, Google Drive, Slack, GitHub, and dozens of other services so answers can draw on your own files and messages, not just the public web.
