Pros & Cons

ChatGPT

Pros

  • Covers chat, deep research, image generation, voice and coding in a single subscription.
  • Has a wide price range, from an $8 Go plan to Business seats at $20 per user on annual billing.
  • Business data is not used for training, and Business includes SAML SSO and MFA.
  • Standard and Premium seats can be mixed so heavy users get more capacity without upgrading everyone.
  • Pro tiers bundle monthly API credits that developers can use.

Cons

  • Usage caps vary by plan, change often, and are a frequent complaint from heavy users.
  • Users report confident hallucinations and context loss in long threads.
  • SCIM, role-based access and data residency require Enterprise through sales.
  • Plus and individual plans have no annual billing discount.
  • API usage is billed separately from all ChatGPT subscriptions.

Glean

Pros

  • Glean lists more than 275 connected apps, so employees can search Slack, Drive, Jira, Salesforce and other tools from one place.
  • Search results follow each source system's access controls, which lowers the risk of exposing data to the wrong people.
  • AI answers include citations that link back to the source documents, so users can check them.
  • Developers get Client and Indexing APIs, a Web SDK, agent toolkits and an MCP server for building on Glean.
  • Its compliance certifications include SOC 2 Type II, ISO 27001, ISO 42001 and HIPAA.

Cons

  • Glean publishes no prices; third-party reports put seats at about 50 dollars or more per user per month with minimums of roughly 100 seats.
  • There is no free trial, and some reports describe proofs of concept as paid.
  • Setup, permission configuration and relevance tuning take significant work from IT teams.
  • Reviewers report renewal increases of about 3 to 12 percent a year and possible extra fees for premium support.
  • Some users report answers that do not fully match the source data, and say the ranking is hard to customize.
