Tettra
Pros
- + Kai answered test questions with links to exact source pages and admitted gaps instead of improvising
- + Stale pages, unowned content and verification workflows actually route maintenance work to named owners
- + Unanswered Slack questions become documented answers over time — the knowledge base improves with use
- + $8/user/month billed yearly with unlimited storage and unlimited version history is fair value
- + Publishes concrete reliability signals: 99.99% claimed uptime, public status page, PCI Level 1 payment processor
Cons
- - No free plan; 10-user minimum on Scaling makes small teams pay for seats they do not have
- - Authoring is plain versus Notion or Confluence — limited formatting and block types
- - SSO and SCIM are paid add-ons on Scaling; group permissions require the SCIM add-on
- - Export is HTML only, which complicates any future migration
- - Acquired by GSoft/Workleap in 2023 and the pricing page's FAQ still references old plan names — expect some roadmap and documentation drift
GPT for Sheets and Docs
Pros
- + Cell-level functions (GPT, GPT_TRANSLATE, GPT_EXTRACT, GPT_CLASSIFY) process thousands of rows independently, and in my 500-row test a deliberately exhausted credit balance reported the run as interrupted while preserving per-row success/failure counts
- + Pay-as-you-go to subscription economics with $25/month Standard including $25 of usage and shared extra-usage pools on Business at $45/seat — no per-seat AI lock-in for spiky agency workloads
- + Enterprise plumbing is real: ISO 27001 certification, SAML SSO on Enterprise, BYOK/custom endpoints, zero-data-retention options and a stated no-training policy (vendor documentation)
- + Model breadth across OpenAI, Anthropic, Google and others, with Autosheet MCP (shipped August 2026) letting Claude or ChatGPT drive the spreadsheet agent from an external client
- + Detailed usage reporting maps credit spend to tokens and requests, so I could price each bulk column before committing to a run
Cons
- - No permanent free tier: the trial credits run on a single model, so the multi-model selling point cannot be evaluated without subscribing ($25/month at time of writing)
- - Docs usage billing is not explained on the pricing page, which covers Sheets and Excel plans only
- - The mid-2026 rebrand to Autosheet means listing names, website and docs disagree for now — a mild tracking burden for buyers
- - Multi-account Google sign-ins trigger documented authorization errors; Workspace admins must allow add-on execution
- - The sidebar agent writes formulas but does not reason about cross-sheet business logic — tasks execute, outcomes are still yours to verify
