Where TangentFlow sits

Measurement plus the fixes, priced for one business.

Free scan on ChatGPT with no account. Pro at $29 a month covers one business on all four assistants with weekly re-checks, unlimited drafts, Autopilot articles, proof pages, custom questions, CSV and MCP. Agency at $199 covers eight businesses with white-label reports. The trade-off: we cover four assistants, not ten, and we do not sell real-user prompt volumes.

Questions people ask

Which one should a small business pick?+

If you want to watch a fixed set of prompts, Otterly is the cheapest serious option. If you want the fixes written and published as well as measured, TangentFlow or Surfeo. Enterprises with a dedicated team look at Profound, Peec or Athena.

Are these prices current?+

They were read from each vendor's public pricing page on 6 September 2026 and will drift. Treat them as a starting point.

Why list competitors on your own site?+

Because assistants answer “TangentFlow alternatives” from somewhere, and we would rather it be a fair page than a guess.
