What to know before choosing

Good fit

Independent strategy consultants who need to defend a recommendation against the full project record, not one document.; Consultants whose client evidence conflicts, for example management blaming pricing while the strongest signal is onboarding friction.; Teams that want every conclusion traceable to an original passage, with isolated contexts per project.

Limits and trade-offs

Consultants who need more than one active project and more than 20 sources on the free tier, since those limits belong to the Founder's Pass.; Users who want Messync to train public AI models on their project, since the pricing page states project content is never used to train public AI models and the user decides which sources enter.; Teams that need unlimited projects and expanded source limits without paying, since those are Founder's Pass features.

Plans and free allowances

Free at 0 euros with 1 active project, up to 20 sources and limited research queries; Founder's Pass at 39 euros per month with unlimited projects and expanded limits. Early customers keep the Founder's Pass price while their subscription stays active.

A closer look at Messync

Messync turns a messy client project into conclusions a consultant can defend: it cross-examines decks, spreadsheets, interviews and notes across the entire project, surfaces where explanations conflict with what customers say and what the numbers show, and gives interactive citations to the original passage.

Editorial guidance based on published documentation. The workflow below is a suggested starting point, not a measured product result.

When to choose Messync

  • Independent strategy consultants who need to defend a recommendation against the full project record, not one document.
  • Consultants whose client evidence conflicts, for example management blaming pricing while the strongest signal is onboarding friction.
  • Teams that want every conclusion traceable to an original passage, with isolated contexts per project.

When to choose something else

  • Consultants who need more than one active project and more than 20 sources on the free tier, since those limits belong to the Founder's Pass.
  • Users who want Messync to train public AI models on their project, since the pricing page states project content is never used to train public AI models and the user decides which sources enter.
  • Teams that need unlimited projects and expanded source limits without paying, since those are Founder's Pass features.

A practical starting workflow

  1. Start with a real project and add its decks, spreadsheets, interviews and notes.
  2. Ask where explanations conflict with customer voices and numbers, and follow the interactive citations to the original passage.
  3. Move to the Founder's Pass when the work needs unlimited projects and expanded limits.

Check before committing

  • The free plan is for trying the full flow on one real case, so it is a trial of the workflow, not a full client-work allowance.
  • Early customers keep the Founder's Pass price while their subscription stays active, so the stated price is tied to continuous subscription.
