Where Effy is strong
Effy started as a 360-degree feedback tool and grew into AI review writing from there. The 360 feedback capability is a genuine differentiator — if your performance-review process includes collecting peer / direct-report / cross- functional feedback before the formal review, Effy has built-in tooling for that and Crestento doesn’t.
Effy is also more established. It’s been around longer, has more customers, more case studies, more public reviews on G2 / Capterra. For an HR buyer who needs to demonstrate due diligence on tool selection, Effy has the maturity advantage.
Where Crestento is better
Three structural differences.
Role calibration is much deeper.Crestento ships with 74 individually tuned role recipes. Each recipe is hand-written and covers: the specific competencies that matter for that role, the vocabulary practitioners use, the kinds of metrics that count as evidence, the work artifacts that signal real engagement, and the stock filler that should never appear. A software engineer review reads as one. A sales rep review reads as one. A nurse review reads as one. Effy’s role-specificity is more template-driven and less language-aware.
Fact verification is built in.Every Crestento draft goes through a second AI pass that checks the output against the manager’s input. Any specific fact (number, name, date, project) that isn’t grounded in what the manager wrote gets flagged and removed before the final draft is shown. This catches the single most common AI-review failure mode: invented metrics or customer names. Effy doesn’t have an equivalent.
Pricing favours the individual buyer. Crestento is $149/year for one manager. No per-employee scaling. No annual contract requirements. The free tier (2 lifetime drafts) lets a manager run the comparison themselves before paying anything. Effy’s pricing model is closer to per-employee monthly, which favours organisations buying for the whole team.
When Effy is the better choice
You need 360-degree feedback collection as part of your review cycle and you want it integrated with the review- writing tool. You’re buying for an HR team or organisation, not as an individual manager. You weight maturity / customer references heavily in your decision.
When Crestento is the better choice
You’re an individual manager or small team that wants the actual review drafts to read as role-specific and evidence-grounded. You don’t need 360 collection tooling (you have your own process, or your company runs the 360 elsewhere). You want a flat annual price, not a per-employee plan. You want a structural guarantee against invented specifics in the final draft.
Try them both
The honest answer for most managers is: run the same review evidence through both. Crestento’s free tier gives you two lifetime drafts; Effy has a free tier too. The role-specific output difference is usually obvious within one draft. If it’s not, the pricing comparison probably decides for you.
