Karven vs Sammy.
Where each tool wins.
Sammy is the closest tool to Karven: an AU/NZ AI estimator that turns a voice note, photo or plan into a priced quote. The difference is where the number comes from. Sammy learns your pricing from your past quotes, so the estimate is an AI guess trained on your history. Karven prices from a deterministic per-trade engine and shows the customer every line, so you can stand behind it.
- Sammy: $99 / mo (1 user), $249 / mo (3 users)
- Sammy model: per-user
- Karven: $59/mo per workspace

§02 / Where Karven wins
What Karven does that Sammydoesn't.
Deterministic engine, not a learned guess: cut-lists, frame brackets and supplier rates produce the price and every line is shown and yours to approve (Sammy's number is an AI estimate trained on your past quotes, so it inherits and drifts on your old mistakes)
Show-the-maths on the customer's quote so they see the working behind the price (Sammy outputs a proposal, but the pricing logic is a black box)
$59 / mo per workspace, add your apprentice free (Sammy is $99 for one user, $249 for three)
The same engine is an embeddable estimator on your own website plus SEO microsites: a lead front-door, not just a quoting tool

§04 / Verdict
“If you want a tool that mimics your past quotes, Sammy. If you want a tool that prices from a real engine and shows your customer every number so you can defend the quote, Karven. We think the tradie who shows the maths wins the trust, and the job.”
