AI Tool Profile
Comparator
A proof-versus-challenge checker now integrated into Lean core.
Before you buy
Best for: Proof authors maintaining an older pinned validation setup and planning migration to core Lean tools.
Price: Canada/CAD: C$0 Apache-2.0 code; local compute and dependencies separate
Included: For new setups, the repository recommends lake comparator and lake check in Lean 4.35.0 or later.
Main limits: The standalone repository is deprecated; only integrated tools are promised future security and performance improvements. A valid proof must still match the intended statement.
What Kingy showed: The October 6 pinned standalone pilot accepted one target twice, left two targets unresolved at its memory cap and recorded twenty-one expected control outcomes.

Which plan is worth considering
Canada/CAD: C$0 Apache-2.0 code; local compute and dependencies separate. For new setups, the repository recommends lake comparator and lake check in Lean 4.35.0 or later.
Limits that affect the purchase
The standalone repository is deprecated; only integrated tools are promised future security and performance improvements. A valid proof must still match the intended statement. The historical local pilot used no paid service. Setup, hardware and maintenance were not economically free. The tested setup used landrun and lean4export, with documented toolchain changes. It did not test the newer integrated commands.
What the existing demonstration shows
The October 6 pinned standalone pilot accepted one target twice, left two targets unresolved at its memory cap and recorded twenty-one expected control outcomes. Do not buy hardware from one target’s short runtime or interpret an out-of-memory stop as proof rejection. This describes the dated retained Kingy record, not a new product test. See the retained Kingy demonstration.
Sources and buying-review date
Buying details checked October 22, 2026. Plan research uses current official sources; demonstration descriptions use the retained Kingy record and any captured creator chapters. No new subscription, paid generation or checkout was performed. The buying-review date does not renew every claim in the broader facts ledger.
