Input
Your games
PGNs, URLs, and live games enter the same prep pipeline.
ChessLM
Real games to match-day planMatch-day preparation room
ChessLM
Turn real games into a match-day plan you can trust.
Import your own games, clean the corpus, model the opponent, validate one practical novelty, rehearse the critical positions, and leave with a pack you can review before the round.
Local analysis by default. AI coaching stays behind first-party server boundaries.

Output
Pack
The end state is an exportable match-day artifact.
Preparation chain
One arc from source games to round-ready decisions.
The experience should feel like an evidence desk: every action moves the player closer to a concrete match-day pack.
01
Import real games
Bring PGNs, public game URLs, or live games into one local-first corpus.
Source material
02
Model the opponent
Expose repertoire branches, move-order tendencies, and corpus confidence.
Opponent map
03
Validate novelty
Rank candidate deviations by surprise, practicality, and eval tolerance.
Prepared choice

Rehearse critical moments
Convert swing positions into drills and readiness checks.
Execution reps
05
Export the pack
Assemble focus lines, directives, checklist, and provenance into one portable artifact.
Match-day pack
Product surface
Board first, evidence always visible.
ChessLM should feel like a tournament scoresheet merged with an engine lab: compact, legible, and built around decisions instead of decoration.
Prep mission timeline
Corpus, model, novelty, critical moments, drills, readiness, and pack stay visible as the working loop.
Trust-coded analysis
Analysis depth, engine disagreement, and reliability warnings use explicit labels plus semantic color.
Grounded coach
Text and voice coaching must cite the current board, corpus, or prep artifact rather than free-floating advice.
3D board surface
React Three Fiber keeps the premium board native to the workspace without a separate game runtime.
Capture gate
Marketing proof requires provenance.
The launch page should show product media only after the capture is tied to a real workflow, redacted, and approved. Until then, the page uses a data-neutral product composition instead of demo screenshots.
Demo-only captures are deliberately excluded from this page. Add approved, redacted production captures before any award or launch review.
Real workflow source
Capture corpus quality, novelty validation, readiness, pack export, and coach grounding from production flows.
Private data redaction
Account IDs, prompts, transcripts, tokens, and private game data must be removed before publishing.
No demo proof
Development preview data can exist inside the app, but cannot be used as judged marketing proof.
Release bar
Security and degraded states are part of the design.
Award-level polish fails if storage, auth, engine, payment, or provider boundaries degrade silently.
Server-side secrets only
Provider calls stay behind first-party server or worker routes. No keys ship in browser bundles.
Explicit degraded UX
Storage, auth, engine, API, and payment failures must surface visible states with machine-classifiable codes.
3D board is gated by QA
Canvas health, board readability, responsive layout, auth, payment, and build gates decide launch readiness.
