Keystone Codex In development
Answers you can put your name on.
Built for regulated work, where every answer must match the source and stand up to review.
Start a conversationFor work where a confident wrong answer is worse than no answer.
Keystone Codex works from authorized public or licensed reference sources. Access controls are enforced before retrieval, every statement cites its source, conflicts stay visible, and unsupported questions get no answer. Every exchange lands in a tamper-evident audit log.
Eight rules it does not break. Grounded, cited, permissioned, logged.
-
01
Grounded, not generative guessing
Every answer comes from authorized reference sources. If the evidence does not support it, the system abstains and explains why.
-
02
A citation on every claim
Each statement links to the exact source passage, turning verification into a quick check.
-
03
Conflicts surfaced, not smoothed over
When two sources disagree, you see both, side by side.
-
04
Your access rules, enforced first
Access controls are applied before retrieval. No answer can expose source material outside the user's permission scope.
-
05
A full audit trail
Every question, answer, and source is recorded in an append-only audit log.
-
06
Regulations that move are watched
Federal sources are monitored, and stale material is flagged before it can be served as current.
-
07
Measured, not assumed
Each change runs against adversarial tests. Wrong answers and unnecessary refusals are tracked separately.
-
08
Works where you work
Supports single sign-on and an offline mode for field environments without internet access.
It says "I don't know" instead of guessing.
Tuned to your field
The same engine, your rules.
Industry configurations adapt the same engine to your terminology, workflows, and governing rules. If your team answers to a regulation, manual, or policy, tell me about it.
