How it works
1 · Score
The extractive engine splits your context into sentences and scores each by information density, with primacy/recency weighting — because models forget the middle (Lost in the Middle, TACL 2023).
2 · Forge
Top sentences fill your token budget in original order. First and last sentences are always kept. Numbers, dates and URLs get extra protection.
3 · Verify
Every checkable fact in the original is matched against the output. Anything missing is flagged by severity before you ship the prompt.
