| <p>Extract character-offset <code>[start, end]</code> spans, classify <code>boolean</code> & <code>enum</code> probabilities, verify cross-field algebraic invariants, abstain with calibrated <code>p_null</code>, and output <code>p10/median/p90</code> distributions with zero output tokens.</p> | |

| <h2>In Plain English · What does nullspan actually do?</h2> | |
| <span class="badge">Think of it as a Smart Highlighter + Calculator — Not a Chatbot</span> | |
| </div> | |
| <p class="plain-english-lead"> | |
| When you ask a standard LLM (like GPT or Claude) to pull structured data out of messy text, it writes JSON word-by-word—which is slow, costs money per output token, can get tricked by <em>"ignore previous instructions"</em> attacks, and often <strong>makes up fake answers (hallucinates)</strong> when a field is missing. <strong>nullspan</strong> reads your text once and extracts every field in a single pass without generating a single word: | |
| </p> | |
| <div class="plain-grid"> | |
| <div class="plain-item"> | |
| <strong>1. Points to Exact Text ([start, end] Span)</strong> | |
| <p>Instead of re-typing words, it highlights the exact character positions in your original text. Because it can only point to text that actually exists, it <strong>cannot hallucinate fake text</strong> or obey prompt injections.</p> | |
| </div> | |
| <div class="plain-item"> | |
| <strong>2. Knows When to Say "Not There" (p_null)</strong> | |
| <p>If an answer isn't in the text (like an unassigned CVE or missing discount), it calculates the probability that the field is missing (<code>p_null</code>) and cleanly returns <code>null</code> instead of guessing.</p> | |
| </div> | |
| <div class="plain-item"> | |
| <strong>3. Checks the Math Automatically (verified)</strong> | |
| <p>For numbers, dates, and invoices, it adds up line items, counts days between dates, and checks formulas like <code>subtotal == nodes * hourly_rate</code> so you know if the document's math is right.</p> | |
| </div> | |
| <div class="plain-item"> | |
| <strong>4. Gives Realistic Ranges (p10 / median / p90)</strong> | |
| <p>When you ask for an estimate or forecast (like tomorrow's server traffic or repair cost), instead of one shaky guess, it returns a low (<code>p10</code>), middle (<code>median</code>), and high (<code>p90</code>) range.</p> | |
| </div> | |
| </div> | |
| <div class="glossary-strip"> | |
| <span><strong>How to read the output badges:</strong></span> | |
| <span><code>span=[start, end]</code> Exact character slice in your input text</span> | |
| <span><code>p_null</code> Chance the field is missing (≥ 50% → returns <code>null</code>)</span> | |
| <span><code>verified=true</code> Cross-field math formula passed</span> | |
| <span><code>H=0.00b</code> Uncertainty in bits (closer to <code>0b</code> = more certain)</span> | |
