Run this example, then replace the text and question with your own.
Your text and question are sent through this site's server to its configured Jev provider when you search. Omit secrets and private material.
These options change the next Jev request. Edit them before searching again.
The whole text can supply the answer across several passages. Changes the next Jev request.
Short text can remain one passage. To preserve every character, actual sizes vary at boundaries and when ten passages must be merged.
3 contiguous original passages; the complete request State fits 8,000 characters. No text is omitted.
Cancellation policy Customers may end a monthly plan at any time. Access continues until the current billing period ends.
Payments and credits A credit for unused days is issued to the original payment method within five business days after cancellation.
Contact For a copy of an invoice, write to the billing team.

Between the two thresholds: Uncertain. These are this site's display rules, not TypeSafe-recommended cutoffs.
Read each passage in place. Line numbers refer to the text you pasted.

Choice distributes probability across this request's candidate passages. The leading passage is relative to this particular set, not an independent relevance score or a guarantee that it answers the question. Scores from different sets cannot be compared as absolute relevance.
Boolean/Noul provides P(exists) for the submitted material. The three visible states are this site's review policy; an uncertain value is not a claim that the text partially answers the question. A low value says nothing about information outside this text.
Provider confidence is shown separately when available. Low confidence suggests reading several candidates. Missing confidence is labeled Not provided, never replaced by the top Choice probability.
The official line-by-line search cookbook tags source clauses, then uses Choice and Noul in one request. The jev-mcp jev_find tool lets an agent rank caller-supplied candidates. jgrep gathers local code or diff hunks, chunks them, and asks per-chunk Noul questions before returning file-line ranges. This page only searches text you paste; it does not scan a repository, use an MCP server, or call an internet search provider.
There is no vector index here. That does not prove Jev search is generally better than embeddings; for known exact words, ordinary text find remains useful. For a separate evidence-oriented task, try the Citation Verifier.
Search only examines the text you paste. Read the original passages before treating a lead as an answer.
This browser tool accepts one pasted text, one question, and an optional answer requirement. It does not read local files, fetch URLs, store a knowledge base, generate an answer paragraph, or assert that the first passage contains every needed fact. The source label is supplied by you; pasted line numbers are not verified file or web-page coordinates. Frozen A/B results live only in this page's memory; reload clears them. No input or result is placed in a shareable URL or account.
Your text, query, and answer requirement travel through this site's server to its configured TypeSafe Direct or Vercel Gateway provider when you submit. Omit secrets and unrelated private text. Provider-path data handling varies; do not assume text stays in the browser or that every request has ZDR. See how to use Jev and the API guide. The Choice/Noul pattern follows TypeSafe's Choice, Noul, and confidence contracts. Splitting options, answer requirements, A/B comparison, and display cutoffs are this site's design, not official recommended settings.
On September 24, 2026, the same six synthetic cases were run once through TypeSafe Direct and once through Vercel Gateway. Against criteria set before the runs, Direct met 4 of 6 and Gateway met 5 of 6. In the cases that missed those criteria, Jev still pointed to relevant original text, but its answer-present signal remained uncertain. This small check is not an accuracy benchmark or a guarantee for other text. Material can contain an answer while Jev remains uncertain, and the first-ranked passage may not contain every needed detail.
