Describe what you need, paste a small text, and read the original passages Jev points to. A separate existence check helps you see when the submitted material may not answer the question at all.
The workbench creates up to ten contiguous candidates from your text, preserving every character and each passage's position. You can edit all inputs before one explicit request.
Try a synthetic text
Each example fills editable fields. Selection never sends a request.
01 / YOUR TEXT Editable · original retained
3 contiguous original passages; the complete request State fits 8,000 characters. No text is omitted.
On submit, your question, source label, and full text pass through this site's server to its configured TypeSafe Direct or Vercel Gateway provider. Omit secrets and private material.
One explicit browser request: two questions for multiple passages, or one existence question for a single passage. Provider failover may make another underlying attempt.
02 / READING LEADS No generated answer
⌕
Find the original passage
Search returns places to read, plus a separate judgment about whether this text contains an answer. It never writes an answer for you.
03 / ORIGINAL TEXT
Read it in place
Line numbers refer only to this pasted text. Every passage is an exact slice of your input; repeated text keeps its own position. Long lines scroll inside this panel.
p1 · pasted lines 1–3
Cancellation policy
Customers may end a monthly plan at any time. Access continues until the current billing period ends.
p2 · pasted lines 4–6
Payments and credits
A credit for unused days is issued to the original payment method within five business days after cancellation.
p3 · pasted lines 7–8
Contact
For a copy of an invoice, write to the billing team.
02 / INTERPRET THE SIGNALS
A ranking is not an answer
CHOICE · MULTIPLE PASSAGES
Where to read first
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.
NOUL · EVERY REQUEST
Does this text address it?
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.
CONFIDENCE · CHOICE ONLY
How concentrated is the choice?
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.
03 / REAL IMPLEMENTATIONS
Three scopes, three different tools
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.
04 / LIMITS & SOURCES
Know what was and was not searched
This browser tool accepts one pasted text and one question. 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. No input or result is placed in a shareable URL or persisted as a user account.
Your text and query 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 design follows TypeSafe's Choice, Noul, and confidence contracts. This new scenario has not received real-model semantic validation here.
