Datasheet

Jalaran Datasheet answers questions about a component datasheet and cites the exact page the answer came from — a page number it verified rather than one it invented.

Who Datasheet is for

For hardware engineers and makers hunting one number through a 200-page datasheet. The page citation is the whole point: an answer about a maximum rating that you cannot check is an answer you cannot use.

What Datasheet does

Datasheet retrieves from your own component PDFs and answers only from what the document contains. The design detail that matters is that chunks never span a page boundary, so every citation points at a real page — and any page number the model produces that does not check out is dropped rather than displayed. This is what separates it from Lens, which joins every page into one string before chunking and can therefore cite a document but never a page. On a datasheet, the page is the answer.

  • Page-level citations, verified rather than invented
  • Local retrieval over your own PDFs
  • Multi-datasheet library
  • Answers grounded in the document only

How Datasheet works

  1. Upload the datasheet

    Your own component PDFs, building a library you can query later.

  2. Ask a specific question

    Absolute maximum ratings, pin functions, timing, thermal limits — the things buried deep in the document.

  3. Read the answer with its page

    Grounded in the document only, with a page citation attached.

  4. Verify on the page

    Go straight there. The citation exists so you can check, and on a rating you are designing around you should.

What Datasheet does not do

Datasheet needs PDFs with a real text layer — there is no OCR, so a scanned datasheet cannot be read, which rules out a lot of older components. It answers from the document and will not tell you what is not in there, and it cannot read a schematic, a diagram or a pin-out drawing that exists only as an image. Always verify a rating you are designing around on the cited page.

Common questions

How is this different from Lens?

Lens joins a document’s pages into one string before chunking, so it can cite a document but never a page. Datasheet keeps chunks inside page boundaries so a citation points at a real page — which on a 200-page datasheet is the difference between useful and useless.

Can it read diagrams and pin-outs?

No. It retrieves text. A pin-out that exists only as a drawing cannot be read, and a scanned datasheet with no text layer cannot be used at all.

Can I trust the page number?

The citation is verified against the document, and a page number that does not check out is dropped rather than shown. That said, go and look — on an absolute maximum rating, checking is cheap.
