Ask the Ephemeris (concept preview)

The concept preview at ephemerisx.com/ask shows what asking the FDA and SEC Ephemeris will be like: how to ask, read an answer and open its sources.

Last updated October 7, 2026

The concept preview imagines a simple exchange: you ask a question about a company's FDA and SEC record, and the Ephemeris answers in the documents' own words, with every claim one click from its source.

Choose a company#

The ask overview: Deep research, a lead on what an ephemeris maps, and cards under Companies after an FDA Complete Response Letter · 10, including Achieve Life Sciences, Replimune and Aldeyra Therapeutics, each with the date of the FDA letter, its questions and a count of findings and source documents.
Figure 1. The overview (/ask/): ten companies after an FDA Complete Response Letter.

Each card shows the company, its ticker, the date of each FDA letter, the product, the questions you can ask, and a count of findings (quoted passages and searches) and source documents. Click Open →.

Every company page offers the same core questions, so companies can be compared: How does the company's 8-K compare with the FDA's letter?, Why did the FDA reject …? and What remains unresolved? Some add questions particular to their case.

Ask a question#

On a company page, the questions are listed under Ask about …, each with a one-line preview of its answer and its counts. The first opens on its own when the page loads.

  1. Click Ask beside a question.

  2. While the answer is prepared, the Ephemeris map works: the FDA's graph on the left, the SEC's on the right, arcs carrying evidence between them. The status line says what is happening, such as Reading 8-K · Jul 31, 2026 or Checking 8 findings against the source.

    A question being answered: the question box, and beneath it the Ephemeris map with FDA on the left and SEC on the right, joined by arcs, and the status Checking 8 findings against the source.
    Figure 2. The status line names each document as it is read, then the check.
  3. The answer arrives a few sentences at a time. Click Ask again to close it.

Questions you have already opened do not animate a second time. To link straight to a question, add ?q= and its position, counting from 0: /ask/replimune/?q=2 opens the third.

Read the answer#

The answer to How did the RP1 efficacy estimate change through the FDA review? A bold lead gives three response rates for three populations; four paragraphs quote the 8-Ks, the 10-K and the FDA's letter, each quote followed by a citation chip such as 8-K · Apr 13 or FDA · Apr 10 · p. 4. Below: 8 findings · 5 source documents and View reasoning. 1 2 3 4 5
Figure 3. An answer on Replimune's page.
  1. 1The question, with its Ask button.
  2. 2The lead. The answer in a sentence or two.
  3. 3Quotes and chips. Quoted words are the documents' own; the chip after each says where: 8-K · Apr 13, FDA · Apr 10 · p. 4. Click a chip to show the passage beside the reasoning graph.
  4. 4Counts. How many findings and source documents the answer uses.
  5. 5View reasoning → scrolls to the reasoning graph.

Notice what the answer does not do: it does not pick one response rate as the right one. The record holds three (34%, a confirmed 32.9% and 24.2%), for three different populations, and the answer says so. Reconciling them is the reader's call, with the passages in front of them.

Ask your own question#

The last box on each company page, Ask the FDA and SEC Ephemeris…, types out the kind of question the full product will take: any company, any question about the FDA and SEC record. In the preview, its Ask button leads to EphemerisX Pro.

Why it is built this way#

  • The answer shows its work while it arrives. The animation is not decoration: each status line names a real document the answer reads, and the last step is the check against the sources. An answer that cannot show where it came from should not be trusted, so this one shows it before you ask.
  • A small set of comparable questions. The same core questions across ten companies make it possible to read across cases: how did each company's 8-K compare with its letter?
  • The reasoning is part of the answer. Beneath every answer is the graph it was built from. See Reasoning and evidence.
