Plans
Read the record. Reason through it. Decide with it.
EphemerisX reads the primary record behind high‑risk decisions: what regulators, investigators, companies and courts actually wrote. Reading it is free, for anyone learning and researching. Pro, in early access, is being built to reason across every domain of it at once, so you can decide with the evidence in front of you and derisk a business, an investment, or anything big.

Tell us who you are and the question you would bring first. The questions people send shape which domains and reports come first.
Questions
Is Pro available now?
Not yet. Pro and Team are in development. The preview above shows how they are designed to work, using real figures from the public record. Early access members hear first and get the founding price.
Will the public record stay free?
Yes. The Ephemeris, the FDA record, the drug pages and every public case stay free to read.
Does AI write the answers?
In Pro, a model writes the answer, and every claim in it is cited to the document and page it rests on; claims that cannot be traced are left out. Quoted text stays quoted. The free public record is unchanged: quotes only, nothing written by a model.
Why is it more reliable, and cheaper, than asking an AI?
An AI model asked about thousands of documents has to re-read them for every question, and can weigh them differently each time. EphemerisX reads each document once into a knowledge graph where every fact points to its page, then reasons over that graph. Answers are checkable, the cost doesn’t grow with every question, and the effort goes into finding connections, differences and weaknesses. Read why a knowledge graph →
Is this investment advice?
No. EphemerisX reports what public records say and when. It does not recommend trades or predict prices.
How does the Team plan work?
Pricing starts at $1,500 a month for up to five seats. It includes the API and connectors into the systems your team already runs (documentation, risk, analysis, tracking and project management), scoped and built with you, including for systems developed in house. Join early access and we’ll set it up with you.
