01 How an answer is built

Every answer points to its page.

Reticenda does not write answers. It finds them in your documents and shows you where they are, so you can read the page before you rely on it.

  1. You ask, in your own words

    Type a question the way you would ask a colleague. Nothing you type leaves the phone.

  2. It searches by words and by meaning

    The search runs on the device and finds passages that say the same thing in different words.

  3. It shows the passage and the page

    Each Finding quotes the document and names the page it came from, one tap from the original.

  4. When the answer is not there, it says so

    If your documents do not contain an answer, Reticenda tells you, instead of guessing.

02 Six things you do with a case

From the first page to the handover.

  1. Open

    Create a case, choose your profession so the app speaks your vocabulary, and set the PIN that protects the vault.

  2. Add

    Scan paper with the built-in scanner, import PDFs and images, or share files in from another app. Duplicates are recognised.

  3. Read

    Read the original page beside the text taken from it, and search inside any document.

  4. Organise

    File documents by type, date, parties and tags, keep notes beside them, and archive what is finished.

  5. Ask

    Ask questions across a case and get the passage and page, or an honest statement that the answer is not there.

  6. Prove

    Make a Seal that records what the app did, export redacted documents, and keep an encrypted backup.

03 Private by construction

Private because it cannot connect, not because we promise.

On Android, Reticenda does not hold the internet permission. The operating system itself refuses it a network connection, and the app shows you the permissions it holds, read from Android rather than from a list we wrote.

  • No internet permission

    Android will not give the app a network socket, so your documents cannot be sent anywhere.

  • Encrypted on the device

    AES-GCM, under a key protected by the phone's secure hardware, with your PIN as a second factor.

  • No accounts, analytics or ads

    There is nothing to sign up for, and nothing that watches how you use the app.

04 In the vault

Built to be relied on, and to be checked.

No internet permission

Android itself refuses the app a network connection, so your documents cannot be sent anywhere.

An encrypted vault

Everything is encrypted on the phone under a key protected by its secure hardware, with your PIN as a second factor.

Answers with the exact page

Ask a question across a case and get the passage that answers it, with the document and page it came from.

Chronologies and summaries, cited

Build a chronology or a summary over a whole case from the documents' own words, every line cited to its page.

Scan, import, share in

Scan paper with the built-in scanner, import PDFs and images, or share files in from another app.

Cases, filed properly

Keep each piece of work in its own case, filed by document type, date, parties and tags, with notes beside it.

Seals: proof of what the app did

A Seal is a signed record of which documents were processed, their fingerprints and the state of the app. Free on every plan.

05 Proof of what it did

A Seal records how your documents were handled.

A Seal is a signed record, made on your phone, of which documents were processed, their fingerprints and the state of the app. Anyone you give it to can check it. Making, saving and checking Seals is free on every plan.

A Seal is a technical record, not a legal conclusion: it does not decide whether a document is authentic, privileged or admissible.

07 Questions

Before you ask.

All questions

Does the AI write answers?

No. Reticenda finds passages in your documents and shows them with the page they came from. It does not generate text, and when the answer is not in your documents it tells you.

Can you read my documents, or recover them for me?

No. We never receive them, and we have no technical means to open your vault. That is also why nobody can recover it if you forget your PIN.

What happens if I forget my PIN?

The vault cannot be opened again, by you or by anyone. This is the cost of a design that keeps it private, so keep an encrypted backup and your original documents.

Your documents stay yours. Their answers come with the page.
