Resero: the SIM DAD workbench.

What Resero is

Resero (Latin reserō: I unlock) is the workbench that holds the whole SIM DAD suite: one window where your transcripts, drafts, analyses, and videos live together, entirely on your machine.

Ibis, Lector, and Orator each work standalone. Resero is what they add up to: record an interview and Ibis transcribes it, the transcript opens in Lector where you write with your ears as well as your eyes, Velamen strips what must never leave, and Orator presents what you wrote: one workflow, on your own hardware, with nothing sent anywhere. No cloud, no account, no telemetry. For turning a corpus into numbers and charts, TASS is the companion instrument: a separate product that Resero hands corpora to and receives results from, never a bundled component.

The suite
Ibis
Private, local transcription. Watch folders, speaker turns, redaction review, and export to Word, VTT, CSV, or JSON.
Lector
Write it, hear it back. Read-aloud with your system voices, source and formatted views of one document, and find and replace built for long files.
Velamen
De-identification review. Finds structured identifiers by shape and checksum, shows every finding for review before it is replaced, and records what ran and what was found. Built to support a Safe Harbor review, not to certify one.
Orator
Present what you already wrote. Outline in, narrated and chaptered video out, voiced entirely on your machine.
A day with Resero

In the morning, yesterday’s interview is already a transcript, waiting in the suite feed.

By afternoon, you hear the draft read back, mark what needs fixing, and strip names before sharing.

Privacy

Everything at rest is encrypted with age, keyed to your operating system’s credential store. Recordings, drafts, and data never leave the machine unless you export them yourself.

Why this exists

Researchers, clinicians, lawyers, and journalists work with material that cannot go to someone else’s cloud. The tools they are offered anyway are subscriptions to other people’s servers. Resero exists so the private path is also the good path: one workbench where serious tools share one workflow, and the data stays where the duty of care lives, with you.

Status
Resero SIM DAD LLC, 2026

Coming soon at $159. One-time purchase, no subscription. Windows and macOS, with updates included. Ibis, Lector, and Orator each work standalone; the workbench is where they become more than the sum. Ask for early access to hear first when there is a build to try.

Bought on their own, Lector ($29), Ibis Pro ($59), and Orator ($129) come to $217. Resero is $159, and it adds Velamen and the shared workbench, neither sold separately.

The free, MIT-licensed age-file decrypter previously introduced on this page is not going away; it continues, free, under a new name. Its promise is unchanged: decrypt your own data without us in the loop.

The practice behind the software

We built this for our own work first.

Resero exists because running these tools side by side in one workspace was how we already worked.

SIM DAD LLC is a communication consulting practice led by Dr. Alex P. Leith. We audit and strengthen external communications, design and run studies, collaborate on federal and foundation grants, and deliver workshops. The software comes out of that work rather than the other way round.

If it is the methods you need rather than the tool, see what the practice does or start a conversation.
