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.

Every SIM DAD tool works 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.

--open ibis: Private, local transcription. Watch folders, plug-in recorders, consent capture, redaction review, and a tamper-evident chain of custody.
--open lector: Write it, hear it back. Read-aloud with word-level highlighting, editorial marks that survive edits, source and formatted views of one document.
--open velamen: De-identification you can defend. Checksum-validated detection, reviewable findings, and a redaction certificate for every run.
--open orator: Present what you already wrote. Outline in, narrated and chaptered video out, voiced entirely on your machine.

# Morning: yesterday's interview is already a transcript, waiting in the suite feed
$ resero --open ibis  ~/Research/interviews/

# Afternoon: hear the draft read back, mark what needs fixing, strip names before sharing
$ resero --open lector  ~/Research/draft.md

Everything at rest is encrypted with age, keyed to your operating system’s credential store. Nothing phones home. The one network call any tool can make, a model download, is announced in the interface while it happens. Recordings, drafts, and data never leave the machine unless you export them yourself.

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.

Local-first is a claim. The workbench is the proof.

Coming soon at $159. One-time purchase, no subscription. Windows, with updates included. Every tool works standalone; the workbench is where they become more than the sum.

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 (announcement soon). 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, Associate Professor at SIUE. 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.
