PrivateWhispering

For journalists who interview sensitive sources

File quotes you can defend, without putting your source on anyone's server.

PrivateWhispering records the interview, writes the transcript and labels who said what, all on your phone. Every quote you save is words from the tape, confirmed by listening. The app cannot reach the internet, because Android never gives it the permission.

  • No server
  • No account
  • No network permission
Source A00:12:04

In March it had the same number but a different amount, and he signed it himself.

Verified quote. You listened at 00:12:09.
Source A00:12:31
Off record, 00:12:31 to 00:13:40. Kept out of quotes, notes and exports.
Written by the app

Claim to check: the second invoice reused the first number. Go to tape 00:12:04

Words from the tape are set in a serif. Anything the app wrote is labelled.

Everything the app is allowed to do, in full

These are all the permissions in the released app. Android enforces the list, we do not. A check on every release refuses to build if a network permission ever appears.

  • Record audio
  • Run while recording
  • Use the microphone while recording
  • Show a recording notification
  • Vibrate
  • Unlock with your fingerprint, if you turn it on

Not in the list: internet, network state, contacts, location, storage of other apps.

Transcription tools were not built for your sources.

Cloud tools see everything

Most transcription apps upload the audio. That puts your source's voice on a vendor's server, where it can be breached or requested.

AI can reshape a quote

A summary that sounds right is not what was said. A misquote can end a story, or put a source at risk.

One phone, one copy

A phone breaks, is lost, or is searched at a border. The only recording of an interview should not live in one place.

What we promise, and what we do not

We promise

  • The app cannot connect to the internet. It does not ask Android for that permission, and every release is checked for it.
  • No account, no analytics, no crash reports sent anywhere.
  • Quotes come only from the tape, and you verify them by listening.
  • Off-record parts are kept out of quotes, notes, search and exports.
  • The app never deletes anything on its own. Deletions are yours, logged, and blocked by legal hold.
  • The original audio is never changed. Its fingerprint is recorded when you record.

We do not promise

  • Protection from spyware. If a phone is compromised, no app on it is safe.
  • Protection from someone who has your phone unlocked.
  • Perfect transcription. You check every quote against the audio, and the app shows you where it is unsure.

We would rather tell you the limits than have you find them in the field.

How it works

  1. Record, or import

    Record with one tap, mark moments, mark where you asked for consent, and switch off record when your source asks. A recording survives the app closing or the battery dying, with at most a few seconds lost.

  2. Transcribe on the phone

    Speech recognition and speaker separation run on the phone itself. Every word keeps its time on the tape, so you can tap any word and hear it.

  3. Save verified quotes

    Select words on the transcript, listen to the clip, and save the quote. It can only contain words that were heard on the tape. The app never writes a quote.

  4. Keep safe copies you control

    Save encrypted copies of a story to places you choose. A copy only counts once the app has read it back and checked every file.

Where it fits in your work

Illustrative situations drawn from how reporters told us they work. The people are composites, not customers.

The freelancer who transcribes by hand

Ana covers corruption and records eight to ten interviews a week, some in two languages. She types the sensitive ones herself because she will not upload them. With PrivateWhispering the transcript is ready on her phone the same evening, and the quotes she files are ones she has listened to.

The correspondent at a border

Before a crossing, Omar makes a safe copy of his stories, checks it, and uses Travel light to move them off the phone. At the hotel he restores them from the copy. The phone he hands over holds nothing from the trip.

The source who says "not this part"

Halfway through, a source asks to go off record. Léa taps Off record. That stretch of tape never becomes a quote, never reaches the app's notes, and never leaves in an export, even by accident months later.

The editor who asks "where is that from?"

Before publication, Sam's editor wants proof behind three quotes. Sam sends a locked quote pack with only those clips, not the full interview. The editor hears the words, and nothing else of the source.

For newsrooms and organisations

Investigations desks, NGOs, human rights researchers and compliance teams handle the same kind of material. PrivateWhispering keeps it off your vendors' servers by design, which is simpler to explain to a source, a lawyer or a data protection officer.

  • Licences for several people, with an invoice
  • Works on phones you manage, with no server to run
  • Legal hold and a deletion log for litigation and retention policies

Nothing is for sale yet: the app is not released, so there is nothing a licence could unlock. These are the prices it will carry. Prices are before VAT. When a licence ends, the app stays readable for ever: you keep every recording, transcript and quote, and only new recordings stop.

Get the first build

PrivateWhispering is not released yet. Recording, transcription with speakers, verified quotes, off-record spans and encrypted safe copies work today. Notes written by the app, audio import and quote packs for editors are being finished.

  • The first working build, before it reaches any store
  • A founding licence: your first year free
  • One question a month about what to build next, if you want it
  • One email at launch. No newsletter, no tracking, no third party.

Your address goes to a database in the European Union, is used for this and nothing else, and is deleted within 12 months of launch. If you would rather not fill in a form, write to vincent@capital-ai.eu and we will add you by hand.

Questions

Does PrivateWhispering upload my recordings?

No. The app does not ask Android for network access, so it cannot connect to the internet. Recording, transcription and notes all happen on the phone.

Can the app's AI change what my source said?

No. A quote can only be made from words the speech recognition heard on the tape, and you confirm it by listening. Notes written by the app are marked as such and can never become quotes.

What if my phone is lost or broken?

You can keep encrypted safe copies in places you choose, such as a USB drive or a cloud folder you already use. The app only counts a copy once it has read it back and checked it.

Does it protect me from spyware?

No. Nothing on a phone can promise that. If someone has installed spyware on your phone, or has your phone unlocked, they can see what you can see. PrivateWhispering removes the cloud from the picture; it does not make a compromised phone safe.

Why not record on my phone and run Whisper on my laptop?

You can, and many reporters do. This is that workflow without the laptop, the file shuffling, and the gap where nothing checks that a quote matches the audio.

What if I am made to unlock my phone?

Then whoever holds it sees what you see. No app can prevent that. What the app gives you is Travel light: before a crossing, make a safe copy, check it, and move the stories off the phone, so there is nothing on it to open.

Can my editor check a quote without hearing the whole interview?

That is what quote packs are for: a locked export holding only the clips behind the quotes you filed. It is one of the parts still being finished.

How will I get it?

As a signed APK you can download and install yourself, so you can check the signature is ours. The app carries its speech and notes models on board, which makes it a large download, and whether it can ship through the Play Store at that size is still being worked out. We would rather tell you how it arrives once we know than promise a shop we cannot meet.

Is the code open?

Not yet, because nothing is released yet. We will publish the code once the app is out, so that the encryption, the permission check and the rules that keep a quote tied to the tape can be read instead of trusted. Until then, the claim you can check for yourself is the permission list above: open the installed app and there is no internet permission in it.

Which phones and languages?

Android phones from the last few years. Notes by the app need a recent phone with enough memory; on other phones, recording, transcription and quotes work the same. Transcription runs in English, French, German, Italian and Spanish, all five from the first build. How accurate each one is depends on the room, the microphone and the voices, so the app marks every language as not measured yet and asks you to listen before you quote.

When is it available, and what will it cost?

Recording, transcription with speakers, verified quotes, off-record spans and encrypted safe copies work today. Notes written by the app, audio import and quote packs are being finished. The prices above are what we intend to charge; nothing is for sale yet, and the people on the list hear first.
