Guest prep for podcasts

Your guest arrives prepared. So do you.

Paste the guest's name and one link. Antecena sends a branded invite, builds a dossier with a source behind every claim and suggests a rundown and script, inside the Claude, ChatGPT or Gemini you already use. You decide; your data stays in your account.

The problem

Every host has improvised a question.

Preparing for a guest takes work: finding what they have already said, separating fact from opinion, thinking of questions nobody has asked them yet. In the rush, you end up googling the guest on the way to the studio.

And the AI tools that promise to help often make things up about people and never say where each sentence came from. You only find the mistake once it is on air.

How it works

From invite to subtitles, in one flow.

  1. InviteThe invite carries your show's branding and tells the guest what will happen.
    Free
  2. Form with consentThe guest answers in your own Google Forms and chooses what to share. Sensitive data only comes in if the guest declares it.
    Free · full form on paid
  3. Dossier with a source per claimEvery sentence is tagged verified, self-reported or inference, with its source. What we could not find shows up as “not found”.
    Free
  4. RundownThe episode's topics: the guest profile crossed with your editorial line and with what is trending.
    1 track free · 3 on paid
  5. ScriptQuestions in your show's tone, as full script, teleprompter or cue card.
    1 mode free · 7 on paid
  6. MemoryShow catalog, search and lessons from each episode, so the next rundown builds on the previous ones.
    Paid
  7. SubtitlesTranscription, translation and subtitles with quality checks, running on your own key.
    Free (local)

A source behind every claim

You know what you can say on air.

The dossier separates three kinds of information, and the rule lives in the product's data contract, not in a promise: a verified claim needs a source; an inference must say which claims it came from.

Example with a fictional guest.

Dossier: Ana Ribeiro (fictional)

  • VerifiedPublished the book “Cities that listen” in 2021.Source: publisher's page · national library catalog
  • Self-reportedCoordinates an urbanism collective in Recife.Source: form answered by the guest
  • InferenceLikely enjoys talking about walkable cities.Basis: the two claims above. Confirm before using.

Why it is different

What you can check today.

Shows the source

Verified, self-reported or inference on every sentence. “Not found” is a valid answer, not a bug.

You decide

Antecena recommends and warns, including about single sources. If you go against a warning, the call is yours and it is logged.

Your data stays with you

Guest answers stay in your Google Sheet; the dossier in your files. Our server keeps only license and usage.

Consent at the source

The form asks for separate, highlighted consents. Sensitive data only comes in if the guest declares it.

In the AI you already use

Claude, ChatGPT, Gemini, Hermes, OpenClaw and Antigravity. No new sign-up.

FAQ

Before you start

How much time will I save?

We have not published a number yet. The beta with real hosts is measuring it, and we will show the result as it comes. Meanwhile, the Prep Diary measures your time, on your own computer.

Won't the AI make things up about the guest?

Every claim says whether it was verified (with a source), self-reported by the guest, or is an inference. What we could not find shows up as “not found”. Click and check.

Do I need to learn a new app?

No. Antecena runs inside Claude, ChatGPT, Gemini and other assistants you already use. See install.

Where does my guest's data live?

In your account: form answers go to your Google Sheet and the dossier stays in your files. Our server keeps only the license and usage. Details in the Privacy Policy.

What if I cancel?

You go back to the free plan and keep everything you created. Cancellation takes effect at the end of the paid period.

What if I change my mind?

You have 7 days from purchase to withdraw with a full refund (Brazilian Consumer Code, art. 49). Paddle's own refund policy may give you more depending on your country. See the Refund Policy.

Solo or Duo?

Solo works on 1 device or assistant; Duo on 2 (for example, Claude on your laptop and ChatGPT on your phone).

Who charges me?

Payments are processed by Paddle, our reseller and merchant of record. Paddle issues the receipt and handles the taxes for your country.

I run a network with several hosts.
