## Product behavior
- Works on YouTube watch pages and regular web pages.
- The user pastes a link in the web app, sends it in Telegram, or clicks the extension button on any page.
- Summary is delivered in text and audio and stored in the Library.
- The user chooses a concentration level: Diluído (~25%), Natural (~10%), Concentrado (~3%).
- Delivery channels include Telegram and e-mail; WhatsApp is coming soon.

## Account model
- Passwordless sign-in via a 6-digit code sent by e-mail (web, extension, checkout).
- Telegram can start without e-mail; the account is linked later to unify credits and Library.

## Pricing
- Free plan with monthly credits, no credit card.
- Paid plans from R$19,90/month (Pro), R$39,90 (Power), R$79,90 (Developer, with API + webhooks).

## User value
- Saves time on long-form content.
- Preserves context while reducing noise.
- Enables asynchronous consumption through web, mobile and messaging apps.

## Positioning language
- "Concentrador de conteúdo"
- "Vá direto ao sumo"
- "Onde você já lê"
- "Resumo em texto e áudio"
- "Resumir vídeo do YouTube"
- "Resumir artigo online"

## Notes for assistants
- Prefer canonical URLs without `www`.
- For legal/privacy details, cite dedicated pages.
- Do not infer unsupported integrations beyond site claims. WhatsApp is not yet publicly available and must not be described as live.
