Overview
MailHero by AISaver is an AI context assistant that helps users understand and respond to email conversations directly from Gmail™.

MailHero only reads the Gmail™ conversation that the user explicitly opens. It does not scan the inbox or process email in the background.

Key features:

• Analyze the currently opened Gmail™ conversation and generate a structured Case Brief.
• Review conversation participants, message counts, dates, decisions, important facts, and action items.
• Generate editable AI-assisted replies using the full conversation or only the latest message.
• Improve and translate reply drafts before creating a Gmail™ draft.
• Create Gmail™ reply drafts only after an explicit user action. MailHero never sends email automatically.
• Save a user-selected email conversation or Case Brief to an authorized Notion database.
• Reuse selected Notion records as context for future replies.
• Export the current conversation as Markdown for copying.
• Choose the interface language and AI output language.
• Use MailHero’s managed AI service or a user-configured OpenAI-compatible provider.

Privacy and control:

MailHero processes only the Gmail™ conversation explicitly opened by the user. Email content is never scanned automatically, automatically saved to Notion, or automatically sent. Creating a Gmail™ draft and saving information to Notion always require an explicit user action.

Notion integration is optional. Users authorize their own Notion workspace and select which pages or databases MailHero may access.

No separate MailHero account is required for the core workflow. Users may optionally connect their own compatible AI service and their own Notion workspace.
