Helpful replies.
Clear guardrails.

ReplyPilot helps prepare thoughtful, contact-specific replies while keeping each rule visible, editable, and under your control.

01 · CONTACT RULES

You choose the people

Create named rules for selected contacts, write a fixed fallback reply, and switch auto-reply or AI drafting on or off for each rule.

02 · LOCAL STYLE

Shape how replies sound

Use guided writing questions, a conversation narrative, and approved talking points stored on your iPhone.

03 · SAFETY CONTROLS

Stay helpful, never spam

Set response delays, schedules, cooldowns, daily limits, urgent phrases, and reply-loop protection.

04 · ON-DEVICE DRAFTING

Private when supported

Compatible devices can use Apple's on-device intelligence. A fixed local reply remains available when on-device drafting is unavailable.

05 · HONEST SETUP

Apple stays in control

ReplyPilot guides the personal Message automation setup. You approve it, and Apple's Send Message action performs sending.

06 · NO MESSAGE HISTORY

Your conversations stay private

ReplyPilot does not read the Messages database, monitor Messages in the background, or upload your conversations to a cloud AI service.

Set up in four
clear steps.

Apple protects Messages and personal automations. ReplyPilot guides every required step while Apple Shortcuts remains in control.

Create a rule

Choose a trusted contact, fixed reply, drafting mode, and safety limits.

Open Shortcuts

Choose the personal Message automation and the same approved sender.

Connect ReplyPilot

Pass the current message as Shortcut Input to ReplyPilot's Prepare Auto-Reply action.

Add Send Message

Use Apple's Send Message action with the prepared text, then run a real test.

Important: ReplyPilot cannot create, inspect, enable, or verify your personal Message automation. Automatic behavior depends on the automation, permissions, and iOS settings you approve in Apple Shortcuts.

Privacy is the
architecture.

The shipping app is built around local data and the information you explicitly pass into a Shortcut.

What stays local

  • Your selected contacts and reply rules.
  • Your writing examples and approved talking points.
  • Your current Shortcut Input while ReplyPilot prepares a response.
  • Your safety settings and local usage history.

What ReplyPilot does not do

  • Read your Messages database or conversation history.
  • Monitor incoming texts in the background.
  • Send SMS or iMessage directly from the app.
  • Upload message text or contacts to a Black Thorn Labs cloud AI service.
