Communicate better. Build stronger relationships.
Built for iOS, AI Reply Assistant grounds every reply in your real conversations, relationships, and schedule — drafting, organizing, and acting across WhatsApp, Telegram, Instagram, and Messenger, so everyday messaging deepens connections and repetitive work disappears.
Our AI comprehends the surrounding conversation, enabling functionality beyond message drafting. Efficiently summarize extensive threads, convert key information into calendar events and reminders, customize voice and capabilities through Skills tailored to your communication style, and integrate Claude for advanced reasoning tasks. This solution supports authentic responses, enhanced organization, and improved decision-making—all accessible with minimal interaction.
Smart Reply. Three on-device drafts in your tone, each tagged — tap one to send.
• Priya shared the venue for Saturday's dinner.
• Daniel asked if everyone can make it by 7.
• You offered to bring dessert.
Analyze. A day summary with events and reminders ready to add in a tap.
Skill. A full draft in the voice of your active Skill — set the suggestions, instructions, and filters.
Discover open-source agent skills for Claude Code, Codex, ChatGPT, and any tool that uses SKILL.md.
Skills Marketplace. Import an open-source Skill from GitHub — browse by keyword, creator, or occupation, then make any one your own.
Reply in our brand voice — warm, clear, and confident. Skip the jargon and never over-promise.
Custom Skills. Build your own — a name, a system prompt, and behaviour sliders dial the voice in until it sounds like you.
Always cite the source document. Prefer the brand guidelines for tone and wording questions.
PDF, Office, iWork, images, and more supported.
Everything is processed and stored on your device.
Knowledge Base. Attach documents and URLs the AI references when it drafts — processed and stored on your device.
AI Tools. Enable a Skill’s tools — the AI calls them on device, shows each one inline, and you confirm before anything’s sent.
Claude. Chat with Claude right inside the app — advanced reasoning on prepaid AI Credit or your own Anthropic key.
Two chats need a reply — Priya is waiting on a time for Saturday and the Design Team needs your sign-off. The rest is catch-up reading.

Summary. A digest of every unread chat — what needs a reply and what’s just FYI.
Writing, creating, automating, and translating — the things you already do on your iPhone, made faster where you already do them. AI Reply Assistant builds on Apple’s own frameworks, so the capability sits directly in the typing interface rather than in another app.
Writing Tools. Proofread, rewrite, and summarize selected text with a tap.
Image Playground. Create fun, original images in the conversation — Animation, Illustration, or Sketch, all on device.
Apple Shortcuts. Your conversations, messages, contacts, quick replies, scheduled messages, and Skills are all in the Shortcuts app to build with — the way Reminders and Calendar are. You choose what a message is about, and today’s details fill themselves in.
AI-powered replies to unread messages
Share a random photo with an AI caption
Relay messages from one conversation to another
Ask a question, get an answer from your chats
Set up a new AI writing style
Shortcut Templates. Automations already built, in the app’s own gallery — reply to everything unread, send a photo memory, clone a group’s members onto another network. Add one in a tap, then customise it.

Matched a poll option
One search, every platform — and it reaches inside polls, events, and shared locations.
Personal Context. Your conversations join the on-device index Siri AI and Spotlight already search — so one search covers all four platforms, right down to what is inside a poll, an event, or a shared location.
Translation. Inline translation across every message type — text, captions, polls, events, link previews, profile bios, and transcripts. 20+ languages, entirely on-device.
Transcription. On-device transcription of voice messages, videos, video notes, audio files, documents, and shared reels and stories — over 30 languages and dialects.
Certain communications merit preservation—welcoming greetings, refined outreach, and optimally crafted responses. Save messages once and enable automatic personalization through dynamic variables, such as the recipient’s name, to ensure each interaction appears bespoke. Curate a repository of frequently utilized, high-quality messages, merge birthdays across your platforms so none passes unnoticed, and streamline thoughtful communication with a single tap.
Quick Reply. Saved messages and attachments, inserted in a tap — right above the keyboard.
Variables. Tokens like {recipientName} and {currentDate} fill in with the recipient’s details the moment a saved message is inserted.
WhatsApp 3Telegram 5576Birthdays. Birthdays merge across WhatsApp, Telegram and iOS Contacts — with a one-tap greeting in your own words.
Send quick preset replies to a contact
Quick Reply widget. Pin a Quick Reply widget to your Home Screen, then long-press to point it at any conversation — or the most recent — and choose which replies it shows.
Here’s an uncomfortable truth: your customers have already forgotten what you sold them. What they remember is how you made them feel when they needed you. And nothing shapes that faster than how quickly you reply. A same-day answer says “you matter.” A three-day silence says the opposite — however good the product was. So treat every reply like a first impression, because to the person waiting, it is. How fast do you get back to yours?
AI Writer. Pick an occasion, answer a few questions, and Apple Intelligence drafts a polished speech, post, or message on device — refine it, then save it as a Quick Reply.
WhatsApp, Telegram, Instagram, and Messenger, side by side. Conversations from every platform coexist in a single unified experience — use your Telegram stickers and premium custom emoji in WhatsApp chats, apply interactive mask stickers, and schedule messages across services. One inbox brings all four together, each with its own strengths.

Priya SharmaPendingHappy birthday! 🎉 Hope you have a wonderful day — let’s catch up this week.
Team StandupScheduledReminder: daily standup in 10 minutes. Drop your updates in the thread.
Book ClubPendingReminder — this month’s pick is due Friday. See you all at the meetup!
Scheduled Messages. For when you already know what you want to say and won’t be free to say it. You write it once and that’s what arrives — recurring, one-off, or one message to thirty people. Bulk sends are paced automatically, so reaching everyone does not put the account you use every day at risk.
AI Reply Assistant connects to WhatsApp and Telegram on-device, transmitting messages directly from your device to the network to maintain end-to-end encryption without a Flowbie server in between. Instagram and Messenger connect through the on-device Messagix bridge — again straight from your device, with only the session stored locally. Apple Intelligence is incorporated via on-device processing. You retain control over Claude: on your own key it goes directly to Anthropic, and with AI Credit it passes through a relay that stores nothing.
The agent searches message tools only within these conversations.
Conversation scoping. You decide which conversations the agent can read — it searches only the chats you scope, never your whole inbox.
Use Face ID to open this chat. Locked chats are hidden from Widgets and notification previews are hidden.
Lock chats. Hide sensitive conversations behind Face ID — even AI Reply Assistant can’t peek.
Two ways in. Bring your own Anthropic API key, or buy prepaid AI Credit — no Anthropic account needed.
Credit never expires and is spent as you use Claude. Prices include the cost of running the model.
Claude, on your terms. Cloud Model is off by default, by your choice. Your own key goes direct to Anthropic; AI Credit is metered without your content ever being stored.
Start free on one platform. Claude is paid for separately — add prepaid AI Credit on any plan, or go Pro and bring your own key.

| Option to bring your own Claude key — adds Managed Agents, Agent Skills, and Files | Included |
AI Credit gets anyone started in a minute — no subscription, no Anthropic account. Bringing your own key is the full-surface tier: you deal with Anthropic directly, and Managed Agents, Agent Skills, and Files come with it. Context is not part of the difference — every model runs at its full native window on either route.
| Compare | AI Credit Prepaid top-ups · any plan | Your own API key Pro plan · direct to Anthropic |
|---|---|---|
| Who it’s for | Anyone — no subscription, no Anthropic account, no API key | Pro subscribers who want the full Claude surface and a direct Anthropic relationship |

| Billing | Prepaid credit in dollars, spent as you use Claude. Never expires; pack prices include the cost of running the model.

| Privacy path | Through Flowbie’s relay — content is never stored; logs carry only billing metadata | Straight to Anthropic under your own account — Flowbie is never in the path |
| If you have both | Your balance sits untouched — it is not spent while a usable key is connected | Your key serves every request, so you are never charged twice for the same reply |
Claude needs one of two things: prepaid AI Credit, or your own Anthropic key on Pro. A subscription by itself does not include Claude usage — here is every combination.
| Your setup | What you get |
|---|---|
| Free plan · no AI Credit | Claude is off. Apple Intelligence still runs Smart Reply, Skills, Analyze, Summary, and AI Writer on device — 10 actions a day. |
| Free plan · AI Credit | Claude is on. Agent chat, cloud Smart Reply and Skill drafts, and 17 of the 19 tools — no subscription needed. |
| Pro · no key, no AI Credit | Claude is off. Pro on its own does not include Claude usage — add AI Credit or connect your own Anthropic key. The on-device AI actions the Free plan caps at 10 a day are uncapped on Pro. |
| Pro · AI Credit | Claude is on, spent from your prepaid balance. Same surface as the Free plan with credit. |
| Pro · your own key | Claude is on, billed by Anthropic to your own account. Adds Managed Agents, Agent Skills, and Files. |
| Pro · your own key · AI Credit | Your key serves every request and your credit is left untouched — you are already paying Anthropic, so we never spend the balance on top. |
On AI Credit you pick any of the three models at its full context window — the model list is never gated by how you pay. Requests are metered against your balance as they run, and when it is spent Claude asks you to top up.
| AI Credit packs | Price | Credit added |
|---|---|---|
| Small | US$4.49 | $3.00 |
| Medium | US$14.49 | $10.00 |
| Large | US$49.99 | $35.00 |
Starting Pro? The first US$2.00 is on us. Start any Pro plan and sign in with Apple, and US$2.00 of AI Credit lands in your balance automatically — once per Apple Account.
The App Store charges in your local currency. Credit is spent at Anthropic's standard model rates as you use Claude, never expires, and pack prices include the cost of running the model.
Both WhatsApp Personal and WhatsApp Business App accounts work — AI Reply Assistant links as a companion device using WhatsApp's Multi-Device protocol, just like WhatsApp Desktop. (The server-side WhatsApp Business API for large enterprises is a different product and isn't used.) On Telegram, all user accounts are supported — Personal, Premium, Business, and anonymous Fragment-number accounts; bot accounts can't log in. Instagram works with personal and professional (creator or business) accounts, and Messenger with your Facebook account — for both, you sign in on Meta's own page and only the session is stored on-device. The full comparison is in the FAQ.
One account per platform — one each of WhatsApp, Telegram, Instagram, and Messenger, side by side in the unified inbox. The Free plan connects one platform at a time; Pro connects all four at once.
AI Reply Assistant runs on iPhone and iPad with iOS 26 or later, and on Apple Silicon Macs (M1 and later) as the iPad app on macOS Tahoe 26. Apple Intelligence features need an Apple Intelligence-capable device — iPhone 15 Pro and later, or any iPad or Mac with an M1 chip or A17 Pro and later. Not available on Apple Vision Pro, Android, or the web.
Absolutely. Apple Intelligence is integrated into the core of AI Reply Assistant through on-device processing — Smart Reply, Writing Tools, Image Playground, and more, no API key required, and no Claude of any kind needed. With Claude, you get even more expertise to handle more complex requests — extended thinking, AI tools, multimodal understanding, document creation (on your own Anthropic key), and a far larger context window: roughly 50x the on-device model on AI Credit, and up to 250x on your own Anthropic key.
