FAQ

Common questions about AI assistants, channels, billing, voice calls, and integrations on Happ

Happ is an AI assistant platform that automates customer communication across messaging channels (Telegram, Instagram, WhatsApp, Facebook, Viber) and voice calls. Your AI assistant responds to customers automatically using the knowledge and instructions you provide.

Do I need technical skills to use Happ?

No. Happ is designed for non-technical users. You can set up an AI assistant, connect channels, and manage conversations entirely through the web dashboard at my.happ.tools — no coding required. The API is available for developers who want to build custom integrations.

Which AI models can I use?

Happ supports multiple providers and models:

OpenAI — GPT-4o, GPT-4o Mini, GPT-4 Turbo, GPT-4, GPT-3.5 Turbo
Claude (Anthropic) — Sonnet 4.5, Sonnet 3.7, Sonnet 3.5, Opus 3.5, Opus 3, Sonnet 3, Haiku 3
Gemini (Google) — 2.0 Flash, 1.5 Pro, 1.5 Flash, 1.5 Flash 8B
Groq — GPT-OSS 120B (ultra-fast inference)

See Assistants > AI Model Configuration for the full list.

Can I use multiple AI assistants?

Yes. You can create multiple assistants, each with its own prompt, knowledge base, tools, and AI model. Assign different assistants to different channels or use cases.

Channels

Which messengers are supported?

Telegram, Instagram, WhatsApp, Facebook Messenger, and Viber. See the Channels Overview for details on each.

Can one assistant work on multiple channels?

Yes. A single assistant can handle conversations on all connected channels simultaneously. Each channel creates separate conversations per customer.

What happens if I disconnect a channel?

Active conversations stop receiving AI responses. Historical conversation data is preserved. You can reconnect the channel at any time.

Do customers know they're talking to an AI?

That's up to you. Configure the assistant's prompt to identify itself as AI or present itself as a regular support agent.

AI & Conversations

How do I improve my assistant's responses?

Refine the prompt — Add specific instructions, tone guidelines, and examples
Add knowledge — Upload documents, FAQs, and website content to the Knowledge Base
Use a better model — GPT-4o and Claude Sonnet 4.5 produce higher quality responses
Review conversations — Check the Chat Dashboard to identify patterns where the assistant struggles

Can the assistant perform actions (not just chat)?

Yes. Configure tools to let the assistant call external APIs — make bookings, update CRM records, check availability, look up data, and more.

What happens when the assistant can't answer?

The assistant responds based on its prompt instructions (e.g., "I don't have that information, let me connect you with a team member"). You can configure the turnOffAiMode built-in tool to automatically disable AI and alert your team via Telegram Push Notifications.

Can a manager take over a conversation?

Yes. Toggle AI off for any conversation — manually from the dashboard/mobile app, via the /bot command in Telegram, or automatically via the turnOffAiMode tool. When AI is off, you can respond manually. Set up Telegram Push Notifications to alert your team when handoff occurs. See AI Control & Human Handoff for full details.

How fast does the AI respond?

Typically within a few seconds. Happ uses a 4-second debouncing system — if a customer sends multiple messages in rapid succession, the assistant waits and processes them together. You can tune response behavior with the eagerness setting on voice assistants (Eager, Normal, Patient).

What is the context window?

The AI assistant sees only recent messages (approximately the last 10 minutes). Older messages are archived but preserved in the database. This keeps responses focused and token usage efficient. See AI Control > Context Window.

Does AI automatically turn back on after handoff?

Yes. If AI mode is turned off and there's no activity for approximately 10 minutes, AI automatically resumes. This prevents conversations from being left in manual mode indefinitely.

Voice

How does the voice assistant work?

The voice assistant answers phone calls using AI. It converts speech to text (STT), generates a response using your configured AI model, and converts it back to speech (TTS) — all in real-time. It can also execute tools during calls. See Voice Assistant.

Which telephony providers are supported?

Binotel, Ringostat, Phonet, and Unitalk. Any SIP-compatible provider can potentially be used. See Telephony Providers.

Can I choose the voice?

Yes. Choose from 30 built-in voices or connect ElevenLabs for premium natural-sounding voices with multiple languages and accents.

Billing

What plans are available?

Happ offers separate plans for text and voice:

Text plans (messenger assistants): Creative ($200/mo), Pro ($500/mo), Pro Plus ($1,000/mo) Voice plans (phone call assistants): Mini ($100/mo), Base ($250/mo), Pro ($500/mo)

See Billing & Plans for full details.

How are tokens counted?

Tokens are consumed when the AI processes and generates text. Longer conversations, more capable models, knowledge base searches, and tool calls all consume tokens. Monitor usage in Settings > Billing.

What happens when I run out of tokens?

Your assistants may stop responding until tokens are replenished (at your next billing cycle or by upgrading your plan).

Can I change my plan?

Yes. Upgrade at any time for immediate access. Downgrades or cancellations take effect at the end of your billing period.

Data & Security

Is my data secure?

Yes. Happ uses industry-standard security practices:

JWT-based authentication with access tokens
HTTPS encryption for all data in transit
Data isolation between companies
HMAC-SHA256 webhook request signing
