Our Offerings

AI Chatbots & Virtual Assistants Services We Provide

01

Customer Support Chatbots

LLM-powered support agents trained on your help docs, policies, and past tickets that resolve 60-80% of routine queries autonomously. Seamless human handoff with full conversation context for everything else.

02

Lead Generation & Sales Bots

Website assistants that qualify visitors, answer product questions, book demos, and push enriched leads into HubSpot or Salesforce. Clients typically see 2-3x more qualified conversations than static contact forms.

03

WhatsApp & Multichannel Bots

One conversational brain deployed across WhatsApp Business API, Instagram, Facebook Messenger, web, and SMS. Especially powerful in markets where WhatsApp is the default customer channel.

04

Internal Employee Assistants

HR, IT helpdesk, and knowledge bots inside Slack and Microsoft Teams that answer policy questions and raise tickets automatically. Companies recover hundreds of staff hours monthly from repetitive internal queries.

05

Voice Assistants & IVR Modernization

Natural-language voice bots built on speech-to-text and LLM pipelines that replace frustrating keypad IVR menus. Callers state their issue in plain language and get routed or resolved in seconds.

06

Chatbot Analytics & Optimization

Dashboards tracking resolution rate, CSAT, escalation reasons, and conversation drop-offs with monthly tuning cycles. We treat launch as the starting line — bots improve measurably every month they run.

How We Work

What You Get In Writing

Terms that go into every agreement we sign. See all client commitments.

A Written Price Before Work Starts

Every job gets a scope and a number in writing first — a fixed price for defined work, or an hourly rate with a capped estimate. If scope changes, we re-quote before we build, not after.

You Own the Code

Source code, designs, and data are yours. We work in your repository where possible, hand over full documentation, and transfer everything at the end. No license fees, no hostage situations.

NDA Before You Share Anything

We sign your NDA — or send ours — before the first technical conversation. Your idea, your data, and your customer information stay confidential during and after the engagement.

FAQ

AI Chatbots & Virtual Assistants — FAQs

Everything you need to know before starting your project. Still have questions? Talk to our team.

Customer support bots, sales and lead-gen assistants, WhatsApp commerce bots, internal HR/IT helpdesk bots, and voice assistants — powered by GPT-4o, Claude, or open-source LLMs with RAG over your knowledge base. All include human handoff and full conversation logging.

A focused FAQ or support bot launches in 3-6 weeks; a multichannel assistant with CRM integration and custom workflows takes 2-3 months. We start with a pilot on your top 20-30 query types and expand from real usage data.

Development ranges from $8,000 for a knowledge-base bot to $40,000+ for multichannel assistants with deep integrations. Running costs are modest — LLM API usage for a bot handling 10,000 conversations/month typically runs $100-$500/month.

Yes — all code, prompts, knowledge-base pipelines, and conversation data belong to you, hosted in your own cloud and accounts. Your data is never used to train third-party models, and we configure zero-retention API settings by default.

Responses are grounded in your approved content via RAG, with guardrails that decline out-of-scope questions and confidence thresholds that trigger human handoff. We review flagged conversations weekly during the first 90 days and tune until accuracy stabilizes above 95% on covered topics.

90 days of included tuning post-launch, then optional retainers from $500/month covering knowledge updates, new intents, performance reports, and model upgrades. Most clients see resolution rates climb 10-20 points over the first six months of optimization.
