The headless AI support SDK
built for developers.
Embed AI-powered support on any site in 5 minutes. No per-seat fees.
RAG-powered answers from your docs. Usage-based pricing. No credit card required.
What is EchoSDK?
EchoSDK is a headless helpdesk platform that lets developers embed an AI-powered support chat widget on any website with a single script tag.
It uses retrieval-augmented generation (RAG) to answer customer questions directly from your documentation, automatically escalates unresolved queries into support tickets, and integrates with Slack for real-time team notifications.
- Who is it for?
- Developers and SaaS teams who want to add AI-powered customer support without managing helpdesk infrastructure.
- How does it work?
- Ingest your docs via URL or text. EchoSDK creates vector embeddings and serves RAG-powered answers.
- What does it cost?
- Usage-based pricing. Free tier with 1k queries/month. Pro plan at $49/month. No per-seat fees.
- What makes it different?
- Headless architecture, developer-first APIs, and a 5-minute setup compared to weeks with traditional helpdesks.
The support platform tax is killing your margins
Traditional helpdesks charge per agent. EchoSDK charges per query. The math is simple.

Frequently asked questions
What counts as a query?
A query is any question asked to the AI. Follow-up messages in the same conversation count as separate queries.
Can I upgrade or downgrade anytime?
Yes! You can change your plan at any time. Upgrades take effect immediately, downgrades at the end of your billing period.
What happens if I exceed my query limit?
We'll send you a notification. You can either upgrade your plan or purchase additional queries at $0.001 each.
Do you offer refunds?
Yes, we offer a 30-day money-back guarantee for all paid plans. No questions asked.
