The best AI site search for small sites

This is the biggest fork in the road. DIY engines like Meilisearch, Typesense and Orama are genuinely good software: fast, open source, and cheap to run at the infrastructure level. But "cheap on paper" hides the real cost — you need to stand up and host an instance, crawl or feed your content into an index, wire up a front-end, and (for AI answers) connect and pay for your own LLM. That is a fine trade if you have a developer and want full control. A managed service like Achla or AddSearch does all of that for you: the crawl, the index, the model calls and the billing sit behind one invoice, and you embed a single widget. If you would rather not run a search stack, managed wins on time-to-value; if you want to own every layer, DIY wins on control. Our Meilisearch comparison walks through this trade in detail.

There is a real gap in the market. At the top, enterprise-managed AI answers are expensive: AddSearch publishes its AI Answers tier at $700 per month, and site owners frequently describe Algolia's hosted entry point as painful once traffic grows — because usage is billed per request, and in as-you-type search each keystroke can count as a separate request, unexpected traffic (including bots) becomes unexpected cost. At the bottom, open-source engines are nearly free but cost you engineering time. Many small sites sit in the middle: they have outgrown a free tier but are not ready for a four-figure monthly bill or a DIY build. That middle is exactly where a flat-price widget fits — Achla is a fixed $15 or $39 per month with an included query volume and capped overage, so the bill does not surprise you. See our Algolia alternative and AddSearch comparison for the head-to-head detail.

Achla is deliberately built for the SMB middle, not to replace every tool above. It is a managed answer widget that installs as one <script> tag, crawls your site, and returns a written answer grounded in your content with citations — refusing to answer when the content does not support one. Pricing is flat ($15 or $39 per month), there is no LLM key to manage, and it answers in 8 languages out of the box. It is the right choice for an owner who has outgrown a free plan but does not want a $1,200-a-month contract or a self-hosted build. It is not the right choice if you need sub-50ms faceted product discovery at massive scale (look at Algolia), or if you want to own and host every layer yourself (look at Meilisearch or Typesense). For documentation-heavy sites, our documentation search guide covers the ticket-deflection angle. Pick the tool that matches your job.
