Best Voice AI for BigCommerce Stores (2026)
Six voice and chat tools that can be loaded through BigCommerce Script Manager, with notes on Stencil themes, checkout exclusion, free tiers and pricing.
Best voice AI for BigCommerce: tools that load through Script Manager
BigCommerce has no voice app we could confirm from vendor pages, but its Script Manager can load any hosted script on storefront pages, which suits AnveVoice, ElevenLabs, Vapi and Retell for voice and Chatbase or Tidio for chat. It works only on Stencil themes and should usually exclude checkout. Researched from the sources below on 2026-10-14. AnveVoice is our product and appears in this list. Other tools are described from their own websites, checked on 2026-10-14. We do not receive payment from any tool listed.
How we chose
We must be careful on this page. The vendor datasets we use do not describe BigCommerce-specific apps for these tools, so none is listed here because of a BigCommerce listing. Instead we picked tools whose own sites describe a script-tag or copy-and-paste embed, which is what Script Manager accepts. BigCommerce limits matter more than vendor features: Script Manager works only with Stencil themes, scripts on payment pages need integrity hashes, and a new script can take about 20 seconds to appear on a hosted storefront. Prices and facts were checked on 2026-10-14.
- A documented script-tag or embed route that fits Script Manager's footer placement.
- Browser voice for shoppers, weighted highest.
- Fit with BigCommerce's cookie consent categories, since scripts are labelled Functional or otherwise.
- A published price unit and a free way to test.
- Suitability for storefront pages rather than payment pages.
1. AnveVoice: a hosted tag that suits the Footer placement
The install guide for BigCommerce uses Script Manager: create a script, place it in the Footer, choose Storefront pages, set the category to Functional and paste the tag. Because the hosted file can change when AnveVoice updates it, we advise against pinning an integrity hash, which is also why we recommend keeping it off payment pages. Pricing as published: Free at $0 with 50,000 tokens and one bot; Growth $39 a month; Scale $129 a month. Limitations: our dataset records no BigCommerce app, the agent is website-only, and if a shopper declines the Functional consent category the button will not appear.
2. ElevenLabs Agents: voice widget, build-it-yourself
ElevenLabs describes a customizable widget for any website, and its docs say client tools can trigger UI events in the browser. A BigCommerce developer could use that to link the agent to category pages. Voice quality and the free 15-minute plan are its draws. Starter is $6 a month for 75 minutes, Pro $99 for 1,238 minutes, and extra minutes are $0.08 (2026-10-14). Limitation: no BigCommerce guide is published, and you must build any catalogue logic.
3. Vapi: script tag plus npm package
Vapi documents a script tag that loads a widget from a CDN and a Web SDK for custom UI. For a BigCommerce team with a Stencil developer, the SDK allows a styled button matching the theme. The hosting fee is $0.05 a minute and models and telephony are billed at provider cost; the Core plan is $29 a month (2026-10-14). Limitation: no free plan beyond $5 in credit.
4. Retell AI: shared agent for phone and web
Retell supports a Web SDK and an embeddable voice widget alongside phone numbers. A BigCommerce merchant that also takes order calls can run both from one agent definition. From $0.07 a minute with $10 in credit and 20 free concurrent calls; Enterprise starts at 50 or more concurrent calls (2026-10-14). Limitation: the cost components are itemised, so budget the total.
5. Chatbase: copy-paste agent trained on your content
Chatbase says you can embed with simple copy-paste code or publish with a click, and it lists Shopify and Zendesk channels. Its agents run actions such as order lookup and invoices. For BigCommerce, treat it as a generic embed. Hobby is $40 a month for 700 credits with a 7-day trial; Standard $150 with 4,000 credits (2026-10-14). Limitation: its listed actions are backend ones, and voice in the browser is not stated.
6. Tidio: lightweight chat, connects to a website
Tidio's setup notes say you connect Shopify, WooCommerce or your website, with nothing to install on your servers. For a BigCommerce shop, the website route is the relevant one. Free includes 10 seats and 50 billable conversations; Starter $24.17 a month (2026-10-14). Limitation: no BigCommerce integration is described, and voice is not mentioned.

Script Manager settings that decide the result
Choose Footer placement and the Storefront pages location, which covers all pages except checkout and order confirmation. The All pages option adds checkout, where BigCommerce expects integrity hashes, and where scripts render only if Optimized One-Page Checkout is enabled. The category you pick feeds the cookie banner. A voice assistant is an optional feature, so Functional is the closest fit, but shoppers who decline it will not see the button. Also remember that local Stencil CLI development does not render Script Manager scripts.
Honest caveats
If your storefront still uses the older Blueprint engine, none of this works until you move to Stencil. If you manage several storefronts, open Script Manager through Channel Manager for each one. And if voice is not essential, a plain chat tool will be simpler.
