Overview
Chattermill is a London-based Voice of Customer analytics platform. It brings customer feedback from surveys, review sites, support conversations, social media and calls into one place. Its proprietary Lyra AI tags every piece of feedback with themes and topic-level sentiment, and Impact Analysis links those themes to movements in NPS, CSAT and similar scores. The platform also offers precision insights, dashboards and reports, and anomaly detection that sends alerts to Slack, email or Jira. Newer AI features include Lyra Agent, which was in early preview and answers questions with charts and linked customer quotes, and Proactive Insights, which flags spikes and emerging issues on its own. A read-only MCP server lets assistants such as Claude, ChatGPT and Cursor query Chattermill data. The integrations page lists about 100 connectors, including Zendesk, Intercom, Gorgias, Qualtrics, Medallia, Trustpilot, the App Store, Snowflake, Databricks and Gong, plus a REST API and CSV upload. The product is built for large B2C brands such as Uber, HelloFresh, Booking.com and E.ON Next. Chattermill itself says it is a poor fit for companies with fewer than about 5,000 feedback items a month. Pricing is quote-only. Plans are priced on integrations and monthly data credits rather than seats, and every plan includes unlimited users. Vendr transaction data puts the average contract at about 64,000 USD a year. The main limitation is the setup effort: reviewers and competitors say taxonomy tuning and dashboard configuration take analyst time, and occasional users can find the interface busy.
Our Rating
Who Chattermill is best for
Best software for EnterpriseGood fit
Chattermill is built for high-volume enterprise brands such as Uber, Booking.com and Tesco, and says it fits teams with more than 5,000 feedback items a month.
It connects to 17 support tools, including Zendesk, Intercom and Gorgias, and analyses contact reasons and frontline performance.
It has connectors for returns and post-purchase tools such as Loop Returns and Recharge, plus e-commerce customers like HelloFresh and Footasylum.
Less suited
It sends alerts to Jira and connects through MCP to Linear and Notion, but a competitor analysis frames it mainly for CX teams measured on scores.
Reviewers say the enterprise-level price is steep for mid-sized companies.
Contracts average about 64,000 USD a year, and the vendor says it is a poor fit below about 5,000 feedback items a month.
Pros & Cons
Pros
- Very broad connector library: about 100 integrations across support desks, survey tools, review sites, social networks, data warehouses and AI agents.
- Impact Analysis ties feedback themes directly to NPS and CSAT movement, which G2 reviewers praise for making the insights clear.
- No per-seat fees, so large organisations can roll it out widely; Uber reports more than 400 users.
- Strong compliance credentials: SOC 2 Type II and ISO 27001 certification, automatic PII redaction at ingestion, and UK/EU data residency by default with a US option.
- Read-only MCP server lets teams query feedback data from Claude, ChatGPT or Cursor.
Cons
- No public pricing; Vendr data puts the average contract at about 64,000 USD a year, which is out of reach for small teams.
- G2 reviewers find the interface busy and hard to learn for occasional users and newcomers, and some report filtering problems.
- Theme models need analyst tuning at the start, so rollouts can stall without a dedicated owner.
- Some users report limited flexibility in exports, dashboard customization and bespoke reporting.
- Lyra Agent was listed as an early preview rather than generally available.
