ThoughtSpot vs Looker: what each is built for, and when neither fits

ThoughtSpot vs Looker compared: what each is built for, what it needs before the first answer, and a file-first option when neither fits.

The short answerBoth sit on a warehouse and rely on a modelled layer. ThoughtSpot's AI translates a question into search tokens from its Models; Looker's Conversational Analytics composes a query through LookML Explores. ThoughtSpot suits companies with a cloud data warehouse that want business users to self-serve answers in plain language; Looker suits organisations that want one governed set of metric definitions shared across teams and tools. When the need is one desk's question answered from the exports it already has, a file-first tool may fit better than either.

ThoughtSpot and Looker are both good at what they are built for. Both sit on a warehouse and rely on a modelled layer. ThoughtSpot's AI translates a question into search tokens from its Models; Looker's Conversational Analytics composes a query through LookML Explores. This guide sets them side by side, fairly, and ends with the case where a team needs neither.

How it gets data Primarily live query: ThoughtSpot Connections link to external warehouses and databases (Snowflake, Databricks, BigQuery, Redshift, Synapse, Oracle, SQL Server, Teradata and others) and query them directly; primary and foreign keys and joins are imported with the tables. Live query: Looker generates SQL from the LookML project and submits it to the customer's database connection (BigQuery, Snowflake, Redshift, PostgreSQL, SQL Server, Oracle and many other dialects). SQL Runner also allows direct SQL against those connections. Files and sheets now; scheduled delivery by API, S3, Azure, SFTP or email on Business; connections built with your team on Enterprise

AI Spotter uses a large language model to translate a natural-language question into ThoughtSpot search tokens derived from the data model, rather than writing free-form SQL; ThoughtSpot then generates database-specific SQL from those tokens. It relies on ThoughtSpot Models as its business glossary and learns from user feedback. Analyst Studio adds AI assistance for SQL, Python and spreadsheet data preparation. Conversational Analytics uses Gemini for Google Cloud to interpret a natural-language question, map it to fields in the LookML model, and compose a Looker query through the model's Explores rather than writing free-form SQL. It then analyses the query results to answer the question and can create visualisations. Administrators must enable the Gemini in Looker setting. The AI model chooses a measure and writes the explanation; our tools do the arithmetic and check every total
Published pricing Published: Essentials from $25 per user per month (billed annually, 5 to 50 users, up to 25M rows); Pro from $50 per user per month (billed annually, up to 1,000 users and 250M rows, including Spotter at 25 queries per user per month); Enterprise and Embedded are custom-priced. A Developer tier is free for one year (10 users, 25M rows). ThoughtSpot states it does not meter or charge for LLM tokens on paid plans. Platform editions (Standard, Enterprise and Embed) and user licences (Developer, Standard and Viewer) are sold on annual commitments priced through Google Cloud sales; no list prices are published. Conversational Analytics is metered in data tokens, with monthly allowances included per platform tier (for example 60M input and 1.2M output tokens on Standard); overage is listed at $3.00 per 1M input and $20.00 per 1M output tokens, though Google states billing is not yet enforced during a promotional period. Data Studio (formerly Looker Studio) is free, with a paid Pro tier offering a 30-day trial. Three tiers on one sheet, shared in a conversation

ThoughtSpot in brief

ThoughtSpot is a search- and AI-led analytics platform that lets business users ask questions of their data in natural language and build interactive dashboards, called Liveboards. Its AI analyst, Spotter, answers questions using the business context defined in ThoughtSpot Models. Analyst Studio adds SQL, Python, R and spreadsheet-style data preparation for analysts in the same platform.

  • ThoughtSpot was founded in 2012 by Ajeet Singh and Amit Prakash and is based in Mountain View, California.
  • ThoughtSpot acquired Mode Analytics on 26 June 2023 for $200 million in cash and stock.
  • ThoughtSpot introduced its Spotter natural-language feature in November 2024.
  • ThoughtSpot's Essentials plan starts from $25 per user per month and Pro from $50 per user per month, both billed annually.

Looker in brief

Looker is Google Cloud's enterprise business intelligence platform. Data teams describe their database in LookML, Looker's modelling language, and Looker then generates SQL from that model and runs it against the connected database to power Explores, dashboards, scheduled deliveries and embedded analytics. It is separate from Google's free report builder, formerly Looker Studio and now called Data Studio.

  • Looker was founded in 2012 in Santa Cruz, California by Lloyd Tabb and Ben Porterfield.
  • Google announced its $2.6 billion acquisition of Looker on 6 June 2019 and completed it in February 2020.
  • Looker's documentation describes it as a tool that generates SQL queries from a LookML project and submits them against a database connection.
  • Looker platform editions are sold on annual commitments through Google Cloud sales, with no published list price.

Where ThoughtSpot fits best

  • Companies with a cloud data warehouse that want business users to self-serve answers in plain language.
  • Data teams that want a governed semantic model behind natural-language search.
  • Product teams embedding analytics into their own applications.

Where Looker fits best

  • Organisations that want one governed set of metric definitions shared across teams and tools.
  • Companies with a SQL data warehouse, particularly BigQuery users already on Google Cloud.
  • Product teams embedding governed analytics into customer-facing applications.

Where they differ

Data

ThoughtSpot. Primarily live query: ThoughtSpot Connections link to external warehouses and databases (Snowflake, Databricks, BigQuery, Redshift, Synapse, Oracle, SQL Server, Teradata and others) and query them directly; primary and foreign keys and joins are imported with the tables.

Looker. Live query: Looker generates SQL from the LookML project and submits it to the customer's database connection (BigQuery, Snowflake, Redshift, PostgreSQL, SQL Server, Oracle and many other dialects). SQL Runner also allows direct SQL against those connections.

AI

ThoughtSpot. Spotter uses a large language model to translate a natural-language question into ThoughtSpot search tokens derived from the data model, rather than writing free-form SQL; ThoughtSpot then generates database-specific SQL from those tokens. It relies on ThoughtSpot Models as its business glossary and learns from user feedback. Analyst Studio adds AI assistance for SQL, Python and spreadsheet data preparation.

Looker. Conversational Analytics uses Gemini for Google Cloud to interpret a natural-language question, map it to fields in the LookML model, and compose a Looker query through the model's Explores rather than writing free-form SQL. It then analyses the query results to answer the question and can create visualisations. Administrators must enable the Gemini in Looker setting.

What each needs before the first answer

ThoughtSpot:

  • A cloud data warehouse or database holding the data.
  • ThoughtSpot Models built by a data team to define joins, columns and business terms.
  • Administrators to manage connections, users and permissions.

Looker:

  • A SQL database or warehouse holding the data.
  • LookML developers to model tables, joins and measures before business users explore.
  • Looker administrators to manage connections, users and, for AI features, the Gemini in Looker setting.

When neither fits

Both assume a team that will build and maintain a model of the data before questions get answered. Some teams have a narrower need: one desk, one recurring question such as "what is driving my costs" or "where is my revenue coming from", and exports that already exist. For them, Covirage reads those files, answers the question with a bridge that sums to the change, and is set up for them within a week. The AI model chooses the measure and explains it; our tools do the arithmetic.
