Key differences
Power BI lists a free tier and ThoughtSpot does not.
Power BI has the lower starting price ($14/mo against $25/mo for ThoughtSpot). The cheapest plan rarely has the same limits or features, so compare plans before choosing on price.
Both are in our Data & Analytics category.
About each tool
ThoughtSpot
Natural-language analytics platform with Spotter AI agents for dashboards and answers. Essentials is $25 per user a month billed annually; a free trial is offered.
Who it is for
It suits teams that want search-style analytics on data kept in a warehouse, from small groups on Essentials (5 to 50 users) to larger organizations on Pro or Enterprise. A separate Embedded line, with a Developer plan, is aimed at teams that add analytics to their own applications.
Strengths
- The pricing page lists, for all tiers, AI agents for analytics, AI highlights and summaries, natural language search, AI-suggested questions, iOS and Android apps and row-level security.
- ThoughtSpot says it does not meter or charge for LLM tokens; platform use is governed by the subscription, such as queries or users. If you connect your own LLM provider, that provider's fees may apply.
- The pricing page lists live connections to data warehouses such as Snowflake and Databricks.
- Pro is listed for up to 1,000 users and up to 250M rows; Enterprise is listed with unlimited users and data.
- Enterprise adds a 1-hour support SLA, advanced data encryption, VPN and VPC support and a custom company URL, per the pricing page.
- Add-ons listed for lower tiers include Analyst Studio (data prep, mashups, modeling, SQL, R and Python analysis, in-memory cache) and an Unlimited Spotter add-on whose price is not shown.
Limitations
- Essentials is listed for 5 to 50 users and up to 25M rows, and Pro for up to 1,000 users and up to 250M rows. The German pricing page shows Pro as 25 to 1,000 users, so the minimum is unclear.
- Pro per-user includes Spotter AI agents limited to 25 queries a month per user. The pricing page shows an Unlimited Spotter add-on with no price.
- Usage-based Pro is described as $0.10 per credit on the English pricing page but as $0.10 per query on the German page. The docs say credits are consumed by searches, viewing or editing Liveboards and Answers, modeling, admin changes, Spotter use and Analyst Studio, but they give no credit allowances or price.
- Per-user prices are billed annually. Enterprise is custom-priced through sales, and the pricing page has no refund or cancellation terms.
- The pricing page gives no free trial length, and the Developer plan is listed both as free for 1 year and simply as free. The Spotter security and data-handling docs pages could not be read in full, so training and retention terms were not confirmed.
Power BI
Microsoft's BI platform with a free Windows Desktop app; Copilot needs paid Fabric or Premium capacity. Pro is $14 per user a month billed annually.
Who it is for
Microsoft's overview describes business users who view reports, report creators who build and publish them, administrators and developers who embed or extend it. Copilot in Power BI is aimed at organizations with paid Fabric or Premium capacity.
Strengths
- Microsoft says Power BI Desktop is free, runs on Windows 10 or later, and connects to more than 100 data sources.
- Microsoft lists a free account for creating reports; Pro adds publishing and sharing, and Pro and Premium Per User are sold self-service or through the Microsoft 365 admin center.
- The Power BI service lists workspaces, apps, scheduled refresh, email subscriptions, alerts, embedding, row-level security and sensitivity labels.
- Microsoft says viewers can read reports without per-user licenses on Premium P1 and above, and Fabric F64 and above.
- Microsoft's privacy page says Copilot data stays within the organization's tenant boundary, is not used to train foundation models, and prompts and responses are not stored after the session ends.
- Microsoft says tenant administrators can enable or disable Copilot in the admin portal, and lists separate tools for paginated reports and an on-premises Report Server.
Limitations
- Copilot in Desktop requires access to a workspace on paid Fabric capacity (F2 or higher), Premium capacity (P1 or higher) with Copilot enabled, or a Fabric Copilot capacity. Microsoft shows Copilot in Fabric under the Fabric capacity plans, not the free account.
- Pro lists a 1 GB model size, 8 refreshes a day and 10 GB native storage per license. Premium Per User lists a 100 GB model, 48 refreshes a day and 100 TB storage.
- Fabric capacity (pay-as-you-go or reservation) is priced separately and was not listed on the Power BI pricing page. A Pro license is still needed to publish Power BI content to Fabric, and Microsoft's page says prices may differ by currency, country and region.
