Ask, Answer, Act. In One Flow.
Power BI runs on imported models and report-bound AI, so users pause, switch interfaces, and start over. ThoughtSpot queries live data across every source and keeps AI, dashboards, and spreadsheets in one flow, so insights arrive when teams need them.
- From AI to dashboards and back.Ask in Spotter, drill into any visual, and keep asking.
- Live data, zero copies.Query unified data in real time, with no extracts.
- The full picture in one place.Analyze structured, unstructured, and web data together.
- Spreadsheets that write back.Edit in a spreadsheet UI and query the results with no analyst help.*
- AI context breaks.Moving from report AI to standalone Copilot loses the conversation.
- Live queries run slower.Power BI recommends import mode for speed.
- Structured data only.Unstructured analysis needs tools outside Power BI.
- Read-only BI.No native spreadsheet or writeback.
“Spotter makes it so much easier to run through a massive amount of data from thousands of reports over the last five years. Having this ability makes it possible to proactively identify opportunities to make improvements and potentially save a lot of money.”
Moa Eriksson, Head of Data and AI, Hemso
Trusted Answers. Beyond What Happened.
Copilot uses an LLM to interpret the semantic model, so even governed data can return different answers, and it stops at what happened. Spotter answers from one governed semantic layer, explains why a metric moved, and recommends what to do next.
- Trusted answers, every time.No LLM guessing at business logic.
- Every answer explained.Plain-language logic and patented search tokens that anyone can check.
- Why, what next, and what if.Find what drove a change, get recommendations, and explore outcomes.
- Deep analysis, no analyst.Forecasting, cohorts, and Python-powered analysis built in.
- Answers need checking.Copilot is non-deterministic, so analysts need to validate results.
- Limited explainability.Users see the fields Copilot picked, not its reasoning.
- Stops at what happened.Copilot doesn't explain metric changes or recommend next steps.
- Advanced analytics needs analysts.Forecasting and anomaly detection need analyst support.
“The biggest business impact for us was when the executive leadership can go and ask their own questions, find the problem, and find a solution for it, without having to wait for weeks and months to get a new report or a new data set prepared for them.”
AJ Rao, Director, Business Intelligence & AI, Intuitive Surgical
Scales With Your Warehouse.
Not Your Capacity Plan.
Not Your Capacity Plan.
As data and users grow, Power BI teams manage capacity, wait on queued queries, and fence in Copilot to keep answers reliable. ThoughtSpot queries the warehouse live, with no data copies or capacity to manage, and keeps performance and accuracy steady at scale.
- Scales on warehouse compute.Live queries with no extracts grow with demand.
- Optimized for efficiency.The semantic model reduces warehouse compute as users and queries grow.
- AI that holds up on complex models.Spotter uses governed context across complex data models.
- Capacity to manage.Teams tune Fabric or Premium capacity to avoid throttling.
- Queries queue up.DirectQuery slows as more users query at once.
- Complex models need AI guardrails.Analysts limit Copilot's context, add instructions, and configure verified answers.
“With ThoughtSpot, our Finance teams can deliver more detailed insights to leaders two days faster, allowing analysts to drive greater impact.”
