### Seek AI

Free plan

Seek AI

4.5 /5 on G2 · 759 ratings, Jun 2026

Seek AI is a natural-language data analytics platform. It lets business users query enterprise databases by typing plain-English questions, which the platform converts into optimized SQL via its proprietary SEEKER-1 model. No coding is required, so analysts, ops managers, and executives can get answers directly from Snowflake, BigQuery, Redshift, Databricks, and Azure without waiting on a data engineer. The platform runs a multi-agent architecture that maps questions to a customer's specific database schema, applies reinforcement learning to improve accuracy over time, and delivers results with context. Users can interact through a web interface or through Slack and Microsoft Teams. The system achieved over 90% accuracy on Yale's Spider SQL benchmark, placing first on the leaderboard. It is SOC 2 Type I compliant and supports role-based access controls for enterprise governance. Seek AI was acquired by IBM to deepen its watsonx data intelligence offering and integrate the technology into the Watsonx AI Labs accelerator. The acquisition confirmed Seek's position as a serious enterprise-grade tool rather than a consumer experiment. Pricing is enterprise-only and negotiated through IBM's sales channels following the acquisition.

## How to choose AI research software

1. Match tool to source typeAcademic papers (PubMed, Semantic Scholar coverage): Elicit, Consensus, Scite, Undermind. Web + news + general knowledge: Perplexity, ChatGPT/Claude/Gemini Deep Research. Different sources, different tools.
2. Audit citation qualityHallucination of fake citations is the #1 risk in AI research tools. Tools that ground every claim in linked sources (Elicit, Consensus, Perplexity) outperform free-form LLMs. Always verify cited sources by clicking through.
3. Plan for the manual layerAI research accelerates the literature search but doesn't replace reading. Use AI for breadth (what exists, who said what); read source papers for depth and validation.
