DataLens vs Obviously AI

DataLens reads CSV files in a browser, profiles their columns, and turns the analysis into an interactive report. It accepts drag-and-drop multi-file imports and clipboard pastes, and detects numeric, categorical, and datetime columns. Its eight chart types are bar, line, pie, donut, scatter, radar, histogram, and box plot. Pearson correlations appear in a heatmap; text insights can surface outliers, trends, top-k segments, and cross-correlations. Natural-language queries are supported, and an assistant can connect to Ollama, OpenRouter, Groq, or an OpenAI-compatible endpoint. The site says CSV data stays in the browser, while AI requests go from the browser tab to the configured provider. DataLens can run offline without installation or a backend, either in a browser or from a local HTML file or HTTP server. The maker describes CSV uploads up to approximately 50 MB. Reports export to PDF, and filtered data can be downloaded as CSV. The interface is available in French and English. DataLens is free and open source under the MIT License.

Obviously AI is a freemium, web-based no-code tool for turning structured data into predictive models. Listed model uses include classification, regression, and time series prediction. Models can be published as instant web apps with shareable dynamic links, or connected through real-time REST APIs that send predictions to tools such as Power BI and Looker. Automatic model monitoring and Zapier if-this-then-that automations are also described. Integrations include Amazon Redshift, Google BigQuery, Google Drive, HubSpot, Shopify, Snowflake, Tableau, and Zapier. A structured dataset is required; the documentation recommends at least 1,000 rows and 5 columns. CSV is the listed import format, with uploads up to 10 MB. The Free plan costs nothing and includes 1,200 predictions, one user seat, unlimited models, 1M rows of training data, CSV-only data, and limits of 10,000 data rows. Obviously AI is based in San Francisco. Security information lists SOC 2 Type II, GDPR data-retention compliance, HIPAA compliance, TLS in transit, and AES-256 at rest.
