Scentrail is a browser-based data exploration tool from D&AT Company Co., Ltd. It opens Excel, CSV and Parquet files (.xlsx, .xls, .csv and .parquet) and gives a quick overview of the structure and contents of the data. Its tagline, "Scent the trail," reflects the idea that the path of an analysis matters as much as the final chart.
The product has two parts. Source covers the file itself, including profiling, column types and values. Trail is where a person records the exploration, the analysis and the supporting evidence. Entries can be marked as a premise, observation, anomaly, question, insight, summary, action or memo, so a reader can later see why each step was taken.
After a file is opened, Scentrail detects encoding, checks column structure and infers data types, so users do not adjust each file's format by hand. The site says the columns selected when adding a source are processed in the browser and then stored on the server, while the original file is not kept. Deleting a source permanently removes its converted Parquet data.
Profiling covers the whole dataset rather than a sample. Missing values, distributions, skew, duplicates and data quality issues appear in one place. Automatic charts for composition, comparisons and trends give a starting point, and each can be opened in a Trail. Users can narrow the data to what matters and compare it in a chart, or lay a chart out over time to compare periods.
Beyond profiling and automatic charts, Scentrail includes a SQL editor where users explore the schema, write queries and get results. Query results can be saved as CSV or Parquet, and charts as PNG. Users can also download the schema, data profile and source data as Markdown and Parquet, then upload them to another LLM of their choice to keep asking questions.
Trails capture questions as they come up, and an overview page shows recent Trails, open questions and tasks. Past analyses can be revisited and continued with new files. Version history lets users compare changes and switch to the version they need, with 10 versions per source on paid plans. The site states that SQL is optional for basic exploration and note-keeping.
Scentrail is a browser-based data exploration tool that opens Excel, CSV and Parquet files, profiles them and builds automatic charts. Users record findings and questions in a Trail so the reasoning behind an analysis is kept.
Scentrail has a Free plan at $0, a Pro plan at $19 per month and a Team plan at $49 per month, all excluding tax. Team includes 3 members, and each additional member costs $9 per month.
Yes. The Free plan includes 3 sources, 3 Trails, 3 saved SQL queries, unlimited query runs and 1 workspace. The site says no credit card is required to start.
Scentrail supports .xlsx, .xls, .csv and .parquet files. The file size limit shown is an estimate based on the device and browser, so the real limit depends on the format and available memory.
No. Users can explore data and keep notes without writing queries. The SQL editor is available when someone needs to go beyond charts.
According to the site, the columns selected when adding a source are processed in the browser and then stored on the server. The original file itself is not kept.
The site says Scentrail goes beyond understanding data structure. Users can create charts and record questions and reasoning in a Trail, then use that context in future analyses.
Yes. Anyone in the same workspace can view every registered source and Trail, regardless of who created it. Edit and delete access is controlled by permissions.
