Features

Everything you need to make sense of free text.

Astral is built around the workflow analysts actually use — upload, cluster, refine, share — not the one a notebook tutorial assumes.

CSV in, clusters out

Drop a CSV or Excel file. Pick the column you care about. Astral handles the rest — embeddings, clustering, labeling, hierarchy.

Auto-labeled topics

Every cluster gets a concise, human-readable label generated from its contents — no manual coding marathon.

Drill, merge, refine

Kanban, table, and umbrella views. Merge similar themes, split mixed ones, and relabel with one click.

Insights across segments

Bring metadata columns along for the ride. See which topics dominate which segments, with live charts.

Custom prompts

Summarize, extract quotes, suggest actions — run your own LLM prompts against any cluster.

Your data stays yours

Per-workspace isolation, granular member roles, and no training on your data — ever.

How it works

From spreadsheet to insight in three steps.

  1. 01

    Upload your data

    CSV, Excel, or paste. Astral previews columns and lets you mark which one to analyze.

  2. 02

    Run clustering

    We embed every row, cluster, and label the groups automatically. A few hundred rows takes under a minute.

  3. 03

    Explore and share

    Browse themes in kanban, table, or umbrella view. Drill into individual responses. Invite teammates.
