Features
The whole workflow, not just the model.
Astral is the bit between "I have a spreadsheet of free text" and "I have a slide that changes a decision." Every feature exists so that journey takes minutes, not weeks.
Ingest anything text
Astral works on free-text data — wherever it lives, however messy it is.
CSV and Excel upload
Drop a file, preview columns, pick what to analyze. Handles UTF-8 and the kind of garbled headers real spreadsheets ship with.
Multi-column workflows
Mark the column you want analyzed; everything else stays as metadata you can segment on. No copy-paste between sheets.
Metadata-aware
Bring along grade, segment, source, NPS — any column tags rides alongside the clusters so insights respect your taxonomy.
Clustering you can actually use
Embedding, clustering, labeling, hierarchy — every step is fast, repeatable, and editable.
Three views of the same data
Kanban for triage. Table for export-friendly review. Umbrella for high-level themes that roll up specific clusters.
Auto-labeled, editable
Every cluster gets a short, human-readable label. Don't like it? Click to relabel. Mass-rename via prompt.
Merge and split, no notebook
Two themes are really one? Merge. One cluster is mixed? Split. The state of the analysis stays consistent.
Ask anything, learn faster
Cluster output is the start, not the end. Run custom prompts on any group of responses.
Custom prompts
Save and reuse prompts: summarize, find insights, pull representative quotes, suggest actions. Apply to any cluster or your whole project.
Drill to individual responses
Click into any cluster to see the underlying rows. Every insight is traceable to source data.
Workspace-wide insights
Compare distributions across projects. See how themes shift quarter over quarter, segment by segment.
Built for teams
Astral is multi-user out of the box. Invite teammates, scope access, ship findings.
Workspaces and roles
Group projects under a workspace. Invite members as editors or viewers. The right people see the right data.
Live, shareable links
Every project has a stable URL. Share with a teammate; updates show up in real time. No exports to email around.
Segment analytics
Compare topic distribution across cohorts in one click. Surface which segments are driving which themes.
Trustworthy by default
Your data stays yours. No surprise training, no opaque retention.
Per-workspace isolation
Tenant data is scoped at the workspace level. Members of one workspace can't see another's projects, ever.
Auth and SSO via Clerk
Social, magic-link, password, or SSO on the Business tier — Clerk-managed and standards-compliant.
No training on your data
LLM calls go through no-training, zero-retention enterprise endpoints. Your content is never harvested.
See it on your own data.
Free tier covers up to 1,000 rows — enough to evaluate end-to-end.
