Bring what you have
Spreadsheets, exports, JSON or public sources. Vanessa reads the schema, types and gaps first.
Local-first analytics workspace
Your data.A clearer dimension.
An intelligent workspace for the questions that matter. Bring your data, follow the evidence, and turn complexity into your next clear move.
Or drop a CSV, Excel or JSON file on the box. Files are read in this browser and never uploaded.
How it works
See it on demo data
From raw files to a decision you can defend.
Vanessa plans the work, runs Signal Noir’s own tools on your data and shows every step, so you can check it rather than trust it blindly.
Vanessa runs the plan
Validation, cleaning, joins and the right analysis for the question, all shown step by step.
Audit every answer
Each finding records its source, rows, filters, calculation and method.
Leave with something useful
Dashboards, reports, decisions and follow-up tasks accumulate in your project.
What people use it for
Ask for the outcome, not the tool.
AI with evidence
Never accept an answer you can’t audit.
Vanessa’s numbers come from deterministic calculations on your rows, not from a language model guessing. Open the evidence on any finding to see exactly which rows, filters and formula produced it. If something wasn’t calculated, Signal Noir says so.
Where your project lives
The toolkit underneath
Browse all tools
Serious tools, whenever you want them.
SQL, significance tests, fuzzy matching, joins, dashboards and developer utilities. Every tool works on its own, free, in your browser.
One Signal Noir, shaped to the job
Free, local, and only as complicated as your work needs.
Everything here is free and works without an account. When several people share an install, an organization can group them into teams and give each team an access profile, so the interface shows the part of Signal Noir that belongs to their job. Nothing is sold and nothing is locked behind payment.
