Predictions from the tables you already keep.

Upload a spreadsheet of customers, loans, machines or orders. The Workbench runs today's tabular foundation models and gradient-boosted trees against your own history, validates them the way your reviewers expect, and shows which one to trust.

Free for a month: five runs, up to 50,000 rows each. No card, no installation.

See a run

Two runs, start to finish.

Two seeded projects, recorded end to end. A table like yours runs the same way.

After one run

What you leave with.

Every run produces the same four things, on your own table, inside your own workspace.

Leaderboard

Your current approach is on the board

Every run scores a baseline, a plain regression, gradient-boosted trees and foundation models on the same time-based folds. The simpler model wins when scores are within one standard error.

Every row

A score and a range for every row

Yes/no questions get a probability with a calibration check. Numbers get an 80% range. Each row shows the strongest drivers behind it.

Decision

A threshold you can reason about

Move the cut-off and see approvals, expected misses and the business impact on your own base rate.

Monitoring

Watched from day one

The chosen model is frozen at a deployment date and replayed forward. Drift in any input raises a warning or an alert.

How a run works

One table in. Predictions out.

No feature pipeline to build and no model to configure. Bring the table, confirm three guesses, press Run.

  1. Bring one table

    One row for each thing you want a prediction for. The outcome you want to know as a column, blank where it is not known yet; those rows get predicted. An ID per row and a date if you have one, so every test trains on the past and scores the future.

  2. Confirm three guesses

    The Workbench proposes the target, the ID and the date column. Check them and press Run. Columns that look like personal data are flagged so you can drop them before anything is stored.

  3. Read the leaderboard, download the predictions

    Most runs finish in a few minutes. Every decision the feature screen made is listed, with the with-and-without comparison.

An illustration of what one scored row looks like: the probability, its range, the drivers behind it and a status. Switch the table to see the same format on a different question. All rows and scores here are synthetic examples; the real thing, on your own data, is in the Workbench.

Built for review

Evidence your reviewers already ask for.

Whether the reviewer is a bank's model-risk team or a COO, a run shows its work. We start with financial services, the strictest review there is.

Backtests

Validated on time, not on luck

Folds train on the past and score the future. A leakage test scrambles every row after the cut-off and checks that no feature changes.

Baseline

The baseline is always on the board

The naive answer, a plain regression and gradient-boosted trees sit next to the foundation models. Sometimes the simpler one wins. Then it wins.

Uncertainty

Ranges, calibration, drivers

80% ranges on numbers. Calibration curves on probabilities. The strongest drivers for each row, signed.

Monitoring

Watched after deployment

Population stability on every input, with warn and alert thresholds, and the score replayed month by month.

How every pilot runs
  1. Shadow mode

    The model scores live cases. Your current process keeps deciding.

  2. Side by side

    Both compared on the same cases.

  3. Validation sign-off

    Your reviewers check backtests, calibration and drivers.

  4. LIVE

    In production, with your current process as the fallback for rows flagged for review.

Results from the free month are for evaluation. Production use needs the review your field requires, such as a fair-lending or model-risk review, and that is what the pilot is for.

Foundation models that read your rows as context.

Prior-data fitted networks are trained once across millions of synthetic datasets. Shown a new table, they find the pattern in a single forward pass, with no training on your data and no model to maintain.

Your data

Nothing leaves our server.

Every model runs on our own machine. No row of your data goes to any outside service.

  • Upload

    Columns that look like personal data are flagged at upload, and you can drop them before anything is stored. The models do not need names, emails or ID numbers.

  • Access

    Only your workspace sees your projects. The sample projects are the one thing every workspace shares, and they use public or generated data.

  • Retention

    Files are kept for 30 days after the last run, or deleted the moment you press Delete. HTTPS on the way in, an encrypted disk on the server.

  • Pilots

    A pilot can run inside your own environment, with the same leaderboard, ranges and monitoring. Ask on the form.

Questions

What teams ask first.

Short answers to the questions that come up before the first upload. The guide inside the Workbench covers every screen.

Something else?hello@knoww.ai

One table, one row per thing, the outcome as a column, blank where it is not known yet. An ID for each row, and a date if you have one. CSV or Excel, up to 50,000 rows and 500 columns in the free month.

Where this is going

The table is the next frontier.

Today's tabular models read a snapshot. Knoww is building the one that reads a history.

Left: what a tabular foundation model reads today, one row as it stands. Right: what LTFM is built to read, every row as it changed, with the links between them.

In 2026 SAP bought the lab behind TabPFN and Nvidia bought the company behind the first relational foundation model. Both bets say the same thing: the valuable prediction problems in a business live in tables, and a model can be pretrained to learn them from the rows you hand it.

LTFM, the model Knoww is building, is a longitudinal tabular foundation model. It reads entities, their state and their history, so the same model answers questions about change. The Workbench is where that work meets real tables.
