[01] Features

Everything you need to forecast.

From AI-powered data analysis to deep learning models, ForecastJedi brings professional forecasting to your spreadsheet.

AI Data Analysis

Our AI analyzes your data, detects columns, assesses quality, and recommends the best forecast configuration automatically.

Deep Learning

Our deep learning engine captures complex seasonal patterns, trends, and non-linearities that traditional models miss.

Smart Interpolation

Smart algorithms fill missing values intelligently using iterative edges-first approach. Up to 40% gaps handled.

Covariates

Include marketing spend, weather, events, or any external factor as covariates with the deep learning model to capture complex relationships.

Auto-Expiring Data

Your data is processed in-memory and job results auto-delete within 1 hour. Minimal OAuth scopes, TLS 1.3 encryption, GDPR compliant.

Confidence Intervals

Every forecast includes upper and lower bounds with configurable confidence levels, plus MAE and MAPE accuracy metrics written directly to your sheet.

[04] FAQ

Frequently asked questions.

ForecastJedi uses statistical models for fast synchronous forecasts (under 1 second) and advanced deep learning for complex patterns with seasonal trends and non-linearities. Missing values are filled automatically using smart interpolation with built-in outlier detection.
No. ForecastJedi processes your data in-memory and temporarily caches job results that auto-delete within 1 hour. We use minimal OAuth scopes (spreadsheets.currentonly) and only access the sheet you're working in. Your data is encrypted in transit with TLS 1.3 and our architecture is GDPR and CCPA compliant.
The free tier includes 3 forecasts per day and 10 per week. The Pro tier (€10/month) gives you 30 per day and 100 per week. Team (€90/month) provides 200 per day and 1,000 per week.
ForecastJedi accepts dates in any common format (YYYY-MM-DD, MM/DD/YYYY, DD/MM/YYYY, etc.) and supports daily, weekly, monthly, and quarterly frequencies. Our AI analyzer automatically detects date columns, value columns, covariate columns, date format, and data frequency from a sample of your data.
Yes. ForecastJedi supports multivariate forecasting with covariates. Include columns like marketing spend, weather data, promotional events, or economic indicators alongside your target variable. The AI analyzer will recommend which columns to use as covariates based on your data.
Accuracy depends on your data quality, history length, and the presence of clear patterns. ForecastJedi writes MAE and MAPE accuracy metrics to your sheet with every forecast, plus configurable confidence intervals (80%, 95%, or 99%). As a rule of thumb: more data, consistent frequency, and relevant covariates produce better results.
