Sourcetable

What is Sourcetable?

Sourcetable is a browser-based AI spreadsheet that turns plain-English requests into formulas, charts, cleaned tables and written analysis. The company calls it the world’s smartest spreadsheet and aims it at analysts, operators and finance teams. You load a file or connect a database, then chat with an AI assistant that edits the sheet for you. Behind the assistant, Sourcetable switches between models from OpenAI, Anthropic, Meta, DeepSeek and Hugging Face, and it can also run Python and SQL on the same data.

Sourcetable is based in San Francisco and was co-founded by chief executive Eoin McMillan and chief technology officer Andrew Grosser. Unite.AI reported a $4.3 million seed round in March 2025, backed by Bee Partners and angel investors including Hugging Face’s Julien Chaumond, plus Preston-Werner Ventures. The product is live and actively sold in October 2026, with a free tier, two paid plans and a 50% discount for students and faculty.

Key Features

• AI spreadsheet assistant: Sourcetable answers questions about your data in plain English and writes the result straight into the sheet. You can ask for a pivot, a summary or a trend explanation without building formulas, and the assistant explains what it changed.
• Formula and autofill help: Sourcetable generates spreadsheet formulas from a description and fills columns with its magic autofill feature. This helps users who know the outcome they want but not the exact function syntax, and it cuts time spent debugging nested formulas.
• Charts from prompts: The assistant builds charts and graphs from a single request, such as revenue by month or churn by plan. Futurepedia also lists chart automation as a core feature, which suits quick reporting where design control matters less than speed.
• Data cleaning: Sourcetable cleans and restructures messy data using AI, standard formulas or Python code. Typical jobs include removing duplicates, splitting columns and standardising dates, which usually take the longest in manual spreadsheet work.
• Python and data science toolkit: Paid plans run Python with NumPy, Pandas, SciPy, Scikit-learn, StatsModels, Matplotlib, Plotly and Seaborn inside the workbook. Analysts can mix spreadsheet cells with regression models or custom plots without switching to a separate notebook.
• SQL editor and query builder: The Pro plan adds an SQL editor and query builder for connected databases. You can pull live rows from Postgres, MySQL, BigQuery or DuckDB, then let the AI assistant analyse the results in the grid.
• 30+ data connectors: Sourcetable connects to more than 30 sources, including Postgres, Supabase, Stripe, Notion, Facebook Ads, GA4 and Robinhood. It also imports Excel, CSV, TSV, PDF and JSON files of up to 10GB, according to the official site.
• Deep research and agents: Sourcetable offers deep research on Pro and advanced agent capabilities on Max for multi-step work. The company says the assistant can enrich data with web research, which helps when a sheet needs outside facts added to each row.

Pros

• Generous free tier: Sourcetable’s free Regular plan includes the AI assistant, smart formulas, data cleaning and connector access with 50 credits a month. That lets you test it on real files before paying anything.
• Low barrier for non-coders: G2 reviewers say the spreadsheet-like layout feels familiar and the AI makes analysis more intuitive. Business users can get charts and summaries from plain-English questions rather than learning Python or advanced Excel.
• Strong data connections: Direct links to databases, payment, analytics and ad platforms mean less copying and pasting between tools. G2 reviewers single out the breadth of integrations as one of the main reasons they chose Sourcetable.
• Python and SQL in one place: Paid plans combine a grid, a Python toolkit and an SQL editor in one browser workspace. Analysts who switch between spreadsheets and notebooks can keep the whole workflow in a single file.
• Security credentials: Sourcetable says it meets SOC 2 Type 2, HIPAA and PCI standards, in its cloud or on-premises. That matters for finance and healthcare teams that cannot upload sensitive data to unvetted tools.
• Education discount: Students and faculty get 50% off the Pro and Max plans, according to the pricing page. The company also says it is used at Stanford, Oxford, Harvard and Peking University, as reported by Unite.AI.

Cons

• Credit-based usage: Every plan runs on monthly credits, and heavy users may need to buy top-ups costing $10 to $200. Budgeting is harder than with a flat licence, especially for teams running long agent or research tasks.
• Limited visual customisation: Several G2 reviewers say chart styling and customisation options need work. If you need presentation-ready dashboards with tight brand control, you may still finish visuals in another tool.
• Slower on huge datasets: One G2 reviewer reported slowdowns when working with very large datasets. The 10GB file limit is high, but performance can vary, so test with your biggest real file before moving a team across.
• Gaps in advanced statistics: G2 reviewers mention missing sophisticated statistical functions and complex formula features. Power users may fall back on the Python toolkit, which sits behind the paid plans.
• Smaller user community: Sourcetable lists 12 reviews on G2, far fewer than mainstream spreadsheet software. One reviewer notes that colleagues unfamiliar with the platform made collaboration harder, so expect some onboarding effort.

Who is Using Sourcetable?

• Data analysts: Query, clean and chart data without switching tools.
• Finance teams: Build models, forecasts and portfolio analyses.
• Operators and marketers: Pull Stripe, GA4 and ad data into reports.
• Students and researchers: Analyse datasets with a 50% education discount.

Pricing

Sourcetable is freemium, with a free Regular plan and paid Pro and Max plans billed per user each month (official prices, October 2026).

Futurepedia still lists a $20 Pro plan, which no longer matches the official pricing page. Credit allowances and plan names have changed before, so check the live pricing page and your usage history before committing a team.

What Makes Sourcetable Unique?

Multi-model AI sitting directly inside a spreadsheet grid is the core difference. Rather than bolting a chatbot onto Excel, Sourcetable routes each request to models from several providers, then writes formulas, charts or Python output into the same workbook. Live connectors to databases, Stripe, GA4 and ad platforms mean the data stays current instead of being exported and pasted. Few AI spreadsheet rivals combine a grid, an SQL editor, a Python toolkit and SOC 2, HIPAA and PCI claims in one browser product.

Compatibilities and Integrations

• Platforms: Web app that runs in a modern browser, with cloud or on-premises deployment mentioned by the company.
• Databases: Postgres, MySQL, BigQuery, DuckDB and Supabase through built-in connectors.
• Business apps: Stripe, Notion, Facebook Ads, GA4 and Robinhood among more than 30 sources.
• Files: Excel, CSV, TSV, PDF and JSON imports of up to 10GB.

How We Rated It

Summary

Sourcetable suits analysts, finance teams and operators who want to question live business data in plain English without leaving a spreadsheet. The free plan is enough to judge it, and Pro at $29 a month adds the Python and SQL tools most power users need. The main limitation is credit-based usage, which can make heavy months costly. Before upgrading, run your largest real dataset through the free plan and note how many credits a typical task uses.
