Ajelix

AI toolkit for spreadsheets + BI

Ajelix bundles 17 AI tools — formula generation, VBA, Google Apps Script, template and report generation, an AI data analyst, and a full BI dashboard platform. Formula Foundry does one thing and does it deeply: a formula IDE for Excel and Google Sheets that writes, fixes, explains, and reuses formulas — with a real editor, global variables, and a free in-browser playground.

The context worth knowing

Ajelix is a capable, fast-moving AI suite. If you want a single tool that touches formulas, macros, scripts, translation, reports, and dashboards, its breadth is real — and so is its price ladder, which climbs steeply as usage and resources grow. Formula Foundry is deliberately narrower: it's a workspace for the formula itself, with a multi-line editor, @@variables, a reusable snippet library, and the same experience across Excel and Google Sheets. Deliberately not a do-everything AI wrapper.

If you're choosing between them, it's breadth versus depth: a wide AI toolkit that also writes formulas, or a focused environment built around how formulas actually get written, reused, and maintained.

Where Formula Foundry wins

Depth on the one job that runs your model

Ajelix spreads across many AI tasks. Formula Foundry puts all of its weight on the formula — the editor, the variables, the reuse, the maintenance.

A real editor, not a generate-and-paste box

Multi-line, syntax-highlighted, bracket-matched, auto-indented, with AI explanations inline. Most AI tools — Ajelix included — hand you a formula to copy out. Formula Foundry gives that formula a home where you can read it, refactor it, and debug it when it breaks months later.

@@Variables — change one value, update 500 formulas

Define @@DiscountRate, @@HeadcountTarget, @@FXRate once and use them across every formula in your workbook. Update one value and every dependent formula follows. It's the single feature no broad AI toolkit replicates — because it's about managing formula logic, not generating one-off outputs.

Excel and Sheets, and a translator between them

The same editor, snippets, and variables work in both Excel and Google Sheets, and the Excel-to-Sheets translator converts formulas across syntaxes automatically. If your work straddles platforms or inherits an Excel model, that's a workflow Ajelix's tool catalog doesn't cover.

Flat, predictable pricing

Ajelix's plans climb steeply with usage and compute — roughly $20 to $200 a month across tiers. Formula Foundry is flat: free to start forever, Pro at $19/month ($15/month billed annually), Business at $29/seat/month ($24/seat annually). You know the bill before you start.

Where Ajelix wins

When Ajelix is the better choice

Ajelix is a genuinely broad, capable suite. Here's when its range beats our focus — honestly.

  • You need code, not just formulas. Ajelix generates VBA macros and Google Apps Script, not only spreadsheet formulas. If you automate with scripts, that's real ground Formula Foundry doesn't cover.

  • You want a full BI and reporting platform. Ajelix includes dashboards, data sources, an AI data analyst, and report generation. Formula Foundry doesn't do dashboards or visualization — if BI is the goal, Ajelix is the broader tool.

  • You want many AI tools under one roof. With 17 tools — template generators, translators, an AI data analyst, and more — Ajelix is a Swiss-army knife for spreadsheet AI. If you'd rather one subscription cover lots of tasks, breadth is the win.

  • You translate spreadsheets or generate templates. Ajelix's translation and template-from-a-prompt tools are handy one-offs that Formula Foundry doesn't try to do.

We’d rather you pick Ajelix for the right reason than Formula Foundry for the wrong one.

  • You move formulas between Excel and Google Sheets and want a translator
  • You want flat, predictable pricing and a free plan that never expires

Less surface area,
more depth where it counts.
