EBITDAI

    AI for Excel: the Excel AI add-in for Windows, Mac and the web

    Up to 40x more usage than Claude and ChatGPT

    EBITDAI natively runs on DeepSeek, Kimi, Gemini and Meta Muse, allowing best-in-class performance at much higher usage limits than Claude and OpenAI. For the same price as their lowest tier subscriptions, EBITDAI delivers enough usage to handle most workloads.

    From $5/month · No 5-hour windows, no weekly lockouts · Excel on Windows, Mac, and the web

    45 seconds: what EBITDAI does, start to finish.

    Google Sheets

    Coming soon!

    EBITDAI is bringing the same AI models and workflows to Google Sheets as a Google Workspace add-on: the identical agent, running in a sidebar beside your spreadsheet. It reads and writes the sheet you have open, builds and edits models the same way it does in Excel, and signs in with the same account.

    The Google Sheets add-on is built and working end to end. It is not yet published in the Google Workspace Marketplace; until then, EBITDAI runs in Excel on Windows, Mac, and the web.

    Dramatically more tokens per dollar than the big-lab add-ins

    EBITDAI runs on DeepSeek, Kimi, Gemini and Meta Muse, whose tokens cost roughly 4-75x less than Claude API rates. This translates to a generous monthly allowance included in each subscription, as well as the ability to pay as you go without breaking the bank. Prefer flat-rate all-day modeling? EBITDAI is also the only add-in that runs on a Kimi Code subscription. Combined with a Pro subscription, this produces the single best value of any Excel agent. The bars below show what each plan's included allowance buys in complete model builds on the model each bar names: the flat-rate Kimi Code bar on top, then Meta Muse Spark 1.3, the cheapest model in the plans, or DeepSeek V4.1 Flash. See the math: DeepSeek in Excel · Kimi in Excel.

    Included usage by subscription: complete model builds per month

    Pro + your Kimi Code subscription EBITDAI $15/mo + Kimi $19/moup to 4,400 builds
    Pro on Meta Muse (cheapest model) EBITDAI $15/moup to 1,354 builds
    Pro on DeepSeek V4.1 Flash EBITDAI $15/moup to 663 builds
    Lite on Meta Muse Spark 1.3 EBITDAI $5/moup to 180 builds
    Claude Pro $20/mo, on Fable 5up to 85 builds, est.
    ChatGPT Plus $20/mo~40 agentic tasks, shared pool

    The top bar is the flat-rate path: Pro's $15/month plus a $19/month Kimi Code subscription, $34 all-in, buys up to 4,400 builds on Kimi k3. Under it are the two Pro bars, the same monthly allowance, 7.5x more usage than lite, priced two ways: on Meta Muse Spark 1.3, the cheapest model in the plans, it buys 1,354 builds, and on DeepSeek V4.1 Flash it buys 663. Lite's allowance, 100x more usage than free, buys 180 on Meta Muse Spark 1.3, the only model Lite runs, and Claude Pro is shown at its best case of 85. Those are the chart's own numbers, and they are no longer turned into a multiple against Claude or ChatGPT: the old per-dollar multiples were measured against a monthly allowance this pricing retired, so they went with it. Every EBITDAI plan is one simple monthly pool with no 5-hour windows or weekly lockouts, so a single deadline sprint can use as much of it as you like, and on Pro your own DeepSeek key builds about 880 complete models for $10, about a cent each, working the minute you create the key.

    Built from our published benchmark: one complete model build costs $0.0113 at published DeepSeek V4.1 Flash off-peak prices and $0.0055 on Meta Muse Spark 1.3's Contributor rate card, both priced 2026-09-10; Claude Pro and ChatGPT Plus figures are third-party estimates. Every EBITDAI bar is a plan's monthly allowance divided by that per-build cost, at the allowances the plans publish today: Pro at 7.5x more usage than lite, and Lite at 100x more usage than free. The 4,400 bar is the Kimi Code path, where EBITDAI's $15/month carries the plan and you supply a $19/month Kimi Code account on top of it, $34 all-in; on the Free, Lite and Pro plans by themselves there is no second AI account or bill at all. The Kimi Code figure is a third-party estimate, on the benchmark's one-window-per-working-day math, since Kimi publishes no exact quota.

    Usage so simple there's nothing to decode

    No opaque quotas, no rationing math, no surprise walls. You always know where you stand: your remaining usage shows right in the pane.

    No 5-hour windows. No weekly lockouts.

    Your usage is one monthly pool. Work in bursts, model all night before a deadline, spend it however you like. Nothing cuts you off mid-task and tells you to come back later.

    Hundreds of model builds a month, on every plan.

    Pro's $15/month allowance builds 1,354 complete models a month on Meta Muse Spark 1.3, the cheapest model in the plans, and 663 on DeepSeek V4.1 Flash, and Lite's allowance, 100x more usage than free, builds 180 on Meta Muse Spark 1.3, the only model Lite runs. For scale, that is against about 40 for a $20 ChatGPT Plus plan and 85 in Claude Pro's best case, dedicated to Excel and not shared with chat and coding. It refreshes every month, automatically.

    Want more? Top up in a minute.

    Buy extra usage on the spot ($5, $10, or $25, right in the pane) at a far lower price than Claude's extra usage. It never expires, and on Claude the alternative is a $100/month plan.

    Feature parity, at a fraction of the AI cost

    All five tools work agentically in a spreadsheet. The differences are what a token costs, how hard the meter caps you, and the modeling layer on top.

    Your workbook, your business.

    EBITDAI never stores your prompts or workbook content on any paid plan. On the free plan, conversations are logged and read by our team to improve the product. The exact data path (what passes through our relay, what goes where, per plan and per provider) is documented in full on the security page.

    Want to run on your own AI account instead? EBITDAI Pro runs EBITDAI on your own Kimi, DeepSeek or Gemini API key, and a $19/month Kimi Code subscription slots in the same way. Free and Lite run on Meta Muse Spark 1.3 Contributor, so they do not take your own key.
