SheetAI Review 2026: Pricing, Features, Pros & Cons
SheetAI puts AI inside Google Sheets as formulas rather than as a chat window you copy in and out of. The headline finding of this review is a pricing one: the bring-your-own-key tier is free forever and is not crippled — the $12 and $29 plans sell hosting and key management, not capability. Here is what that means for what you should actually pay.
Quick Verdict
Best for: Anyone who already works in Sheets and wants AI to behave like a formula — fill-down, ranges, recalculation. Start on BYOK; it is the whole product at your provider's cost. Move to Pro only if you want bulk Replicate media jobs or cannot hold an API key. Starter's ~500 runs a month is the tier most likely to disappoint, because spreadsheet work is exactly the shape that blows through 500 calls in an afternoon.
What SheetAI Actually Is
SheetAI is a Google Workspace add-on that exposes AI as spreadsheet functions. The =SHEETAI family takes the contents of other cells as inputs and returns generated text, summaries, classifications or extracted fields into the cell you wrote it in. A sidebar formula generator lets you describe the formula you want in plain English. A Replicate integration generates images, video and music in bulk from a column of prompts.
The distinction that matters is functions versus panels. Plenty of tools bolt a chat sidebar onto a spreadsheet; you paste data in, paste results out, and nothing recalculates. Because SheetAI is a function, it fills down a column, accepts ranges, and updates when its inputs change — which is the only reason to want AI in a spreadsheet rather than in a browser tab next to it.
The pricing model is the other distinctive thing. Most add-ons in this category meter the capability. SheetAI meters the hosting: bring your own model key and the add-on is free forever with unlimited calls, and the paid plans exist for people who would rather not manage a key at all.

SheetAI Pros & Cons
✓ Pros
- •The free tier is not a trial. Bring your own OpenAI, Claude, Gemini or Grok key and the add-on itself costs $0 forever, with unlimited =SHEETAI calls and unlimited formula generation — you pay only your model provider. Almost nothing in this category gives away the whole product and charges for convenience instead
- •Because the free path is BYOK, your marginal cost is the provider's rate card rather than a per-seat subscription. For a spreadsheet that runs a few hundred classification calls a month, that is cents, not $12
- •It lives inside Google Sheets as functions rather than as a side panel you paste into and out of. =SHEETAI in a cell means fill-down, ranges and recalculation all behave the way the rest of the sheet does, which is the entire reason to want this instead of a chat window on a second monitor
- •Multi-provider by design on every paid tier, not just the free one — OpenAI, Claude, Gemini and Grok are all selectable, so a model deprecation or a price change at one provider is a dropdown change rather than a migration
- •Replicate is wired in for bulk image, video and music generation straight from rows, which turns a sheet of prompts into a batch media job without any glue code. That is an unusual capability for a spreadsheet add-on and the clearest reason to pay for Pro
- •Result caching is explicit: the vendor states that repeating the same query pulls from its database rather than re-billing the provider. On a sheet you recalculate all day, that is a real and non-obvious saving
- •One-time credit packs exist alongside subscriptions ($29 / $79 / $139 / $299, up to 97M / 260M / 460M / 1B tokens), so a single bulk job does not force you into a monthly plan you then forget to cancel
- •Billing runs through Stripe's own customer portal and the vendor links it directly on the pricing page, which means cancelling is self-serve rather than an email to support
✗ Cons
- •The hosted Starter plan's ceiling is stated as roughly 500 AI runs a month. On a spreadsheet — the tool whose defining gesture is dragging a formula down 2,000 rows — 500 runs is one afternoon, and you will meet that wall faster than the price suggests
- •"Higher AI usage (soft unlimited)" on Pro is not a number. Soft-unlimited means a threshold exists that the vendor has chosen not to publish, so the $29 plan cannot be budgeted against a workload the way the BYOK path can
- •The credit packs are priced in tokens, not runs, and tokens are the unit you understand least when you are writing formulas rather than API calls. Converting "460M tokens" into "how many product descriptions" is work the buyer has to do unaided
- •BYOK being free is great for you and structurally awkward for the product: the cheapest path is also the most capable one, so the paid tiers are selling key management and hosting rather than capability. If you are comfortable pasting an API key, the case for $12/mo is thin
- •Google Workspace add-ons inherit Google's execution limits — script runtime, per-call timeouts, quota on the container — so very large batch fills can fail in ways that are the platform's fault but land on your screen as SheetAI errors
- •The testimonials carried on the pricing page are dated December 2022 and January 2022. Social proof four years stale on a live 2026 pricing page is a small thing, but it is the kind of small thing that reads as a product coasting
- •Sending spreadsheet contents to a hosted AI endpoint is a data-governance decision, and on the hosted tiers the vendor is in the path. For regulated or customer-identifying data, the BYOK route with your own provider agreement is the only version of this that survives a review
- •Team and domain licensing is not self-serve — the pricing page routes you to email support. Fine for a solo operator, friction for anyone rolling this out to a department
SheetAI Pricing 2026
Read off sheetai.app/pricing in September 2026. The vendor's own framing is “free with your own API key — or hosted plans”, with one-time credit packs for people who only need bulk runs. Pro is also sold annually at $290/year, which the vendor describes as saving about two months.

Marketers running bulk media and bulk fills
One-Time Credit Packs
Sold separately from the subscriptions, for bulk jobs that do not justify a monthly plan. Note that they are rated in tokens, not runs — roughly 1,000 tokens is 750 words of combined prompt and output, so the conversion into “how many product descriptions” is yours to do.
| Pack | Rated capacity | Note |
|---|---|---|
| $29 | Up to 97M tokens | Entry bulk job |
| $79 | Up to 260M tokens | ~2.7× the tokens for 2.7× the price — flat rate |
| $139 | Up to 460M tokens | Slightly better per-token than the $79 pack |
| $299 | Up to 1B tokens | Best per-token rate of the four |

The Only Decision That Matters: BYOK Or Hosted
Every other question about SheetAI is downstream of this one. The free tier is not a reduced version of the paid product — it is the same functions, the same unlimited calls, the same Replicate media models. The difference is who holds the API key and who gets billed for the tokens.
Run the numbers before you subscribe. Starter is $12 a month for about 500 AI runs, which is roughly 2.4 cents per run. Short classification or extraction calls on a cheap model through your own provider key will typically cost a fraction of a cent each. On volume, BYOK wins by an order of magnitude, and it keeps winning as you scale — while Starter's 500-run ceiling arrives after one long fill-down.
Hosted is the right call in a narrower set of cases, and they are all organisational rather than technical: a shared sheet where you cannot distribute a personal key, a client's Workspace you do not control, a finance policy that wants one predictable line item instead of a variable provider bill, or simply not wanting to think about key rotation. Those are legitimate reasons to pay $12 or $29. “It does more” is not one, because it does not.
Frequently Asked Questions
Is SheetAI free?
Yes, genuinely — and this is the most important fact about it. The BYOK (bring your own key) tier is $0 forever: you paste in an OpenAI, Claude, Gemini or Grok API key and get unlimited =SHEETAI calls and unlimited formula generation, paying only your own provider bill. It is not a 14-day trial and it is not feature-crippled; Replicate bulk image, video and music generation is included on it too. The paid plans exist to remove key management, not to unlock capability.
How much does SheetAI cost in 2026?
Read off sheetai.app/pricing in September 2026: BYOK is $0 forever. Starter is $12/month for hosted AI with roughly 500 AI runs a month. Pro is $29/month for hosted AI with 'higher usage (soft unlimited)' plus bulk media workflows, or $290/year — the vendor frames the annual price as saving about two months. Separately there are one-time credit packs at $29, $79, $139 and $299, rated up to 97M, 260M, 460M and 1B tokens respectively, with no subscription attached. Team and domain licences are quoted by email.
Should I use the hosted plan or bring my own API key?
Do the arithmetic on your actual volume. Starter's ~500 runs a month for $12 works out to roughly 2.4 cents a run; on a cheap model through your own key, a few hundred short classification calls will cost well under a dollar. The hosted plans are worth it if you cannot or will not hold an API key — a shared team sheet, a client's Workspace, a finance rule against personal provider accounts — or if you want a single predictable line item. If you are one person with a credit card and a spreadsheet, BYOK is the better deal and it is the same product.
What does SheetAI actually do inside Google Sheets?
It installs as a Google Workspace add-on and exposes AI as spreadsheet functions — the =SHEETAI family — so a cell can generate text, summarise, classify, extract or categorise using the contents of other cells as inputs. Because they are functions rather than a chat panel, they fill down, take ranges and recalculate like any other formula, which is the whole point. There is also a sidebar formula generator for describing a formula in plain English, and a Replicate integration for generating images, video and music in bulk from a column of prompts.
Does SheetAI re-bill me for the same query twice?
The vendor says no: repeated identical queries are served from its database rather than sent to the provider again. That matters more here than in most tools, because spreadsheets recalculate constantly and a naive implementation would bill every recalculation. Treat it as a meaningful cost control on BYOK, but not as a spend cap — if you are running large fills on your own key, watch your provider's usage dashboard for the first few days rather than trusting any caching claim in the abstract.
What are the limits I should worry about?
Two, and neither is in the headline price. First, Starter's ~500 runs a month is small for spreadsheet work — one long fill-down can consume it. Second, Pro's 'soft unlimited' is an unpublished threshold, so it cannot be planned against; if your workload is large and steady, BYOK gives you a number you control. Beyond SheetAI's own limits, Google Workspace add-ons run inside Google's script runtime and quotas, so very large batch operations can time out for reasons that belong to the platform rather than the add-on.
Who should not use SheetAI?
Anyone putting regulated, customer-identifying or contractually restricted data through it on the hosted tiers, because that routes your cells through a third party in addition to the model provider — use BYOK under your own provider agreement, or don't. Anyone who needs a hard, contractual usage ceiling, since the paid tier's limit is deliberately unpublished. And anyone rolling it out across a department, where the lack of self-serve team licensing means a support email stands between you and a deployment.
