SheetAI.app

What is SheetAI.app?

SheetAI.app is a Google Sheets add-on that puts AI models inside spreadsheet formulas, so you can generate, classify and summarise text across whole columns without leaving the sheet. Its main function, =SHEETAI, takes a plain-English prompt and a cell reference. Companion functions such as =SHEETAI_RANGE and =SHEETAI_IMAGE handle blocks of cells and image generation. The add-on connects to OpenAI, Claude, Gemini and Grok models, and it uses Replicate for bulk image, video and music jobs.

SheetAI is built by IndianAppGuy Tech Pvt Ltd, whose founder Sanskar Tiwari is known online as indianappguy. The Google Workspace Marketplace listing showed more than 200,000 installs and a last update in February 2026. The homepage claims 198k+ installations and names Google, HubSpot and Netflix among its users. You can run it free with your own API keys or pay for hosted AI that needs no key. The product was live and taking subscriptions in October 2026.

Key Features

• =SHEETAI formula: The =SHEETAI function sends a plain-English prompt and cell data to an AI model and writes the answer into the cell. You drag the formula down a column to process hundreds of rows, such as product descriptions or survey comments, in one pass.
• Range functions: =SHEETAI_RANGE reads a block of cells rather than a single value, which suits summaries and analysis across a table. The Marketplace listing gives examples such as sanitising data, summarising feedback and categorising responses.
• Image, video and music generation: SheetAI creates images with =SHEETAI_IMAGE and runs bulk video and music jobs through Replicate models. A marketer can list prompts in one column and produce matching creatives in the next, with media costs billed to the Replicate account.
• Multi-model support: SheetAI connects to OpenAI, Claude, Gemini and Grok models on every plan, including the free tier. You can switch providers to compare output quality or cost without changing how your sheet is laid out.
• Formula generator sidebar: The sidebar formula generator turns a written description into a working Google Sheets formula. Users who struggle with nested functions can describe the goal in plain English and paste the suggested formula into a cell.
• Bring Your Own Key mode: BYOK mode lets you plug in your own provider API keys and run unlimited SHEETAI calls for $0. SheetAI’s FAQ says the key is stored in your Google account through Apps Script PropertiesService, not on SheetAI servers.
• Hosted AI plans: Starter and Pro plans provide hosted AI, so you can use the formulas without opening any API account. Starter covers roughly 500 AI runs a month, while Pro offers what SheetAI calls soft unlimited usage.

Pros

• Free plan with full features: SheetAI’s BYOK plan costs nothing and includes unlimited formula calls through your own keys. You pay only the AI provider’s usage fees, which a 2026 review notes is usually cheaper than a hosted plan for steady use.
• AI where the data lives: SheetAI runs inside Google Sheets, so prompts, inputs and outputs stay in the same rows. You stop copying text between a chatbot and a spreadsheet, and fill-down and recalculation work like normal formulas.
• Choice of models: SheetAI supports OpenAI, Claude, Gemini and Grok across all tiers. Teams can pick the model that handles their task best, and the FAQ says the underlying models cover more than 90 languages.
• Bulk media from a sheet: SheetAI’s Replicate integration produces images, video and music in bulk from a list of prompts. Ecommerce and social teams can build a batch of creatives from one product sheet instead of juggling separate media tools.
• Flexible payment options: SheetAI sells one-time credit packs from $29 to $299 alongside its monthly plans. Occasional users can buy tokens for a single project rather than keeping a subscription running all year.
• Large install base: SheetAI’s Google Workspace Marketplace listing showed more than 200,000 installs in 2026. That level of adoption means the add-on has been tried on a wide range of real spreadsheets and use cases.

Cons

• Low Starter allowance: SheetAI’s Starter plan covers only about 500 AI runs a month. One formula dragged down a 1,000-row sheet would exceed that in a single job, so most hosted users will need Pro.
• Unclear Pro ceiling: SheetAI describes Pro usage as soft unlimited without publishing a hard limit. Heavy users cannot easily predict when throttling might start, which makes planning large monthly jobs harder.
• Google Sheets limits: SheetAI inherits the quotas and execution limits of Google Workspace. A 2026 review reports that large batch runs can fail partway, so big datasets may need splitting into smaller chunks.
• Mixed support reviews: SheetAI’s Marketplace reviews are mixed, with some users reporting bugs, payment problems and unresponsive support. The developer was answering negative reviews in late 2025, but you should test carefully before relying on it.
• Outdated help pages: SheetAI’s FAQ page still listed a 50-call free plan and an $8 Unlimited plan in October 2026. Those figures conflict with the current pricing page, which can confuse buyers comparing plans.
• Data handling questions: SheetAI’s hosted plans process your spreadsheet prompts through its own service, and one 2026 review flags data governance concerns. Teams handling personal or confidential rows should read the privacy policy or stick to BYOK.

Who is Using SheetAI.app?

• Marketers: Generating ad copy, images and short video creatives in bulk.
• Data analysts: Classifying, tagging and cleaning datasets without code.
• Sales teams: Drafting personalised follow-up emails from lead lists.
• Researchers: Summarising papers and pulling out key findings.

Pricing

SheetAI.app is freemium, with a free BYOK plan and hosted plans from $12 a month (official prices, October 2026).

SheetAI’s own FAQ page still quoted a free plan of 50 calls and an $8 Unlimited plan, and Toolworthy said prices were not clearly disclosed, so treat the official pricing page as the current source. AI add-on pricing changes often, so check the live plan details before committing a team budget.

What Makes SheetAI.app Unique?

Spreadsheet formulas are SheetAI’s whole interface, so AI output lands in cells that recalculate, fill down and feed other formulas like any native function. Few add-ons combine text models from four providers with Replicate image, video and music generation in the same sheet. The BYOK plan also makes the add-on usable at zero subscription cost, which suits occasional users and anyone already paying for API access.

Compatibilities and Integrations

• Platform: Google Sheets add-on installed from the Google Workspace Marketplace.
• AI providers: OpenAI, Claude, Gemini and Grok models through hosted access or your own keys.
• Media models: Replicate models for bulk image, video and music generation.
• Shared sheets: Editors of a shared spreadsheet can run the functions, billed to the owner’s key.

SheetAI.app Tutorials

Getting started takes a few minutes inside Google Sheets.

1. Install SheetAI from the Google Workspace Marketplace into your Google account.
2. Add an OpenAI, Claude, Gemini, Grok or Replicate key, or choose a hosted plan.
3. Type a formula such as =SHEETAI(“Summarise this review”, A2) in an empty cell.
4. Drag the formula down the column to fill every row.
5. Open the sidebar formula generator when you need a standard Sheets formula written for you.

How We Rated It

Summary

SheetAI.app suits marketers, analysts and researchers who already work in Google Sheets and want AI output across many rows at once. The free BYOK plan makes it cheap to try, and support for four model providers adds flexibility. Its main limitation is reliability on large batch jobs, which depends on Google’s quotas and has drawn mixed reviews. Start with a small test column on the free plan before you scale up to thousands of rows.
