## Numerous.ai

Numerous.ai targets a very practical gap: most teams work in spreadsheets, but most AI chat tools live in a separate browser tab. The add-on closes that gap by exposing AI as a spreadsheet function. You type a prompt in one cell, reference other cells in it, and drag the result down a column — the AI then returns a distinct answer for every row, whether that is a rewritten product description, a categorised support ticket or a normalised country name.

Because it is built for bulk use, the product emphasises cost control and reuse. Identical queries are cached rather than re-run, which keeps token consumption down across large sheets, and the pricing is expressed in characters of input and output per person rather than opaque credits. There is no need to hold your own API keys — the service manages provider access, and a single plan covers everyone on the team.

The typical audience is operations, marketing and research teams. Marketers generate ad copy variants, keyword lists and campaign structures at scale; researchers summarise, extract and classify survey or social responses; data teams clean and standardise messy inputs; product people prototype prompts and share results. Setup is a one-click add-on install for both Google Sheets and Excel, and support is handled by email from a US-based team.

**Pricing & Plans:** Paid subscription with a paid trial: 7-day trial for $1, then a per-person plan that includes 1,000,000 characters of ChatGPT input and output per person, usable in both Google Sheets and Excel. Annual billing saves around 57%. Cancel anytime and keep remaining tokens; custom plans available on request.

- **AI as a spreadsheet formula:** Use AI in any cell through a simple function — no API keys, no external chat window, no copy-paste between tabs.
- **Bulk processing with caching:** Drag a single prompt down a column to process thousands of rows, with identical queries cached so you are not charged twice for the same work.
- **Summarisation and classification:** Summarise, rewrite, extract and classify long bodies of text such as surveys, articles or social posts into clean structured columns.
- **Marketing content at scale:** Generate ad copy, keyword lists, SEO content and campaign structures directly from your sheet's own data.
- **Team-friendly plans and support:** One plan covers the whole team, results are shareable within the sheet, and priority email support is included.

**Strengths:** Works inside the tools teams already use, so no new workflow to learn; No API keys or provider accounts to set up; Query caching keeps bulk runs cost-efficient, especially across thousands of rows; One plan covers the whole team in both Google Sheets and Excel

**Limitations:** Requires a paid trial and subscription rather than a permanent free tier; Usage is capped by character allowance, which heavy bulk users can exhaust; It depends on third-party AI providers, so model behaviour and availability are outside your control

## Sheldon AI

Sheldon AI is positioned as a productivity-focused Chrome extension rather than a standalone chat app, so the assistant shows up exactly where you are already working. Instead of switching tabs to a separate chatbot, you describe the outcome you want — a polite follow-up email, a spreadsheet formula, a LinkedIn post — and Sheldon produces a ready-to-edit draft in under five seconds. The extension is guided by a keyboard shortcut and works across sites such as Gmail, Google Sheets, LinkedIn, and Quora.

The feature set revolves around a handful of high-frequency knowledge-work tasks. Email writing lets you specify tone and context to generate professional replies, while an Excel module turns a plain-language description of an operation into a working formula. A content-generation mode produces LinkedIn posts, Twitter threads, website copy, video scripts, and keyword suggestions for campaigns. There is also a coding helper that writes code snippets or offers hints and step-by-step guidance for development problems.

Sheldon is distributed as a free Chrome extension with no daily data limits, and the team throttles usage if it detects automation rather than human typing. An optional upgrade unlocks more capacity. The project is maintained by Mystic Labs, which says it keeps improving the extension as the generative AI space evolves and welcomes feature requests from users.

**Pricing & Plans:** Free to install and use in Chrome, with all features available and no daily data limits; usage may be throttled if automation is detected. An optional paid upgrade adds extra capacity.

- **In-context AI assistant:** Summon the assistant from any browser tab or supported site such as Gmail, Google Sheets, LinkedIn, or Quora.
- **Email reply drafting:** Describe the tone and context you want and Sheldon generates a polished professional email reply you can edit and send.
- **Excel formula generation:** Explain in plain language what a spreadsheet should calculate, and Sheldon returns a working Excel formula.
- **Marketing content creation:** Produces LinkedIn posts, Twitter threads, website copy, video scripts, and keyword suggestions for campaigns.
- **Coding help:** Analyzes your coding problem and returns code snippets, hints, or step-by-step guidance.

**Strengths:** Runs inside the browser, so there is no tab switching to a separate chatbot; Covers several everyday tasks: email, spreadsheets, marketing copy, and code; Free tier with no daily data limits advertised; Simple keyboard shortcut activation on supported sites

**Limitations:** Available only for Google Chrome at present; Advanced generations require a paid upgrade and free usage can be throttled; Quality still depends on how precisely you describe the task
