## 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

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
