## AdKit

AdKit is built around the idea that media buying involves too much repetitive clicking. Instead of forcing marketers back into slow ad manager interfaces, it exposes the advertising workflow as tools an AI agent can call. Teams describe what they want in natural language, and the agent fetches competitor ad data, drafts creatives, preps campaign structures, or answers questions about which campaigns to kill or scale.

The research side centers on a library of over a million ads with filtering by vertical, plus automatic tracking of chosen competitors across Meta, Google, and LinkedIn. Users see which ads are long-running evergreens versus short tests that competitors have already retired, along with weekly digest emails and the ability to save competitive creatives into a swipe file.

The creation and publishing side covers AI ad generation from a brand kit, cloning and remixing competitor ads, resizing for different placements, and pushing drafts into ad accounts. Every agent action lands as a draft in the AdKit dashboard by default, so nothing goes live until a human approves it. The platform reports working with Claude, OpenClaw, ChatGPT, Perplexity, Claude Code, Codex, Cursor, Grok, Hermes, n8n, and Gemini CLI.

**Pricing & Plans:** AdKit offers a 7-day free trial with no card required to start. Paid subscription plans are listed on the site's pricing page; agencies and multi-account users should check current tiers directly for per-account limits.

- **Million-ad competitor library:** Browse over a million ads or track specific competitors, filtering by vertical and sorting by how long each creative has been running.
- **AI ad generation and cloning:** Generate static ads from a stored brand kit, or clone and remix a competitor's creative so you can iterate on proven concepts in two clicks.
- **Ads MCP server and CLI:** Connect your ad accounts to an AI agent with a single configuration line, then call dedicated MCP tools or CLI commands for Meta, Google, TikTok, Reddit, LinkedIn, X, and Microsoft Ads.
- **Draft-first change safety:** Agent-created campaigns, ad sets, and creatives stay as drafts in the dashboard until you approve them, so nothing mutates your live account unexpectedly.
- **Performance analysis and monitoring:** Ask an agent which campaigns to kill, scale, or test next, and receive weekly digests summarizing what your watched competitors launched.

**Strengths:** Exposes ad ops through MCP so existing AI agent workflows extend naturally to advertising; Large searchable ad library plus automatic competitor tracking covers research and monitoring in one tool; Draft-first approval model reduces the risk of an autonomous agent altering live campaigns; Works across seven major ad platforms including Meta, Google, TikTok, and LinkedIn

**Limitations:** Advanced setup and best results depend on comfort with MCP servers and AI agent configuration; Value is heavily tied to the AI agent you use, so non-agent users get a smaller benefit; Pricing tiers for agencies managing many accounts are not fully transparent without checking the pricing page

## 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
