Its headline offering is an SEO Agent that crawls your site daily, scores 50+ technical and on-page checks by ranking impact, and returns a prioritized fix list with copy-paste solutions. Around that sits Brand Monitor, which scans ChatGPT, Gemini, Perplexity, Claude, and Grok to show whether your brand is being recommended and which competitors are cited instead. The platform also bundles a Reddit Agent that surfaces relevant threads before competitors do, plus competitor keyword and real-time rank tracking. Behind the agents are the original writing tools: an article generator, paraphraser, AI detector, plagiarism checker, and a humanizer designed to make AI text read naturally. A separate AI Image Generator and utilities such as schema markup and llms.txt generators round out the toolkit. AISEO prices by plan type rather than mixing everything into one tier: writing plans start around $24/month, AI Visibility plans around $49/month, and the SEO Agent is sold as its own add-on from roughly $49/month with a $1 trial. It is positioned as a cheaper alternative to tools like Surfer SEO and Writesonic, and additional websites can share one subscription and its credits. **Pricing & Plans:** Free trial for $1; writing plans from about $24/month, AI Visibility plans from about $49/month, and the SEO Agent as a separate add-on from about $49/month. - **SEO Agent:** Crawls your site daily, checks 50+ SEO signals, and ranks every issue by impact with copy-paste fixes. - **Brand Monitor:** Tracks where your brand appears in ChatGPT, Gemini, Perplexity, Claude, and Grok, and which competitors get cited instead. - **Reddit Agent:** Finds Reddit threads discussing your brand or competitors so you can join the conversation early. - **AI writing & humanizer tools:** Article generator, paraphraser, plagiarism checker, AI detector, and a humanizer for natural-sounding output. - **Competitor & rank tracking:** Monitors competitor keywords, content gaps, and backlink moves with same-day updates. **Strengths:** Combines SEO auditing, AI-visibility tracking, and writing tools in one subscription; Agent-style daily crawling with impact-ranked fixes rather than raw issue lists; Cheaper entry pricing than many competing SEO suites; Additional sites can share one plan and its credits **Limitations:** Feature set is broad, so plans are split and costs add up if you want everything; Some user reviews are mixed on value and support; Does not push changes to your site automatically — fixes are manual [Profile (Markdown)](https://openaitools.app/tool/aiseo.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/sider.md) ## Frequently Asked Questions ### How do AISEO and Sider compare in monthly traffic?
