Sift

Sift

By Local Marketplace Technologies Inc.

Sift keeps the research behind a decision in one place. Ask to compare options, such as daycares, strollers or apartments, and save the result as a Sift space: a table of options against the factors that matter, with source links and supporting quotes for researched values. Open the space to sort, filter, see located options on a map, add your own notes and share it with the people deciding with you. You can also continue an existing space: find more options, fill gaps or add a factor. Start a new comparison without signing in, then claim the same space to your Sift account. Connect your account to continue your saved spaces. New spaces can be viewed by anyone with their link. ChatGPT performs the research; Sift checks submitted values and citations but does not independently verify that every quote appears on its source page. Some cells stay blank when a fact cannot be sourced.

SimplySIM eSIM Finder

SimplySIM eSIM Finder

By SimplySIM

SimplySIM eSIM Finder helps travellers choose a data-only eSIM for a trip. Ask about a country or region and it lists SimplySIM plans with data allowance, validity, price, networks and coverage, so you can compare single-country, regional (for example Europe) and global options side by side. It can also check whether a phone model supports eSIM, including any caveats such as region-specific models. Intended for travellers planning mobile data abroad. Each plan comes with a link to its page on simplysim.co.uk, where you can read the full details. Limitations: plans are data-only (no calls or SMS). The compatibility check uses SimplySIM's device list, so a phone that is not listed should be checked in the phone's own settings for an eSIM option. Prices are shown in GBP or EUR and can change; the plan page on simplysim.co.uk shows the current price.

Simulado ENEM

Simulado ENEM

By Marcus Lemes

Treine com questões reais do ENEM de 2020 a 2025 em Matemática e Ciências da Natureza, além de algumas questões de Linguagens e Ciências Humanas cujos textos estão em domínio público ou sob licença aberta. Questões que reproduzem obras de terceiros protegidas estão excluídas. Para cobrir mais habilidades, o simulado também traz questões geradas por inteligência artificial a partir de questões do ENEM, sempre rotuladas como geradas por IA. Escolha uma área, o ano e a quantidade de questões. Depois de responder, receba os acertos, o gabarito, as habilidades para revisar e uma estimativa de nota TRI com faixa de incerteza. Simulados curtos têm faixas mais amplas. A nota TRI só aparece quando todas as questões de uma área são do mesmo ano, porque cada prova tem a própria escala. Cole a sua redação do ENEM, ou envie uma foto dela, e receba uma correção nas cinco competências usadas pelo INEP: escrita formal, compreensão do tema, organização dos argumentos, coesão e proposta de intervenção. Cada competência recebe 0, 40, 80, 120, 160 ou 200 pontos, como na prova, com um comentário sobre o que justifica a nota e como melhorar. O boletim mostra o total de até 1.000 pontos. Antes da nota, o plugin confere a estrutura do texto: conta palavras e parágrafos, estima as linhas com uma hipótese ainda não calibrada e pede que você confira a folha original e aponta se faltam agente, ação, meio ou finalidade na proposta de intervenção. Também lista os temas de redação dos anos anteriores para você treinar. O que ele não faz: não escreve a redação por você e não dá a nota oficial. A correção é uma estimativa feita pela IA com os critérios públicos do INEP. Não pede nome, CPF ou outros dados pessoais e não guarda o texto. Só com a sua autorização guarda um registro anônimo das respostas do simulado, para calibrar a dificuldade das questões. Os critérios vêm da publicação oficial do INEP "A redação no Enem 2025: Cartilha do Participante". Plugin independente, sem vínculo com o INEP ou o MEC.

Site SEO & AI Crawler Audit

Site SEO & AI Crawler Audit

By Agent Tools

Site SEO and AI Crawler Audit checks public web pages and reports what they publish right now: SEO tags, redirects, AI crawler rules, AI citation signals, landing page conversion and, for a site you own, what leaks publicly. People also call it Site Check. The exposure check works only on a domain you prove you own: the first call gives a DNS TXT record or a file to publish, and the check runs once it is live. It never looks up a person, a user name or an email address. Page and crawler checks: which of 14 AI crawlers robots.txt allows on a page and the rule that decided it; the title, description, canonical, Open Graph and Twitter tags and which are missing; and the 301 redirect chain with status codes and headers. Store and AI checks: one product page's SEO and Product structured data (price, GTIN, availability); a domain's llms.txt, agents.md, UCP file, sitemap and AI crawler rules; five AI citation signals of one page, each with evidence and a fix; and a sample of up to 40 sitemap addresses for broken pages and redirects. Landing page check: twelve conversion items such as the h1, the call to action and whether its links work, form fields, trust signals, a price section, viewport and a contact path, each with evidence and a fix. It is a checklist, not a forecast. Exposure check: exposed or clean with the top 3 risks and fixes, from dangling subdomains, leaked files such as .env, admin paths and masked API keys in the page's scripts, plus six legal signals with official sources. No port scan, and not legal advice. What it does not do: no speed test, no rankings or traffic, no JavaScript, no sign-in, no page text returned, and no private, local or internal addresses. It does not request a page that robots.txt disallows for Agent Tools. robots.txt is a request, not access control, and a firewall can treat real crawlers differently. It stores nothing about you or the site. Answers are cached for five minutes, and the only lasting record is a daily count of calls per tool.

Sitewalk: SEO Audit & Crawler

Sitewalk: SEO Audit & Crawler

By Aditya Sharma

Sitewalk crawls a website and reports its technical SEO problems ranked by impact: missing or duplicate titles and descriptions, broken links and images, redirect chains, missing canonicals, noindex pages and slow responses. Each issue comes with the number of pages affected, example URLs and a suggested fix. Without signing in, or for a site you have not verified, it checks the single page you give it. Sign in with your Sitewalk account and verify a site you own to crawl the whole site. The crawler identifies itself as SitewalkBot, obeys robots.txt, and keeps a slow, polite pace. It does not render JavaScript, so pages that build their content in the browser may show fewer issues than a visitor would see. Powered by LibreCrawl.

SiteWarming

SiteWarming

By SiteWarming

SiteWarming turns parked domains into live, content-rich sites that build search trust over time. With this plugin, domain investors and portfolio owners can manage their SiteWarming portfolio in plain language from ChatGPT. Read: list and search your domains, open a full report on any domain (DNS and SSL health, content schedule, warming progress, valuation) and see a portfolio summary. Act: launch one domain or up to 20 at once through a guided setup, build a Domain Brief through a short interview, add tracked domains, update settings on live domains and connect DNS through supported registrar integrations. Safety and limits: actions that change live sites, DNS or your portfolio are marked as write actions, and ChatGPT may ask for your confirmation before running them. Removing a domain from SiteWarming never releases or transfers it at your registrar, and registrar transfers are not possible through this plugin. You sign in with your own SiteWarming account, and the plugin can only see and change what that account can. Requires a SiteWarming account.

SKU.io 3PL Quote Compare

SKU.io 3PL Quote Compare

By SKU.io

Upload the rate cards you got from the fulfillment warehouses you are considering (one row per fee, or one row per provider) and describe your order profile: orders a month, units per order, B2B orders, what you receive and store, returns and kitting. The 3PL Quote Compare prices every fee against that profile, applies each provider's monthly minimum, and shows monthly, annual and per-order cost per provider with a breakdown by fee category. Services a quote leaves out are listed as not quoted instead of silently counted as free. Providers are only the ones you enter; it never suggests or ranks 3PL companies, and shipping is left out unless you include it. Files are processed in memory for the one request and never stored. No account is needed.

SKU.io ABC Inventory Analysis

By SKU.io

Upload a sales or orders CSV, such as a Shopify orders export, and the ABC Inventory Analysis ranks every SKU by revenue share (A, B and C) and by how steady its weekly demand is (X, Y and Z). Each SKU gets a combined class such as AX or CZ and a rule-of-thumb stocking policy, so you can see which products drive the business and which are erratic tail items. Revenue comes from a price or line total column, an optional price list, or units if neither exists. Results appear as a sortable table. Files are processed in memory for the one request and never stored. No account is needed.
