Kids Book Maker

Kids Book Maker

By Scrimba AS

Create something special for story time with your child. Kids Book Maker helps parents and other adults turn their ideas into narrated picture books for their children. Make a bedtime story, invent an adventure around your child’s favorite animal, or turn one of their drawings into the star of a book. Tell the app what your child enjoys and how old they are. Choose a language and illustration style, or let the app choose the details. Each book includes an illustrated cover, a picture on every page, spoken narration, and captions you can read together. Ideas for your next story: - A gentle bedtime adventure about friendship or sharing - A story starring a character from your child’s drawing - A reassuring tale about starting kindergarten or trying something new - A picture book in your family’s language - A playful adventure featuring pictures you provide This app is for adults creating entertainment for their children. You create and review the book, then choose how to share it with your child. Books normally have 8 to 12 pages, including the cover, and use a wide landscape format. Illustrations use the cover as a reference to help keep characters consistent, though generated pictures can vary between pages. Books are created as unlisted, with a claim link. They are not publicly listed, but anyone with the link can watch and claim an unclaimed book to their Scrimba profile. To make a book private, sign in, claim it, and change its privacy setting to Private. Powered by Scrimba.

Kilotest

Kilotest

By Jonathan Robert Pool

Kilotest integrates an ensemble of twelve independent rule engines to test a web page and stores the results as a structured report. The rule engines are: - Accessibility Checker (IBM) - Alfa (Siteimprove) - ASLint (eSSENTIAL Accessibility) - Axe (Deque) - Editoria11y (Princeton University) - HTML CodeSniffer (Squiz Labs) - Nu Html Checker (World Wide Web Consortium) - Pour Engine (David Yarham and Geoffrey Crofte) - QualWeb (University of Lisbon) - SureA11y (Jorge Rumoroso) - Testaro (CVS Health) - WAVE (WebAIM) Results are organized as a hierarchy. A report contains issues. An issue has violators: elements of the tested page reported as exhibiting the issue. A violator has diagnoses: explanations from rule engines of how the element exhibited the issue.

Kineticist

Kineticist

By Kineticist

Kineticist is a pinball publication and database. Connect it and ChatGPT can answer pinball questions from Kineticist instead of guessing: - This week's pinball news, new videos and podcasts from the creators Kineticist follows, and what's climbing the Hype Index of pinball themes. - Any pinball machine: editions (Pro, Premium, LE) with prices and production runs, whether it's still made, remakes and remasters, manuals and schematics. - Who designed a game: designers, artists, programmers and the rest of the team. - Where to play: venues near a postal code or city, or venues that have a particular machine. - Manufacturers, people, mods and anything else on kineticist.com, with links back to the pages. Answers link to kineticist.com so you can read more. It reads public Kineticist data only and needs no account. Limits: machine lists at venues come from Pinball Map and can lag; a game announced in the last few days may not have its editions in the database yet.

Klar

By Klar

Klar connects your ecommerce store, marketing channels and costs in one place. This plugin lets you ask questions about that data in plain language and get answers from your own Klar reports.

KleanApp

KleanApp

By TOBIAS SCHITTKOWSKI

KleanApp connects ChatGPT to your existing KleanApp account for commercial cleaning and facility operations. Ask who is scheduled at each site, where shifts have uncovered gaps, which absences are pending, how planned and actual hours compare, and which time-tracking findings need attention. You can also query tickets, invoices, orders and quotes. Sign in through OAuth. Access is limited to your tenant and the permissions of the signed-in user. An existing KleanApp contract and account are required; this app does not offer self-registration. Tool descriptions and returned field names are currently in German. When enabled for your tenant and authorized through a read-write token, the app can add an action to an existing ticket, set or overwrite a custom field on its latest action, and send a user an email or push notification. Access can be restricted to read-only queries.

Kleene Ai

Kleene Ai

By Kleene Ai

Kleene.ai's MCP server turns Claude, or any MCP-compatible assistant, into your AI data partner. It connects directly to your Kleene.ai organisation, so you can explore, analyse and manage your entire data stack through plain-English conversation, from raw source data to finished insight. Unlike MCP servers that cover a single layer of the stack, Kleene.ai brings ingestion, transformation, the warehouse and reporting together in one connection. Key features: - Warehouse discovery: search tables, read schemas, preview sample rows and automatically use the right SQL dialect for your warehouse. - Analysis and charting: turn business questions into SQL and get chart-ready results instantly. - Pipeline monitoring: spot failed extracts and transforms, read execution logs and get a plain-English explanation of what went wrong. - Transform discovery: search transforms by name or by the SQL they contain, ideal for impact analysis before schema changes. - Sandbox building: create and edit transforms safely in your Pipeline Editor Sandbox, with nothing reaching production until a person reviews it. - Built-in help: answers questions about Kleene.ai using the official product documentation. Built for everyone who works with data. Business users get answers without filing a ticket. Analysts skip the hunt for the right table. Engineers triage failures and draft fixes in minutes. Data leaders get a team that scales. Safe by design: read-first tools, sandbox-only changes, organisation-scoped access and visible, verifiable steps. Your data already tells a story. Kleene.ai gives you a partner to read it, explain it and help you act on it.

Klisten TokenIsolate

Klisten TokenIsolate

By Klisten Inc

Register a supplied target rule with allowed or denied sensitive-data categories and redaction preferences. Returns the validated local routing rule; it does not configure a network proxy or enforce controls in another system. List this organization's registered sensitive-data route rules and their targets, categories and enabled states. Returns local policy definitions; it does not discover or audit external network policies. Scan supplied text for supported sensitive-data categories with optional category and confidence filters. Returns matched spans, categories and confidence estimates; pattern detection is local and does not guarantee exhaustive privacy protection. Detect supported sensitive-data spans in supplied text and replace them with token placeholders while storing originals in this organization's recovery vault. Returns redacted text and tokens; redaction is reversible and is not irreversible anonymization. Evaluate a supplied target and text against local sensitive-data route rules. Returns ALLOW or DENY with matched categories and redaction preference; it does not block network traffic or forward the text to another system. Scan supplied flow-stage payloads and record local audit events with exposure categories and text hashes. Returns exposed stages, finding counts and CLEAN or EXPOSED status; it does not observe a live pipeline or intercept traffic. Look up a supplied recovery token in this organization's sensitive-data vault. Returns the original value and category if found, or an unsuccessful lookup; this reveals previously stored sensitive content and does not query an external vault. Compare a supplied candidate value with the hash stored for a local recovery token. Returns whether it matches, its category and the original only on a successful match; it does not validate an external identity or authentication credential. Pass supplied text and local pattern findings to the configured local classi

Klisten ToolGuard

Klisten ToolGuard

By Klisten Inc

Klisten ToolGuard connects Claude to your Klisten account through OAuth or a dedicated API key. Request policy gate decisions for configured MCP tools and retrieve existing attestations. Available tools: - toolguard_gate_check_paid requests a decision and may debit prepaid service credits. Requires gate:check. Reuse the same idempotency key after an uncertain request. - toolguard_attestation_get retrieves an organization-visible signed envelope and revocation status. Requires attestations:read. Grant only needed permissions and set account/key spending limits. Gate checks require sufficient balance and service/policy configuration. Missing or stale scan evidence can produce a charged unknown decision. Server pricing is authoritative. This connector does not create scans, execute target tools, process payments or payouts, or cryptographically verify receipt signatures. A gate decision is not a security guarantee or permission to execute an action.

Knyte

Knyte

By Knyte

Knyte is a shared workspace for thesis and project groups. A group keeps its project in a knyte: the purpose and current focus, the sources (uploaded PDFs, linked Google Docs and Word documents, links and pasted text), marked passages, notes, tasks, milestones and the decisions it has made. With this connector, every member's Claude works from the same material. What Claude can do: - Get a briefing on a knyte: what the group has confirmed, what assistants have contributed, findings no one has confirmed yet, and what members have asked of you. - Read the group's sources page by page, and search them for a phrase, with the page or paragraph to cite. - Format the group's reference list in the style it chose (APA 7, Harvard, Oxford, IEEE, Vancouver or Chicago), with in-text citations. - Read decisions with their reasoning, tasks, milestones, notes and recent activity. - Add notes, tasks, proposed findings and proposed reference details, start a new knyte, and draft a request to another member. Everything Claude adds is marked as an assistant's contribution and attributed to the person who connected it. Findings stay proposals until a person confirms them, and a drafted request reaches no one until the person sends it in Knyte. Claude cannot change the project's purpose, decisions, milestones or anything people wrote, and cannot delete anything. Claude sees only the knyten the signed-in person is a member of. Knyte receives tool calls and their arguments, never the conversation, and does not use content to train AI models. A free Knyte account includes one knyte of your own and two that others started.

Kryptos

By Kryptos

Kryptos brings your crypto portfolio, transaction history, tax figures and accounting ledger into ChatGPT, across 5,000+ exchanges, wallets and blockchains. Ask what you hold and what it is worth, search your transaction history by asset, wallet, label or date, review DeFi positions and NFT collections, and look at the ledger detail behind any trade. Kryptos also finds the data problems that make crypto tax wrong — missing prices, missing cost basis, sells with no matching purchase, balances that disagree with the ledger, wallets you never connected — and lets you fix them in the same conversation: recategorise a transaction, correct a price, merge a transfer that detection missed, or add a trade that never made it into an export. Finance teams can map transactions to a chart of accounts, apply categorisation rules, generate double-entry journals and push them to Xero, QuickBooks or Softledger. You sign in to Kryptos with OAuth and grant access to one workspace. Kryptos never asks for exchange API keys or wallet private keys in the conversation. It reads and records only — no tool can send, swap, withdraw, deposit or trade any asset. Requires a Kryptos account.
