Nucleus

Nucleus

By Second Team

Stop re-explaining your business to AI every session. Nucleus gives Claude the facts about your business so its answers stop being generic. Add your website and documents. Nucleus turns them into one structured business context: identity, offer, pricing, ideal customer, positioning, brand voice, competitors, goals and the things you never want said. Where something is missing, it asks you targeted questions to fill the gap. Connect it to Claude and every chat starts from how your business actually works: • Get a one-call brief of who you are, what you sell and what never to say • Look up products, pricing, buyer personas and competitors by name • Search your curated sections and uploaded documents, with the source for every answer • Suggest updates when something changes. Every change is queued for your review, so nothing lands without your say-so Built for non-technical owner-operators. No technical setup: connect it, and your context stays maintained as the business changes. Nucleus is part of Second Team and is included in every Second Team plan. It is also available on its own.

Nudges

Nudges

By Sponja

Just tell ChatGPT what to remember and when. Nudges confirms the exact time, then emails you the moment it's due. No app to install, no phone number, no cap on how many you set, and no paywall. It understands the way you actually talk: "in 30 minutes," "tomorrow at 9," "every morning at 8," "every other Friday." Every reminder comes back with the exact local time and the inbox it's headed to, so you catch a mistake before it matters. Ask for your reminders any time, and cancel any one in a sentence. Nudges is free and unlimited, and it reaches you in the inbox you already check. Your email is verified the moment you connect, so there's nothing to set up. We deliver reminders to that address and count basic usage events to run the service. We never store what your reminders say.

Nuira

Nuira

By Nuira

Nuira connects to your Shopify store, Meta Ads, Google Ads and Klaviyo, and keeps a model of the business: what each order earned after product cost and ad spend, which channels pay for themselves, which products carry the margin and what runs out next. Connect Nuira to Claude and ask in plain language: how last week went after ad spend, where this month's margin is going, whether a channel is earning its keep against your target ROAS, which products are about to run out, and what Nuira recommends doing first. Every figure comes from your own connected data, with its period and currency, and says how much of revenue has a known product cost. Nuira is read-only. It recommends, and you act in your own tools: it never changes your campaigns, your store or your ad accounts. Requires a Nuira account with at least one store connected.

NumbersGame MCP

NumbersGame MCP

By Numbers Game B.V.

Numbers Game connects your QuickBooks Online and Xero books to Claude, so you can ask questions about a client's ledger and act on the answers in the same conversation. Pull the standard financials — P&L, balance sheet, cash flow, trial balance, general ledger, AR and AP aging, transaction lists — and drill from a total straight into the transactions behind it. Search invoices, bills, journal entries, purchases, deposits, customers, vendors, items, and accounts by any field the ledger will filter on. Then write back: create and update invoices, bills, payments, journal entries, credit memos, estimates, purchase orders, and sales receipts; apply credits, convert a purchase order to a bill, void or delete what shouldn't be there; email invoices, estimates, and purchase orders to the customer; and attach supporting documents to any record. Built for bookkeepers and accounting firms: connect several client companies under one login, invite your team with per-user access to only the companies they work on, and keep every tool call logged. Claude tells you plainly when a company's ledger or subscription tier can't answer a request, rather than guessing.

Nusii

Nusii

By Nusii Proposals

Nusii is proposal software for agencies, freelancers and service businesses. This connector lets Claude work in your Nusii account: report on your proposals, find them, and prepare new drafts from your own templates. What you can do: • Ask about your pipeline: how many proposals are pending, accepted or rejected in a period, and your conversion rate. • Find proposals by title, document number, client or status, and read the full document with its sections and pricing. • Draft a new proposal from one of your templates or from scratch, for an existing client or a new one. • Edit drafts: rewrite sections, add, change or remove line items, apply taxes, and adjust settings such as theme, expiry date and deposit. Claude only sees what your Nusii team role allows — sales members only see their own proposals. Claude never sends a proposal: drafts stay in Nusii for you to review and send, and accepted proposals stay locked. Requires a Nusii account. Connect with your Nusii login; account admins can revoke connections and switch access off per team member under Settings.

Nutrition

Nutrition

By Anton Kutishevskyi

Nutrition is a personal food diary you keep in conversation. Tell Claude what you ate, share a photo of your plate, or send a barcode, and it logs calories, protein, carbs, fat, fiber, sugar, added sugar and caffeine. Alcohol tracking is opt-in. Key features: • Log meals, water, body weight and body measurements (waist, hips, chest, arms and more, in cm or inches), and edit or delete any entry • Saved meals: keep a meal you eat often under a name, with its ingredients, and log it again later — scaled by servings, or with single ingredients changed or left out • Barcode lookup for packaged foods (Open Food Facts) • Trends by day, week or month, a smoothed weight trend, and a record of how your goals changed over time • Weight trends in kg or lb • Search past meals to relog something you've eaten before • Import history from MyFitnessPal, Cronometer, Lose It! or MacroFactor. The file is parsed in your browser, so the rows never pass through the model • Export everything as a ZIP of CSV files, and delete your account at any time • Uses your timezone; the in-chat charts are available in 9 languages Your data is private to your account. All nutrition figures are estimates, not medical or dietary advice.
