Vertical
By Vertical
Stop pasting screenshots of your runs into ChatGPT. Vertical syncs directly with Garmin, COROS, Polar, Suunto, WHOOP, and Oura, so ChatGPT already knows your training load, thresholds, and recovery before you ask. Ground ChatGPT by giving it access to 500+ peer-reviewed sports-science papers and the same physiological models — critical-power zones, thresholds, fitness/fatigue tracking and more — coaches use. Build or adjust your training plan in chat, and sync the workouts straight to your watch.

Vertiso Memory
By Vertiso Corporation
Vertiso Memory is a portable, user-owned memory layer for AI agents. Connect it once, and your assistant can capture and recall durable facts, decisions, preferences, and project context across every tool you use, rather than starting from scratch in each new conversation. It exposes a small, composable toolset over MCP: remember to capture a durable fact, recall for hybrid search with synthesized answers, search for a ranked hybrid record lookup, and get_memory to inspect specific memories. Session tools like hello, handoff, and wrap-up let work continue cleanly across sessions and devices. Your data is yours. We do not train AI models on your content. Memories are sent to third-party LLM providers solely for retrieval and synthesis, under those providers' standard no-training API terms, and are deletable upon request. Works with any OAuth-capable MCP client. Connect by adding the server URL; client registration and sign-in happen in the browser, with no API key to paste. Available worldwide except where prohibited by applicable law or unsupported by our service providers.

Verus by Markst
By Markst Ltd
Verus prices private-credit loans deterministically: the same inputs always produce the same price. It is the valuation engine behind Markst Ltd, an independent private-credit valuation firm in London. What you can do from Claude - Price a deal: DCF value per 100 of outstanding, with a low / mid / high range and credit metrics. - Explain the mark: sensitivity ladders on spread, hazard rate, recovery and rates. - Stress a portfolio: apply predefined macro and sector scenarios and see the per-deal and NAV impact. - Cross-check pricing: comparable deals with implied spreads. - Review a fund: positions, NAV, weighted-average spread and concentrations. - Register a deal from a pasted term sheet or credit memo. - Score a deal on factors (direct lending, mezzanine, CRE, distressed) from the inputs you supply. How it works Pricing is a discounted cash-flow model with a hazard-rate credit adjustment and modelled recoveries. There is no machine-learning pricing and no randomness. Every write tool records a valuation run, so each number has an audit trail. No tool deletes or overwrites data. Limits Results depend on the deal terms and assumptions held in your Verus account. The multi-factor tool refuses when a required input is missing rather than assuming one. Deal creation from text uses an AI extractor that can search the web to fill gaps; turn web search off for private material. Access A Verus account is required (beta.markst.com). Sign-in uses OAuth: you choose read-only or read-and-write access, and your password never reaches Claude.

Very Simple Notes
By Portfoliobox Stockholm AB
Very Simple Notes is a clean notes app for you and your agent. Folders on the first page, notes in Markdown, a calm place to write, and nothing you do not need: no templates, no databases, no blocks. The apps run on iPhone, iPad and Mac. You and Claude share the same notes. Write a packing list on your iPhone in the morning, and ask Claude in the afternoon to add what you forgot. Ask Claude to turn a meeting into notes with decisions and action items, to save a recipe in Recipes, or to find what you wrote about the website plan; you read and edit the result on your iPhone, iPad or Mac. Nothing is copied between apps: it is one set of notes, in the folders you already see. Connected to Claude, your notes become something Claude can read and write. Claude can list your folders and notes, read a note in full, create a folder, create a note in the right folder, edit a note's title or body, star it, move it to another folder, archive it or bring it back, attach a file such as a photo, a receipt or a Markdown file, and read the files on a note, including looking at a photo. Notes are Markdown with headings, lists and checklists; the apps show them richly and never show the syntax. What Claude cannot do: remove a file from a note, or delete a folder. Deleting a note is possible but permanent, so the tool is marked destructive and Claude asks first; archiving is how a note leaves the list without being lost. A connection is a personal token for your own notes only. You can see and revoke it at any time in the app under Account.

Very Simple Projects
By Portfoliobox Stockholm AB
Very Simple Projects is personal project management for people who work with AI agents. Projects hold numbered tickets: a title, a Markdown body, a status, labels, a star, files and a comment thread. The apps run on iPhone, iPad and Mac. You and Claude work in the same tickets. You test and file what you find, with a screenshot, from your iPhone, iPad or Mac; Claude reads the ticket, fixes it and reports back in the thread. Or Claude files what it finds while it works, and you decide what happens next. Connected to Claude, a project becomes a place where both of you file and report. Claude can list and read tickets, file new ones, comment in the thread, set a status (new, in progress, blocked, done, deployed, or the project's own), assign existing labels, star a ticket, attach a screenshot or a log, and read the files a person attached. Blocked needs a note that asks the person something concrete; deployed is only for a change confirmed live. Every status change is written into the thread with its note, so the trail is complete. What Claude cannot do: delete a comment, remove a file, invent labels or statuses, or delete a project. A ticket may be deleted only when it should never have existed. At connect you pick one project, or all of them. A token can be revoked at any time in the project's settings, and the person sees in the app what was filed and by whom.

VesselTwin

Connect VesselTwin to ask ChatGPT about the boat records you already keep. New to VesselTwin? Visit vesseltwin.io to create a free account, then select Connect and sign in. Basic access shows approved boat, maintenance, equipment, and document metadata. Owner Pro customers can separately opt in to let ChatGPT read private records, including extracted document text, for boats they own. An optional second permission lets ChatGPT send proposed notes, checklists, maintenance entries, and measurements to the VesselTwin Inbox for owner review. Nothing becomes a saved record until the owner accepts it, and customers can turn either permission off at any time. Photo files and private records from collaborator-only boats are never included.

Vestd
By Vestd
The Vestd connector gives your AI direct access to your company's equity management data - shareholders, share classes, option grants (EMI, ESOP, CSOP, unapproved, growth shares), stock transfers, valuations, dividends, directors, and statutory filings (SH01s, confirmation statements, resolutions). Instead of navigating the Vestd platform, ask your AI to investigate an issuance, trace a grant's acceptance and signing status, check share authorisation headroom across companies, review governance settings, or summarise ownership structure and dilution - all grounded in your live Vestd data. Built for founders, finance teams, and company secretaries who manage equity on Vestd and want faster, conversational access to the records behind it.

VeteranHQ VA Benefits
By Silicon Vanguard LLC
VeteranHQ gives Claude reference and calculation tools for U.S. veterans working through VA disability compensation, plus read-only access to a veteran's own VeteranHQ records. The reference tools work with any VeteranHQ account. They combine ratings with the 38 CFR 4.25 Combined Ratings Table, including the 4.26 bilateral factor; look up monthly compensation from VA rate tables; estimate retroactive pay for a rating increase; show the rating criteria for a diagnostic code at every tier; compare a current rating with the tiers above it; total incapacitating episodes for diagnostic code 5243; list documented secondary conditions; check presumptive lists by exposure or service era; search 38 CFR, legal doctrine and Court of Appeals for Veterans Claims decisions; explain what a C&P exam covers; point to free accredited help and the Veterans Crisis Line; and search VeteranHQ's published guides. Veterans can also let Claude read their own profile, ratings, claims and evidence, VA.gov-synced claim status, and uploaded documents with their extracted text. Identifiers such as Social Security and VA file numbers are masked by default. Every tool is read-only, every personal read is logged, and access can be revoked at any time. VeteranHQ is an independent product of Silicon Vanguard LLC and is not affiliated with or endorsed by the U.S. Department of Veterans Affairs. It provides educational information, not legal or medical advice, and it does not prepare, file or submit claims. Only VA decides ratings, effective dates and payment amounts. Each result says whether it is an exact table lookup or an estimate.

Every tool is read-only and reaches only the clinics your Veterical login can access. Schedules and payments are shared as counts and totals: pets, owners, contact details, individual appointments, medical records and payment transactions are never returned to Claude.

Vezna
By Ninefold Ltd
Vezna is an AI-native accounting firm for Bulgarian companies. Its agents keep the books from your bank feeds and invoices, matching every payment to its document and asking when something is missing, and accountants review the work and file the returns. Connect Vezna to ChatGPT to work with your company's books in plain language: • Ask about cash across your accounts, monthly P&L, spending by category, revenue by client, and the estimated VAT position with its filing deadline. • Look into the general ledger: the trial balance, accrual P&L, who owes whom, the draft VAT return, and why each journal entry was proposed. • See what Vezna is still waiting on this month (payments without an invoice, invoices to issue, unexplained bank lines) and close the gaps: search the company mailbox for a missing invoice, submit it to Vezna, or answer Vezna's question about a payment. Figures come from Vezna's own calculations over your books. VAT figures are estimates and ledger figures are drafts until your accountant reviews them; your accountant files the returns. Vezna can't make payments, file returns, approve ledger entries, change settings or delete data. Personal identification numbers (ЕГН/ЛНЧ) and full card numbers are masked in every result, and every tool call is logged in Vezna, where you can revoke the connection at any time. Requires a Vezna account as an owner or team member of the company. Searching and filing from email also needs the company's Gmail mailbox to be connected to Vezna.
