Ultiwrite

Ultiwrite

By Ultiwrite

Ultiwrite is an AI-powered commercial diligence platform built to investigate the evidence behind business decisions. Submit financial statements, merchant processing records, business documents, acquisition materials, and other commercial evidence. Ultiwrite automatically determines which investigative capabilities apply, analyzes the available information, and reconciles findings across documents and relevant external sources. Rather than simply summarizing uploaded files, Ultiwrite examines financial coherence, entity relationships, document integrity, commercial risk, and contradictions that may affect the underlying opportunity. The result is an evidence-backed assessment designed to help users understand what the documents establish, what conflicts, what remains unverified, and where further investigation may be warranted. Ultiwrite supports business acquisitions, merchant underwriting, portfolio evaluation, commercial real estate diligence, counterparty investigation, and other evidence-intensive commercial decisions. Capabilities depend on the submitted evidence and available sources. Ultiwrite distinguishes supported findings from uncertainty rather than presenting assumptions as established facts.

Ask what you ate this week, how your weight is trending, what workouts you logged, or for a full progress report — answers come straight from your UltraFit360 food diary, workout logs, body metrics, and AI coaching memory. With your confirmation, it can also log the meals you eat, adjust your daily calorie, macro, water and step targets, plan meals, swap exercises, and assign or build workout programs. Your identity comes solely from your authenticated session, so the app only ever accesses your own data.

Unabyss

Unabyss

By OneType P.S.A.

Unabyss is a user-owned context layer for AI tools. It connects to the sources where your context already lives — Gmail, Google Drive, Calendar, Notion, Slack, GitHub, LinkedIn, X, Obsidian — and extracts a structured vault covering who you are, what you're working on, and how you communicate. With the connector enabled, Claude can pull that context at the start of any conversation instead of you re-explaining your role, company, stack, and preferences every time. What you can do: - Look up specific facts about yourself, your company, or past decisions, and ask synthesis questions across your entire context - Save durable facts, decisions, and preferences back to your vault as they come up in conversation - Load skills — ready-made playbooks for recurring work like daily briefs, investor updates, pre-call research, and content drafting - Generate topic-scoped Markdown exports to reuse in tools that don't support MCP - Connect new sources directly from chat, without leaving the conversation Your context stays yours. Permissions are granular per tool and per layer (Identity / Profile / Mind), connected sources keep context self-updating, and access can be revoked at any time. Unabyss is MCP-native and cross-platform, so the same vault works in Claude, Claude Code, Cursor, and any other MCP client.

Unblocked

Unblocked

By Unblocked

Unblocked is the context layer for agentic software development. It reasons across your code, conversations, issues, docs, product, and production systems so agents can complete work correctly with less human intervention. Coding agents know the code. They do not know why it was written that way, which of two conflicting docs is current, what a ticket decided, or what production is doing right now. Unblocked gives them that organizational understanding by connecting the context scattered across your code, messaging platforms, issue trackers, documentation, and product and production data, reconciling conflicts between sources, and enforcing the permissions you already set in each tool. One MCP server replaces a dozen. Context is ranked, compressed, and assembled server-side before it reaches the agent, so the agent reasons over higher-quality input. The result: reliable code that reflects how your team actually builds software, generated with fewer tokens and less back-and-forth. Works with Claude Code, Cursor, Windsurf, GitHub Copilot, and Codex over MCP, or through the Unblocked CLI and API. Connects to GitHub, GitLab, Slack, Microsoft Teams, Jira, Linear, Confluence, Notion, Google Drive, Sentry, Datadog, and more.

Unclass MCP

Unclass MCP

By unclass

Unclass is the classroom for independent language tutors: live classrooms with a built-in video call, and lessons with self-marking exercises on one screen. This connector links your Unclass teacher account to Claude, so you can plan and build lessons in conversation and then review and teach them in Unclass. What you can do: - Browse your courses, lessons, pages, and sections. - Create draft lessons with text, teacher notes, word lists, YouTube videos, and self-marking exercises (fill in the gaps, multiple choice, matching). - Revise individual sections without touching the rest of the lesson. - Duplicate, reorder, move, archive, and delete lessons, pages, and sections. - Mark a lesson ready once you have reviewed it. How it works: New lessons start as drafts. Saved lessons come with links to the teacher preview and the lesson editor, so you can check the result before using it in class. Lessons can teach English, Spanish, French, German, Italian, Portuguese, or Russian. Access and privacy: You sign in with your Unclass account and approve read access; Claude asks you to approve authoring access the first time it changes content. Claude can reach only the courses in your own school. Students, messages, classroom links, and personal dictionaries are never shared. Lessons already taught in a classroom keep their saved copy and are never changed. You can disconnect at any time in Account settings, and connections expire after 30 days. Requirements: an Unclass teacher account. Images and audio are added in the Unclass lesson editor.

Underpriced AI

Underpriced AI

By Underpriced AI LLC

Ask Claude what something is worth and get the answer from real eBay sold listings, not a guess. Underpriced AI is built for thrift store, estate sale, garage sale and online resellers who want a number before they buy or list. Say what you have, as you would type it into eBay: brand, what it is, size or pattern, any marks. Or paste a public photo link. You get a calibrated estimate with a range, the recent sales behind it, three list prices (fast, market, patient) with the two week sell chance for each, and what you keep after eBay fees. Tell it what you would pay and you get a buy or pass verdict. Things people ask it: "What does a Pyrex Butterfly Gold mixing bowl sell for?" "Is this Coach bag worth $25 at the thrift store?" "Show me recent sold prices for a Leica M4 body." "I can get this KitchenAid mixer for $40. What would I clear on eBay?" "How much do vintage Levi's 501s go for?" Ask for the comps and you get the most recent sold listings with the count, median and quartiles, so you can see the spread, not just an average. Signed in to your Underpriced AI account, a photo price is a real scan saved to your history, priced in your own eBay marketplace and currency, and Claude can prepare an eBay listing draft from it that you review and publish yourself at underpricedai.com. Nothing is listed, bought or charged through the connector. Works without an account for a few questions a day. Prices are USD and reflect eBay US unless you are signed in. Cross list to Poshmark, Mercari, Facebook Marketplace and more from the app once you have the number.

Underwrite

Underwrite

By LUCE CONSULTING - FZCO

Underwrite answers questions about Dubai residential property with figures from official records: Dubai Land Department sales and Ejari rent contracts, with listing asking prices in aggregate. Ask about a budget, a building, an area, a rent, a yield, new supply or a developer: - "I have AED 1.5M. Where can I buy a ready 2-bedroom that rents well?" - "Is Peninsula Three in Business Bay fairly priced?" - "How have apartment prices moved in Jumeirah Village Circle?" What you get: - Buildings that fit a budget, with the typical price paid, the gross rental yield and how easily units sell. - A building's fair-value range per square foot, how far asking prices sit from it, its recent sales and its service charge. - An area's prices, sales volume, the delivery schedule of new projects, and off-plan against ready. - The dates the data runs to, and links to each building's or area's page on underwrite.ae. How it works: every figure comes from a query on Underwrite's published data, and each answer is checked against the query results before it is returned. Lists put buildings whose data checks are clean first, and name the ones whose checks raised points to review. What it does not do: forecast prices, give financial advice, recommend a purchase, or show individual listings. Yields are gross: a year's rent over the price, before service charges and vacancy.
