Multi Calendar 2

Multi Calendar 2

By Lumman

Connect personal Outlook.com and Hotmail calendars to Claude alongside work Microsoft 365 and several Google accounts, each signed in with its own provider - one connector, one search for free time across all of them. Ask in plain words: what's on this week across all my calendars, find an hour free everywhere on Thursday, move my 3pm to Friday, accept Anna's invitation. Claude reads events, finds free time, creates, moves and cancels events and answers invitations. Invitations go out from your own address, through Microsoft or Google. A booking link offers one guest the times Claude picked. A booking page at lumman.co/book/your-name lets anyone book a time that is free within your working hours. A group poll lets several people tick the times that suit, then Claude books one. Guests need no account and see each time in their own zone beside yours. A circle finds time with colleagues or family who also use Multi Calendar - each member shares only when they are busy, never what an event says. Busy everywhere shows busy time from one account as private blocks in another, so a work calendar knows when your personal one is taken. Seeing events, changing events, and inviting and replying are switched on separately for every calendar account. Lumman keeps no copy of your calendars. Events are read from Microsoft or Google when Claude asks, and the words of every event - an invitation from a stranger included - are screened for prompt attacks by Google Cloud's Model Armor before they reach Claude. Microsoft lists Lumman Ltd, London, as a verified publisher. Free for every calendar, with one booking page and one circle; a plan adds more of both.

LYRC

LYRC

By LYRC

LYRC makes lyric videos for independent musicians. Ask ChatGPT to make a lyric video for your song, make a music video for a new single, or make Instagram Reels for a release, and LYRC builds them from your songs. You set up a song once at lyrc.studio. LYRC transcribes and times the lyrics and puts cut markers on the beat. After that, ChatGPT can: - make a new video for that song and fill every cut with stock footage (30 moods, from club nights to nature) or your own clips - show you the storyboard right in the chat - switch between lyric animation styles, or turn them off and set the font, colors and outline yourself - fix a misheard word or retime a line - add color grades and transitions that land on the beat - swap, zoom or lock individual clips - pull clips out of a video link - make up to 30 videos at once for a release, then keep or ditch each one - export a finished MP4 and post it to Instagram now or schedule it Exports and Instagram posts only go through after you confirm them in the chat. Finished videos play in the chat with a download link that doesn't expire. Limits: you need a LYRC account with at least one song set up at lyrc.studio. Songs are uploaded in the LYRC app, not in ChatGPT. Instagram posting needs an Instagram professional account connected in LYRC.

Mütalaa: Hukuk, Vergi, İçtihat

Mütalaa: Hukuk, Vergi, İçtihat

By Hasan Burak Taşyürek

Mütalaa supports Turkish legal research across public and private law through legislation, legislative rationales, public court decisions and Turkish Revenue Administration (GİB) private tax rulings. Find and read primary sources, examine legal concepts and institutions, and compare provisions, judicial reasoning and administrative interpretations with source links and citations. Use it to study a legal subject, map the rules governing an activity or relationship, examine how a provision is interpreted and applied, or investigate a specific document. It supports professional and academic research, legal education, and source research for legal opinions, pleadings, contracts, regulatory compliance assessments and organizational decisions. Research can address substantive and procedural rules, requirements and exceptions, powers and jurisdiction, rights and obligations, liability, sanctions and remedies. Research spans civil and commercial law, companies, enforcement and insolvency, employment and social security, consumer protection, property, family and inheritance, criminal law, public administration, taxation, constitutional law and other Turkish legal subjects represented in the available sources. Search legislation by topic, title, number or Official Gazette details. Sources include laws, decree-laws, presidential decrees, regulations, communiqués and available repealed instruments. Read full texts or specific articles, inspect chapter and article structures, search within legislation, and retrieve general or article-level legislative rationales where available. Distinguish legislative rationales from enacted provisions. Find public court decisions by legal issue and, where supported, court or chamber, date, and case or decision number. Sources include Yargıtay civil and criminal chambers, Danıştay, regional appellate civil courts, first-instance civil courts, the kanun yararına bozma collection and Constitutional Court (AYM) constitutional review and individual applications. Read and compare the facts, reasoning and outcomes of decisions alongside the relevant legislation. Research GİB private rulings as administrative tax interpretations tied to their facts and period. Connect a Mütalaa account and keep research inputs anonymous. Mütalaa provides legal information and source research; legal representation, submitting applications and access to private UYAP files are outside its scope. Foreign-law-only research and searches of regional criminal appellate or regional administrative courts are outside this release. Coverage depends on the available sources; exhaustive coverage, historical versions and instant updates are not guaranteed.

Magic

By Magic

Magic connects ChatGPT to your Magic account, so you can hand off real tasks to Magic's 24/7 human assistants without leaving the chat. Describe what you need, such as research, scheduling, or a booking. Magic creates the task on your account and routes it to an assistant. You can also see your recent tasks and check their status. Magic is for people who already have a Magic account. You sign in with your Magic Workspace login. Magic only reads and creates tasks in teams you belong to. New tasks go to your main Magic team unless you choose another team that you own. Before Magic starts a task, ChatGPT confirms the details with you, because assistants begin work right away. You can't cancel tasks, message assistants, or change your plan from ChatGPT yet. Use Magic Workspace for those.

Mailora

Mailora

By ArquiTech

Mailora is a privacy-focused European webmail hosted in France. This connector lets your assistant work with your Mailora mailboxes, contacts and calendars: search and read emails and full conversations, organize messages (mark, archive, move, tag), prepare drafts, reply and send with your confirmation, manage contacts, and plan meetings by finding free slots and creating events. You stay in control: on the Mailora consent screen you choose exactly which permissions to grant (read, organize, send, contacts, calendar) and which mailboxes the assistant may access. "Draft-first" mode is on by default, so emails written by the assistant are saved as drafts for you to review and send from Mailora. You can disconnect the assistant at any time in Settings → Developers.

MailVakt

MailVakt

By MailVakt

MailVakt helps you troubleshoot email deliverability and authentication directly from Claude. Investigate why emails may land in spam, check your domain’s DNS configuration, and get actionable recommendations for improving email security. Use MailVakt to: - Audit email authentication: Check SPF, DKIM, DMARC, MX records and domain alignment, plus BIMI, MTA-STS and TLS-RPT configuration. - Check blocklists: Look for domain and sending-IP listings on supported free public blocklists. - Analyze email headers: Inspect reported authentication results, sending IPs and alignment to identify potential delivery problems. - Generate DNS recommendations: Get proposed email authentication records and provider-specific setup guidance for monitoring or enforcement. - Test email receipt: Create a test address, send it an email, and inspect authentication, unsubscribe, content and deliverability findings. - Monitor DMARC reports: Add domains to your MailVakt account and summarize collected aggregate reports, including message volumes, pass/fail counts, sending sources and receiver actions. Ask Claude: “Check my domain’s email authentication,” “Analyze these email headers,” or “Summarize my DMARC reports for the last 30 days.” Domain checks, header analysis, DNS recommendations and email-receipt tests work without signing in. Managing domains and viewing DMARC reports require a MailVakt account. Report collection starts after you publish the provided reporting address in DNS. MailVakt recommends DNS changes for you to review and publish. Email-receipt tests confirm receipt and inspect the message; they do not measure inbox-versus-spam placement at Gmail or Outlook.

mailX

mailX

By Mailwarm Inc.

Why are my emails going to spam? Ask Claude, and mailX checks your domain live and tells you exactly what to fix. One request runs a full deliverability audit of any domain: SPF, DKIM, DMARC, blacklists and MX, with a pass or fail for each check and the fixes in priority order. No account, no API key, no setup. Try asking: - "Our emails from acme.com keep going to spam. What's wrong?" - "Is DKIM set up correctly for acme.com? I don't know the selector." - "Generate the SPF and DMARC records for acme.com. We use Google Workspace." - "Is our domain on a blacklist?" - "What SMTP settings do I use for Microsoft 365?" What mailX checks: - SPF, DKIM, DMARC and BIMI, with the exact record found and how to fix it - Whether your domain has the SPF, DKIM and DMARC records Gmail, Yahoo and Outlook require from bulk senders - DKIM selector detection, so you don't need to know yours - Major blocklists such as Spamhaus, Barracuda and SpamCop - MX, TXT, CNAME, PTR and full DNS lookups - SPF and DMARC records ready to paste at your DNS provider, with guidance for Google Workspace, Microsoft 365, SendGrid, Mailgun, Amazon SES and more - SMTP and IMAP settings for common email providers Made for founders, marketers, sales teams sending cold email, and IT admins. Every tool is read-only: mailX reads public DNS, never changes your DNS, never sends email and never asks for passwords. Built by Mailwarm Inc. (YC S20), an email deliverability company.

Manulyx

Manulyx

By SCOPT Inc.

Manulyx is a writing platform for LaTeX manuscripts, from the first draft through submission, reviewers' comments and revision. This plugin lets ChatGPT work on your Manulyx projects directly. Ask ChatGPT to find a project, read and search its files, tighten an abstract, rewrite a section or fix a table, then compile the paper and fix any LaTeX errors it reports. It can also find a published paper at Crossref and add it to the document's references by DOI, in the style the document already uses. You can search across your projects and get each passage back with a link to the file in Manulyx. Changes are made as small, exact replacements. They appear live in the Manulyx editor for you and your co-authors, and are recorded as tracked changes labelled with your name and "(ChatGPT)", which you and your co-owners can accept or reject. A restore point is saved before ChatGPT's first change. ChatGPT acts as you, with your role on each project: where you are a viewer or commenter it can only read. Each project has its own ChatGPT switch in the editor (Integrations, ChatGPT) to turn access off, separately from any other assistant. ChatGPT cannot delete, share or submit a project, or change who has access; those stay in Manulyx. Requires a Manulyx account.

Manusights

Manusights

By Manusights

Check any citation, anytime: a reference list in your draft, sources an AI assistant suggested (including ChatGPT in this conversation), a literature review, or the references in a paper you are reviewing. And check your manuscript before the journal does. Check references: paste references or ask ChatGPT to check the ones in your file or earlier in the conversation. Each reference is looked up in Crossref, the DOI registry and Retraction Watch and comes back with its source and check time: resolves, registered outside Crossref, retracted, expression of concern, correction issued, journal flagged, points to a different record, not found, or could not be checked. Only the references are sent, never your manuscript. Journal AI policies: ask what a journal allows on AI authorship, disclosure statements, AI-generated images, and reviewers' or editors' use of AI. Answers come from Manusights' dated record of the official policy page, with that page linked; when a record is out of date or the page could not be fully read, it says so and links the page instead. Where Manusights has measured it, you also get the journal's typical time from submission to acceptance. Manuscript preview: attach a manuscript (PDF, Word, ODT, RTF, TXT, Markdown or LaTeX, up to 50 MB) for a readiness score, a verdict and the main risks a reviewer is likely to raise. You can also read reviews already on your Manusights account. For researchers, students and reviewers who cite papers. Reference checks and journal AI-policy lookups work without an account. Manuscript previews and your saved reviews need a Manusights account; you can sign in with Google, an emailed link or a password. Limitations: checks report what the sources hold. They cannot tell whether a reference supports a claim, and "could not be checked" (common for books, theses and conference papers without a DOI) is not a sign of a problem. "Not found" means the sources hold no record, which can also be a typo. Up to 100 references per check. Journal policies cover the journals in Manusights' records. Manusights does not write or rewrite manuscripts.

Marvyn

Marvyn

By Eleven Square Labs

Marvyn is a marketing analytics tool for businesses. It reads the marketing data you have connected to your Marvyn workspace and answers questions about it with numbers Marvyn has already calculated. What you can ask: how your marketing is doing overall; which ad campaigns and ads are working or wasting money (Meta, Google, LinkedIn, Snapchat and Reddit ads); where your website funnel loses people; whether your conversion tracking can be trusted; why a number changed; and what to fix first. Data sources: ad accounts, website analytics (GA4), Google Search Console, Facebook and Instagram, and Shopify. Reliability: every answer says how fresh the data is, which sources are missing, and which figures were withheld because there was not enough data behind them. Marvyn says "not enough data" rather than guessing. Without an account: check whether AI crawlers can read any website (robots.txt rules for AI crawlers, llms.txt, sitemap and home page). Who it is for: founders, marketers and agencies who use Marvyn (marvyn.io). Connecting uses your existing Marvyn account, and available features follow your Marvyn plan. Limitations: read-only. Marvyn cannot change, pause, publish or spend anything, and reads only the one Marvyn workspace you connect.
