HealthX (Longevity)
HealthX supplies a dashboard design brief, visual reference and logo. ChatGPT uses these materials with health summaries you authorize in ChatGPT Health, or data you provide in the conversation, to create an interactive dashboard for HRV (SDNN), sleep and resting heart rate. Switch 7/30-day views, inspect exact daily values and explore evidence-linked observations in chat. This MCP receives no health-data arguments and provides no health-data ingestion, storage, scoring, cardiovascular risk assessment, ECG interpretation, clinical decision support, diagnosis or treatment. Health data stays in ChatGPT. Availability of ChatGPT Health depends on the user account and region. Interface generation time and details vary by model.
Diamond Star Technologies, Inc.
Healthy Food Guide looks up packaged foods by UPC, name or description and returns published healthy food related scores like Longevity and Food Integrity. Users can find the healthiest foods by category or compare which foods are healthier. Results include scores, ingredients, nutrition information, things to watch out for, and links to more detailed nutrition information tied to specific user goals.
Heapso
Heapso is a planning tool for teachers, made in New Zealand. Connect it to bring your Heapso plans into ChatGPT.
Search your lessons, units, worksheets, slide decks and week planners; open one to summarise or adapt it; draft a new plan in Heapso's format and save it to your account once you've checked it; or update a plan after you've approved the change. Earlier versions are kept.
Planning for NCEA? Look up achievement and unit standards by subject, level (Level 1, 2 or 3) and internal or external assessment, with links to each standard on the NZQA website, then turn a standard into a unit, lesson or revision worksheet and save it to Heapso. You can also check the learning areas, strands and phases of Te Mātaiaho, the New Zealand Curriculum, with links to Tāhūrangi. Heapso isn't part of NZQA or the Ministry of Education.
Also reads the class timetable you've imported into Heapso, and gives dated guidance on which New Zealand qualification (NCEA, NZCE or NZACE) a senior cohort will sit.
You need a Heapso account. Plans saved from ChatGPT are private to you. Heapso can't delete, share or publish plans from ChatGPT, and can't see billing, school administration or student records. For teachers, not students.

Helical
Helical lets you run biological foundation models on your own single-cell data, from the chat you're already in.
Upload an .h5ad dataset into your private Helical project, pick a model — scGPT, Geneformer, TranscriptFormer, Cell2Sentence or Nicheformer — and compute embeddings on Helical's GPUs. Follow the run while it goes, read the error if it fails, and download the embeddings when it finishes.
Nothing starts on its own. A run is quoted and queued first, and only begins once you approve it in a second, separate step. Every tool works inside the one project your account owns.
Runs use the credits in your existing Helical account.

Simply type @hepsiemlak and describe what you’re looking for in your everyday language: a 2+1 rental apartment in Beşiktaş, a sea-view villa in Bodrum, or a workplace within a specific budget. The app presents listings that match your search criteria on an interactive map with pins, along with a list displaying key details such as price, square meters, number of rooms, floor level, and building age.

The videos are made on your computer, so Explainer Studio works in Codex and in local threads of the ChatGPT desktop app, not in ChatGPT on the web or on mobile. The first time, it asks before installing its tools (about 1.5 GB). It needs no Heptabase account.

Hermoso AI
Hermoso is an AI marketing agent and AI ad generator in ChatGPT, with every Hermoso feature in one app. Ask in plain words and it makes video ads, image ads and posts for your brand, posts and schedules them to your own social accounts, builds paid campaigns on your own ad accounts and tells you what is working. Use any part on its own or all of it together: marketing on autopilot.
Create: make AI video ads and image ads from your saved brand profile (products, logo, colours and voice), from presenter-led UGC-style ads to product videos, product shots and social post visuals in any size. Show cut-ins of your own app or page screens over a video, extend a clip by cutting to a new shot, remake a video or static ad you like for your brand from its link, and turn one ad into headline or hook variations for testing. Files land in your Hermoso Library and can be saved to a Google Drive folder.
Research: see the ads competitors are running right now in the Meta, Google and LinkedIn ad libraries, find a brand's competitors from its website, break down which hooks and themes their longest-running ads use, and mine ad angles from real customer language.
Publish: post or schedule to the accounts you connect, such as Instagram, Facebook, TikTok, YouTube, LinkedIn, X, Threads, Pinterest, Bluesky and Telegram, see what is queued and what already went out, edit or remove a published post, and answer comments, direct messages, WhatsApp and Intercom support conversations.
Paid ads: build and run campaigns on your own ad accounts on Meta (Facebook and Instagram), Google, TikTok, LinkedIn, Reddit, Snapchat and ChatGPT ads: campaigns, ad groups and ads from your own creative, audiences and targeting, reports, pausing, resuming and budgets. New campaigns are created paused, and nothing spends until you turn it on.
Measure: see which posts and hooks perform best on each channel, read channel analytics, website analytics from Google Analytics and Search Console, and campaign reports, and get a review of your paid campaigns with suggestions on what to scale, pause, fix or test next.
Who it is for: founders, marketers, creators and agencies who want their marketing handled from one conversation.
Limits: Hermoso needs a Hermoso account, and it only acts on the brands and accounts you connect to it. It never posts, and never turns on a campaign, without your instruction. Generating ads and ad research use credits from your Hermoso account. Ad libraries only show what the platforms make public, so some advertisers return few or no ads. Video ads usually take a few minutes to render.
