ContextDB
By SaaS Labs
ContextDB gives ChatGPT memory for one ContextDB project. Save facts a user states, recall them in later conversations, and check remembered details before a booking, refund, or account change. Each check returns act, ask, or abstain. Tentative details wait for the user's confirmation, and any memory can be deleted. Sign in with a ContextDB Cloud account and choose one project. ContextDB Cloud is in hosted alpha with no availability SLA.

Contexter
By Contexter
Contexter is a personal working environment that lives outside any single AI. Your Telegram messages and the results you produce with AI assistants become records in your own pool; you curate them into contexts and work with the same, always-current state from ChatGPT, Claude, Telegram or the web. With Contexter connected, ChatGPT can: - list your contexts and show what each one holds; - read a context's records and answer questions from them; - save a result of your work (a plan, a list, a summary) into a context — only when you explicitly ask; - tell you who will see a record before it lands in a shared context; - send a result into a Telegram group chat you take part in, or post an invitation link so the people there can join a shared context — both only when you ask for it. Contexter never saves anything silently: every write happens on your explicit request, deletions are reversible for 7 days, and shared contexts always show their audience. Nothing is collected from your conversation beyond what you ask to save.

Conveo
By Conveo
Conveo helps research, product and marketing teams understand their customers through interviews. Conveo's AI moderator interviews real participants over video, and this plugin connects ChatGPT to your Conveo workspace so you can plan studies and get answers from the interviews without leaving the conversation. What you can do: - Analyze interviews: ask what participants said about a topic and get an answer backed by cited quotes, tables and charts. - Find moments: search interview clips for what participants said about a keyword. - Design studies: create a new interview study with topic-guide sections and questions. Studies are created as drafts; nothing reaches participants until you launch it in Conveo. - Track fieldwork: see how many interviews are complete, in progress or screened out, and how your quotas are set up. - Reuse findings: browse the storylines and insights your team has already published. Requires a Conveo account. ChatGPT only sees the studies your account can already access, and Conveo never shares participants' contact details.

Conversion Tracking by PaidSync.ai
By PaidSync.ai
Conversion tracking checks and setup for your website, inside Claude. Review the tags, triggers and variables in your containers, see which version is live and which changes are still waiting to publish, and audit a container for tags without triggers, triggers no tag uses, paused tags, and a missing conversion linker or analytics configuration tag. Get the install snippet for a container. When you ask, it can also create workspaces, create and edit tags, triggers and variables, set up form submission tracking, analytics event tags and ad conversion tags, open a preview link, create a version and publish it. Publishing to your live site needs your explicit confirmation, and so does deleting a tag. PaidSync.ai reports on and manages accounts you own; it is not an ad network and serves no ads. Works with Google Tag Manager. PaidSync.ai is an independent product and is not made or endorsed by Google.

convert.express
By droozhok
Turn a recording into a transcript without leaving the chat. Give Claude a YouTube link, a direct link to a media file, or upload a file of up to 2 GB. Audio (MP3, WAV, M4A, FLAC and more) and video (MP4, MOV, MKV, WebM) both work. You get the transcript as plain text, SRT or VTT subtitles, or text with timestamps and speaker labels. You can also ask for an AI summary, a list of action items, or a translation into 103 languages. Subtitles keep their timecodes after translation. One ZIP holds every result, and a share link gives you a web page to send to others. Three transcription models are available: Microsoft MAI-Transcribe, OpenAI Whisper and Google Gemini. Most files finish in under a minute. Some use each day is free. After that, Claude shows a short preview and a payment link for you. Pricing is pay as you go: €0.02 per minute, €0.50 minimum, no subscription. Files and transcripts are deleted 24 hours after the last activity, or right away on request, and are never used to train AI models. No account or API key is needed to start.

Education
Corroborum
By Corroborum
Corroborum lets Claude search the scholarly literature directly. Ask a research question in plain language and Claude calls Corroborum to find real papers: each result is a live record from OpenAlex, the open catalogue of over 300 million scholarly works (220M+ research papers across every field), with its title, authors, year, venue, citation count, full abstract when one exists, DOI, and a link to a free full-text copy when one exists. Two tools: - search_papers: ranked search for one plain-language query, with optional filters (years, publication types, fields, open access, minimum citations, language, countries, excluding preprints or retracted papers) and paging. A DOI or OpenAlex id as the query puts that paper first. - expand_citations: follow the citation graph from a paper: its references, the works citing it, or related works. Every hit carries the paper's retraction status from OpenAlex at search time, so Claude can tell you before you rely on a paper that has been retracted. Results are data for Claude to read and cite; you open the DOI to check the source yourself. Useful for literature reviews, thesis and grant writing, checking the evidence behind a claim, clinical and policy questions, and any decision where you want the research behind it. Privacy: the text of your queries is not stored. To answer a search, the query is sent to OpenAlex and to Voyage AI (relevance ranking). Corroborum never sees your conversation, only the tool calls Claude makes. Plans: a free plan with 25 searches a month (no card needed); paid plans for heavier use at corroborum.com/pricing.

Cosmic Rebellion is a trading card game in ChatGPT. Pick a starter deck and play a full match against the built-in opponent. The table deals the cards, enforces the rules, and handles every click. Use it when you want to play. It does not create an account, play cards for you, or decide rules on its own. The table is the source of the rulings.

coSow
By coSow
coSow is the pre-sales workspace for ERP and data implementation partners. Connect it to Claude and work your deals in conversation: paste a discovery call transcript, email thread or notes, and coSow creates the deal, fills in the scoping questionnaire, and builds an hours estimate against your firm's own rate card and resource plan. Ask Claude what is still missing, fill the gaps, adjust hours or discounts, then generate a Statement of Work in your firm's template and get a download link for the SOW or the estimate workbook. Every action runs as you, in the workspace you choose when you sign in, with exactly the permissions your coSow role has. Read tools change nothing; write tools only change the deal you name. You can disconnect at any time from coSow Settings or from Claude. Requires a coSow account. Learn more at cosow.ai/connect.

Cranes
By Cranes
You are what you think. An understanding of how you think, brought into ChatGPT. Cranes keeps a working draft of how you think. It reads what you write, the conversations you bring in from ChatGPT or other AIs, and pages from Notion or your files, and drafts chapters about the judgment underneath: what you notice, what you care about, and what has changed your mind. Chapters point back to the entries they rest on, and Cranes revises them as you add more, correct them, or change your mind. Connect Cranes to ChatGPT to bring your thinking into your work: • For a decision, a piece of writing, or a plan, ChatGPT can ask Cranes for the parts of your thinking that bear on it, with where each part came from. For many requests, nothing applies and nothing comes back. • Type @cranes in a message to ask ChatGPT to use Cranes. • When you share your own thinking, ChatGPT can offer to save it to Cranes, and nothing is saved unless you say yes. You can also ask it to save an idea, a correction, or a change of mind any time. When you connect, you choose what ChatGPT can use: your own thinking, your team's, and any groups you're in. Your own thinking is only for you; a team's thinking and a group's are kept separately, and an answer meant for others doesn't draw on your own. Each call sends your current message and, when useful, one sentence on what you want; earlier messages aren't sent. Bringing in your chat history is a separate step, and happens only when you ask.

create-ebook
By LMT Digital Creations
Turn an idea into a finished book. Tell ChatGPT what you want to write (a how-to guide, a workbook, a recipe book, a lead magnet, a course companion, a coloring book or a short novel) and create-ebook saves the idea, the format, the language and any outline you agreed on. A card shows the book and a button that opens it on create-ebook.com, where you sign in, check and edit the chapter plan, and the chapters are written one by one with a cover. Books are exported as PDF, EPUB and DOCX, with a print-ready paperback interior and cover for Amazon KDP. Works in English, French, Spanish and Portuguese. The app only receives the book idea and outline you share for this purpose, never your conversation; the writing itself happens on create-ebook.com.

Creative Cult
By Creative Cult
Creative Cult is a players-first games publication. Its connector answers questions about how players received new video games from Creative Cult's own research. For each game it follows, Claude gets the share of player reviews that recommend it, counted daily and dated, what players praise and criticise in their own reviews, who the game suits, answers to common questions, and numbered sources. Claude can also read the release calendar for any month and each month's new games ranked by the share of players who recommend them. Creative Cult never uses critic scores or press coverage. Every figure links to its page on creativecult.digital, so readers can check the source. Five read-only tools: search_games, get_game, get_release_calendar, get_best_of_month and list_research. No account or sign-in.

Croisa
By SORAWEBS, INC.
Create, edit, and host multilingual websites directly through chatting with ChatGPT. Ask ChatGPT to create your pages in your native language, and Croisa can translate them into the languages on your site, with localized URLs and language routing. A visitor who cannot read your site does not become a customer. If you run a restaurant, a salon, a contractor, or any local business where people speak more than one language, a menu, a price list, your hours, and your address in only your language sends everyone else to a competitor they can understand. The next change is the expensive part. A new dish, a new service, a holiday schedule, or a new price makes the other language wrong unless you rewrite it, hire a translator, or keep a second site. You write it once, in the language you already use with ChatGPT. Croisa can update your other site languages from that change. Most owners do not have a web person anymore. The site was built once and the login is gone, or there is no site at all, only photos and a phone number. You should not have to learn a builder or start a website project. Describe the business in the chat. Croisa creates the pages and hosts them. If you already have a site and it is stuck in one language, bring it to Croisa. Make it bilingual, put it on your own domain, and let people contact you in the language they actually read. When someone looks you up in their language, each language has its own URL, and they land on the one that matches them.

Crumb
By Kitty Parke
On the Household plan, anyone in your household can connect Claude to Crumb. Claude can then read your household’s recipes, meal plan, shopping list and kitchen, so it can plan meals from what you have and the diets people share, and add them to your plan and shopping list. Can see: Kitchen, recipes, the plan, lists, all notes, and who’s eating, with diets and foods they won’t eat for those who share. Can add and update: Items on shopping lists, new event lists, dishes and who’s eating on empty meals, new recipes and recipe versions, and Kitchen items and amounts. Never: Deletes anything, edits recipes or saved guests, changes diets or people, or marks meals cooked. When Claude adds to a tab in Crumb, a card at the top of that tab says what it did. Tap Undo all to take it back. Each person chooses whether their diets and foods they won’t eat are shared. When it’s off, Claude isn’t sent anything about them, and Crumb still checks what Claude adds against their diets.

CueScout
By Telman Gadimov
CueScout checks how AI answer engines treat a website. Ask whether an AI search engine names your brand for a question a buyer would type, and CueScout runs that question once and reports back: whether the brand was named, whether its site was cited, which of up to three competitors came up, and the pages the answer was built from. Those pages are mostly reviews, comparison posts and "best tools" lists on other people's sites, so the list tells you where the answer is coming from. Four more checks look at the site itself and use no AI. One reads robots.txt and says whether the main AI crawlers are blocked, including by a catch-all rule nobody meant to write. Another runs eight readiness checks: crawler access, llms.txt, Organization and FAQ schema, canonical and meta tags, whether the copy is in the HTML or only appears after JavaScript runs, and whether there is an about page and a pricing page. The last two validate the JSON-LD on a single page and check that the sitemap can be fetched, parses, and is listed in robots.txt. If you track brands in CueScout, you can connect your account and ask about them directly. The app then reads what CueScout has already collected: how often AI answers named your brand and each competitor, your share of voice, the prompts you're missing from and who got named instead, what each engine actually said, the pages those answers cited, your To-dos in priority order, and your last site audit. Connecting is read only. The app can't change settings, add prompts, run checks or buy anything, and you can disconnect it in CueScout's settings. It's built for marketers, founders and SEO people who want a quick read on AI search in the middle of a conversation. The five checks above work without an account. What it can't tell you: the visibility check asks an engine through its search API, not through a consumer app, so no account history, memory or location shapes the answer. One question gives one answer. A brand missing from one phrasing can show up in the next, so read a single result as one datapoint rather than a score. The site checks only read public pages and never change anything. Visibility checks have a daily limit shared by everyone using the app.

Cupid
By Playful.AI, Inc
Cupid is an interactive rom-com you play in ChatGPT. Set in the five beautiful boroughs of New York City, you take on the role of Cupid, the divine matchmaker, guiding a Mortal you choose through a first date with a Match you pick. Every character runs on astrology as its emotional framework: they have different professions, obsessions, hang-ups and astral influences that shape how they flirt, fight and fall in love. An AI narrator, a celestial voice you suspect has spent the last millennium on the Upper West Side, guides you through the critical moments. Your job is the first date: four short scenes, each ending in a choice for you to make. Every choice moves the story and the score. You can continue if you'd like, and when you've had enough, the Fates decide how it ends. Season One: thirty-six New Yorkers, three matches each, and you on the arrow. The characters and their stories are fiction. The romance stays PG-13. Astrology is part of the fun, not a forecast. Cupid needs no account and keeps no story: every game starts fresh. It keeps pseudonymous play records for analytics, as described in our privacy policy.
