Group chat analysis: what happens to everyone else
What Portraitor returns from a group thread, what it costs when several people are in it, and what its privacy policy says happens to the participants who never used it.
Group chat analysis reads one participant at a time, and the Portraitor home page states the counting rule plainly: one person is one portrait, two people are two, a group of five is five. The privacy policy says every participant’s name is replaced with an anonymous placeholder on your own device before any text is sent.
Two questions decide whether group chat analysis is any use to you. What comes back when a thread has six people in it rather than two, and what happens to the people in it who have not used the service themselves. Both have published answers, so what follows quotes the two live pages that carry them rather than describing them from the outside.
What comes back from a group thread
The home page describes four lenses on the same conversation: relationship context, Big Five (OCEAN), Transactional Analysis and change over time. The first of the four is the one a group thread changes. Relationship context is reported as one label with a confidence score and a short justification, and one of its five possible labels exists for group threads specifically. The page describes it as “group threads where several relationship types run at once”, named rather than forced into one label.
The Big Five lens is reported as a lean per trait and never as a score out of ten, each with a frequency label and a confidence score. The Transactional Analysis lens covers five ego states, and the home page says it reports which states dominate in calm exchanges, which appear under tension, and which show up when someone talks about people who are not present. In a group thread that last one covers a large share of the messages. The change over time lens splits the material into phases and names the points where something turned.
The privacy policy lists what the analysis infers and says each inference carries an estimate of confidence. It also says the inferences are delivered to you alone, that Portraitor does not retain them, that nobody there can read them, and that no decision about anyone is ever made from them by Portraitor or by any system it operates. The full list is on the Portraitor privacy policy, and what a portrait contains for a single conversation goes through the same output in more detail.
What happens to the other people in the thread
The privacy policy has a section headed “The other people in your conversation”, which is the part worth reading before uploading anything with five names in it. It says their names, email addresses and telephone numbers are removed on your device before anything is transmitted, and that the list matching each placeholder back to a real detail never leaves your device. It says Portraitor holds no record of them, the portrait is delivered to you alone, and nothing about them remains on its systems once the portrait has been produced.
Three mechanical details sit alongside that. If the masking step does not complete successfully, the policy says no data is transmitted and the payment is refunded automatically. Chat exports often carry photographs, videos and voice recordings, and the policy says the service never opens them and never transmits them, reading only the written messages. Conversation text is never written to the database, the backups or the logs, and a very large upload that is abandoned part way becomes unreadable after fifteen minutes.
The limit on all of this is stated on the same page, and it is the sentence a group thread turns on. Masking removes who is speaking, not what was discussed. In the policy’s own words, if the people in the conversation talked about their health, beliefs, relationships or sexuality, those passages travel to the analysis provider inside the anonymised text, with no name attached to them. In a group thread that caveat runs across every participant’s messages rather than one other person’s.
What a group chat costs
The home page publishes two prices. A single portrait is $10, with no account and no renewal. A Pass is $19 a month for 10 portraits, which refill on the renewal date, and unused ones are lost rather than carried over. Against that allowance the counting rule is the one quoted at the top: one person is one portrait, two people are two, a group of five is five.
So a five person thread read in full is half of a month’s allowance, and a ten person thread is all of it. A Pass can be shared, and the home page is direct about what that means: everyone draws from the same pool of 10 a month, so sharing costs nothing extra, but anyone you share with is spending your portraits. How free chat analysers differ from paid ones sets out what the price is buying in the first place.
Thread length, and when to split one
Length is where a group thread gets practical, and the home page puts numbers on it. It says there is no hard limit, that the fastest result comes from keeping a conversation between 100,000 and 200,000 characters, roughly a few months of an active chat, and that longer still works or can be split, with each part counting as a separate analysis. The second half of that sentence is the one to plan around, because splitting a long thread into three spans multiplies what it costs against the allowance.
The platforms the uploader takes are WhatsApp, Telegram, Messenger and Instagram. The home page says a WhatsApp export gives a .txt or .zip file, Telegram from the desktop app gives a .json file, and Messenger and Instagram each give a .zip. The uploader accepts .txt, .html, .json or .zip. If the thread you have in mind is on Telegram, exporting a Telegram chat history covers getting the file out first.
Not every group chat qualifies. Google Chat is not one of the four platforms the uploader takes, so a Google Takeout archive has nowhere to go here, even though the export itself is covered in the guide to exporting Google Chat messages. That is a dead end rather than a workaround.
Permission, which a group thread makes a real question
The privacy policy states that before you pay, you confirm that you have permission to analyse the conversation, and that the Terms of Service set out what that confirmation requires of you. A group thread is where that sentence stops being a formality, because the confirmation covers everyone whose messages are in the file rather than one other person.
This page does not tell you whether you have that permission, and it is not the sort of question a web page can answer for you. It is written down in the Terms of Service linked from the privacy policy, and that is where the actual wording is.
Whether it is worth it for you
Three cases where it is not. If what you want is a verdict on one person in the group, the policy is explicit that no decision about anyone is made from the inferences, and the output is a description of patterns in the conversation rather than a finding about a person. If you need the real names to appear in the result, they will not, because they are replaced before the text is sent. If your group chat lives on a platform outside the four listed above, the uploader will not take it.
One caveat that belongs on any page making privacy claims. The Portraitor site itself runs Google Analytics, which sets cookies, and the privacy policy says so and offers an opt out. The same policy’s table of who receives what lists analytics as receiving pages visited, referring site, device and browser type and approximate location, and states “never your conversation”. The privacy argument above is about the conversation, not about the website.
The case where it is worth it is narrow and specific: a long group thread you were part of, on one of the four supported platforms, where what you want is a written read of how the conversation actually ran rather than a verdict on anybody in it. The four steps are on the Portraitor home page, and the masking the policy describes happens before any of that text leaves the browser.
Whether it is safe to hand a conversation over in the first place is a separate question, answered from the same two pages in is it safe to upload your chat history.
The same choice points the other way just as easily. If the person you pick in step 2 is yourself, your own name is masked on your device like everyone else in the thread, and the whole inference register is applied to you. What picking yourself changes goes through it.
The same question across five services, read side by side, is in how five chat analysers handle the person who did not upload the chat.
Frequently asked questions
Frequently asked questions
Does analysing a group chat cost more than a two person chat?
Yes, in proportion to the number of people. The home page states the counting rule as one person is one portrait, two people are two, and a group of five is five, so a five person thread uses five of the ten portraits a $19 monthly Pass carries.
Do the other people in the group need to use Portraitor?
No. The privacy policy has a section for exactly this case, and says the other participants have not used the service themselves, that their names, email addresses and telephone numbers are removed on your device before anything is transmitted, and that no record of them is kept. It also says that before you pay you confirm you have permission to analyse the conversation, and that the Terms of Service set out what that confirmation requires.
Does masking remove what the group talked about?
No. The policy is specific that masking removes who is speaking and not what was discussed, and that passages about health, beliefs, relationships or sexuality travel to the analysis provider inside the anonymised text with no name attached.
What happens to the photos and voice notes in a group export?
The policy says the service never opens them and never transmits them, and that only the written messages are read, on your device, with only their masked text sent on.
Which group chats can I upload?
WhatsApp, Telegram, Messenger and Instagram, according to the home page. A WhatsApp export gives a .txt or .zip file, Telegram from the desktop app gives a .json, and Messenger and Instagram each give a .zip. The uploader accepts .txt, .html, .json or .zip.
How long can a group thread be?
The home page says there is no hard limit, and that between 100,000 and 200,000 characters gives the fastest result, which is roughly a few months of an active chat. A longer thread can be split, and each part counts as a separate analysis.
What the masking covers, and what it leaves in place, is set out in the same policy. Does a chat analysis remove names reads both halves of that sentence.
Both of the pages quoted here are public and both are linked above, so none of it has to be taken on trust.
