A WhatsApp chat analyzer reads an exported WhatsApp conversation and describes the patterns in it. Portraitor writes a portrait of how one person communicates: tone, relationship, traits and change over time. It describes message patterns, not a diagnosis.
Open the chat in WhatsApp, choose Export Chat, and pick Without Media. Then drop the saved file into the upload box.
Open the chat, then tap the contact or group name at the top.
Scroll to the bottom and tap Export Chat.
Choose Without Media.
Tap Save to Files. iOS wraps the chat in a small .zip.
On Android: three dots, More, Export chat, Without media.
The WhatsApp analysis uses four lenses: relationship context, Big Five personality traits, Transactional Analysis and change over time.
Established before anything else is interpreted. The same sentence means one thing from a manager and something else from a partner.
One label with a confidence score and a short justification, drawn from topics, terms of address and shared context, alongside an approximate positive / neutral / negative split of the whole conversation.
The standard trait model in personality research. Each of the five is reported as a lean, never as a score out of ten.
A direction per trait, with how it helps and where it creates friction. Each carries a frequency label and a confidence score.
Five ego states. The voice someone uses on an ordinary day is rarely the voice they use in an argument.
Which states dominate in calm exchanges, which appear under tension, which show up when they talk about people who are not present, and whether the balance shifts across the timeline.
A conversation is not one snapshot. The material is split into phases and the moments where something turned are named.
A before-and-after description for each turning point, and whether the change was a short spike or became the new baseline.
Two things people ask first: group chats and privacy.
Yes. Export the group chat and choose the one person to analyze. Before you pay, you confirm you have permission to analyze the chat.
You choose the person in step 2 of the upload.
Names, emails, phone numbers and addresses are masked in your browser before anything is sent. Photos, videos and voice notes are never opened or sent.
Your saved portraits remain in your own browser. Read the Privacy Policy.
Yes. Portraitor reads Instagram, Messenger and Telegram exports too. Export, upload, pick a person.
A chat log covering several years between Daniel and one other participant, ranging over everyday updates, professional pressures and ambitions, close relationships, family matters, and financial strain.
Based solely on the supplied written material. It does not constitute a clinical evaluation, and interpretations are probabilistic.
Inferred Relationship Type: Close friendship / supportive confidant.
Confidence: 85%
Justification: Sustained openness and mutual support; both discuss relationship difficulty, work stress and money in detail.
Approximate Percentages of Exchanges: positive 55-65%, neutral 20-30%, negative or tense 10-20%.
General Interaction Climate: Largely supportive, with external stressors introducing shared tension rather than conflict between the two.
Consistently responsive to the other participant’s emotional state, turning concern into practical help rather than reassurance alone, and shares his own difficulties in return.
Real people. Real texts. Real change.
What I love is the privacy-first approach. You can ask the questions you’d never normally ask AI, without compromising your privacy. And for me, it gives me insights that I can actually use.
It was really interesting to understand and see what patterns were in the conversation. Once I could see the patterns, it became really eye-opening for me and for how my relationship works.
The instructions were very clear and easy to follow, especially for someone who isn’t very technically minded.
Quick answers about this tool.
No. One portrait is $10, with no account and no renewal. The Pass is $19 a month for 10 portraits.
Identifying details are removed in your browser before anything is sent. Photos, videos and voice notes are never opened or sent.
It reads patterns in the written messages, and each finding comes with a confidence score. It is not a diagnosis or advice.
You can paste a chat into ChatGPT, but it sees names and numbers as they are. Portraitor masks identifying details in your browser first, then reads the chat through four fixed frameworks, so every portrait has the same structure.
There is no hard limit. A few months of an active chat gives the fastest result.
Yes. After you choose the person, you pick the time period, such as the last three months.
Practical posts for spotting patterns and choosing a next step.
