Choose Grey Mirror for a close examination of how a relationship changed: participant comparisons, repair patterns, turning points and the messages supporting them. MosaicChats presents sentiment, compatibility, personality and memorable exchanges alongside an AI coach. Both analyze exported conversations. Start by comparing the actual report with the questions you need answered.
The interesting part is what happened between the highlights.
The funniest exchange and the worst argument are easy to remember. The slow change in who reaches out, how long replies take or whether a disagreement gets repaired is harder to see. Grey Mirror follows those patterns through the history.
Ask the report a specific question. Where did effort become uneven? Did warmth return after conflict? Was a change brief or sustained? Grey Mirror brings the timeline, participant measurements and supporting messages together so you can examine the answer.
Read the data-use terms before uploading.
Grey Mirror states that uploads are not used to train models and publishes its retention and deletion rules. MosaicChats’ July 1, 2026 policy permits model improvement and research or business uses of anonymized, aggregated data. It also describes sharing derived traits through optional matching. Read both policies; “private” alone does not explain these differences.
Which one fits the question you are actually asking?
If you want a quick, shareable read of a chat, such as a compatibility score, personality types and your best moments, MosaicChats is designed for that. Its homepage advertises a free forever tier with no credit card, analysis in under a minute, and exports from WhatsApp, iMessage, Instagram, Telegram, Messenger and Snapchat.
If you want to know how the relationship changed and why, Grey Mirror is built for the slower question. It reads the whole exported history in order and shows who started conversations over time, how reply timing shifted, whether warmth came back after conflict, and the specific messages behind each finding. The complete report is $17.99 once, uploads are not used to train models, and you can preview your real story from your own upload before paying.

Frequently Asked Questions
Can MosaicChats analyze full conversation exports?
Yes. Its homepage lists exports from WhatsApp, iMessage, Instagram, Telegram, Messenger and Snapchat. This comparison does not treat MosaicChats as a screenshot-only tool.
How should I compare six dimensions with 30 analyzers?
Those are different units. MosaicChats groups its features into six advertised dimensions. Grey Mirror lists 29 default processing components and 1 optional component. Compare what the report measures and explains rather than dividing those counts.
Is MosaicChats free?
MosaicChats advertises a free forever tier with no credit card on its homepage. Grey Mirror previews your own relationship story free and charges $17.99 once for the complete report, with monthly plan optional.
Does either tool train AI on my messages?
Grey Mirror states that uploads are not used to train models. MosaicChats’ privacy policy, updated July 1, 2026, lists training and improving models using anonymized, aggregated data. Read both policies before uploading.
