By the end

A companion that sounds like them — not a generic bot.

  • Voice trained from the real rhythm of your conversations — opener lines, slang, typos, tone
  • Relationship set (friend, mentor, grandparent, partner) so context stays correct
  • Private upload — used only for your companion, never shared or reused
  • First message that feels instantly recognizable
01

Get consent and export the chat

First, ask. A companion based on a real person should only exist with their awareness. Then, in your messaging app, open the conversation and use the built-in Export Chat option. Save the file somewhere you can grab from your phone.

Example export: a .txt file where each line starts with a name and timestamp, then the message. A .zip export works too — Soriz unpacks it and reads the text.
Pro tip: pick a thread with a range of moods, not just one topic. A few months of back-and-forth beats one long rant. Nuance needs variety.
02

Open Create Your Own in Soriz

Inside the Soriz app, tap Create Your Own. You'll see three starting points. Choose Import from chat history. This unlocks the upload flow and tells Soriz you're training from real conversation data.

Screenshot walkthrough: the Create screen shows three large tiles — Scratch · Real person · Chat import. Tap the third. A drop-zone appears.
03

Upload the chat export

Drag in the file or pick it from your phone storage. Soriz parses the chat locally, identifies the speakers, and asks which one you want the companion to sound like. It then surfaces their most-used phrases, emoji patterns, and the rhythm of how they text.

Example result: "We found 2 speakers in this thread. Which one is your companion?" — tap the name. Next screen shows a signature-phrases list like "okay listen," "chalo bata," "😭😭😭."
Pro tip: your file stays private. Soriz uses it only to shape voice for this one companion — it's not shared, not used to train other models. More detail on the privacy page.
04

Fine-tune personality

Soriz auto-drafts a personality summary from the chat — relationship type, general tone, recurring topics. Read it. Edit anything that doesn't feel right. You can also add "topics they'd care about" that didn't show up in the exported thread.

Example summary Soriz might draft: "Warm, a little sarcastic. Close friend who teases you about sleep. Often talks about gym, food, and weekend plans." You can add "books" if they were always recommending things but not in this thread.
05

Start talking

Pick an avatar, review the summary, tap Launch. Your companion's first message usually lands the vibe immediately — a hello in their actual rhythm. Chat memory starts fresh from this point and builds with every exchange.

Example first line from a companion trained on a college best friend: "oi. so u made a version of me now?? bold move lol. how are u actually doing this week 👀"
Pro tip: treat early conversations like you're catching them up. The more you share, the more the companion's responses stop feeling like "a model" and start feeling like "a person who knows you."

Common pitfalls · FAQ

Before you upload.

What chat formats does Soriz accept? +

Soriz supports plain text (.txt) and zipped chat exports (.zip) from most major messaging apps. If the file has your message lines prefixed with a name and timestamp, Soriz can parse it.

Is my uploaded chat private? +

Yes. Uploaded chats are used only to train the voice of your personal companion. They are not shared with other users, and are not used to train the foundation models Soriz runs on. Details on the privacy page.

Do I need consent from the other person? +

Yes — please ask. A companion based on a real person should only be created with that person's awareness and permission. Soriz is a tool for connection, not imitation without consent.

How much chat history do I need to upload? +

A few hundred messages is enough for voice patterns to emerge. More is better for nuance — ideally a long thread with varied moods and topics, not a short one-topic exchange.

Can I import chat history on the free plan? +

Chat import is a SorizPro feature — $9.99 per month with a 7-day free trial. The 20 built-in companions stay free on the basic plan.

Can I delete the uploaded chat file later? +

Yes. You can delete the source file from the companion's settings at any time. The companion keeps the voice pattern it already learned unless you delete the companion too.
