Same person across channels

Where this stands Coming

This arrives together with WhatsApp and email. The matching rules below are already built and tested; the screens that show and confirm a match are not in your build yet. Today every Telegram chat is its own deal, and you'll see nothing of this.

Why it matters

Dana asks for pricing on Telegram, you send the proposal by email, she answers on WhatsApp. That's one deal. If Corner saw three, you'd get three sets of nudges, and the one on the channel she just used would be right while the other two nag you for nothing.

So the same person on Telegram, WhatsApp and email becomes one contact, and when it's the same deal, one deal with every conversation linked to it. Whose move it is then counts across all of them: answer her by email and the Telegram nudge clears too.

How Corner decides it's the same person

The rules are fixed and written down. The AI never merges anyone. Only an exact match acts on its own; everything else asks you first.

Exact match: joined by itself

Two contacts share an email address, a phone number, or a Telegram username you confirmed. They become one, and you can undo it.

Evidence: asks you

Something in a message points to the other contact. Her email signature says t.me/dana_k, or she writes “send it to dana@acme.com” on Telegram. You get a Same person? card with the reason in plain words.

Same name: asks you, gently

The same full name plus something that backs it up, like the same company or an email domain that matches it. Only for contacts you already have a deal with.

Some things never merge:

• Your own addresses and accounts.
• Two people who each have a direct chat with you on the same account. Two Telegram users are two people.
• Someone you only see in groups is never merged by itself.
• Pairs you said Not the same to. They aren't suggested again unless an exact match turns up.

Addresses and handles found in messages are only read from what they write to you, never from your own messages. Phone numbers only count in international form, starting with + or 00.

What happens to the deals Coming

• If at most one of the two has an open deal, the other conversations simply join it. No AI needed.
• If both have open deals, Corner asks before merging them, because two deals with one person can be two real projects.
• A new email thread from someone with exactly one open deal is added to that deal, and the deal panel says so with an undo.

Undo and unmerge Coming

An automatic join can be undone from the deal panel for 7 days. After that, and for good, Settings > Privacy > Merged contacts has Unmerge. You can also link a conversation to a deal by hand, or move one out into a new deal of its own.

Forgetting a conversation also deletes any address or handle Corner found in it, and any suggestion that came only from it.
