She asked for pricing 2 days ago.
“Can you send pricing for 12 seats?”
Your deals live in your chats. Corner won’t let them go quiet.
Corner reads your Telegram, builds your pipeline by itself and taps you on the shoulder when someone’s waiting on you. You still write every word.
Corner is in private beta. Ask Elmir or C for an invite.
Live demo. Try the buttons on the card.

Inbox zero for deals. Nobody’s waiting on you.
Demo data. Every name and company on this page is made up.
Most deals die of silence.
Nobody said no. Somebody forgot to write back.

Gone quiet
-
Your pipeline is scattered across 200 chats.
Deals sit between family chats and a group with 312 unread. The one that matters scrolls away by lunch.
-
The CRM wants data entry.
Nobody does data entry. So the CRM lives in a tab nobody opens, and it has no idea what happens in Telegram.
-
Reminders don’t know what was said.
A reminder can’t tell who owes the next message, or that you promised the deck on Monday.
“Let’s say I have a pending sale with Elmir. It continuously goes through my chats and says ‘yo, you have not written to Elmir in 5 days, here is the window, follow up now’. … I can imagine every salesperson I have ever had, including myself, needs this.”
From install to inbox zero for deals.
-
Connect Telegram.
Scan a QR code from Telegram’s Devices screen. Your chats sync to this computer, encrypted.
-
Get your pipeline in 60 seconds.
AI reads your recent chats and finds the deals. You flick through them: J to track, K to ignore.
-
Get nudged, with a reason.
When a deal is waiting on you, a card appears in the corner of your screen. It says who, why and since when.
-
Reply, and it clears itself.
Open the chat, write back, send. The nudge disappears on its own. No boxes to tick.
-
Run a daily sprint.
Every morning, work through what’s pending, one deal at a time, until nobody’s waiting on you.
You set how hard it pushes.
Calm by default. Relentless if you ask for it. Working hours and quiet hours always win.
Standard
A card appears in the corner and hides after 30 seconds. If you ignore it, it comes back after 4 hours, up to 3 times a day.
Defaults: Monday to Friday, 09:00 to 19:00, at most 15 new cards a day. All of it is yours to change.
Corner never sends a message for you.
You write. You hit send. That’s the deal. It’s also why your account stays safe: automated sending is how Telegram and WhatsApp accounts get banned.
- Where your chats live
- Encrypted, on your computer. Nowhere else.
- Corner servers
- None. Your chats never reach us.
- What leaves your computer
- Text from the chats being analyzed, sent to Anthropic’s API with your own key. Chats you ignore aren’t analyzed after the first pass.
- Your say, per chat
- Exclude any chat and it’s never read. Forget a chat and its local data is deleted.
Telegram now. WhatsApp and email next.
- Telegram In private beta Official Telegram login. Read, track, reply from the chat pane.
- WhatsApp Next Read-only. Corner never sends from your number.
- Email After that Gmail and IMAP. The same person on every channel becomes one deal.
Built for follow-through.
-
It sits on top.
Keep Telegram, WhatsApp and email. Corner works over them, so there’s no new inbox to move into.
-
It holds you to it.
It counts the follow-ups you actually do. It will never do them for you.
-
You type nothing.
Stages, promises and who owes the next message come from the conversation itself.
-
Every nudge explains itself.
A rules engine decides when to interrupt, the same way every time, and the card always says why.
| Question | Corner | A CRM | A reminder app |
|---|---|---|---|
| Knows what was said | Yes | If you paste it in | No |
| Pipeline needs typing | No | Yes | There is none |
| Shows up when it’s your move | In the corner | In a tab | When you set it |
| Clears when you reply | Yes | No | No |

Questions, answered.
Does it ever send messages for me?
No. Never. Corner can draft a follow-up when you ask for one. You edit it and you send it.
Is it safe for my Telegram account?
Corner signs in with Telegram’s official login and never sends anything on its own, which is what gets accounts restricted. Sync runs at conservative rates.
Where are my chats stored?
On your computer, encrypted. We don’t run servers that hold your chats.
What does the AI see?
Text from the chats that look like deals, sent to Anthropic’s API for analysis with your key. Chats you ignore aren’t analyzed after the first pass, and excluded chats aren’t read at all.
Do I need my own AI key?
In the beta, yes: you paste an Anthropic API key. Without one, Corner still nudges on timing alone. A hosted option is planned so you won’t need a key.
What if it nags too much?
Switch to Gentle, set quiet hours, lower the daily cap, or mark a chat “not a deal”. That chat is never nudged again.
Which computers does it run on?
Windows first. A macOS build is on the way.
How do I get in?
Corner is in private beta. Ask Elmir or C for an invite.
Your move.
Someone in your chats is waiting on a reply right now. Corner makes sure it’s never for long.
