Honestly, the renewal increase is higher than we expected. I’m not sure I can get this approved.
I get it, especially after the scope change last quarter. Let’s work through the renewal over coffee near your office. Would Thursday at 3 or 4 work?
Knowledge Recalled: Sam’s scope changed last quarter.
Thursday: 3 PM or 4 PM free.

Absolutely, David. We agreed on $2,400 for the full package. Happy to get started.
Message
Use facts from your files.
A client asks for the agreed price. ToneBird finds it in your connected proposal and includes it in the draft.
You're right to ask again, David. I'm sorry to keep your team waiting. I'll get you a firm date by tomorrow.
On it. I'll have a date for you tomorrow. Thanks for the nudge!

How Tonebird helps every day.
Brooke Danielle Nelson@AiWithBDN
Tonebird remembers who you’re talking to and where you left off, then helps you reply in your own voice inside the apps you already use.
Kathia@TheKathAI
Tonebird adapting tone while keeping your voice is way more interesting than just making every reply sound “better.”
Nico@nicos_ai
Show me an AI tool that can understand why that paragraph needs to sound different depending on the person, and now I’m interested. That’s what stood out to me about Tonebird.
paula@paulai_
Tonebird’s relationship memory changes that dynamic. The person on the other side of the conversation becomes part of the context the AI can work with.
Mira Sterling@Chaemate_
The feature that made me stop wasn’t “AI writes replies.” It was the idea of the AI remembering the relationship behind the conversation.
SONIA@S0N_IA
I don’t need to leave the conversation, build a giant prompt, explain the backstory, then bring the output back.
Zarah@Ho_Neyy_
That’s one thing I like about Tonebird. It seems to understand that a reply doesn’t exist in isolation.
marcus@marcusyul
Tonebird is interesting because the product is designed around keeping that context available, so the assistant can help without requiring a full briefing every single time.
fred@heyfredds
Help with wording and context kills some of the friction that makes me keep postponing.

What does ToneBird do?
ToneBird drafts replies inside the apps you already use. It brings in the person, earlier conversations, and relevant facts so you can pick up where you left off.
Does it work on Mac and Windows?
Yes. Downloads are available for both macOS and Windows.
Choose your version on the download page.
Which apps can I use it in?
ToneBird works beside readable reply fields in apps such as Gmail, Slack, WhatsApp, iMessage, Discord, WeChat, Lark, and X.
Support depends on the app and the field you are typing in. Some fields may not be readable.
Does ToneBird send messages for me?
No. Insert places the draft in your reply box. It does not send it.
You review the message and use your app’s own send button.
Can my conversation reach an AI provider?
Yes. The model provider receives the context and instructions needed for your reply.
With a managed model, ToneBird forwards the request. With your own model key, writing requests go directly to that provider. See providers and data handling.
