Situation: haven't replied to your friend in three weeks.
Hey — sorry I've been distant. How are you?

The four messages
everyone puts off.
Spectrum is trained on the shape of the messages a busy operator actually sends. Four canonical situations; five tones apiece; short, medium, and long.
Difficult conversation
The talk you've been putting off with someone on your team.
Time for us to sit down properly on Friday. There's something on my end I've been meaning to get in front of. Coffee, not calendar.
Apologies
The one you owe from Sunday but haven't written yet.
I owe you an apology for how Sunday went. You were right to be upset, and I made it harder than it needed to be. Whenever you're ready.
Fundraising updates
The quarterly note to your existing investors.
Q3 update — the good, the ugly, the ask. TL;DR: revenue up 41% MoM, churn ticked to 4.1%, we need one warm intro. Full note below.

Free tier: five drafts per hour, per IP. No account needed. Same input always returns the same drafts, so you can share a permalink with a friend and get a second opinion.
Softens edges. Good for friends and family.

The people who write
for a living.
I use Spectrum for the follow-up emails I put off for weeks. It sends what I would have sent, if I'd had thirty minutes.
Sana K.
Founder, Northline
The tone control is the whole thing. I don't need "warm" for my accountant, I need "chase-up" for my accountant. Spectrum gets it.
Marco V.
Operations lead, Meridian
I bought Pro after using the free tier for a week. I sent it to my board in Slack, unpaid. That says it all.

Frequently asked,
honestly answered.
Pro users can save custom tone presets — three examples of a message you've sent that you like, and Spectrum will mimic that pattern on future drafts. The model is not fine-tuned on your data; the presets are used as few-shot examples per request.
