From mother-in-law · 2:14 pm

Oh, don't worry about Sunday. I'll just eat alone again. It's fine. ❤️

Guilt trip

She doesn't want to be alone — but she also wants you to feel bad about it. The "❤️" is the trap.

Keep the peace Aww, I love you. We can't make Sunday but let's plan for next weekend — your call on the time.

Set a boundary We're not free Sunday, but we'd love to see you another day. The guilt isn't going to change our plans, though.

Nuclear Mom, I love you, but the eating-alone-again card is wearing thin. Want to actually pick a day or keep doing this?

The texts you've been ignoring for two days

Some messages aren't about what they say.

They're loaded with subtler, history, expectation. You read it, your stomach drops, you put your phone face-down. Sound familiar?

"Must be nice to have all that free time. Wish I could just take a vacation whenever."

— Mom

"Just thinking about you ❤️ Hope work is going better this year."

— Mother-in-law

"K."

— Sister

How Subtler works

Three replies. Pick your energy.

Most apps just generate one reply and hope. Subtler gives you three calibrated options every time, so you can match the moment instead of just sending the AI's first guess.

Keep the peace

Defuses without engaging the bait. Warm, brief, doesn't capitulate but doesn't fight. The "I see you, I love you, I'm not biting" reply.

Set a boundary

Calm, clear, names the dynamic gently. Doesn't apologize for existing. Doesn't attack. The "this is the line" reply.

Nuclear

The unfiltered version — what you actually want to say. Read it. Feel it. Send a different one. (Or don't.)

Three steps

Screenshot in. Reply out. That fast.

Drop the screenshot

Or paste from clipboard, or just type the text. Pick who it's from — Mom, MIL, sibling, dad. Pick your vibe.

See the subtler

What they actually mean. The move they're making. The dynamic underneath. In plain English, no therapy-speak.

Pick a reply

Three calibrated options. One tap to copy. Send the one that fits — or edit it first. You stay in charge.

Pricing

Less than one therapy copay.

The things you'd ask before handing over your group chat.

Is this just ChatGPT with a prompt?

No. We use Claude (better at reading social subtler, way safer with sensitive content) and we've spent months tuning the prompt against real family text scenarios — guilt-as-currency dynamics, sibling roles, in-law power moves. The "three replies" structure is the product, not just an output format.

Where does my screenshot go?

Straight to Anthropic's API — never to our servers, never stored anywhere by us. Your message history lives only in your browser's local storage, on your device. Clear it any time from Settings.

Will I become emotionally dependent on an AI to talk to my mom?

You already have an internal coach helping you reply to loaded texts — friends, your spouse, the group chat where you screenshot it. We're just faster and don't get tired of you. Most users tell us they need it less over time, not more, because they start spotting the patterns themselves.

Can I use Subtler for non-family stuff?

Today it's tuned hard for family texts — that's where it's sharpest. Workplace and dating modes are in beta with a wait list (drop your email below).

What if the "Nuclear" reply is too mean?

It's labeled "don't actually send this — catharsis, not strategy" for a reason. Read it. Feel the satisfaction. Then send "Keep the peace" or "Set a boundary." That gap is the point.
