Score a Reddit draft before you post it — then rewrite it and watch the number move.
One file · No install · Nothing leaves your machine
Try the hosted demo — the full UI running on a local heuristic in your browser. The real model judgement needs the tiny relay server this app ships with, so run it locally for genuine scores.
ThreadPulse is a single .mjs file that runs a tiny local server and a full app in your browser.
Paste a draft, and a TypeSafe model judges it with eight independent judgements — how strong the
title is, whether anyone has a reason to reply, how it fits the sub, and whether it reads as
promotion or will trip a moderator. It also rewrites your draft a hundred and twenty ways, built
from your own sentences, and shows you exactly what changed.
node threadpulse.mjs- Open http://localhost:8787
- Paste your TypeSafe API key — it stays in your browser and is sent only to TypeSafe
- Write a draft and hit Score this draft — or press Offline for a keyless local estimate

Switch to Rewrites and ThreadPulse assembles a dozen title treatments and ten body treatments from your own sentences, combines them into ~120 complete posts, ranks them, and re-scores the best three in full. Every version shows how much it changed, and a word-level diff shows exactly where:
Three change settings — Light touch, Rebalance, Rewrite hard — are thirds of the change actually achieved on your draft, so none of them is ever empty, and switching between them re-ranks instantly.
quality = 0.34·title + 0.34·reply + 0.32·fit
risk = 0.42·promo + 0.25·overpromise + 0.33·mod
score = quality × (1 − 0.55·risk)
Risk multiplies instead of adds: the thing that gets a post deleted is the thing that moves the number. If the model judges promotion above 0.78 or moderation risk above 0.68, the score is capped at 40 — a post likely to be removed should not be able to score 78.
- History keeps your last 30 runs on this device, so you can watch the score move as you tune
- Offline mode runs a local heuristic — no key, no network, rewrites included
- Ctrl+Enter scores the draft, 1–4 switches tabs
- Everything survives a refresh: your draft, key, and history live in
localStorage
Your API key, drafts, and run history never leave your machine — the bundled server only relays requests to TypeSafe's API and keeps no logs. Images stay in the page: only the description you write about them is scored. No analytics, no telemetry, no dependencies.
There's no hosted demo with real scores on purpose — TypeSafe's API doesn't allow browser calls from other sites (CORS), so the app needs its tiny server next to it, wherever it runs. Three ways to put it somewhere:
- GitHub Pages — the included workflow deploys the UI as a hosted demo that scores with the local heuristic. The page detects the missing relay itself and labels it; no key is ever entered there
- Render — the button below reads the included
render.yamland stands up a free service with the real model behind it
- Docker — anywhere containers run:
docker build -t threadpulse . && docker run -p 8787:8787 threadpulse
Any hosted copy holds no key and stores nothing — every visitor brings their own TypeSafe key, which stays in their browser exactly as it does locally.
