Gmail inbox triage bot: label, summarize and draft replies for review

What you end up with

You open your inbox to a short digest and drafts that are already written, then spend minutes approving instead of an hour sorting.

What you get

• One .md file with the complete Apps Script source (Code.gs) and a single config block
• Labels: Needs reply, FYI, Receipts, Newsletters, plus Draft ready and Seen
• Draft replies in your voice, with [CHECK: ...] markers where facts are missing
• Morning digest sent only to your own address
• SKIP_DOMAINS list so sensitive senders never reach the model
• Dry run mode, optional usage log sheet, uninstall steps and an instruction block for your AI coding agent

Who it is for

Founders, consultants and operators who get 50 to 300 real emails a day and lose the important ones under receipts, newsletters and threads that only need an FYI.

Works with

Solid chips: the agent is named in this listing's own tools list. Dashed chip: Runs on your own accounts.

Tools needed

Cost to run: Apps Script is free within Google's quotas. Model API calls are pay per use on your own key, and the script logs usage so you can see it.
Time to result: First digest the next morning

How it works

1. Create the script

   Open script.google.com, create a project and paste in the files from the template.

   Expected: The project saves with no errors.

2. Add your key

   Store the model API key in Script Properties, not in the code, and choose the provider in config.

   Expected: Running testConnection() returns a short reply from the model.

3. Dry run

   Run triage() with DRY_RUN set to true. It writes what it would do to the log without labeling anything.

   Expected: A log of planned labels you can sanity check.

4. Turn it on

   Set DRY_RUN to false and run installTriggers once.

   Expected: New mail gets labeled within 15 minutes, and a digest arrives each morning.

Preview

const CONFIG = {
  PROVIDER: 'anthropic',            // 'openai' | 'anthropic' | 'gemini'
  MODEL: 'REPLACE-WITH-CURRENT-MODEL-NAME',
  DRY_RUN: true,                    // log only, change nothing
  LOOKBACK: 'newer_than:2d',
  MAX_THREADS_PER_RUN: 30,
  DRAFT_REPLIES: true,              // drafts only, never sends to anyone
  DIGEST_HOUR: 7,
  SKIP_DOMAINS: ['yourbank.com'],
  LOG_SHEET_ID: ''                  // optional usage log
};

# Gmail inbox triage bot

PaperChase bot template, version 1.0. Google Apps Script, runs inside your Google account on a timer. Labels new mail, writes drafts for you to review and emails a morning digest to you only. It never sends anything to anyone else.

## What it does

Every 15 minutes it reads new inbox threads it has not seen, asks the model you choose to classify each one, and:

- applies one label: `Triage/Needs reply`, `Triage/FYI`, `Triage/Receipts` or `Triage/Newsletters`
- for Needs reply threads, saves a draft reply in your voice to Drafts and labels the thread `Triage/Draft ready`
- marks the thread `Triage/Seen` so it is never processed twice

Every morning at the hour you choose it emails you a digest: one line per Needs reply and FYI thread from the last 24 hours, with a link.

Nothing is archived, deleted or sent to other people. You can remove every label it created in one click.

## Contents

1. Before you start: data and quotas
2. Create the project and add your key
3. Source: Code.gs
4. Dry run, then turn it on
5. Tuning the classifier and your voice
6. Instructions for your AI coding agent
7. Uninstall

Worth knowing

• Email content is sent to the model provider you choose. Read their data use policy, and add sensitive senders to SKIP_DOMAINS.
• Apps Script has daily quotas. Very large inboxes may need a lower MAX_THREADS_PER_RUN.
• Drafts are drafts. Read them before sending; the bot can misread tone or miss context from a phone call.
