ApplyOnce – Local-first job application autofill that reads scanned resumes

Formerly codename FastApply; renamed after ASO research (fastapply.co is an existing competitor — see docs/ASO-REPORT.md). Internal storage keys and the IndexedDB name keep the old identifier for data compatibility.

One-click job application autofill, deterministic-first, local-only. See PLAN.md

for the full design and CLAUDE.md

for agent/contributor rules.

Install: Chrome Web Store · Firefox: build from source (npm run build:firefox

, see "Load in Firefox") until the AMO listing is live. Version 0.2 adds layout-aware resume parsing, on-device OCR for scans, resume re-import, and an optional on-device question classifier (PLAN.md Part 9).

• Open the side panel (click the ApplyOnce toolbar icon), complete onboarding (drop your resume, review the extracted profile, set explicit answers).
• Open a job posting (Greenhouse / Lever / Ashby / generic form) → Scan this page→ review →** Fill**.

The extension never submits an application — you always click submit yourself.

npm run build:firefox

→**Load Temporary Add-on…**→ selectdist-firefox/manifest.json

.- Firefox treats MV3 site access as optional: open the ApplyOnce sidebar → Settings→** Allow ApplyOnce on all sites**(or grant it underabout:addons

→ ApplyOnce → Permissions). Auto-detection is silent until then. - Toolbar icon opens the sidebar; the in-page widget's panel button opens the panel in a tab (Firefox only allows opening the sidebar from a direct user gesture).

Differences from Chrome are all runtime feature-detected in src/shared/platform.ts

: no offscreen document (resume parsing runs in the background event page), sidebar_action

instead of side_panel

, and Firefox's install-time data-collection consent gates telemetry. See docs/FIREFOX.md

for the AMO submission steps.

src/content/

— scanner (shadow-DOM aware, radio grouping, widget hints) + filler (native setters, DataTransfer file attach, widget playbook). Only code with page-DOM access; injected on demand viaactiveTab

.src/shared/

— pure logic: zod schemas, canonical field ontology, matching cascade (ATS adapter rules → autocomplete tokens → label lexicon → saved answers exact/fuzzy → abstain), confidence + hard risk gates, CV text parser.src/storage/

— Dexie vault (profile, documents, saved answers, fill log), optional passphrase AES-GCM encryption, JSON export/import.src/background/

— stateless MV3 service worker: routing, job ids inchrome.storage.session

, offscreen lifecycle.src/offscreen/

— PDF.js / Mammoth resume parsing.src/sidepanel/

— React UI: onboarding, profile vault, review-and-fill loop, settings, diagnostics.fixtures/

+evals/

— the eval corpus is the product spec. Launch gates: detection recall > 0.95, mapping precision > 0.98, zero forbidden fills.

• OCR for scanned PDFs is stubbed (paste-text fallback instead) until Tesseract traineddata can be vendored into the package — no runtime downloads are permitted.
• Fixture corpus currently holds 4 synthetic pages modeled on real ATS DOM. Replace/extend with SingleFile captures of real postings (PLAN.md Phase 0 target: 40 pages) before trusting the accuracy numbers.
• Live-browser e2e scripts live in e2e/

(verify-extension.mjs

for Chromium,verify-firefox.mjs

for Firefox); they run against the synthetic fixtures. Filler behavior on real ATS widgets still needs the 10-application live gate (PLAN.md Phase 4) before launch.
