Proofsmith Labs builds focused browser extensions for analysts, developers, consultants, sellers, writers and support teams. Each tool does one job well — and every one of them keeps your data on your own device.
Ten extensions, one shared standard: local-first storage, no accounts, no telemetry. Each one has a free tier you can actually use.
Capture charts from any dashboard, annotate, and turn them into polished reports. Your metrics, one click from screen to slide.
Pro: $8/month or $69/yearOverlay your design on the live page, spot mismatches, measure gaps, and ship pixel-perfect front-ends.
Pro: $10/month or $79/yearClick any table on a page to grab it into a local library, then export to CSV or Excel — works with div-based grid layouts, not just <table> tags. Data never leaves your browser.
Pro: $8/month or $59/year Add to Chrome — free → Add to Edge — free →Fill a form once, pick any field in it, and FormSnap records the filled fields around it — bring your answers back on the same page in one click. Never submits forms for you.
Pro: $5/monthTake frame-accurate notes on videos: timestamped notes, frame capture, A-B loop. Built for film study and video essays.
Pro: $6/month or $49/yearSnapshot any page and re-check later — visual and text diffs highlight exactly what changed. Watch competitors, landing pages and the fine print.
Pro: $12/month or $99/yearTrack every job application in one kanban board. Save postings from any job page — JobPilot reads the structured job data already on the page, pre-fills the entry, and you pick the stage it's already at before saving. Keyword match, follow-up reminders included.
Saves from sites that publish structured job data — most major job boards (like LinkedIn, Indeed, Glassdoor and ZipRecruiter) and company career pages do. Not affiliated with or endorsed by any job board.
Job Search Pass: $29 one-time or $7/monthSnip charts and frameworks from any report into a searchable library. Rebuild 2×2s and funnels into pre-filled, editable PowerPoint slides — or turn a whole selection into a deck in one click.
Pro: $12/month or $99/yearKeep your story bible beside your draft: characters, timeline and foreshadowing tracked while you write in Google Docs.
Pro: $7/month or $59/yearType / in Gmail to insert reply templates with variables filled inline. Save minutes on every email — nothing is sent automatically.
Pro: $9/month or $69/yearThree rules that apply to every extension we ship.
Your snapshots, notes, documents and settings live in your browser — never on our servers. Most of our tools have no server at all.
We don't require sign-ups and we don't track you. Install, use, and the only thing we ever see is an email you choose to send us.
Every extension is genuinely useful for free. Pro plans unlock higher limits for people who rely on the tool daily.
