Three New Tools: SaaS Cost Calculator, Real PDF Redactor, In-Browser AI Background Remover

Most free tool launches are just “here's a free version of something everyone already has.” This batch is deliberately not that. Each of these three tools does something the other free options don't do well — or at all. Below: what each one is and the specific gap it fills.

1. SaaS Cost Calculator

What it does. Pick the SaaS tools your team uses (40+ supported across tasks, chat, notes, time tracking, design, video, drive/email, scheduling, CRM, automation, HRMS) and your team size. The calculator adds up the annual cost and shows it next to Pulsyr's flat plan, with the savings spelled out as a percentage.

The gap it fills.Every team paying $5k+/year on SaaS has, at some point, tried to add up “what are we actually paying for all this?” The exercise is annoying — different billing pages, different per-seat counts, different annual-vs-monthly toggles, often a spreadsheet involved. The result, when you finally see it, is usually a number that makes someone say “wait, really?”

Try it. /tools/data-tools/saas-cost-calculator. Defaults to a typical 20-person stack (ClickUp + Slack + Notion + Toggl + Google Workspace + Zoom) so you see a realistic number out of the gate.

2. PDF Redactor — Real redaction, not a black rectangle

What it does. You drop a PDF, drag rectangles over confidential text, and download a redacted version. Nothing groundbreaking — except that most free PDF redactors don't actually redact anything.They draw a black rectangle on top of the existing text. Anyone can copy/paste from the “redacted” PDF and read it.

How this one is different. On save, each page is re-rendered as a high-resolution image, then the redaction rectangles are painted on top of that image. The output PDF contains only the rasterized images — the original text layer is gone. Truly redacted, not just visually covered.

The trade-off.The output PDF is no longer searchable text — it's effectively a scanned document. That's the price of real redaction; a tool that preserves the text layer is one that hasn't actually redacted anything. We surface this trade-off explicitly in the UI so you know what you're getting.

The privacy story. Both the rendering (pdf.js) and the redaction (pdf-lib) run entirely in your browser. The PDF never leaves your device. Verifiable in DevTools → Network: zero requests during the redaction step.

Try it. /tools/pdf-tools/pdf-redact. Works for legal documents, HR letters, medical records — any case where you need to share part of a PDF without exposing names, account numbers, or other personal data.

3. AI Background Remover — No upload, ever

What it does.Drop a photo, get a transparent PNG with the background removed. Same output as remove.bg or photoroom.com, except: the AI model runs entirely in your browser. Nothing is uploaded. Nothing is metered. No watermark, no signup, no “upgrade for high-res.”

How it works. Pulsyr loads the MODNet segmentation model into your browser via @huggingface/transformers on first use. Inference runs on WebGPU when your browser supports it (most Chromium-based browsers in 2026), with WebAssembly as a fallback. The image is read locally, processed locally, and the resulting PNG is generated locally — at no point does the file leave your device.

First-run cost.Loading the model is a one-time ~50 MB download from HuggingFace; it's cached in your browser's IndexedDB after that. Subsequent runs are essentially instant.

The gap it fills.“Free” background removers usually mean “free up to N images per month, then we charge,” or “free at low resolution, paid for full quality.” remove.bg is roughly $9/month for 40 images. PhotoRoom is $12/month. The actual model that does this work is open-source and runnable on a laptop CPU in seconds — there's no technical reason it should be metered. So we made the unmetered version.

Try it. /tools/image-tools/background-remover. Best results on photos with a clear subject (people, products, pets). Hair, fur, and glass edges may need touch-ups in your image editor — same as every other tool in this category, paid or free.

What changed under the hood

Three sub-fixes shipped alongside the new tools that improve the rest of the suite too:

• CSP for in-browser AI.Pulsyr's strict Content-Security-Policy now permits the specific things transformers.js needs (WebAssembly execution, blob: worker imports, fetches to HuggingFace and jsdelivr). Without these, “Failed to fetch” errors haunt every browser-based ML tool — they're no longer haunting ours.
• pdf.js worker URL. Switched from unpkg.com to jsdelivr (already in our CSP allowlist). Side benefit: every PDF tool — Merge, Split, Rotate, Crop, etc. — was silently broken under the strict CSP because unpkg was blocked. They all work now.
• React 19 title warnings. Cleaned up across BlogPostLayout, /tools/[category], /careers, /meet — React 19 only accepts a single string in <title>, not an array of children. Console is now quieter.

Where this lands

Pulsyr now ships 28 free browser-based tools at /tools — PDF, image, sheet, and website utilities. None of them require an account. They exist as a separate offering from the main Pulsyr work dashboard, but they sit in the same product brand: a complete platform for small teams that doesn't charge per seat.

Coming up — likely the next batch of unique tools we've drafted: GST invoice generator (India-specific compliance), in-browser image upscaler (same architecture as the bg remover), broken-link checker (crawls a page, lists every dead link). If there's a tool you reach for repeatedly that always involves signing up for something, message us — that's the kind of gap we like filling.
