Use cases
Screen-sharing privacy for the way you actually work
Keep every video call professional
If you share your screen on Zoom, Google Meet or Microsoft Teams a few times a week, everything on screen is fair game the moment you hit share — a Slack notification sliding in, the subject lines in your inbox, a bookmarks bar full of half-finished side projects, the tabs you forgot to close. The usual advice is to tidy up beforehand, and it fails the instant something pops in mid-share.
BlurFirst lets you blur those spots once — drag a box over the notification corner, click the bookmarks bar, frost the email list — and they stay blurred for the whole meeting, even as the page re-renders. If something unexpected appears while you're already sharing, the panic shortcut (⌘⇧H / Ctrl⇧H) frosts the entire page instantly. Nothing you blur ever leaves your browser.
Incoming notifications, email subject lines, the bookmarks bar, unrelated browser tabs, calendar invites.
Demo code and dashboards without leaking secrets
Screen-sharing as a developer puts your editor, terminal and internal dashboards on display — and with them the things that should never be seen: API keys in a .env file, bearer tokens in a network tab, database rows full of real customer data, staging credentials in a config. One scroll into the wrong file during a standup or a pair-programming session and a secret is sitting in someone else's recording.
With BlurFirst you click the exact lines or panels that hold secrets — an env value, a token, a column of user emails — and they're frosted before you present. Box-blur covers a whole logs panel; element-blur hides a single value and a second click brings it back. Blurs persist per site, so your admin dashboard stays demo-safe every time you open it.
API keys, .env values, access tokens, customer PII in logs and databases, staging and production credentials.
Show the product, not the pipeline
A live demo is your strongest sales tool, but the CRM behind it is full of things a prospect should never see: other customers' names and logos, your internal pricing, the revenue and pipeline numbers on the dashboard. Spinning up a sanitized demo account isn't always practical, and one stray screen can quietly cost you the deal.
BlurFirst blurs the sensitive cells — the account column, the price field, the revenue widget — so you can demo in your real environment while every prospect sees a clean, focused walkthrough. Box-blur a table column once and it stays locked to that content as you scroll the list.
Other clients' names and logos, internal and list pricing, pipeline and revenue figures, CRM notes, deal stages.
One client never sees another
You serve multiple clients out of the same tools — the same project board, the same time tracker, the same inbox. The minute you share your screen with Client B, anything tied to Client A is exposed: their name, their deliverables, your rate card. Breaches like this are almost never malicious; they're accidental, and they still erode trust.
BlurFirst keeps them from happening. Blur the other clients' rows, your rates and unrelated project names before the call, and they stay hidden the whole time — the difference between looking buttoned-up and explaining an awkward leak.
Other clients' names and work, deliverables, your rates, unrelated engagements.
Record and stream clean
Tutorials, course videos and live streams are permanent — whatever's on screen gets published and stays published. Creators routinely catch DMs, email previews, an API key in a tutorial repo, or viewers' names in chat, then burn hours scrubbing it frame by frame in post (or worse, ship it).
BlurFirst blurs those areas before you hit record, so the capture is clean the first time. Frost your DM panel, your email tab, the key in your config. The blur is real pixels in the page, so OBS, Loom and every screen recorder capture exactly the blur you see.
DMs and chat, email, API keys in sample repos, personal and account info, viewer and donor names.
Help one user, expose none
Resolving a ticket over a screen share or co-browse session usually means your admin view is visible — and that view holds other customers' details, internal notes and account flags that have nothing to do with the person you're helping. Showing them is both a privacy problem and an unprofessional look.
BlurFirst lets you blur the surrounding tickets, the customer list and your internal annotations, so the session stays focused on the one account in front of you.
Other tickets and accounts, customer PII, internal notes and flags.
Teach without exposing students
Whether you're presenting a lesson in a classroom or over a call, sharing your screen can surface a roster of student names, the grades in a gradebook, and other students' submitted work. That's a privacy issue, and in many regions a compliance one (FERPA and similar rules).
BlurFirst blurs the roster, the grade column and the names on other submissions before you present, so you can teach from your real tools without exposing the class.
Student names, grades, contact info, other students' submissions.
Share a pipeline, protect the candidates
Reviewing candidates with a hiring panel often means sharing your ATS or a spreadsheet — which exposes the other applicants, their salaries and expectations, and notes that were never meant for the room. Candidate data is sensitive and, increasingly, regulated.
BlurFirst blurs the other rows, the compensation fields and private notes, so the panel sees only the candidate under discussion.
Other candidates, salaries and expectations, contact details, interviewer notes.
Present the numbers, hide the account
Walking a team or a client through a spreadsheet, an ERP or a banking portal puts account numbers, balances, payroll and vendor terms on screen — exactly the figures that should stay need-to-know. The analysis is the point; the raw ledger is not.
BlurFirst blurs the account numbers, the salary column and the balances you're not presenting, so you can share the story the numbers tell without exposing every line.
Account and card numbers, balances, payroll and salaries, vendor terms.
Pitch and present without oversharing
Board decks, cap tables, revenue dashboards and investor lists come out during pitches, all-hands and diligence calls — and not every number in the room is for every audience. A single visible figure can move a negotiation.
BlurFirst blurs the cap-table rows, the revenue you're not disclosing and investor names before you share, so you control exactly what each audience sees.
Cap table, revenue and metrics, investor names, board and financial details.
Protect patient information (PHI)
Telehealth and care coordination increasingly happen over screen shares, where an EHR, a chart or a scheduling view can expose patient names, diagnoses and other protected health information. In a HIPAA context, an accidental reveal isn't just embarrassing — it can be reportable.
BlurFirst blurs patient identifiers and the records you're not discussing before you share, so clinicians can collaborate without exposing PHI. Everything stays local in the browser — nothing about the chart is sent anywhere.
Patient names and IDs, diagnoses, other patients' records, contact details.
Protect unreleased and NDA'd work
Design tools mix clients freely — your Figma sidebar lists every project, and one open file can reveal another client's unreleased campaign or an NDA'd product. Walking through a portfolio live carries the same risk.
BlurFirst blurs the project list and the thumbnails you're not presenting, so you can show one client's work without leaking another's.
Other clients' projects, unreleased and NDA'd work, client names and logos.
Blur it before you share it.
