Write, don't fight the tool
A distraction-free editor that feels like Google Docs: headings, lists, word count, autosave. Students focus on writing, not on the software.
In-class essay exams
Locked-down essay exams,
with proof.
Students write timed essays in a clean, Google-Docs-style editor, reading only the PDFs and websites you approve. Meanwhile Weft watches the machine, the network, and the room, so a second laptop or a remote helper shows up red on your roster.

Why Weft
A real writing tool, inside a real lockdown.
Only the sources you allow
Attach PDFs and whitelist specific websites, an entire site or a single page. Everything else is blocked by the in-app locked browser.
Proof, not promises
Same-network attendance, remote-desktop and VM detection, screen-capture checks, periodic screenshots, and a live teacher roster.
What students get
Everything to write the exam. Nothing to game it.
Google-Docs-style editor
Headings, bold/italic, lists, quotes, adjustable text size, live word count, and autosave so nothing is lost.
Teacher timer
Optional countdown that auto-submits and locks the essay when time runs out. Server-stamped so it cannot be reset.
Approved PDFs
Reference files open inline beside the essay. Read the source while you write.
Locked browser
Whitelist a whole site or a single page. Links off the list are blocked, popups are killed, no escape.
Teacher review
Scroll every student's essay like Google Classroom, with submission status and proctoring context.
Auto-updates
Signed, notarized builds that update themselves in the background. Never mid-exam.
How it works
Three steps. No accounts for students.
-
1
Teacher builds the assignment
Write the prompt, set a word limit and timer, attach PDFs, and pick which websites are allowed. Start a session and share the 6-digit join code.
-
2
Student joins with the code
Weft runs the environment check. Green across the board means a full-screen, locked writing room. Anything red means the student fixes it or stays blocked.
-
3
Live roster + essay review
Watch every student's status in real time, then read their finished essays side by side. Grades can flow to your Blackbaud gradebook.
Proctoring
Six checks, two outcomes: clean or flagged.
Same network as teacher
Public-IP match. Off-network sessions are blocked.
No remote desktop
RDP, SSH, VNC, macOS Screen Sharing, Chrome Remote Desktop, TeamViewer and more. Detected and refused.
No screen sharing
Dozens of capture apps detected, with one-click "close them for me."
Single display
Extra monitors are flagged to the teacher.
Not a VM
VMware, Parallels, VirtualBox, Hyper-V, QEMU, Xen.
Tamper-proof build
A signed, notarized app with an integrity check that refuses to launch if it has been modified.
Integrations
Plugs into the gradebook you already use.
First-class Blackbaud SKY API integration: pull your class roster and write scores straight to the assignment. No re-typing grades, no spreadsheet gymnastics.
