Live coaching while the call is still on.
OffBook listens from your machine, surfaces cues in the corner of your screen, and never joins the meeting as a bot. Capture, coach on signal, then ship a debrief and follow-up draft when you hang up — one workflow for reps who care about the next sentence, not just the recap.
Most AI meeting tools optimize the archive. OffBook optimizes the live moment: what you say while the prospect is still in the room.

What you see across one call
Pre-call
Select the right profile and objective template so coaching context matches the call intent.
Mid-call
Receive live prompts tied to signal shifts, objection patterns, and momentum changes.
Post-call
Get a debrief and follow-up draft quickly so the next step is clear and shareable.
Capture
OffBook captures call audio in the browser through `getDisplayMedia` and `getUserMedia`, then streams it securely for low-latency transcription and analysis. The goal is simple: capture the right signal without adding meeting friction.
Coach
Live coaching cues appear while the conversation is in motion. Instead of remembering to take perfect notes, you get practical prompt suggestions at the moment they matter.
Signal
OffBook highlights buying intent, objection risk, and momentum changes as the call unfolds. This creates a decision surface in real time, not just a report afterward.
Debrief
After each call, OffBook generates a clean debrief and follow-up draft so your next action is clear. This compresses the time from conversation to execution.
Playbook
Your Personal Playbook learns from your call history and profile setup. Suggestions get more specific over time instead of repeating generic coaching language.
Privacy
OffBook uses user-initiated browser capture, requires explicit per-session consent confirmation, and keeps prompts visible only to you. We do not train on customer audio or transcripts by default.
Architecture snapshot
Browser audio streams through encrypted transport to transcription and model services, then returns as live coaching cues. The pipeline is optimized for low-latency interaction rather than delayed batch processing.
Browser capture -> encrypted stream -> transcription + model inference -> live coaching panel -> debrief generation
Each segment in this pipeline is designed to reduce avoidable delay. Capture starts in the browser to keep setup lightweight. Streaming transport keeps signal current while the call is active. Model processing is tuned for actionable outputs, not long-form analysis artifacts.
This architecture choice reflects product intent. OffBook is not primarily a historical intelligence warehouse. It is a live decision assistant with post-call execution support. Data artifacts exist to support that loop, not to replace it.
In practical deployment terms, teams get value faster when they treat architecture and workflow as one system. Profile configuration, cue usage, and debrief follow-through must align with the call operating model. That alignment is where durable ROI appears.
Security posture is also tied to architecture. Browser-side capture and explicit user initiation reduce meeting-party visibility concerns, while encrypted transport and controlled storage boundaries preserve trust for high-stakes conversations.
For technical evaluators, the right test is latency under realistic call conditions and output usefulness under actual team prompts. Benchmarks without operational context often miss what matters to end users.
FAQ
Q
Is OffBook only for sales calls?
No. It also supports founder, recruiting, customer success, and consulting call workflows through profile context.
Q
How is this different from note-taking tools?
Most note tools optimize post-call artifact quality. OffBook optimizes in-call decision quality and immediate next-step execution.
Q
What is the best way to evaluate OffBook?
Run a two-week pilot on one high-stakes call type and compare objection handling quality and follow-up turnaround time.
Q
How long does implementation take for one operator?
Most individual users can configure a first profile and run a live call workflow in one session, then refine prompts over the first week.
Q
Can I keep my existing meeting stack while testing OffBook?
Yes. OffBook can be piloted on selected call types while existing tools remain unchanged for lower-priority workflows.
Q
How does OffBook handle consent and two-party states?
Before each call session, OffBook requires an explicit confirmation that participants were notified and any required consent has been obtained.
Q
Do you train on customer audio or transcripts?
No. OffBook does not train on customer audio or transcripts by default, and in-call prompts are only shown to the user running OffBook.
Q
What does success look like during the trial?
Success usually means cleaner next-step capture, faster follow-up, improved objection handling quality, and stronger confidence in call outcomes — often visible within your first few coached calls.
