You hear the question. You see the answer.
A complete, speakable, finance-grade answer on your screen before you'd naturally start talking. On your screen only.
Windows may show a SmartScreen warning on first launch — see why, and how to proceed.
"Fast" means the whole answer, not the first word.
Most assistants show a first word quickly — then type for 15 seconds while you stall. HintFlow completes a 200–300-word answer in under a second.

Three bullets you can absorb instantly — enough to open your mouth.
A full spoken-register answer — it sounds like you, not a chatbot.
Follow-ups and counterarguments, one keypress away. All three arrive together.
It answers as you, for this seat.
Before each session you set the firm, the role, and the JD — and drop in your own materials: resume, deal sheet, notes. Every answer is grounded in them and written in a finance register, not chatbot prose.
1,800+ questions from interviews that actually happened.
Collected from screens and superdays at the firms below, curated with model answers and follow-up chains by 10+ working professionals.

Your screen. Your hints. Nobody else's.
Share your screen, take a screenshot, get recorded — the overlay isn't there. Your practice partner sees a normal call, so the pressure stays real. Verify it yourself in the built-in device check.

Before you download
Yes. HintFlow is a new app, and Windows SmartScreen flags installers that haven't yet built up a reputation with Microsoft — this is not a virus warning. Click "More info" then "Run anyway" to continue. We're working on code-signing to remove this prompt in a future release.
The macOS build is in testing — system-audio capture works differently on a Mac and we want it verified on real devices before shipping. Leave your email via [email protected] and we'll notify you when it's ready.
No. HintFlow is built for mock-interview practice between study partners. Using it for undisclosed assistance in a real interview, exam, or assessment violates our Terms of Service and is not something we support.
Unused session packs are refundable within 14 days of purchase. See the full Refund Policy for partial-use and Sprint Monthly Pass terms.
