As answered by people managing JSFiddle and TENEKS.
TENEKS's answer:
Companies with structured sales organizations that already invest in their sales process. Specifically:
TENEKS is built for teams that take coaching seriously and want to turn their existing call recording infrastructure into an always-on coaching engine.
TENEKS's answer:
TENEKS scores 100% of your sales calls — not random 2% samples — and finds the exact sales behaviors that are leaking revenue. While most conversation intelligence tools analyze calls after they end, TENEKS works during and after the conversation, detecting deal-killers across every stage (Intro, Discovery, Pitch, Closing) and delivering real-time coaching suggestions to reps on screen.
What sets it apart: - Full call coverage: every client call is scored automatically, so revenue patterns hiding in the other 98% are surfaced - Deal-killer detection: pinpoints specific behaviors like pitching before confirming pain, missed follow-up questions, or weak objection handling — and attaches a revenue impact to each - European language support: built from the ground up for 100+ languages including Nordic, Baltic, Estonian, and Polish — languages where most competitors fall short on transcription and speaker separation - 4-minute setup: desktop app for Windows/macOS or web platform, no IT tickets or admin permissions needed, works with Zoom, Teams, Meet, or any VOIP
TENEKS's answer:
Most competitors like Gong or Chorus focus on post-call analytics — by the time their feedback reaches the rep, the deal is already cold. TENEKS intervenes in the moment, giving reps on-screen coaching suggestions while they're still talking to the prospect.
Key reasons to choose TENEKS: - Real-time coaching, not post-mortem reports: managers set the weekly coaching focus on Monday, reps get live guidance during calls, and progress is tracked by Friday - Better diagnosis: TENEKS doesn't just say "the call was bad" — it tells you the rep pitched in the first 90 seconds without asking a follow-up question, and that this pattern costs you a specific amount in lost revenue - European language support that actually works: built from the ground up for 100+ languages including Nordic, Baltic, Estonian, and Polish — with accurate transcription and speaker separation in languages where most US-built competitors perform poorly - Self-refining playbook: the system learns from your top closers' winning patterns and builds a playbook that writes and improves itself over time - No workflow disruption: installs in 4 minutes, works with existing tools (Zoom, Teams, Meet, any VOIP), no IT involvement required
TENEKS's answer:
TENEKS was born from a real problem the founder experienced firsthand. While working in Saudi Arabia, he was tackling the challenge of sales conversation intelligence for Arabic dialects — a space where modern tools performed poorly at both transcription and speaker separation.
During a Christmas visit home to Estonia, he realized that the same technology gap existed for Estonian and other European languages. The tools built by US companies simply weren't designed for smaller, more complex languages — and the sales teams using them were getting subpar results.
When Ramadan arrived in Saudi Arabia, the founder returned to Estonia to incorporate the company. TENEKS was built from day one to solve the language problem that larger competitors ignore: delivering accurate, reliable sales intelligence in languages like Estonian, Nordic, Baltic, Polish, and Arabic — where transcription quality and speaker separation actually matter for coaching to work.
What started as a language-first approach to conversation intelligence evolved into a full live sales coaching platform that scores every call, detects deal-killing behaviors, and helps managers coach their teams more effectively.
TENEKS's answer:
TENEKS is built on a modern, scalable stack:
This architecture allows TENEKS to deliver sub-second coaching prompts during live calls while still performing comprehensive post-call analysis across 100+ languages.

Test your javascript, CSS, HTML or coffeescript online with jsfiddle code editor. Jsfiddle – code playground.
JSFiddle cannot be used to host code on your server. The code has to be on JSFiddle and is public all the time.
What is missing from JSFiddle is live previews. You have to basically refresh the page by clicking on the play button. And compared to other playgrounds, JSFiddle is probably the slowest. Another slightly frustrating...
