New · Screenshot solve for coding rounds

Your quiet cue in every interview.

Dertos AI listens to your call, spots each question and streams a clear answer in a small overlay that's hidden from screen sharing. It's grounded in your resume and the job, and your data stays on your computer.

Works alongside the tools your interviews already use

  • Zoom
  • Google Meet
  • Microsoft Teams
  • Webex
  • CoderPad
  • HackerRank
  • and any app that plays audio

Meeting auto-detect works for Zoom, Google Meet, Teams and Webex in the desktop app. Names are trademarks of their owners; no affiliation.

Three steps from join to answer

Set it up once. On the call, you just talk.

Step 1: Add your context.

Upload your resume and notes, paste the job description and add custom instructions. Dertos AI uses only the parts relevant to each question.

Step 2: Join your call.

Open Zoom, Meet, Teams or Webex. Dertos AI notices the meeting and offers to start. It transcribes the interviewer and you on separate channels.

Step 3: Get your cue.

When a question ends, a concise answer streams into the overlay. Need it now? Press ⌘↩. Want it shorter, more detailed or as code? One click.

Everything you need during the call

Real features, built for the moment someone asks you a question.

  • Live two-way transcript

    The interviewer (system audio) and you (mic), labelled and live. Mute either channel with a click.

  • Automatic question detection

    Answers start the moment a question ends. Turn auto-answer off and use the hotkey instead.

  • Answers in your style

    Concise bullets, full answer, STAR for behavioural questions, or a technical deep dive.

  • One-click follow-ups

    Regenerate, Shorter, More detail or As code. Ask your own with Chat.

    Multiple documents per profile (PDF, DOCX, TXT, MD), plus the job description, company notes and up to 20,000 characters of instructions.

  • 78 languages

    Transcribe and answer in your language, or let answers follow the language of the question.

  • Mock interview practice

    The AI asks role-specific questions, listens to your answer and scores it, with strengths, improvements and a sample answer.

  • AI notes after every call

    A summary, the questions asked, key topics, follow-ups and, for interviews, strengths to keep.

  • History you can search

    Transcripts, answers and notes. Search, rate answers, export to Markdown or JSON, auto-delete after N days.

Built to stay out of the shot

Dertos AI uses your operating system's content protection, so the overlay and the Settings window don't show up in screen shares, recordings or screenshots.

Drag the handle or use the arrow keys. Left: your screen with the overlay. Right: what a screen share shows.

  • Hidden from screen share and recordings.

    OS-level content protection keeps the overlay and Settings out of shared screens and captures.

  • No Dock icon, no menu-bar icon.

    Hide Dertos AI from the Dock and ⌘-Tab. The menu-bar icon is off by default.

  • Normal cursor.

    Your pointer stays a regular arrow over the overlay. No hand cursor to give it away on a shared screen.

  • Click-through mode.

    Clicks pass through the gaps to the app underneath. Toggle with ⌘⇧T.

  • Your data stays local.

    Sessions, documents and screenshots stay on your computer. Keys are encrypted with your Keychain.

  • Offline mode.

    Run fully offline with Whisper and Ollama. Nothing leaves your machine.

Good to know: macOS always shows its own microphone and screen-recording indicators, and no app can hide them. System file pickers can't be hidden either. In the Chrome web app, share a single tab or window, never your entire screen.

Coding round? Snap it. Solve it.

Press one key to capture the screen. Dertos AI reads the problem and the conversation so far, then answers in a format you can talk through.

  • Queue up to 5 screenshots for long problems.
  • Fix or optimise the code that's already on screen.
  • Highlighted, copyable code with time and space complexity.
  • The overlay is never in your screenshot.

Questions, answered

Dertos AI is a real-time AI copilot for interviews and meetings. A small overlay transcribes the call, detects questions and streams suggested answers based on your resume, notes and the job description. It also solves coding questions from screenshots, runs mock interviews and writes notes after each call.

It listens to the interviewer's audio and starts an answer when a question ends. You can turn auto-answer off and press ⌘↩ (Answer now) whenever you like, or type a question with ⌘⇧C.

Yes: one free 10-minute session with no card needed, so you can try the full experience.

Credits are for occasional use. Half a credit covers one 30-minute call session or mock interview, so one credit is an hour. Bigger packs include free bonus credits: 8 credits for the price of 6, 15 for the price of 9.

In the desktop app, the overlay and the Settings window use your operating system's content protection, so they don't appear in screen shares, recordings or screenshots. Dertos AI can also hide from the Dock and ⌘-Tab, the menu-bar icon is off by default, and the cursor stays a normal arrow over the overlay.

macOS always shows its own microphone and screen-recording indicators, and no app can hide them. System file pickers can't be hidden. In the Chrome web app, a browser tab can't be hidden from a full-screen share, so share a single tab or window instead. We don't claim Dertos AI is invisible to everything.

On your computer. Settings, history, documents and screenshots stay local, and API keys are encrypted with your macOS Keychain. The only network traffic is your own requests to the providers you choose; offline mode sends nothing.

Anthropic Claude, OpenAI, Google Gemini (free tier available), Ollama on your own machine, or any OpenAI-compatible endpoint. Transcription uses Deepgram, OpenAI Realtime or offline Whisper.
