Spellar AI is a bot-free meeting note taker built by Spellar LTD for professionals who want their conversations captured without a bot joining the call. The app records directly on the user's Mac, iPhone, or iPad, so no participant appears in the meeting, and it produces transcripts in many languages with intelligent language detection. At the end of each meeting Spellar generates a structured summary that highlights key points and action items, and it offers customizable summary templates so the output can match different meeting types. A distinguishing feature is its model flexibility: users can switch between AI models such as different GPT, Gemini, Claude, and Perplexity options per meeting, per template, or per question, and a real-time copilot can assist during the conversation. Privacy is configurable: server-side transcription is opt-in rather than default, and users can run transcription on-device or bring their own AI key to keep calls private. Spellar syncs across macOS, iOS, and the web, and supports one-click export to tools like Notion, Jira, Linear, and Google Docs. It suits sales reps, consultants, and professionals who want discreet capture plus flexible, exportable meeting notes. Pricing varies by plan. Check the official website for current pricing.
