## Memo Card (LectMate)

Memo Card (the product formerly branded as LectMate) is built around a single idea: a lecture should stay connected to everything you make from it. Instead of generating an untraceable summary, the workspace streams live transcription while the lecturer speaks, places translated text directly beside the original speech, and then structures the same transcript into bilingual notes, keyword summaries, a timestamped mind map, quizzes, and AI Tutor explanations that cite where in the lesson each claim came from.

The workflow spans capture, translate, organize, and review. Students can start a live session in a modern browser before class, upload an existing recording later, or use the companion browser extension, with speaker separation applied to recordings so multi-voice lectures remain readable. After class the service cleans punctuation, extracts key ideas, and builds study material next to the bilingual transcript, while search and replay let a learner jump to the exact moment behind any note at a comfortable speed.

Privacy handling is an explicit part of the design: recordings, transcripts, translations, notes, and exports sit under scoped access with short-lived links, and users can delete individual sessions or their whole account from settings. Pricing is prepaid rather than subscription-only, with an annual unlimited plan and credit packs consumed by lecture minutes, so light users and heavy users can both choose a predictable path.

**Pricing & Plans:** Prepaid model with no mandatory subscription: a $299 one-time Annual Unlimited plan covering a full year of unrestricted use, a 2,000-credit pack for $199 (about $0.10 per credit), and a 200-credit starter pack for $29.90 (about $0.15 per credit). Credits are consumed by usage type — recorded uploads use 1 credit per started 5 minutes, realtime transcription 1 per 3 minutes, bilingual caption translation 1 per 2 minutes, and live interpreter audio 3 per minute. Annual access does not auto-renew, and Stripe handles checkout.

- **Live transcription and translation:** Memo Card converts classroom speech to text while the lecturer is still talking and displays translated text next to the original, so students can follow fast delivery, unfamiliar accents, and technical vocabulary in real time.
- **Bilingual notes with source links:** Original speech and translated meaning are preserved together, and every note or AI answer can be traced back to a precise timestamp in the recording for verification before exams.
- **Mind map, summaries, and quizzes:** A linear transcript becomes timestamped branches, keywords, section summaries, course quizzes, and visual recaps, giving a structured entry point without hiding the complete transcript.
- **Search, replay, and export:** Search any term inside a session, open the matching moment, replay the audio at your preferred speed, and export material for revision, group work, or a personal archive.
- **Scoped privacy controls:** Recordings, transcripts, translations, notes, and exports use scoped access and short-lived links, with clear deletion paths for individual sessions or the full account.

**Strengths:** Educational and research-focused context is documented with pricing tailored to real lecture workloads; Prepaid credits and a one-time annual plan avoid a forced recurring subscription; Every AI-generated note or answer stays connected to a timestamp in the original recording; Runs in the browser with explicit deletion paths and scoped access to private class content

**Limitations:** Credit consumption varies sharply by mode, and live interpreter audio is 3 credits per minute, so heavy simultaneous interpretation adds up quickly; Accuracy depends on audio quality, room noise, accents, and network conditions, which the service openly acknowledges; Speech-to-text and translation quality is strongest for the supported major language pairs shown rather than every language combination

## Perplexity

Perplexity is an AI-native answer engine and autonomous research platform designed to replace traditional keyword search and fragmented browser tab workflows. Instead of returning a ranked list of blue links, Perplexity interprets complex natural-language queries, crawls live web indexes, academic databases, financial filings, and social discussions in real time, and synthesizes direct, structured answers anchored by numbered inline citations. Beyond conversational search, the platform has evolved into a broader agentic ecosystem encompassing Perplexity Computer for autonomous multi-step tasks and the Comet AI browser assistant.

Under the hood, Perplexity orchestrates its proprietary web-grounded Sonar model family alongside frontier third-party reasoning models—allowing paid subscribers to route queries through Claude Opus 4 and Sonnet 4, OpenAI's o3-pro and GPT series, or Google's Gemini models, or run parallel evaluations via Model Council. Its Deep Research mode autonomously decomposes intricate questions, conducts dozens of iterative searches across hundreds of primary sources, and compiles exhaustive, exportable briefing reports in minutes. Users can also organize ongoing projects inside Perplexity Spaces, which fuse uploaded private documents (PDFs, CSVs, docs) with live web grounding and custom system instructions.

Perplexity serves an expansive audience ranging from students and journalists to equity analysts, legal researchers, and software engineers. Individual users can rely on the free tier for everyday fact-checking, step up to Perplexity Pro ($20/month) for daily deep research and model switching, or subscribe to Perplexity Max ($200/month) for uncapped high-compute agentic runs. Organizations adopt Enterprise Pro ($40/seat/month) and Enterprise Max ($325/seat/month) for SOC 2 compliance, zero data training guarantees, and internal knowledge connectors, while developers integrate real-time grounded citations into custom software via the Sonar REST API.

**Pricing & Plans:** Offers a permanent Free tier with unlimited Quick Searches, 3 Pro Searches per day, and 1 Deep Research query per month; Perplexity Pro costs $20/month ($200/year) and Perplexity Max costs $200/month ($2,000/year) for individuals. Team plans start at $40/seat/month ($400/seat/year) for Enterprise Pro and $325/seat/month for Enterprise Max, alongside usage-based Sonar API billing.

- **Deep Research Autonomous Reports:** Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
- **Multi-Model Routing & Model Council:** Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
- **Perplexity Spaces & Hybrid RAG:** Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
- **Perplexity Computer & Comet Assistant:** Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
- **Sonar Web-Grounded Developer API:** Exposes Sonar, Sonar Pro, Sonar Reasoning Pro, and Sonar Deep Research over standard HTTP endpoints so developers can embed low-latency, live-cited web intelligence directly into third-party applications.

**Strengths:** Every generated statement links directly to numbered, verifiable web or document sources, drastically reducing ungrounded LLM hallucinations.; Deep Research mode delivers comprehensive, multi-page synthesis reports at a fraction of the time required for manual desk research.; Broad model optionality lets subscribers use Sonar, Claude, OpenAI, and Gemini models under a single $20/month subscription.; Focused search scopes (Academic, Finance, Web, Social) and Spaces allow clean separation between general browsing and domain-specific knowledge work.

**Limitations:** The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.; Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.; Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.
