## MakeAudio

MakeAudio splits its product into two halves. The first is a text-to-speech engine: you paste or upload text, choose one of 14 supported languages and one of nine voices, then download the rendered audio in MP3, WAV, AAC, Opus, FLAC or PCM. Each conversion accepts up to 200,000 characters, and billing is consumption-based rather than a subscription — you buy credits, and one credit covers one character of speech. The second half is a broad set of self-serve utilities for audio, video, music and sound testing.

The utility tools work directly in the browser, which is why the site advertises no file-size limit: your own device does the processing, and the only ceiling is available memory. Free visitors get two uses per day of the utility tools with no upload-size cap; a paid plan removes both the daily limit and the ads, at $15 for one month or $30 for three months. Audio transcription is metered separately, at one credit per second of audio, so an hour of recording works out to roughly $1 in credits.

Because text-to-speech is charged per character rather than per seat, MakeAudio suits creators and teams with irregular volumes better than a flat monthly voice subscription. Practical things to keep in mind: credits are purchased in a $5 minimum block, expire one year after purchase, and speech limits of 200,000 characters per job mean very long manuscripts need to be split. Check the current pricing page before budgeting, since rates can change.

**Pricing & Plans:** Freemium plus pay-as-you-go. Utility tools are free with a two-use daily cap; unlimited access costs $15/month or $30 for three months. Text-to-speech credits are sold at $1 = 15,000 credits (one credit per character, $5 minimum). Audio transcription runs at $1 = 3,600 credits (one credit per second, about $1 per hour of audio). Credits expire one year after purchase.

- **14-language text to speech:** Convert text into speech in English, Spanish, French, German, Italian, Dutch, Danish, Norwegian, Swedish, Portuguese, Chinese, Japanese, Korean and Turkish.
- **Nine human-like voices and six export formats:** Choose from voices including Alloy, Ash, Coral, Echo, Fable, Onyx, Nova and Shimmer, then download as MP3, WAV, AAC, Opus, FLAC or PCM depending on whether you need mobile playback, editing headroom, streaming efficiency or lossless archiving.
- **Browser-based media utilities:** Convert, trim and merge audio, convert, compress and trim video, and generate tones, binaural beats, white, pink and brown noise, all client-side with no upload size limit.
- **Sound and hearing test tools:** Check headphones and speakers with dedicated headphone, surround sound, bass, subwoofer and hearing tests before you commit to a mix or a listening setup.
- **Consumption-based billing:** Speech and transcription are charged per character and per second respectively, so you pay for what you actually render instead of a recurring seat fee.

**Strengths:** No subscription required for speech — you buy credits and use them when you need them; Six output formats covering playback, editing, streaming and lossless archiving; Up to 200,000 characters per conversion, far more than most single-paste tools; Large free utility toolbox that works in the browser with no file-size limit

**Limitations:** Utilities are capped at two uses per day unless you pay, which is limiting for heavy batch work; Credits expire one year after purchase and the minimum top-up is $5; There is no permanent free tier for text to speech — you must buy credits to use it; Very large utility jobs depend on your own device's memory, so weaker machines can struggle

## Studocu

Studocu is a study platform for students that revolves around a shared global library of study documents. Rather than generating everything from scratch, it relies on students themselves — when someone uploads their lecture notes, summaries, study guides or past exams, other students searching for the same course, university or topic can find them. This makes Studocu especially useful for courses where a set of well-organised notes or a previous exam is worth more than any textbook chapter. It operates across many countries with a large user base, and materials are organised by course and institution so you can narrow down to what is actually relevant to you.

On top of the document library, Studocu has added an AI layer that fits naturally into student workflows. There is a study assistant for asking questions, tools that generate notes and summaries from your documents, quiz generation and flashcards for active recall, and text-to-speech so you can listen to study material instead of reading it. Together these features turn a plain PDF of notes into something closer to a revision kit — the document provides the source, and the AI tools reshape it into summaries, practice questions and flashcards you can drill.

Studocu is a freemium service. Creating an account and previewing documents is free, but full unlimited downloads, an ad-free experience and the premium AI study features sit behind a subscription. The platform also rewards contribution: uploading your own documents and engaging with classmates earns points that can be redeemed for downloads, so active contributors can offset the cost. Because access is guarded by bot protection, automated tools and some VPN users occasionally hit a temporary access block, which is a security measure rather than an outage. Studocu suits students who want a fast route to course-specific material and a way to turn it into active study rather than passive reading.

**Pricing & Plans:** Studocu uses a freemium model. Signing up and previewing shared documents is free, while unlimited downloads, ad-free browsing and the full AI study toolkit are offered through a paid subscription. You can also earn points by uploading your own study documents and redeem them for premium access, and regional plans and prices vary, so check the official site for current details.

- **Global document library:** Search a vast, student-contributed library of lecture notes, summaries, study guides and past exams organised by course and institution.
- **AI notes and summaries:** Generate notes, summaries and revision material from documents so you can study the essentials instead of re-reading everything.
- **Quizzes and flashcards:** Turn study material into interactive quizzes and flashcards so you can test yourself and target weak spots.
- **Text-to-speech:** Use built-in text-to-speech to listen to study documents on the go, useful for revision during commutes or downtime.
- **Upload and earn points:** Upload your own documents to earn points that can be redeemed for premium download access, alongside the option to subscribe.

**Strengths:** Huge global library of real student-contributed lecture notes and past exams; AI study tools turn documents into summaries, quizzes and flashcards; Points system rewards uploading your own material and can offset premium costs; Local libraries and multilingual support across many countries

**Limitations:** Full downloads and unlimited access are gated behind a paid subscription; Bot protection temporarily blocks some visitors, which can frustrate access; Quality of user-uploaded study materials varies by course; Some regions may not be fully covered by the local document library
