What is tts4free?
tts4free.com is a free online text-to-speech converter that turns typed text into downloadable audio using Microsoft Edge's online voices. Paste up to 5,000 characters, pick a voice, and hit Convert without creating an account or paying anything.
The site runs on Next.js with edge-tts and pulls from Microsoft's natural-sounding online TTS catalog. A separate VoiceSample page lists voices by language and style so you can preview options before converting your own text.
It fits students, language learners, accessibility users, and anyone who wants written content read aloud in the browser. The interface stays minimal: text box, voice selector, and a single convert action.
Aimi.fm
What is Aimi.fm?
Aimi.fm builds royalty-free music from licensed artist stems instead of scraping copyrighted recordings, then ships that engine through Aimi Sync for video scoring. Upload a clip, and Sync analyzes scenes frame by frame to compose a matching soundtrack with optional vocals, voice-over, and downloadable stems. The public homepage now teases a relaunch, but Sync pricing, docs, and the about page show the company is still shipping tools for creators and developers.
Where prompt-only generators spit out static clips, Aimi Sync treats your video as the prompt and adjusts timing per scene cut. Music comes from the Sonic Vault of human-recorded samples orchestrated by Aimi Script and the AMOS engine, with a ledger logging each stem placement for artist payouts. That sample-first model is why Aimi.fm claims over 60 patents and positions itself against tools trained on major-label catalogs.
Video creators scoring Reels, tutorials, and client work get unlimited exports on paid tiers, with a free plan for 1-minute clips. Independent musicians can upload stems to the Sonic Vault and earn from micro-usage. Developers can request the Sync API to embed scene-aware, copyright-cleared soundtracks in apps without handling licensing themselves.
