RotoAlpha is fantasy football draft intelligence built on your league's own history. Paste your league's past draft results (works with any platform, no account linking) and it fingerprints every manager: who reaches, who chases runs, who overpays at which position. The rival tendency report is free.

Free tools with no signup: an auction values calculator that prices the full draftable pool for any league shape (team count, budget, flex and superflex, standard, half PPR, PPR, or custom point values), with the option to upload your own projections CSV and reprice the board off your numbers, and a mock draft simulator with an AI strategist commenting on picks in real time. The one time Season Pass covers draft night and weekly in-season reads. Made by a solo developer; the methodology is published openly.

Castmint turns one typed line into a finished vertical short: AI script, voiceover, synced captions and visuals — ready to post on TikTok, YouTube Shorts and Instagram Reels.

The problem: short-form video is the highest-leverage format on the internet, but every single short costs an evening — scripting, recording a voiceover, syncing captions, hunting for visuals, cutting it vertical. That's why most channels go quiet.

What Castmint does: type a topic — "5 underrated productivity apps", "why your houseplants keep dying" — and Castmint assembles the whole thing:

• Script — an AI-written hook and narration matched to short-form pacing
• Voiceover — natural AI voices (no camera, no mic, no face needed)
• Captions — word-timed, styled, burned in
• Visuals — matched to the script, cut into a vertical 9:16 video
• Editor — timeline editing of text, captions, images and audio when you want control
• Publishing — push finished videos to YouTube and TikTok directly from the app

Who it's for: faceless channels, creators who hate editing, and small brands that want to look active on TikTok, Reels and Shorts without a video team.

One input, whole pipeline: most tools automate a single step — voiceover, or captions, or stock clips. Castmint goes from a typed idea to a finished, publishable short in one pass, and still gives you a timeline editor for control.

Your first three videos are free, no card required.
