IdeaFast vs Karmo

IdeaFast reads recent posts in chosen subreddits, groups repeated frustrations into scored problems with linked threads, and proposes product angles founders could build.

Karmo studies the speech, visuals and pacing of a public Instagram Reel or TikTok, then drafts a fresh script and shot list matched to the creator's audience.

About IdeaFast

IdeaFast is a research tool that mines Reddit for recurring problems people describe. Founders choose one or more subreddits, and the scan groups posts into pain points scored from 0 to 100, each showing who has the issue, what they are asking for, a suggested build angle and links to the original threads. Signals like willingness to pay or requests for a tool are flagged. Paid packs add more subreddits per scan, a three month lookback, more generated ideas and validation reports, with PDF, CSV and JSON exports. There is no subscription, only scan packs bought once: the first scan is free, then 19 USD buys 40 scans and 49 USD buys 100.

About Karmo

Karmo is a video analysis tool for creators and marketers who save short videos for inspiration but struggle to turn them into their own content. Given a supported public Instagram Reel or TikTok, it examines the spoken words along with the opening, cuts and on screen demonstration, rather than relying on a transcript alone. It then writes a new script and shot list using the creator's voice, niche, audience and goal. The site is explicit that Karmo does not generate finished videos, edit, schedule posts or predict virality. Source videos are deleted after processing, and credits are refunded if a job fails. Paid plans start at 19 USD per month.
