DescriptReview: edit video by editing the text

Riverside Agents adds four AI helpers to Riverside's recording studio. Producer preps the session, down to suggesting eight questions worth asking your guest. Editor turns the raw recording into an episode: it tightens pacing, cleans up audio, cuts filler words, switches layouts, and adds captions and branding. Clipper finds the moments worth posting and cuts them. Marketer writes the captions and the newsletter and schedules the posts. You decide how much to hand over. Any step can stay manual, and nothing is published until you approve it. The agents also work on old recordings, so a back catalog can be clipped and promoted again. For businesses, the same crew sets up a webinar's registration page, invites, and run of show. Agents ship on every plan, on web and mobile. Pro is $29 a month, or $24 billed yearly, with 2,000 AI credits. Extras like AI B-roll spend credits when an agent uses them.

ToneCraft turns a recording or a script into a voice-over you can publish. Upload audio or video, check the transcript with each speaker labeled, edit the lines, then pick a new voice from 56 options. Twenty-six come with every plan, and the other 30 need a paid plan. You can export MP3, WAV or a timed SRT subtitle file. There's a two-speaker demo on the homepage you can try without an account, but transcribing your own files needs a sign-in. The free plan gives you 25,000 characters a month, with a spoken outro added. Creator is $7 a month after 14 free days, which covers about three hours of audio. Channel is $15, and Pro is $39 with no trial. It won't clone a real person's voice, and it won't put the new audio back onto your video for you. For cloning, look at ElevenLabs.

Viggle takes a still image of a character and makes it move. Give it a picture plus a reference video or a text prompt, and its JST-1 model maps realistic movement onto the character: walking, dancing, gesturing. The motion has weight to it, so the character looks like it's standing on the ground instead of floating. It started out on Discord and now has web and mobile apps, which makes it much easier to pick up. The free plan gives you five videos a day. The limits are real. Clips run under 15 seconds, there's no audio, and beyond the preset animation styles you can't customize much. It's fun to play with and good for quick social clips and memes. Don't expect an animation studio.

Spira Maxima is a video model from Spira that turns a written script into a finished social media video. It's for creators and brands that post short UGC-style videos and don't want to film or edit them. You paste a script, and Spira casts a presenter that fits the topic, adds B-roll and motion graphics timed to the narration, and finishes with captions and music. You can upload a photo and a voice sample to make an AI clone of yourself as the presenter, or add your own product shots and phone footage for it to edit around. Spira can then schedule and post the video to TikTok, Instagram, YouTube, X and LinkedIn.
