Stop switching tools: here's which AI tool to use for each job, and whether to keep the one you already have.

Each job gets:


1. Make a short talking-avatar video

The pick: HeyGen

Alternative: Synthesia, for training videos. The free Basic plan gives 10 min of video, 3 survey responses and 500 credits per month (watermarked).

Already on Synthesia? Keep it for training videos. Try HeyGen's free plan if you mostly make short social clips. Tested by our team See if you should switch →


2. Build a simple website without code

The pick: Framer

Free option: Carrd, free to start. Pro Standard is $19/year (up to 10 sites, custom domain).

Already on Wix or Squarespace? Keep it if your site does the job. Try Framer if you want more design freedom without code. Tested by our team See if you should switch →


3. Automate email follow-ups from Gmail

The pick: GMass

Free option: Auto Follow Up It!, a Chrome extension that sends the follow-up from your Gmail if there's no reply and cancels it if they answer. Free tier available. Check current pricing.

Caution: Only email people who know you. Automated follow-ups to cold lists are the fastest way to land in spam.

Already using Mailmeteor or Streak? Keep it if your follow-ups run fine. Try GMass if you need multi-step sequences at higher volume. Tested by our team See if you should switch →


4. Research a market fast

The pick: Perplexity Pro

Free option: Gemini Deep Research, in the Gemini app without a paid plan, within usage limits.

Already paying for ChatGPT or Gemini? Keep it: both have a deep research mode. Try Perplexity's free plan if you want every claim cited. Tested by our team See if you should switch →


5. Add captions to a talking video

The pick: Descript

Free option: YouTube automatic captions, if the video lives on YouTube: captions are generated after upload; review and fix them in YouTube Studio → Subtitles.

Already on CapCut? Keep it if you pay for Pro. On the free plan, try YouTube's free captions or Descript. Tested by our team See if you should switch →
