Comparisons
Two tools, the same five questions, and when to pick each one.
ChatGPT vs Claude
On paper the two are close: both give you ownership of the output and both cap usage without publishing numbers. Claude shows clearer prices; ChatGPT is a little kinder when you want to leave, with a discretionary refund on individual plans if you ask within seven days, where Claude's consumer terms say payments are non-refundable. On both, check the training setting the day you sign up.
ChatGPT vs Google Gemini
Gemini wins on price if you already pay Google for storage, since AI Pro bundles 5 TB and more. ChatGPT wins on terms: OpenAI assigns you the rights in the output, and its training opt-out keeps your history, while Gemini keeps chats that human reviewers have seen for up to three years, even after you delete them.
ChatGPT vs Perplexity
These are different tools: a general assistant against a cited-answer search engine. On terms, ChatGPT is clearly safer to pay for. It assigns you the output, where Perplexity limits consumer plans to personal, non-commercial use and keeps refund windows of 24 to 72 hours outside the EU and UK.
Aragon AI vs HeadshotPro
Both sell one-time headshot packs, delete your selfies within about 30 days and assign you the photos. HeadshotPro has the edge on fine print: plain one-time prices, team credits that never expire and an explicit promise not to train on your photos. With Aragon, a single download counts as using the product, which closes the refund.
HeyGen vs Synthesia
HeyGen is friendlier on credits (one extra month of rollover on monthly plans) and leaves paid users free to use the output commercially. Synthesia is far stricter on data, with a published commitment not to pre-train on customer inputs or outputs, but every purchase is non-refundable and its stock avatars are licensed only while you subscribe. Your choice depends on whether your footage or your budget is more sensitive.
Jasper vs Grammarly
Grammarly is the safer buy for most writers: a useful free plan, clear ownership of your text and a training setting you can switch off. Jasper targets marketing teams. Its pricing page says it does not train on your data, but its terms let it use inputs and outputs to improve its own models, and a free trial bills without a reminder.
Otter.ai vs Descript
Otter records and summarizes meetings; Descript edits audio and video by editing the transcript. On fine print Descript comes out ahead: a visible switch keeps your recordings out of AI work, and plan refunds are possible if you ask within 48 hours. Otter says subscriptions are non-refundable and its privacy policy describes training on de-identified recordings and transcripts with no opt-out offered. Neither rolls unused minutes or credits over.
