NovelAI
Pros
- + Lorebook world memory kept names, relationships and character details consistent across long test generations in ways plain prompting does not
- + Vibe Transfer held character appearance (hair, eyes, costume) coherent across varied poses — the best anime consistency tooling I have tested
- + Unlimited text generation from $10/month with TTS on every paid tier is strong value against metered competitors
- + Free trial needs no card: 50 text actions, 30 images up to 1024x1024, 100 TTS generations
- + You own everything you generate, commercial use is permitted, and the documentation states the ownership position plainly
Cons
- - Real learning curve — good output depends on tuning sampling settings and prompts; the out-of-box experience disappoints chat-assistant expectations
- - No free tier beyond the one-time trial, and trial actions never refresh
- - Open content policy permitting adult material rules it out for workplace or classroom deployment
- - Image generations are session-based; closing the tab empties the history queue unless you download the zip first (I lost a batch this way)
- - Anlas costs for premium image work stack on top of the subscription, and one source's Scroll allocation (1,500/month) conflicts with another's (1,000)
Grammarly AI
Pros
- + The correction engine caught every mechanical error in my corrupted test sample, and Pro's sentence rewrites fixed wordy-but-not-wrong prose
- + Works in webmail, document editors and support forms with zero setup — corrections follow you across every text field
- + Tone detector gave a useful second opinion before sending sensitive messages in my testing
- + Team layer (style guide, brand tones, analytics) is mature enough for real organisational enforcement
- + Enterprise governance is real: SAML SSO, SCIM, DLP, BYOK, audit-log API, and a published SOC 2 (Type 2) attestation
Cons
- - Long-form generation is filler-level without heavy steering; there is no manuscript or article drafting workflow
- - Free tier's 100 AI prompts/month runs out fast if rewrites are part of every message; full-sentence rewrites are Pro-only
- - Per-member pricing scales steeply — ten seats at $12/member/month annually is $1,440/year before Enterprise
- - AI-text and plagiarism detectors are probabilistic signals, not verdicts; risky as academic evidence
- - Everything typed through the extension is processed by a third party, and the Superhuman-era corporate changes may reshape the product
