TextCortex
Pros
- + Extension rewrites land in roughly two seconds in my tests across Gmail, Google Docs and Notion with no tab switching
- + Model Hub avoids provider lock-in — you can pick the model per task instead of accepting one vendor's default
- + Scheduled agents ran unattended for a full week in my test and delivered results to my inbox as promised
- + Free plan is substantive: knowledge bases, custom agents, connectors and deep research with 50 MB storage at no cost
- + Enterprise admin surface (SSO/SCIM/SAML, dedicated deployment, centralised billing) is documented rather than vapour
Cons
- - Two live vendor price sources disagree ($29.99/user/month on the pricing page vs from $5.59/month in the help centre) — the buyer's quote is the one that counts
- - Retrieval cited the wrong internal document when my knowledge base held overlapping material
- - Rewrite output reads generic and flat; third-party detector tests flag it heavily and my samples agreed
- - Included model usage is metered and premium models burn it fast — read the usage-limits article before budgeting
- - Agent configuration has a real learning curve; the no-code claim understates the setup effort for useful agents
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
