Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Gamma
- Free plan limited to 400 non-renewable credits, requiring paid plan quickly
- Credit rollover capped at 2x monthly allocation, forcing month-to-month spending
- Refund window limited to 3 days with usage thresholds restricting claims
- Per-seat pricing on team plans increases costs for large organizations
- Studio Mode limited to Ultra plan, restricting advanced editing to highest tier
LINE WORKS
- The external LINE bridge, which is the main reason to choose it, only matters where LINE has consumer penetration, so buyers outside Japan, Taiwan and Thailand are paying for a feature they cannot use.
- The free tier caps total storage at 5GB across the whole organisation, not per user, so a team sharing photos or documents exhausts it within weeks and is pushed onto a paid plan.
- Business email is only on the Advanced plan at 800 yen per user, so an organisation wanting both chat and mail pays nearly double the Standard rate for every seat including staff who only chat.
- Developer documentation, support and the integration catalogue are strongest in Japanese, which makes it awkward to administer from a non-Japanese IT function.
- It has no serious developer or engineering workflow story, so organisations that also run Slack or Teams for technical teams end up maintaining two chat systems and two directories.
