HookFlow.ai — AI Trend Intelligence Digest

Week of March 23, 2026

Trend Summary

Veo's score hit the hard ceiling at 100 with a +37 seven-day delta — the single largest weekly gain in the tracker — signaling a dominant moment for AI video generation that's pulling the entire AI Image/Video category up +74.5% WoW. The story underneath that headline, however, is more complex: the very tools adjacent to Veo in the AI Video space are collapsing, with Hailuo AI down -30 and Murf AI down -5, suggesting Veo is consolidating attention rather than expanding the category. Meanwhile, AI Models/APIs leads all category gains at +80.6% WoW, pointing to continued infrastructure-layer momentum that developers should be tracking closely.

Emerging Tools to Watch

Veed.io | Score: 23 | 7d delta: 0

Flat isn't always bad. Veed.io is holding position in Captions & Editing while adjacent AI Video tools collapse around it. With the broader AI Image/Video category posting +74.5% WoW growth, a tool that isn't declining is quietly outperforming its peers on a relative basis. Any Veo-driven interest in video workflows could funnel into Veed.io as an editing layer.

Colossyan | Score: 26 | 7d delta: -2

A modest -2 delta in a category (AI Avatars) down -40.9% WoW means Colossyan is losing ground more slowly than the field. Enterprise avatar use cases remain structurally distinct from consumer video generation, and if the category rotation stabilizes, Colossyan is better positioned than most to recover first.

Upstash | Score: 27 | Velocity: +4.0/day | Spikes: HN

Technically filed under Weak Signal, but the +4.0/day velocity over the last 3 days warrants emerging-tool attention. Developer infrastructure is a crowded space, but HN spikes are one of the most reliable leading indicators in this dataset for dev-tool breakouts.

Category Momentum Shifts

AI Models / APIs (+80.6% WoW, avg score 67): The clear momentum leader across 7 tools. This is foundational layer demand — developers are building, and the infrastructure beneath AI applications is absorbing significant attention.

AI Image / Video (+74.5% WoW, avg score 44.5): Veo is the engine here. The category average masks extreme concentration — pull Veo's 100 out and the remaining tools look considerably weaker.

Email Marketing (+42.7% WoW, avg score 53.5): The quietest big gainer this week. Only 2 tools tracked, but a +42.7% WoW move in a niche that rarely generates hype deserves a second look. This may be AI automation demand spilling into outbound workflows.

Writing & Copy (-51.5% WoW): Anyword's -16 delta is the headline, but the category-wide collapse suggests broader fatigue with AI writing tools, not a single-tool story. Commoditization pressure is visible in the data.

AI Avatars (-40.9% WoW): Colossyan's -2 delta looks contained until you see the category context. The avatar space is in contraction — likely attention being reallocated to generative video.

Weak Signal Radar

Tidycal | Score: 26 | Velocity: +5.3/day | HN spike

Highest raw velocity in the dataset at +5.3/day over 3 days. Scheduling and productivity tooling doesn't often generate this kind of dev-community traction. Worth monitoring for a second consecutive HN appearance, which would confirm signal over noise.

Upstash | Score: 27 | Velocity: +4.0/day | HN spike

Serverless Redis/Kafka tooling with developer community traction. The Code Assistant category is up +35.8% WoW — infrastructure adjacent to that wave has a natural current behind it.

Intercom Fin | Score: 56 | Velocity: +3.3/day | HN spike

Already the highest absolute score of the three at 56, making this the least "pre-viral" of the radar entries but the most likely to convert velocity into a sustained score jump. AI customer support is structurally tied to AI Automation (+35% WoW).

Forecast: Next 7 Days

Forecast data is flagged as insufficient for high-confidence projections this week. Based on trajectory analysis:

• Veo is mathematically constrained at 100 — the story next week is whether it holds or begins to decay from peak saturation. Watch for delta normalization toward +10 to +15.
• Tidycal — if +5.3/day velocity holds for another 72 hours, a projected score of ~36–40 by week's end is plausible. Confidence: Low.
• Intercom Fin — at +3.3/day from a 56 base, a score in the low-to-mid 60s by March 30 is directionally supported. Confidence: Medium.

Cooling Off

ElevenLabs | Score: 18 | 7d delta: -16

The steepest Voice & Audio decline in the dataset. A -16 delta from an already-low 18 base puts ElevenLabs at risk of dropping below meaningful tracking thresholds. This is notable given its historical prominence — market attention appears to be actively rotating away.

Hailuo AI | Score: 22 | 7d delta: -30

The largest absolute weekly decline in the entire dataset. Even within a category boosted by Veo, Hailuo lost 30 points — a direct signal that Veo is cannibalizing attention, not lifting all boats.
