Pair AI Suggestions with Rules for Metadata-Rich Filenames

As our marketing org scaled, we leaned on filename.bot and similar AI assistants to capture context human uploaders forget. By combining AI prompts with deterministic rules, every asset carries the who, what, and when teams need without manual typing. This hybrid approach—AI for intelligence, rules for reliability—has transformed our asset management from reactive cleanup to proactive structure. Here's how we built a system that leverages AI's contextual understanding while maintaining the consistency that downstream automation demands.

The AI naming opportunity and challenge

AI-powered naming solves a real problem: humans are inconsistent. One person names a webinar recording `Webinar_Final.mp4`, another uses `Q1_Webinar_04-16.mp4`, a third goes with `Growth_Tactics_Recorded_Session.mp4`. All refer to the same content, but downstream systems can't parse these varying formats reliably. Search becomes guesswork. Automation breaks because regex patterns can't account for every variation. Metadata extraction fails when structure is unpredictable.

AI models trained on content analysis can suggest filenames that actually describe what's inside. Unlike template-based approaches that rely on users selecting the right options, AI reads the document, watches the video, or analyzes the image, then proposes names that capture topics, participants, dates, and context. This intelligence eliminates the cognitive load on users while improving metadata quality beyond what manual entry achieves.

The challenge: AI alone isn't reliable enough for production. Models hallucinate dates, misspell names, suggest filenames with forbidden characters, and occasionally produce nonsense. While 95% accurate sounds impressive, that 5% error rate means dozens or hundreds of bad filenames per week at scale. The solution isn't abandoning AI—it's layering deterministic validation that catches errors while preserving AI's contextual advantages.

Start with structured prompts

We feed the AI helper brief-level context: campaign, channel, audience, and release date. The bot analyzes file contents and suggests a filename like `CampaignX_Webinar_GrowthOps_20250428_v1`. If confidence falls below 90%, the uploader must confirm or edit before proceeding. This prompt engineering matters—generic prompts like "suggest a filename" produce generic results. Specific prompts that include company naming conventions and examples of good filenames produce dramatically better suggestions.

Our prompt template includes: organizational context (industry, common terminology), structural requirements (token order, separator characters), example good names from our library, and specific metadata to extract (dates, people, topics, deliverable type). The AI model receives this context plus the file itself, then generates candidates that already conform to most of our standards. This front-loaded context reduces correction needs significantly compared to post-hoc cleanup.

We implemented confidence scoring that AI models naturally provide but often gets ignored. When confidence exceeds 90%, the suggestion auto-applies and users barely notice. Between 70-90%, the suggestion appears but requires user confirmation. Below 70%, the AI admits it doesn't understand the content and falls back to a template-based form. This tiered approach prevents over-reliance on AI while automating the clear cases that represent most files.

Blend AI with deterministic rules

Inspired by filename.bot's guidance, we enforce guardrails that strip forbidden characters, normalize dates, and append version counters. The AI proposes, Renamed.to validates, and only then do we commit the rename. This hybrid approach prevents hallucinated data from sneaking into production. Validation happens in layers: character whitelist, length limits, date format verification, duplicate detection, and organizational policy checks.

Character validation catches OS-specific forbidden characters (slashes, colons, pipes) and enforces our internal standards (underscores instead of spaces, hyphens for compound words, no special symbols). Date validation parses AI-suggested dates, confirms they're reasonable (not in distant past or far future), and normalizes to ISO-8601 format. Version validation ensures version numbers follow our v01, v02 pattern rather than AI's occasional v1.0 or version1 variants.

Duplicate detection runs before finalization. The validation layer checks if the proposed filename already exists in our asset library. If so, it automatically appends an incremental counter rather than letting the AI suggest something that would cause collisions. This prevents the silent overwriting that plagued our early AI naming experiments.

Train the AI on your context

Generic AI models understand language but not your business. We fine-tuned models with our past six months of manually curated filenames as training data. The model learned our campaign naming schemes, how we abbreviate business units, which metadata matters most, and patterns that distinguish different asset types. Fine-tuning dramatically improved relevance—suggestions went from technically correct but generic to contextually perfect for our operations.

For teams without ML expertise or budget for fine-tuning, few-shot prompting achieves similar results. Include 5-10 examples of perfect filenames in the prompt alongside the file being named. The AI infers patterns from examples and generates candidates matching that style. This lightweight approach delivers 70-80% of fine-tuning's benefit with zero specialized knowledge required.

We version our prompts in Git alongside other infrastructure configuration. When we discover edge cases AI handles poorly, we update the prompt with clarifying examples. When naming conventions evolve, we revise prompt instructions. Treating prompts as production code rather than afterthought configurations keeps AI behavior predictable and improvable.

Handle failures gracefully

AI will fail. Network timeouts, model errors, ambiguous content—many scenarios prevent generating suggestions. Our system degrades gracefully: first attempt with AI, fall back to template-based naming if AI unavailable, escalate to human review if template can't determine essential metadata. This failover hierarchy ensures files always get named even when AI infrastructure has issues.

We maintain a failure log that captures what AI struggled with. Weekly reviews identify patterns: repeatedly failing to extract speaker names from certain video formats, confused by multi-page PDFs with inconsistent headers, misinterpreting abbreviations specific to our industry. These insights drive targeted improvements to prompts, fine-tuning data, or fallback templates. Failure analysis transforms errors from frustrations into systematic improvements.

Push context downstream

Once renamed, Zapier reads the structured tokens, updates Airtable campaign records, and notifies stakeholders in Slack. If a file relates to paid media, an additional automation posts the final filename to the finance tracker so billing can reconcile spend. The structured naming that AI generates becomes the foundation for automatic metadata propagation across all systems. What starts as intelligent renaming cascades into comprehensive content operations.

Downstream systems parse standardized filenames to populate their own metadata fields. Marketing automation extracts campaign codes and channels. Analytics dashboards segment performance by deliverable type parsed from names. Finance systems match invoices to assets by client names embedded in filenames. This systematic reuse justifies the upfront investment in AI-powered naming—the value compounds across every system that consumes the files.

Measure AI effectiveness

We track multiple metrics: acceptance rate (percentage of AI suggestions users apply without editing), edit distance (how much users modify suggestions), error rate (suggestions that fail validation), and time saved versus manual naming. These metrics prove AI's value and guide optimization. High acceptance with minimal edits indicates well-tuned AI. High edit distance suggests prompt improvements needed. Frequent validation failures mean guardrails should tighten or AI training should expand.

Balance automation with human judgment

Not every file should be auto-renamed. High-stakes assets—legal contracts, financial reports, compliance documents—require human review even when AI confidence is high. We flag sensitive content types for mandatory approval before rename applies. This selective automation focuses AI on repetitive, low-risk scenarios while preserving human oversight where consequences of errors are severe.

Users can always override AI. Every suggestion includes an "edit" button that opens the full template form. Power users who know exactly what name they want bypass AI entirely with a manual mode. This flexibility prevents AI from becoming a bottleneck when humans have better context or when edge cases arise that AI can't handle yet.

Future: multimodal understanding

Current AI naming primarily analyzes text—OCR from PDFs, transcripts from videos, metadata from images. Emerging multimodal models understand visual content, audio tone, document layout, and relationships between elements. We're piloting systems that watch recorded webinars to identify key moments, extract topics without transcription, and suggest filenames capturing not just title but actual content highlights. These advances will make AI naming even more contextually rich while maintaining the validation layer that keeps results reliable.
