This repository is publicly accessible, but you have to accept the conditions to access its files and content.
This dataset holds real conversations that people published from ChatGPT, Claude, Gemini, Grok and other assistants, collected from the open web. It contains personal information people chose to share and material that is offensive, explicit or harmful. Access is approved by hand, for research. By requesting access you agree to: use the dataset under CC BY-NC 4.0 (non-commercial, attribution), the terms the embedded ShareChat rows carry; make no attempt to identify the people in these conversations or to infer sensitive personal data about them; apply your own filtering and safety measures before training or evaluating models on it; respect the terms of service of the platforms the conversations came from; not redistribute the dataset; and delete any conversation the maintainers notify you has been removed.

sharetrawl
244,484 publicly-shared LLM conversations across 9 platforms including toxic output.
Last updated: 2026-09-09
This dataset extends ShareChat (paper) and is updated weekly. 75,226 of its 244,484 urls came from ShareChat's list (31%) rather than from our own discovery.

Motivation
Public chat datasets lag live traffic by 6 to 12 months (WildChat-4.8M → July 2025; ShareChat → October 2025); and often redact harmful/toxic output (e.g. WildChat-Full). This limits research into in-the-wild safety harms and makes benchmarking monitors on real-world use-cases challenging.
Composition
| platform | conversations |
|---|---|
| chatgpt | 114,198 |
| grok | 80,297 |
| gemini | 18,967 |
| perplexity | 17,696 |
| claude | 7,936 |
| manus | 2,126 |
| qwen | 1,151 |
| deepseek | 1,124 |
| kimi | 989 |
| total | 244,484 |
Time distribution
The earlier of created_at (when the conversation happened) and captured_at (when we fetched
it).
| year | conversations |
|---|---|
| 2022 | 8 |
| 2023 | 16,604 |
| 2024 | 27,769 |
| 2025 | 85,604 |
| 2026 | 104,778 (to 2026-09) |
234,763 of 244,484 conversations carry one of the two dates; the remaining 9,721 appear in no year above, having neither.
Harm labels
labels/sharetrawl_broad_labels.parquet scores 243,997 conversations with a two-stage cascade: a cheap gate
(z-ai/glm-5.3-flash) admits anything scoring ≥ 5, and a stronger oracle
(claude-opus-4-8) gives each admitted conversation a 0–100 score and a list of categories. Both
scores are stored (gate_score, opus_score); flagged is oracle score ≥ 50, and
14,998 (6.15%) are flagged.
Evidence window: whole-conversation (labelled 2026-09-08, declared in
labels/METADATA.json): both stages read the whole conversation, in windows of
40,000 characters with the strongest verdict kept (n_windows, windowed).
51 rows (50 of them flagged) have no url at all.
The gate's misses are measured: on 2026-09-08, 2,000 gate-rejected conversations were scored by the oracle and 1 of 2,000 came back flagged — a false-negative rate of 0.05% (95% CI 0.01–0.28%), or roughly 76 missed flags (at most 429) across the 151,783 rejected. The true rate over the labelled subset is therefore likely near 6.18% (at most 6.32%), not 6.15%.
By category
A conversation can carry several categories, so these sum to more than the flagged total. Categories with 10 conversations or fewer are omitted.
| category | conversations |
|---|---|
| misinformation | 12,564 |
| deception | 6,807 |
| defamation | 4,057 |
| hate_harassment | 2,424 |
| privacy | 2,253 |
| sexual | 1,921 |
| other | 1,776 |
| jailbreak | 1,173 |
| illicit | 1,099 |
| self_harm | 783 |
| violence | 503 |
| unknown | 496 |
| cyber | 483 |
| cbrn | 326 |
| harassment | 251 |
| harassment_hate | 20 |
By platform
| platform | flagged | scored | rate |
|---|---|---|---|
| grok | 8,318 | 80,196 | 10.37% |
| kimi | 91 | 989 | 9.20% |
| deepseek | 96 | 1,100 | 8.73% |
| claude | 574 | 7,847 | 7.31% |
| qwen | 57 | 1,148 | 4.97% |
| chatgpt | 4,714 | 114,008 | 4.13% |
| manus | 86 | 2,122 | 4.05% |
| gemini | 660 | 18,925 | 3.49% |
| perplexity | 402 | 17,662 | 2.28% |
By source slice
| slice | flagged | scored | rate |
|---|---|---|---|
| sharetrawl | 14,562 | 234,280 | 6.22% |
| sharechat | 436 | 9,717 | 4.49% |
The gap is primarily platform mix, not corpus: within platform, text-deduplicated, the two are broadly comparable.
To break the rate down by where a URL was found, group on provenance_source; it is set on
154,392 of 243,997 scored conversations, absent on the earliest-discovered
rows, and thin enough per backend that small denominators dominate.
Turn-level labels
The cascade above scores whole conversations. Separate classifier layers additionally score every text-carrying turn, which is the unit ShareChat and WildChat report on.
| layer | model | flagged when | flagged | scored | rate | coverage |
|---|---|---|---|---|---|---|
| Detoxify | unitary/toxic-bert |
toxicity >= 0.5 |
33,645 | 1,985,426 | 1.69% | 79.9% |
| Llama Guard 3 1B | meta-llama/Llama-Guard-3-1B |
p_unsafe >= 0.9 |
95,373 | 1,985,426 | 4.80% | 79.9% |
| OpenAI Moderation † | omni-moderation-latest |
flagged, the file's own boolean |
39,803 | 1,426,296 | 2.79% | 57.4% |
| Broad cascade (turn-level) | claude-haiku-4-5-20251001 → claude-opus-4-8 |
flagged, the file's own boolean |
72,977 | 2,451,844 | 2.98% | 98.7% |
† OpenAI Moderation is still being scored. It walks the corpus in file order, so its coverage concentrates in the platforms early in the scan and is not a random sample — group by platform before trusting its rate.
Data structure
One row per conversation (not per message, unlike ShareChat's CSV release), with the turns
nested in a messages list.
| column | meaning |
|---|---|
platform |
responder platform (chatgpt, grok, gemini, perplexity, claude, manus, qwen, deepseek, kimi) |
url |
the public share URL |
source |
whose copy of a conversation this row is — sharechat (base census) or sharetrawl (our own capture) — not which corpus first found it |
provenance_source |
which discovery backend found the URL (github, wayback, …) |
provenance_ref |
the exact item that surfaced it — an archive snapshot, a scan record, or the public post, repo file or forum thread where the link was shared |
model |
responder model, where the platform discloses it |
created_at / published_at |
conversation timestamps, where available |
captured_at |
when we captured it — set only on fresh rows |
topic / language |
classified topic and language — ShareChat's labels on base rows; language on our own captures is identified by Claude Sonnet |
turns_count |
number of turns |
messages |
list of {message_index, role, plain_text, thinking, code, analysis, version} |
published_urls.sha256 lists the sha256 of every url any retained revision has carried since
the repository's history was last purged, one per line — a superset of this revision's rows, label
files included. It is how a publish knows whether a since-withheld conversation was ever public
(see Removal requests), and it lets you check whether a url has appeared in this dataset without
downloading the parquets.
How the fresh slice is collected
Share URLs are discovered by unioning many backends — web archives, passive-scan corpora (urlscan.io, AlienVault OTX), code search (GitHub, SourceGraph), social/forum search (Bluesky, Reddit, Hacker News, Lemmy) and WeChat public-article search (Sogou) — then de-duplicated against what is already stored. Each URL is rendered in a real browser (please reach out for the HAR files).
Safety and exclusions
Child-safety material is excluded via an automatic screen that runs before every publish and fails
closed — a classifier refusal quarantines rather than passes, and a capture whose screen call
did not complete is withheld until a later run clears it. Quarantined conversations are held in a
content-free denylist of hashed URLs (no text, no URLs) and never enter the corpus. In the label
file, rows categorised csae retain the score and category but have url and id blanked.
These are real conversations from the open web. They contain personal information people chose to share, and material that is offensive, explicit, or harmful.
Removal requests
If you are in one of these conversations and want it removed, or you hold rights in one, open a
discussion on this dataset's Community tab with the share URL (the url value). A removed
conversation leaves the corpus at the next weekly publish, and that publish purges the
repository's history (squashes it to one commit), so the conversation does not persist in an
earlier revision. Otherwise revisions are kept. Removals are recorded as a content-free list of
hashed URLs, never as the URL itself.
Limitations
- Shared conversations are not representative of all usage. People share what is interesting, impressive, funny, or outrageous.
- Platform mix is uneven and shifts over time, driven by what is discoverable rather than by real platform share.
- Harm labels are model judgements, not human annotated nor the truth.
